One channel of my Samson SX 1800 does not work. It stopped working after a recent gig. Amp turns on, one channel works fine. Nothing comes out of second channel. No sound, no hum, nothing. What could be the problem?

Look at the circuit with a relay.

Did it suddenly stop working?
Maybe overload of amp or power supply.
I think you killed you power amp...

It sounds like the problem is just a bad soldering joint somewhere.

Either the channel on your radio is not working. Or the AV cord you are using is not working on one side (reverse the cord and plug it in the opposite you are using now. If it still only works on the one side your cord is good.) Or the final transistor for the channel on that amp might have blown. You could also have a cold soldier joint on or otherwise faulty jack plug. Let me know if this helps you find the issue.

the servo series is geared more towards studio applications and/or installs, while the sx series are geared for live pa applications. the servo 600 is 300 watts per channel @ 4 ohm, and the sx1200 is 450 watts per channel at 4 ohms. the sx amp can also be bridged over to mono mode, where it puts out, i think, 1100 watts mono.

the only variable i havent been able to cover is sound quality, and im not seeing those listings in the specs on the samson website

dont change the drive change the laser dhe drives are coded to each ps3 if that dosent work just change the hard drive whit the one that works

Sounds like an output going bad. Try to get some electronic contact cleaner and spraying on the circuit board. If its corroded this will help clean the circuit..

Check all connections completely.

check see if youy have some coving the vent or the speak connect right
