Just bought the Denon a10SE in the AV classified section. I'm having trouble getting sound from my rear speakers. Ive already talked to the guy that sold me it and he's been extremely helpful and gave me a lot of time last night. He also assures me the amp works fine. I'm sure I have it setup correctly but I cant get any sound from my rear speakers. I have it setup for 5.1 When I use the test tones, the front L&R are fine, the Center is fine, but the Rear L&R I'm getting nothing. Last night when I first set it up I was getting sound from the Rear L...I then took the wires off and reconnected the rears again and now I get nothing from either of them. Ive connected them 1 at a time and swapped the wires, still nothing. I'm using bi-wire speaker cable and bare wire, I dont use banana clips or anything. Could someone help me please ? Thanks in advance.
