Those two 390 Ohm power resistors are the bane of this equipment. They are part of some shady design choice by Behringer, which kills the equipment by overheating. Users should always keep the FBQ function on, to keep thermal dissipation at a manageable level. When you shut off the FBQ thing, all the fader LEDs should light up to max. Those resistors supply the fader LEDs, passing enough current to cook themselves and their surroundings when FBQ is off. All the electrolytics close to these resistors dry up and die soon and it's common to find one of the regulators dead too, certainly because of the prolonged overheating caused by the additional power dissipation inside of the entirely sealed enclosure.

Hello, I also have a problem with the top lane. Not a lot of sound and saturation .. I have redone the power supply but have not yet changed the capacitors on the front plate.. Do you think this is the solution? Thanks a lot

Suddenly got the 250Hz lighting up constantly and no audio signal going thru. Disengaged Audio In then still works as a bypass. Any tips? I probably should just find alternative solutions haha too old of a system.

I have a different problem: although channel 1 and 2 get the same input level, only half of it is output at channel 2 (compared to channel 1). Does anyone have a similar problem or tips to fix this? Thx
It's just a great EQ. The Behringer FBQ3102
