I had visited the Australian Audio & AV Show 2011 which was held at the Marriott Hotel in Melbourne over two days. Here I had noticed certain trends being marked out as far as hi-fi and home-theatre technology went.

The old-school of hi-fi lives on with these valve (tube) amps

There was interest in orthodox hi-fi setups where vinyl records or CDs were the main medium of choice. These still appeal to the music listeners who prefer to make a point out of listening to their favourite recordings. Here, there was a large number of amplifiers that were driven by valve (tube) technology which appealed to audiophiles who placed value on the “valve and vinyl” style of hi-fi enjoyment. It even showed that there was still life in the “old girl” that was the classic vinyl record, This was more so with the arrival of newly-issued recordings on what I call “boutique vinyl” i.e. records that were cut for best dynamic range and pressed on heavier discs that were made of new material; with the ability for the purchaser to download MP3s of the same recordings for free.

Marantz CR603 CD receiver

Of course, I had seen the return of Luxman to the hi-fi scene, with their efforts on high-grade CD players and stereo amplifiers, with one of their amplifiers being modelled on a 1970s-era classic of theirs.

Network audio

But the main focus of the show was the use of computer equipment and home networks to play out music through hi-fi systems.

Network setups

A router and DLNA-enabled ReadyNAS is what this show is about

Most manufacturers which were demonstrating network-based hi-fi setups had a small network in their hotel rooms. This typically had a wireless router that was fit for home or small-business use at the “edge” of each of these network and working as the DHCP server; the same as what would be expected for a home network. As well, a lot of the manufacturers hooked a network-attached storage unit like the ReadyNAS to these networks to demonstrate their network-audio equipment.

In some cases, some of the suppliers used computers running DLNA-compliant media server software on the network rather than a NAS. An example of this was NAD who linked a MacBook Pro running Elgato EyeConnect as a media server for their C446 Digital Media Tuner.

Network-audio equipment

NAD c446 Network Media Tuner

Most of the equipment shown was network-audio adaptors which were known by names as “media tuners”, “Internet tuners”, “network media receivers” and similar names. These were components that were connected to existing amplifiers through a line-level connection and could play content on a DLNA media server, USB memory key or Internet-radio services. Some of the units could connect to and control an iPod attached to their USB port.

Some of these are devices that I have cited in a previous article on this site about top-shelf hi-fi names using DLNA as their preferred network-audio infrastructure. Here, I had mentioned about them using this established technology and the high-grade codecs like FLAC so they can concentrate on high-quality clear sound.

Linn Majik DS network preamplifier

Linn had a handful of these devices which worked as control amplifiers for use with power amplifiers or active speakers. These Akurate, Majik and Klimax units could also stream line-level signals or, as I have seen, the output of a turntable (Linn Sondek LP12) playing a record to other Linn network media adaptors.

As well, some of the manufacturers were offering receivers and CD-receiver systems that had DLNA media playback and Internet media access as part of their function set. This included the Rotel RCX-1500 CD receiver that I have previously reviewed on this site. Speaking of which, Rotel’s Australian distributors, International Dynamics are introducing more network-enabled kit from Pro-ject, in the form of another network media adaptor.

Denon even promoted their network-enabled home-theatre receivers a “everyhing”-ceivers because of the multiple functions that they could offer through the home network.

Denon's "everything"-ceiver

All of these setups were based around UPnP AV / DLNA Home Media Networks with Denon, Marantz and B&W demonstrating Apple AirPlay-compliant setups. The sales representatives for most of the various manufacturers had described the UPnP AV / DLNA network setup as an open setup where everyone can “come to the party”. A lot of the setups were controlled using various UPnP AV control points that were running on iPads owned by the various demonstration staff. Some of the control-point apps were branded and optimised for particular manufacturers’ equipment, usually offering control functionality that worked peculiarly with that equipment.

Naim Uniti network CD receiver with Naim's distinct CD-loading tray

Naim and used this show to exhibit their Uniti CD receiver; as well as the UnitiQute network media / FM receiver and the UnitiServer which is their “ripping NAS”. This is a class of NAS which uses an integrated optical drive and software for ripping CDs to the hard disk.

One interesting point that I had noticed was that Loewe had used this event to launch their MediaCenter network-enabled music system. This was equipped with a hard disk and software that allowed you to “rip” the currently-inserted CD to that hard disk, a practice that I had observed with some Philips and other hard-disk-equipped music systems. But this unit was able to share the contents of its hard disk to other UPnP AV client devices as well as become a UPnP AV client device for devices like those NAS units.

How is this becoming relevant to “real” hi-fi?

Loewe Mediacenter media server and player

One reason this is happening is that other Websites, fronted by audiophile recording labels, are offering their recordings for purchase and download as high-bitrate FLAC or, in some cases, WMA files. In some cases, these are copies of the studio-master recordings rather than producer-tuned masters for CD and iTunes distribution.

