Since you'll be using your 772 to set the crossovers, which apply to both the speakers and the sub(probably 80Hz would be best), you turn the control on the 175 all the way up to the 120Hz max to get it as far away as possible from the 80Hz crossover that the 772 is doing, so it doesn't interfere.

All HT receivers are a bit complicated, but relax and take your time; it'll work out. If you have any specific questions in the future, ask of course.

Seeing your last post, if you have an HDMI cable, you can use it for both audio and video output from the Oppo.
