HDMI™ 1.4a Support for 3D Video and Audio Return Channel

The eight HDMI 1.4a inputs on the TX-NR3008 let you simultaneously connect high-def sources such as a Blu-ray player, a gaming console, and a cable/satellite tuner. And the two HDMI outputs let you send a pristine signal at the same time to two different high-resolution displays. As the latest version of this connector, HDMI 1.4a adds the exciting possibilities of 3D video and an Audio Return Channel. 3D video is the next big thing in home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible TVs coming to market. The TX-NR3008 also offers the convenience of an Audio Return Channel via HDMI. Audio content received directly by your HDTV’s tuner can be sent “upstream” to you’re A/V receiver, without the need for a separate S/PDIF audio cable.

PC Audio and Internet Radio via Network Function with DLNA 1.5 and Windows™ 7 Compatibility

As one of Onkyo’s new breed of receivers that can link directly to the internet or to your home PC via a local network, the TX-NR3008 takes streaming audio and internet radio to a whole new level. MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, and LPCM audio files—whether on your PC or from the internet—can now be played back through your main system with unprecedented power and fidelity. The TX-NR3008 brings to life a huge array of internet radio channels from and vTuner*.  As well as being compatible with earlier platforms, the receiver is compatible with Microsoft’s new Windows 7 platform, which includes the DLNA 1.5-specified “Play To” media-streaming feature. Another benefit of having the TX-NR3008 connected to the internet is that you can then easily update its firmware.
*Availability of services depends on region.

THX™ Ultra2 Plus™ Certified

The ultimate benchmark for home audio performance, THX Ultra2 Plus is specified for rooms where the screen-to-seat viewing distance is more than 4 meters and the room volume is 85 cubic meters or greater. To achieve THX Ultra2 Plus certification, the TX-NR3008 must meet the world’s most demanding standards for home cinema audio quality and performance, and must play at reference volume levels with minimal distortion.

Advanced Video Processing and 1080p Upscaling with HQV Reon-VX

HQV Reon-VX is the most sophisticated video-processing chip available for home cinema. It provides the ultimate support for 1080p scaling; for filtering of jaggies and artifacts; and for the reduction of random, “mosquito”, and block (codec) noise. HQV Reon-VX also enables color region enhancement and the rendering of more than one billion colors.

VLSC™ (Vector Linear Shaping Circuitry)

Onkyo’s VLSC employs a unique digital-to-analog conversion circuit to mitigate the effects of signal noise. Data is converted between discrete sampling points, which are then joined with analog vectors in real-time to produce a continuous output wave form. The result—a noiseless, smooth analog signal based on the digital source.

Harnessing Power for Audio Performance

Onkyo‘s H.C.P.S. (High Current Power Supply) concept is based around power transformers with the capability to respond to the wide dynamics of home cinema. In the case of the TX-NR3008, a massive main transformer improves power efficiency and radiates very little noise into the surrounding circuitry, while two separate transformers cater specifically to audio and video processing. The TX-NR3008 also employs large, custom-designed transistors to drive the high currents that today’s home entertainment demands.

Tailor Multichannel Audio to Your Home with Audyssey and Dolby Technologies

The TX-NR3008 is equipped with MultEQ™ XT32, Audyssey’s most powerful room-correction technology. MultEQ XT32 gathers frequency and time-domain measurements from up to 8 positions in the listening area, to deliver a clear, well-balanced, and natural sound. Two other Audyssey technologies, Dynamic EQ™ and Dynamic Volume™, work to optimize frequency response and dynamic range at all volume levels. In a similar vein, Dolby™ Volume performs independent loudness adjustments to different frequencies and channels to produce a listening experience that includes all the dynamics of the original mix at whatever volume you choose. It also offers the option of maintaining playback volume at the same user-chosen level across all input sources.