Here, you could load these files on to a NAS and share them through your network with network media clients of this calibre. Or you could use media-management software to transcode to MP3 for use on most portable players and smartphones or prepare CDs of these files for playback on regular CD players.

Conclusion

What I see of this Australian Audio & AV Show this past weekend is that the home network as a system for storing and playing audio content has earned its stripes as far as high-quality sound reproduction is concerned. This is definitely underpinned through the use of the UPnP AV / DLNA standard for discovering and presenting available media content in these networks.

Introduction

I am reviewing the Sony CMT-MX750Ni Internet-enabled micro music system which is a small-form-factor CD/iPod stereo that can connect to the home network for Internet radio or DLNA-based music playback. It is equipped with a DAB+ digital-radio tuner but there is a version of this system known as the CMT-MX700Ni which doesn’t have this tuner and is available in areas that don’t have Eureka 147 DAB / DAB+  digital-radio services.

From henceforth, I am directing the comments in this review also at the Sony CMT-MX700Ni music system as well as this CMT-MX750Ni, except for any DAB digital-radio comments.

The system itself

Setup and Connection

The CMT-MX750Ni can connect to a network either via Wi-Fi wireless or Ethernet. This allows for flexibility with wired and wireless network setups, such as working with highly-reliable Ethernet and HomePlug networks. You need to use the remote for setting up the music system on a Wi-Fi network that doesn’t use WPS push-button setup. Here, you use the numeric keypad on the remote to enter the WEP or WPA passphrase for your wireless-network segment in an SMS-style manner.

Sony has “reinvented the wheel” when determining how the speakers should be connected to the main unit. Here, they have used a proprietary Molex-style plug at the system end of the speaker cords like they have done with their DVD home theatre systems. Personally, I would prefer that they use a two-conductor 3.5mm phone plug, or the older 2-pin speaker-DIN plug, both of these connections can allow for easier-to-replace, easier-to-modify speaker connection. Infact a lot of the music systems that were sold through the 1970s and 1980s with supplied “separate-piece” speakers, such as the “detachable-speaker” boom-boxes have used either the 3.5mm phone plug, 2-pin speaker-DIN plug or RCA plug to provide “plug-in” speaker connections and these have just worked as well for plug-and-play operation.

The speakers are a typical bass-reflex two-way setup but aren’t aggressively styled. One thing I am pleased about these speakers is that they are well-built and the enclosures use an all-wood construction rather than a plastic front baffle which shows the quality behind the system.

In use

You have the ability to perform basic content-navigation tasks using the controls on the Sony CMT-MX750Ni’s front panel but you need the remote control to use this music system to the fullest. The system uses an “Inverse” LCD display as its display. This yields readable text but Sony could implement a monochrome OLED or fluorescent display rather than the LCD which makes it look “cheap”.

Other than that, when you operate the Sony CMT-MX700Ni or CMT-MX750Ni music systems, you find that you are operating a well-built music system. The switches and mechanisms don’t exhibit any sort of tackiness that can be noticed in a lot of bookshelf music systems. The remote control is relatively large and with it you have one-touch access to the sources and main functions as well as being able to do advanced functionality.

The FM tuner didn’t perform properly on the “pigtail” aerial that was supplied with the unit, especially as it was on the lower level of a split-level house. Here, I would recommend connecting it to a better FM aerial like an outside one if you want the radio to work properly in a difficult scenario.

This setup didn’t challenge the DAB tuner with it able to survey the DAB+ multiplexes in Melbourne and provide clear and reliable reception from any program on these multiplexes.

The CMT-750Ni and CMT-700Ni use an iPod dock that drops down from the front panel. This makes it easier to hide the dock if you are not using an iPod or iPhone with it. As well, the iPod or iPhone can lean against the front panel while plugged in without the need to use any dock adaptors. The only limitation with this is that you need to pull back a hard-to-discover latch before you can close the iPod dock.

The front-panel USB socket allows you to play music of a USB memory key, SD card adaptor or smart phone. But it is “live for power” only when system is in operation and supplies the power when you select other sources so you can charge up your Android smartphone or other USB-connected device. This situation is similarly true for the system’s iPhone dock and it could be tempting for users to dock their iPhone in this CMT-MX750Ni’s dock in order to charge even if the system is not playing. It could have the option to supply power to charge devices connected to the USB socket or iPhone dock even when the Sony music system is in standby.

When the Sony CMT-MX750Ni or CMT-MX700Ni plays Internet radio and loses the connection to the station, it doesn’t try to reconnect to the station unlike the other Internet radio products I have used. Here, it just goes back to the main menu and you have to retune to that station, and this can be annoying with over-subscribed Internet streams. Other than, the Internet radio experience works properly as best as the link can allow.

