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.

Speaker humms only. what causes that?


Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

65a Resolv studio monitors. The left one just blew out -- maybe. The blue LED stays dim, as though the monitor has been sleeping. When I power off the monitor, the speaker gives a loud pop, and the cone...


You are getting DC offset voltage on one of your amplifiers that is the reason the speaker pushes out and you might be hearing a humming noise too. Do not turn on the speakers till you get it fixed or else you would end up burning the speaker voice coil too.The dim blue LED is also an indication of a short circuit in the output stage.
Your left amplifier needs a output chip (IC ) replacement. You will need professional help to do that. Will cost you about 20$ plus service charges.

Check only one active speaker at the mixer output and report the results.
Connect only one of the audio inputs from the power amp at the mixer output (and the passive speakers at the output) and report the results.
Sometimes (in parallel connections) there are interferences from the volume controls.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Hum coming from one speaker


Not good. you may have a blown amplifier. To check this, put a volt meter across the speaker terminals with the amp hooked up and off. Turn the amp on with the volume set to minimum and check for any voltage at the speakers. you should have no DC voltage (less than .1 volt) at the speakers. hope this helps
