I facing a problem at which my amplifier trips without load. only one channel is tripping. it becomes very hot after i swicth it on for 20 mins and trips on high temp. this happens without any input singnal and output to speakers connected.
1200x with over heating output...does not care if it has a load unless it is too low,(Scott is wrong)..you have a leaky output, or a triac firing and clamping down the voltage to the speakers..the foldback shutdown may also be leaky, but these usually cause it blow fuses, and these get damaged by bad outputs or running the amp into shorts..since this amp has some really high voltages in it I suggest you take it to a shop before you KILL YOURSELF!
You need to have the outputs connected to a SPEAKER or Load
These amps DO NOT like no load conditions.
Hopefully the amp channel is still good after overheating
The Idle bias or channel offset circuit is not functioning and the longer you wait before you have it repaired by a pro, the more its gonna end up costing you. At this point its probably just a small bias diode or even an channel bias alighnment .Good Luck
power to the amplifier.
• The amplifier's Power switch is off.
• The amplifier is not plugged into the power receptacle.
• The amplifier's high-voltage power supply circuit breaker has tripped. Verify that the AC mains
voltage is correct, then press the Circuit Breaker button on the back panel.
Take it to the ER.