This system works as an audio device in the DLNA Home Media Network. This includes the ability to play audio content that is “pushed” to it from a DLNA-compliant control point like Windows Media Player or TwonkyMedia Controller. It serves this function properly whether you pull the content up using the unit’s control surface or push the content out using a DLNA control point.

These music systems can work in the “Party Streaming” mode where multiple Sony receivers or music systems connected to the same home network can stream the same content at the same time. The CMT-MX700Ni or CMT-MX750Ni systems can work as either a host or a client system in this aspect.

Sound Quality

There is the ability with these Sony music systems to adjust the tone of the sound system. This can only be done using the remote control and you have to press the EQ button on that controller. Here you have access to bass and treble adjustments but you can also enable a “Dynamic Sound Generator” mode using a separate button. This may add “extra bite” to some recordings but may not yield difference with other recordings and may be about providing “big speaker” sound out of small speakers.

The sound quality is typical for a high-end “micro” form-factor music system but can clip or sound “muddled” around just near the maximum volume point. I have observed this with recent popular RnB music which is tuned for a loud sound with excessive bass but It can “go loud” on recordings that weren’t tuned “loud”, although I have had the CMT-MX750Ni run at “flat” tone settings.

I even ran this system on a DAB+ broadcast of an ABC Radio National program and had noticed that the speech from the show’s presenters came through very clear, crisp and intelligible. This didn’t matter whether it was a man or woman speaking in the show.

Limitation and Points Of Improvement

The “pigtail” aerials (antennas) supplied for DAB and FM use are inadequate for reliable FM or original-specification DAB digital radio (UK, Denmark, etc). As well, these supplied antennas remind you of using the typical clock radio which has this kind of FM aerial and are out of character with this system’s class. It could do better with a “whip-style” aerial similar to what is used for the Wi-Fi network connectivity and could support “single-input” aerial setups through an option.

Other connectivity improvement that It could also benefit from include having a pair of RCA line-input connectors or a “tape-loop” set of input and output RCA connectors on the back of the system for whenever you connect a computer, tape deck or other piece of audio-equipment in a semi-permanent manner. It can also benefit from a headphone jack for private listening purposes. Similarly, it could also benefit from integrated Bluetooth A2DP functionality so it can work with phones and media players that use this medium as a way of transmitting music data.

iPod dock with fiddly latch that needs to be released to close it

I would also improve the iPod dock so that you don’t have to operate any latches to open or close the dock. As well, I would provide the ability to charge smartphones connected to the USB socket or docked in the iPhone dock while on standby as a user-selected option. This can allow the user to keep an iPhone or other smartphone “topped off” when docked or connected to the system.

Another point of improvement would be to allow the CMT-MX750Ni music system to retry Internet-radio streams if the stream it is tuned to “gives up the ghost”.

I would also like to see the Internet-media and home-network-media functionality implemented into most of Sony’s bookshelf-stereo range and / or for Sony to develop a network-connected CD receiver along the same lines as the Rotel RCX-1500 CD receiver I previously reviewed.

Conclusion

I would recommend purchasing the Sony CMT-MX750Ni or CMT-MX-700Ni network-enabled music systems for use in a small room like a bedroom, den or office. It may work well for use in an apartment’s small living area.

On the other hand, I wouldn’t use this music system in situations where it is expected to fill a large room with music or play in a noisy area like a party or cafe.

Introduction

I am reviewing the Western Digital WDTV Live network media adaptor. This is and adaptor that connects to an external display like a TV, monitor or projector and/or an external amplifier in order to play media files held on a local storage device like a USB memory key or via a small network.

Price

Recommended Retail Price: AUD$299.99

Functions

Connections

The device itself

The unit's remote control

It is a small device about the size of two packets of cigarettes stacked on top of each other and is powered using a power adaptor. Users operate it with a very small remote control that has the main transport functions and a D-pad for navigating around the user interface.

Setup

How this connects to your TV

The device connects to the TV using an AV cable that plugs in to a four-conductor 3.5mm jack on the back of the unit. There is another 3.5mm four-conductor jack for connecting to the component-video connections on a suitably-equipped display device with a separate patch cable. Of course, this unit can be connected to HDMI-equipped display devices like most plasma and LCD TVs; and it has an optical SPDIF socket for connection to equipment with an optical digital input like most surround receivers.

Sadly, this device doesn’t support connection to display devices that use RGB inputs in any form. This may affect those of us who want the best out of monitors or projectors that use such connectors like most SCART-equipped European TVs, business-focused “data projectors”, classic “3-gun” projectors or professional-grade video displays. You may get around this by connecting the device to the display via one of the “HDFury” HDMI-RGB adaptors

It has the ability to play media that is held on USB-attached storage devices like memory keys or USB hard drives. This can be useful for playing media that you have held on one of these devices.

