Hi! I have an 720MX, running 1.4.095 firmware.

I just added a small external amp to power the rear speakers and am trying to use the powered rear outputs now for front height speakers using the RCA outs. So I'm going for a 7.2.0 configuration.

When I go through Genesis ARC, ALL the speakers work and are tested by ARC. But when I am watching TV the height speakers do not seem to be working. And when I go to the levels option in the SetupMenu and turn on the white noise , all the speakers sound except the Front Height speakers.

The height speakers were working before I added the rear amp via the RCA's. I tried going back to 5.2.0 setup and that didn't make a difference. Not sure why connecting something to the Rear Preamp out RCA's would make a difference though

Any suggestions? Thx!!!
