Zone 2 Option

The TX-NR708 allows for connection and operation of a 2nd Zone. This allows a second source signal to speakers or a separate audio system in another location. This is not the same as just connecting additional speakers and placing them in another room.

The Zone 2 function allows control of either the same, or separate, source than the one being listened to in the main room, in another location. For example, the user can be watching a Blu-ray Disc or DVD movie with surround sound in the main room, while someone else can listen to a CD Player in another room, at the same time. Both the Blu-ray Disc or DVD player and CD player are connected to the same Receiver, but are accessed and controlled separately using the same main Receiver.

3D Compatibility

The Onkyo TX-NR708 is 3D Compatible. This receiver will HDMI will detect 3D source signals automatically and pass them through to a 3D-enabled TV without further processing.

Audio Return Channel

What this function allows, if the TV is also HDMI 1.4-enabled. is that you can transfer audio from the TV back to the TX-NR708 and listen to your TV's audio through your home theater audio system instead of the TV's speakers without having to connect a second cable between the TV and home theater system.

For example, if you receive your TV signals over the air, the audio from those signals goes directly to your TV. Ordinarily to get the audio from those signals to your Home Theater receiver, you would have to connect an extra cable from the TV to the home theater receiver for this purpose. However, with audio return channel, you can simply take advantage of the cable you already have connected between the TV and the home theater receiver to transfer audio in both directions.

should explain networking more, Member pxgard

The review is good, but one of the great features of this receiver is the network control. Also, I found the setup very straightforward, and skipped the manual. I found the on-screen setup very intuitive. I use the OnkoTron iPhone app, which is great for controlling it over the network instead of using IR.