As for video codecs and file types, it can natively handle most audio and video file types including the DivX and Matroska MKV family of file and codec types.

Network setup

The WDTV Live HD can be connected directly to an Ethernet network or HomePlug AV network with the appropriate “homeplug” bridge device, But it is one of these “wireless-ready” devices that connects to a Wi-Fi network using an optional Wi-Fi dongle available from Western Digital or through one of their retailers.

Use

This can work with any display device including older TVs

The user interface is a “full-screen” one which works to the edge of the screen. This may be of concern with those of us who have hooked the WDTV Live up to an older CRT-based TV set that has the orthodox curved screen edges. As well, the logos for the Internet services are rendered in a dull manner and could benefit from “true-colour” display with a highlight around the currently-selected service.

Of course, there is a screen-saver function which can be overridden for displays that aren’t affected by long-time display of images or set to appear after a time between 5 minutes to 15 minutes. Here, it just shows the WD logo; but could show now-playing information during audio playback.

Online services

The Facebook service has the expected functions like viewing one’s own news feed, contributing to a Status Update or writing one’s Status Update as well as the ability to view one’s Photo Albums or a Friend’s Photo Albums. All text entry is based on “pick-n-choose” methods and the pictures do come up properly on the full screen.

I have tested the YouTube service with this device and have used it to play some videos including the service’s “poster child” video which is the “Keyboard Cat” video. The user interface is what would be expected for a 10’ interface and the users would be required to use the “pick-n-choose” method for any text entry like account login or video searching.

The “Tune In” Internet-radio function works properly for Internet radio access and allows the Internet radio stream to play in the background while you navigate the menus. During the day, It had performed well on quality-of-service when streaming Internet radio; but like all Internet services, this will depend on how congested the connection is.

UPnP AV / DLNA media access

The UPnP AV / DLNA functionality on the WDTV Live works properly when you use the remote control to call up the content on your UPnP AV / DLNA Media Server. In previous firmwares, this media player had problems when playing out media under the control of a UPnP AV Control Point like Windows 7 or TwonkyManager. Here, it would play only one item at a time and require the user to advance the media to the next item using the remote control or the Control Point.

Now, units that have firmware newer than version 1.65 can play multi-item playlists and slideshows without needing to be “pushed on”. There is still a problem with this function, especially with image slideshows and video playlists where the unit will show its menu every time a new image or video is loaded up before it plays that image. This could be improved with “read-ahead” buffering for subsequent media items.

Limitations and Points Of Improvement

I would like to see the user-interface improved in various ways, such as use of brighter colours or full-colour logos for the Internet services.  The screen-saver could also support “service-driven” behaviour like showing now-playing information for audio sources.

As well, this device could benefit from integration with local online-video services like the local “catch-up TV / video-on-demand” services offered by the local TV stations. Of course, I would like to see an improvement on the media changeover behaviour when the device is used as a UPnP AV / DLNA MediaRenderer under the control of an external control point.

This device’s form factor could be taken further with an integrated digital-TV tuner for implementation as a digital-TV set-top box that could have online and network media access as well as digital-TV access.

Conclusion

I would recommend the Western Digital WDTV Live or any of its successor models as a cost-effective device that can be useful for pressing a cheap or old TV, monitor or projector in to service as a network media playback device in the UPnP AV / DLNA Home Media Network.

Smart TVs (A Current Affair article) – NineMSN VIDEO

My Comments

From the recent “A Current Affair” broadcast on the Nine Network, it seems to me that the “Smart TV” or “Internet TV” concept is now ready for prime time.

What is this trend all about?

This is where functionality like access to IPTV channels, “catch-up” TV and video-on-demand is now being integrated in to most of the big-name TV sets that are to be sold at the likes of Harvey Norman. It will also include an “app-store” interface so that users can add functions to these sets in a similar way to how they add functions to a smartphone or tablet computer.

Some of the sets will come with an integrated hard disk which will provide PVR functionality. But what wasn’t mentioned was that most of the sets from the big brands, especially LG, Samsung and Sony, will support integration with the DLNA Home Media Network. This means that these sets could play content held on a computer or network-attached storage device that uses this standards-based technology.

Typically, these functions will be pitched at TVs targeted for the main viewing area i.e. the main lounge room or family room. But this kind of function may be added to existing sets through the use of some of the current-issue Blu-Ray players and network-media adaptors like the Sony SN-M1000P network media adaptor.

A few key questions that I have

“TV plus Apps” or IPTV and interactive-TV content?

There could be a fear that this could turn out as “TV plus apps” with the same old TV content plus some apps such as clients for the popular social networks, photo-sharing sites and YouTube-type sites thrown in.

