PS-400 Signal Presence LED Stuck On

Recommended Posts

The green signal presence LED for Channel 2, which used to blink on and off in rhythm with the input level, is now always on. The LED for Channel 1 is functioning as normal. I am using the amp in Bridged Mono with an 8 ohm load. (subwoofer)

The amp seems to be functioning normally. I switched to Stereo Mode and tested each channel independently and everything sounds fine. Even in Stereo Mode though, the Green Signal Presence LED for Channel 2 remained lit constantly no matter which channel was in use and no matter what level of input the amp was presented with.

Please help....this is driving me crazy. I love this amp and I want it to work correctly.
