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.

    I have several Servo amps. I have found that a resistor located in the center of the input board often goes toast in the right channel. Fortunately, for my rig, I can swap in a left channel board from a spare. The resistor costs less than a buck at my local electronics supply house. Determine the correct value from the identical resistor found on the working side of the amp.

Samson SX1200 - Protect light on. No blown output transistors.

Have you checked the power supply section? Also look out for any IC's in the amp stages. They can go causing that kind of fault.

My speakers stopped working

Heating of the power transistor

can be one of the causes.

you may have to take out the complimentary pairs to check.

The pair may take out the drivers and some components along with it.

These may take some time, (troubleshooting)

But have a tech to guide you, if you need to DIY.

Good luck, let us know what you find or needs further assistance.

How do I connect my samson amp to my samson MDR10 mixer?

on the mixxer, use the "mix" "L" and "R" outputs. use 1/4 inch instrument cables, and connect the mox L and R to the amp's "channel 1" and "channel 2 inputs". always turn the mixing board on first, and the amp second- when turning off turn off the amp first, and turn off the mixer second. start with the mixer levels at the lowest, with the amp levels about 1/2 to 3/4 up. slowly raise the mixer channels first and then the mixer main volume until you have an adequate volume.

Hi, i have been suggested first a Samson servo 600, then a sx1200 is there a difference between the 2? is one better than the other?

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