But some providers are making ties with the various manufacturers to set up free and pay-TV front-ends through the IPTVs. Examples of this include Samsung establishing a tie with BigPond TV to provide direct access to that content or most of the manufacturers running ABC iView through their TV sets. It may also open up opportunities like video-on-demand or boutique content services. As well, once there is a level playing field for adding TV services, this could lead to the addition of extra TV content.

If there is a desire to provide new live or on-demand IPTV services, there needs to be support for adding the newer services to existing IPTV equipment. This could be achieved through an always-live app store on these sets. Similarly, existing broadcast content, both editorial and advertising, must be able to support links to apps and interactive front-ends that are accessible to the average viewer with one click of a particular button through the use of interactive-TV content-delivery standards.

This can include applications ranging from interactive games and competitions that are part of children’s TV through “play-along” quiz shows to polls run in conjunction with current-affairs shows which have the option for you to view “extended-version” interviews.

Equipment Useability

A key issue that I have raised in this site was the useability of services like the Social Web on this class of equipment. Typically, the “smart TV” concept prides itself on connection with social-network services like Twitter and Facebook; but there will be the desire to gain access to photo-sharing sites like Flickr and Picasa or gain full benefit from sites like YouTube. These can make use of “smart-TV” services more daunting for someone who doesn’t find themselves competent or isn’t experienced with technology.

An example of this was when I mentioned to a friend of mine about the Pixel Eyes app on the TiVo platform where they could view their Picasa albums through the lounge-room TV connected to the TiVo PVR. I mentioned that they would have to log in to their Google account using the “pick-pick” method of entering their credentials in order to view their pictures on this service and this idea frightened them off it.

The main problems is that different users will want to log in to this common terminal or, in the case of the Social Web, leave comments in relation to what they are viewing. Typically, this will require a fair bit of text entry and most remote controls won’t be fully engineered to cater to this requirement. The user will typically have to work a D-pad or wave a Wii-style “magic remote” around to pick letters from an onscreen keyboard and may have to switch between logical keyboards to use different character sets like numbers, different-case characters or punctuation. Try entering in a Facebook / Twitter / Google username and password that way or “knocking out” a Tweet that way.  As well, I have raised in that same article methods in which logging in to these services from devices like TVs and set-top boxes can be simplified and referenced how Facebook achieved a login experience suitable for these devices with their HP ePrint app. This includes being able to change the active user associated with a TV or set-top box to another user.

Similarly, I would look at issues like keyboard support for IPTVs. This is whether a TV comes with a QWERTY-enabled remote or not. The best method for add-on keyboard support would be to use Bluetooth HID connectivity so that a Bluetooth-based wireless keyboard can be used as a text-entry tool. Similarly, the ability for one to plug a standard USB computer keyboard in to the USB port usually reserved for USB memory keys and use this for text entry may make things easier. This would work well with those wireless-keyboard sets that plug in to the computer’s USB port.

A remote that doesn’t have a QWERTY keyboard but uses a numeric keypad for direct-channel-selection or parental-code-entry could use this keypad as an “SMS-style” text-entry interface, something which many nimble-fingered teenagers are used to. This would work better if it used the character-set-selection practices used on popular mobile phones.

Other methods that can be looked at include the use of smartphone apps as virtual remote controls like what Samsung has done for their Android smartphones. Here, a user could download an app to their Galaxy S phone and have this become the TV remote control. This could be extended to ideas like multi-control for interactive applications such as “own-account” operation for Social Web and similar applications with the TV screen becoming a “common monitor”.

What to consider when choosing or using your network-enabled TV

DLNA functionality

The TVs or set-top devices should support DLNA Media Player functionality at least, with preferable support for DLNA 1.5 Media Renderer functionality. Initially this would give you access to content held on your computer’s or network-attached-storage device’s hard disk.

The Media Renderer functionality can allow the TV to be controlled by a UPnP AV / DLNA control point such as TwonkyMobile, PlugPlayer or Andromote on your smartphone or tablet computer, or TwonkyManager on your netbook.  In the case of Blu-Ray players and set-top devices, you may even be able to play music from your network storage through your favourite stereo without the need to have the TV on to select the music

If the TV or set-top box offers integrated PVR functionality, look for DLNA Media Server compatibility because this may allow you to play recorded TV shows on other TVs in the house without them needing to be of the same brand.

It is also worth noting that some DLNA functions like DLNA server or Media Renderer may not be enabled by default even though the set has these functions. Here, you may have to go to the setup menus and look for “DLNA control”, “Media Server” or similar options and enable them to benefit fully from these functions.

For further information, it is also worth reading the DLNA Networked Media articles that I have written on this site.

