Here is a photo of the entire rear connection panel of the Onkyo TX-NR708. As you can see, the Audio and Video input and output connections are located on the along most of the rear panel area. Also
In addition, unlike most manufacturers, who cluster their speaker connections in on area, Onkyo has chosen, what I think is, a very practical arrangement for speaker connections, running across the bottom of the rear panel.

This makes the connections easier to identify, and also gives the user more space to insert bare wire connections. I wish all home theater receivers would adopt this type of speaker connection layout.

For a close up look and explanation of each type of connection, proceed to the next three photos in this gallery...
