 1.4a inputs, the TX-NR708 offers copious connection possibilities, as well as 3D video compatibility. For your convenience, one of 
the HDMI inputs is located on the front panel, along with a USB input for flash memory devices and iPod models. If you want to connect 
a non-HDMI multichannel component—say, a legacy SACD or DVD player—the TX-NR708 sports a full complement of 7.1-channel 
analog inputs. The Onkyo name connotes serious audio quality, so it’s no surprise to find low-jitter Burr-Brown DACs and sophisticated

 1.4a Support for 3D Video and Audio Return 
Channel
 
The seven HDMI 1.4a inputs on the TX-NR708 let you simultaneously 
connect high-def sources such as a Blu-ray player, a gaming console, 
and a cable/satellite tuner. A single output then sends a pristine signal 
to your connected high-resolution display. 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 entering the market. The TX-NR708 
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 your A/V receiver, without the need for a separate S/
PDIF audio cable.

 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-NR708 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-NR708 brings to life a huge array of internet radio channels 
from Last.fm 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-NR708 connected 
to the internet is that you can then easily update its firmware. 
*Availability of services depends on region.

 IIz Add New 
Dimensions to Surround Sound 
The TX-NR708 handles two new surround-sound technologies 
from Audyssey and Dolby that offer exciting new ways to set up 
the speakers in your home cinema system. Audyssey DSX lets you 
incorporate “front wide” speakers, in place of the usual surround 
back speakers, to expand the width of the soundstage. Set up at 
a recommended 60° off center, these channels help to produce a 
more realistic soundstage and a more immersive listening experience. 
Alternatively, Audyssey DSX can reconfigure the TX-NR708’s surround 
back channels to deliver “front height” channels. These channels carry 
ambient, non-directional audio that adds a new vertical dimension to 
your movies and games. Dolby Pro Logic IIz provides a similar front-
height speaker option that likewise works to create a more enveloping 
home cinema experience.

 Certified
THX Select2 Plus certification is specified for rooms where the screen-
to-seat viewing distance is 3 to 4 meters and the room volume is 
around 56 cubic meters. To achieve THX Select2 Plus certification, 
the TX-NR708 had to meet the world’s most demanding standards 
for home cinema audio quality and performance, and play at reference 
volume levels with minimal distortion.