• Getting Started with DLNA Network Media Sharing
• Setting up “PC-less” Networked AV
• The 3-Box DLNA Home Media Network

Connecting the set to your home network

When you connect one of these TVs to your home network, I would suggest that you avoid using Wi-Fi wireless connectivity, especially if the TV or set-top box uses a dongle for this connectivity rather than integrated Wi-Fi connectivity. This is because of the fact the Wi-Fi network is radio-based and if anything is shifted slightly between the Wi-Fi router and the TV, you may have service-reliability issues.

Instead, I would recommend that you use a wired method such as Ethernet cable or a HomePlug AV powerline-network setup. The Ethernet-cable solution would work well if the router and TV are in the same room; you have wired your home for Ethernet or you can get away with snaking Ethernet wiring through windows. On the other hand, the HomePlug solution would work well for most users who don’t want to or can’t lay new wiring through their homes because this uses the house’s existing AC wiring.

In fact, if you are renovating or rewiring your home, it may be worth considering wiring the house for Ethernet and making sure you have an Ethernet connection in the main TV-viewing areas of the house. This may be achievable if you have an electrician who is competent or knows one who is competent with communications or data work doing the job.

Conclusion

This site will have regular coverage of home media network issues that will become of importance as we head down the the path towards online home entertainment.

Introduction

I am reviewing the Pure One Flow portable Internet radio which is the younger brother of the Pure Evoke Flow radio that I have reviewed a while ago. This unit is designed along the same lines as the “old-style” portable radio that can be perched on a window sill or the top of a fridge.

Price

Recommended Retail Price: AUD$249

ChargePAK battery pack: AUD$99

Functions

Speakers

The Internet radio

The Pure One Flow is the same size as a midsized portable radio and is housed in a rubberised cabinet with knobs for volume and “select” function and buttons below LCD display. The rubberised casing is a marked difference from the glossy plastic that is used on some radios, which attracts fingerprints and is hard to keep clean. I also like the knobs, especially for the sound volume because it is an interface most of us are accustomed to, where you can just “flick” the knob downwards to turn it down.

Like the Evoke Flow radio that I previously reviewed, this unit can work on AC using a supplied “wall-wart” power adaptor or battery power using a “ChargePAK” rechargeable battery pack that is available as an extra-cost option.

Audio connectivity is in the form of an auxiliary-in jack so you can use the radio as an amplified speaker for your MP3 player or other audio device. It also has a headphone jack which is a connection that I am noticing is becoming increasingly rare for Internet radios. The reason I find this connection important is that you could use an active-speaker system like a pair of computer speakers as better-sounding more-powerful speakers for the radio.

The set works well as a DAB-based digital radio, being able to pick up all of the multiplexes that are broadcast in our area.

For Internet-radio station selection, this unit uses a  “Form style” user interface if you intend to select a smaller group of stations but will give you the complete list of stations if you are just browsing. This is in contrast to the “tree-based” approach that most Internet radios use for selecting stations.

There is also access to a “sounds” service where you can hear sounds like sea wave; as well as access to the “FlowSongs” music download service.

This radio works properly as a DLNA-compliant media player, being able to play most audio file types that are held on UPnP AV media servers.

The sound quality for this set is very similar to an average mid-sized portable radio such as the archetypal transistor radio of the 1960s. It can still fill an average-sized room with music and the sound is focused around the middle frequencies.

Limitations and Points of Improvement

This unit could be improved with the telescopic aerial being used for the Wi-Fi wireless network as well as for FM and DAB radio.  The Wi-Fi functionality could work well with keeping the details for up to five wireless networks, which can be useful if you take the radio between multiple locations, which is something you would be tempted to do more readily with this set.

Another limitation is that you can’t enable daylight-saving time on this set. Instead, when you determine the time zone, you only can set up for standard time. This could be rectified with a firmware update which exposes a “daylight-saving” on-off function or access to a table of “spring-forward / fall-back” times hosted on the manufacturer’s Website.

Another improvement that I would like to see would be to support regular AA, C or D batteries even with a battery cage so you don’t have to look for the hard-to-get ChargePAK battery packs.

Conclusion

This set may be considered as an option when you want to replace that old “transistor radio” with something that gives you access to “modern” radio sources like DAB or Internet radio. It could he very useful where you want a set of this class to be highly rugged and durable.

Introduction

I am reviewing the Pioneer NAC-3 (XW-NAC3) Internet music system with 2 iPod docks. This DLNA-enabled network media unit is a flagship model that heads a series of iPod speaker docks that Pioneer has recently released and is the latest attempt by this company to sell “small-set” audio equipment like portable, clock and table radios.

This Japanese company has always been known for high-quality home audio / video equipment since the 1960s and car audio equipment since the 1970s but has dabbled in the highly-competitive product class at various times through the 70s and 80s, initially selling these goods under the “Centrex” brand in some markets but eventually simply selling them under their own brand. This unit is an example of how Pioneer, along with the other Japanese consumer-electronics companies are trying to get their claws back in to a very competitive product class which is awash with many cheap Chinese-built products that are sold under many different brand names.

