Onkyo, a home entertainment provider, has announced the release of three new mid- and upper mid-range network A/V receivers for 2010: the TX-NR1008, TX-NR808, and TX-NR708. Each of these models is THX Select2 Plus certified and offers processing and features to support multi-room set-ups, network audio streaming, iPhone/iPod-compatible USB, and 3D capable home theater with multidimensional surround sound to match.

All of these models have seven HDMI 1.4a connections, specifying compatibility with the new 3D video formats. These new receivers are also compatible with the mandatory formats for 3D broadcast content of "Side-By-Side (Half)" and "Top-and-Bottom" 3D video formats.

HDMI is also the conduit for 1080p video upscaling of all video inputs, regardless of native resolution, via Faroudja DCDi Cinema. On all three of the new Onkyo receiver models, DCDi Cinema works to remove jaggies during the video signal deinterlacing process.

Each of these network receivers includes a rear-panel Ethernet port that links it directly to the internet or to a home PC. Users can then listen to a wide range of audio file types, including MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, and LPCM. They can also access a range of different streaming Internet radio services, from Pandora, Rhapsody, vTuner, and Sirius Internet Radio, and newly expanded services from Napster, Mediafly, and Slacker internet radio.

The Ethernet connection offers firmware upgrades. Each receiver is also Windows 7 compatible and DLNA 1.5 certified to allow audio streaming from other network-enabled equipment throughout the home.

Audio processing on all three models includes the lossless codecs Dolby TrueHD and DTS-HD Master Audio. Complementing these are Dolby Pro Logic IIz and Audyssey DSX. The former provides the option of adding extra height channels, while the latter adds either height or width channels. With the 7.2-channel TX-NR808 and TX-NR708, these extra channels replace the surround rear channels. Meanwhile, with the 9.2-channel TX-NR1008, users have a host of different speaker configurations to choose from.

This flexibility extends to multi-room set-ups. Onkyo's new A/V receivers allow for distributed audio in up to three rooms in the home. With the TX-NR708, users can take advantage of a powered Zone 2 or a Zone 2 line out. Meanwhile, the TX-NR808 provides a powered Zone 2, along with pre-outs for Zones 2 and 3. Finally, the TX-NR1008 can deliver 5.1-channel surround sound in the main room, plus fully powered stereo audio of two different sources in Zone 2 and Zone 3.

Along with the two extra amplifier channels and one extra HDMI output, the TX-NR1008 offers further advantages over its two siblings. It is equipped with advanced ISF video calibration controls for independent optimization and fine-grained adjustments of every video source. And it sports an extra 192 kHz/24-bit Burr Brown DAC to handle the heavy demands of multi-channel audio processing.

Each of the three Onkyo models includes a full suite of Audyssey equalization and room-correction technologies. Chief among these is Audyssey MultEQ, which corrects for time and frequency-response problems caused by room acoustics, and which calibrates speakers for audio balance throughout the listening space.

All three receivers have an iPhone/iPod-compatible front-side USB port that allows on-screen display of album art and navigation via the included remote. Other features shared by this trio include an analog RGB input for video content from a connected PC; PLL jitter-cleaning circuit technology; and Onkyo's new overlaid graphical OSD for adjustment of settings during a viewing session.

The TX-NR1008 and TX-NR808 include Onkyo's bi-directional and customizable preprogrammed remote control for programming all the components in the system.

The Onkyo TX-NR708 and TX-NR808 will be available at the beginning of July with suggested retail prices of $899 and $1,099 respectively. The TX-NR1008 will ship to dealers at the end of July and will have a suggested retail price of $1,399.
