I own an Adcom GFA-7000 5 channel amp which includes LED's for Thermal Protection. If I understand correctly, these LED's are only supposed to light when any individual channel overheats; the amplifier's thermal-protection circuit shuts down and a red LED on the front panel will light up until the temperature drops to a safe level; the others channels continue to operate normally. In my case, my LED on only my Left Rear Channel comes on when I power up the amp and stays on as long as I run it. It is not even warm, much less overheating, and I listen only at moderate listening levels. I disconnected all other channels and can still hear sound coming from the channel in question. In fact, it matches the sound output on the Right Rear Channel. I contacted Adcom directly and they told me that they never heard of this happening before and that I should not hear sound from that channel when the LED is lit. Can anyone explain this? Do I have a defective LED (low concern) or is my amp in need of technical assistance (high concern)?? Adcom would only tell me I needed to have a tech look at it, or trade it in for a new one. I don't want to jump the gun for just a little red light. Any advice would be appreciated.

Hello all,

I found a buzz/hiss problem with the 1095... -
My father was using an Adcom GFA 7000. He wanted to connect a sixth speaker to the 5 channel amp and thought he would try some crafty wiring. He took the speaker cable from the sixth speaker and split it four ways, connecting a pair to both left surround and right surround channels (thinking he would... -

Okay, I am looking at some amps for my subwoofer. I am using four 15" Avalanche drivers in a large box system. That is another forum. It has been recommended that I use Behringers's EP2500 amplifier, which I am happy to do, but wanted to compare some others and learn something at the same time....

Hi everyone,
I have two questions about newly purchased 1068 and 1075 for my HT system.
1. When I turn off the 1075 amp, the red LED turns off. Then, all 5 protection fault lights come on at the same time for a second, then shut down in unison. Is this normal? I could not...