As an echo to the earlier attempts in the “small-set” audio product class, this unit has functionality that makes it stand out from the pack. One party piece is to work with 2 iPod or iPhone devices and play tracks from one or both of the devices and another one is to properly implement “three-box” DLNA Network Media functionality where it can be managed by a Windows 7 computer or other DLNA control point.

It will also be the first time I have reviewed a network media device and am implementing these “at-a-glance” tables for this class of device. Regular readers may have noticed that I am implementing these “at a glance” tables when I review laptop computers and printers so people can see the basic facts about these products before they read the review text.

Speakers and Sound Output

The unit itself

Card-type remote control

This unit has been designed to appeal to the young generation who just want something new rather than your “father’s old station-wagon”. Here, it has a shape that is similar to a banana and is finished in a glossy-white plastic cabinet. It can come with three different speaker-cloth colours – burgundy-red, black or white. As well, it comes with a card-size infrared remote control which you have to use for operating most functions including access to Internet radio.

This unit can play music from 2 iPod or iPhone devices; a Bluetooth A2DP-compliant audio source, a USB Mass-Storage Device or a line-level source as well as material over the network. But this set lacks some functions that I have been used to with most Internet radio units that I have reviewed previously on this site.

One function that it misses is the ability to connect to the host network via Wi-Fi wireless. Here, you have to connect it to the network using an Ethernet cable, but you could use a HomePlug kit or a Wi-Fi-Ethernet client bridge to connect it to the home network and want “around-the-home” flexibility without needing to lay Ethernet wiring. The other function that it lacks is access to regular broadcast radio, whether FM or DAB+ digital radio. This may not be of concern if you are seeing this unit as an Internet-enabled complementary radio / network music terminal / iPod speaker doc while you use your ordinary radio (which most households have plenty of) for listening to regular local broadcast radio.

iPod playback

You can play and charge two iPods or iPhones here

The ability to play and charge 2 iPod or iPhone devices is useful for quite a few applications. For example, a person who has one of those high-capacity “iPod Classic” series devices can still use this device as a “jukebox” alongside their new iPhone 4 that they have just signed a contract for. This is infact the demonstration setup that I used with an iPod Classic and an iPhone that I had borrowed from a teenage boy that is living with me.  Similarly, a household with many “iDevices” can this as a charging station for two of these devices. The two-iPod function is augmented by a dual-device shuffle mode which plays tracks from each of these devices sequentially. The iDevices can even be put in to “shuffle” mode so as to allow the unit to randomly pick music across the devices.

Bluetooth A2DP

The system can also work with Bluetooth A2DP audio sources like a lot of mobile phones, tablet computer (including the iPad) or some MP3 players. Here, this worked as a “Bluetooth speaker” for my Nokia N85 mobile phone and had worked as expected. The track navigation and PLAY/PAUSE buttons on the remote control had controlled the music playback on my phone.

The pairing experience was a bit confusing because there was one procedure to set up the paring code but this didn’t make the unit “open for pairing”. You actually had to press the PLAY button on the remote control to achieve this goal and begin the pairing process.

Network functionality

All the media available via the home network connection is accessed when you select “Home Media Gallery” as the function source. This includes the Internet radio as well as music files available from any of the DLNA Home Media servers on your network.

Internet radio

The Internet radio works from the vTuner Internet-radio directory and has the similar directory structure to all of the other radios that I have reviewed. It has the ability to store 30 Internet-radio stations with 10 stations in three “classes”. You will have to use this function once you regularly listen to particular Internet-radio stations because if the set loses connection with the station, you will need to “retune” to that station.

It can handle jitter and latency situations OK but as I have said before, it goes to the “Home Media Gallery” menu once it drops out and loses the connection. This can happen at busy times when the Internet service is oversubscribed and there isn’t proper QoS functionality on the network between the radio station’s server and this set.

DLNA network media

This unit integrates properly with the DLNA Home Media Network. Here, it will work as a network music player where you select your content using the NAC-3’s display and remote control; and it will even list the UPnP AV / DLNA Media Servers that exist on your network when you select the “Home Media Gallery” function so you can start “delving” in to the content on your desired server.

It also works properly as a network-controlled music player when you use a UPnP AV / DLNA control point program like Windows Media Player 12 (Windows 7) or a mobile phone with a DLNA media control program. I have even tried this with my Nokia N85 phone which I use as a personal “Walkman” and have “pushed” music held on the phone to this unit via the home network. As well, unlike some DLNA-compliant media players that are meant to work under network control that I have used, this unit will even play a program of music that you direct it to play from the network-based control device.

