I have the UMC-200 and on the calibration it does not recognize my rear speakers. I think the problem is the speakers since I used to have them on the front and it would not recognize them there - It says no speaker. It is fine for everything else. I went back in and manually added the rear speakers but I can't hear any sound from them - I can hear the test tones
I also notice that on the manual Eq settings there is no rear speaker
Is there a way to add my rear speaker? -- Do I need 7.1 program material?