Sound Adjustments and Quality

There are bass and treble controls accessible from the remote control but I had kept the bass and treble set at “flat” so as to hear a sound that I can assess fairly. There is a “sound-effect” button which allows the system to be switched between a “vivid” mode with a bit of extra bass and treble, a “Lo-Fi” mode which yields a cheap transistor-radio sound and an “ALC” mode which keeps the sound level constant for use in noisy environments.

Even if I don’t use the sound-effect modes and I have the bass and treble flat, this Internet radio doesn’t sound like a “gutless wonder”. There is still some punchy bass even with popular music that was recorded before there was the desire to make such music sound boomier and louder. Yet you still hear the vocals and instruments that carry the body of the music clearly and distinctly. Even the heavy bass lines from the recent dance tracks that were on the iPod and iPhone that I borrowed from the teenager to try out the dual-iPod functionality didn’t worry this music system much and they still sounded “tight” – there wasn’t that old bass-heavy “jukebox” sound.

Limitations and Points of Improvement

The Pioneer NAC-3 Internet music system could benefit from integrated Wi-Fi wireless-network or HomePlug powerline network connectivity. This is more so because it is the kind of network device that appeals to being taken around the house from room to room.

It could also benefit from a headphone jack because some people use this jack to connect a more-powerful active-speaker system or an amplifier to these devices for increased sound output. As well, the VIDEO output on this unit could be used not just for iPods and iPhones that have a video output. Here, this jack could work with the DLNA network media player to play pictures and video material through a connected TV set.

The Internet radio functionality could have some improvements in the way it operates. It could come back to the “last-tuned” Internet station or attempt to reconnect itself after a dropout. But this may have to be facilitated through a separate “Internet Radio” function on the function selector like what most other Internet radios have.

Conclusion

I would recommend this unit for people who either run two or more iPods or iPhones; a Bluetooth-enabled music-capable phone or have established a DLNA Home Media Network and want a “complementary” transportable device that can get the most out of their digital music library available on their portable devices or home network.

My Comments

I have read the attached article and found that most of the devices had impressed me as devices that would work well in a home or small-business network. This was because of particular abilities that had made the devices unique rather than run-off-the-mill devices.

NeoTV network media players

NeoTV 550 network media player

This group of NeoTV network media players may be very similar to the other network media players  like WDTV Live that are appearing on the market. This is that they are capable of playing audiovisual media held on a USB memory key, camera card reader or external hard drive; or from a DLNA/UPnP-AV-compliant media server that exists on your network. But one of the models in this lineup, the NeoTV 550,  has eSATA connectivity and the ability to be a Blu-Ray Disc player when connected to an optional eSATA-connected Blu-Ray drive. This can benefit people who want to consider running this unit alongside their DVD player as a network media player but may take the plunge for Blu-Ray when they are ready.

At the moment, I am not sure whether this unit can work as a substitute DVD player if it is connected to an eSATA or USB DVD drive or a DVD is loaded in to a connected Blu-Ray drive.

HomePlug AV 802.11n access point

XAVN2001 HomePlug AV 802.11n wireless access point

One device I am pleased to see on the scene is the XAVN2001 HomePlug AV 802.11n wireless access point which work like some of the 802.11g wireless access points that can connect to a HomePlug 1.0 Turbo segment. It is also available as part of the XAVNB2001 kit which includes the Netgear XAV2001 HomePlug AV-Ethernet bridge as well as this access point. Like these other access points, this unit plugs in to the wall and works as a bridge between an Ethernet segment and a HomePlug AV powerline segment as well as being an access point for a 2.4GHz 802.11n wireless network.

This device can work as a way of extending the effective radio footprint of an 802.11n wireless network with the use of an Ethernet or HomePlug AV wired backbone. On the other hand, it could bring an 802.11n wireless network and Ethernet network point in to an outbuilding or static caravan (trailer) in the manner talked about in my feature article “Multi-Building Home Networks”.

Quick extension-access-point setup with WPS

I had done further research about this access point through Netgear’s Web site and found that this unit uses WPS as a way of simplifying the creation of a multiple-access-point wireless-network segment. This kind of segment, also known as an “extended service set” makes use of multiple access points with the same SSID, network operating mode and security parameters so a portable device can move between access points with minimal user intervention. I have written a bit about the concept of using WPS as a way of simplifying setup of a small multi-access-point wireless network in an article I had posted last year on this site at its old location and had moved to the current location.

The user just has to hold down the unit’s ON-OFF button for a few seconds then press the WPS button on the WPS-ready wireless “edge” router to start the configuration routine. A few moments later, they are then able to move the access point to the area where the Wi-Fi network is needed and proceed to connect this access point to the Ethernet or HomePlug AV backbone which the wireless router should be connected to.

Conclusion

If more manufacturers can look towards making affordable and easy-to-use network devices, they can end up with equipment that will appeal to most users and have equipment that is out of the ordinary.
