20 Most Recent Mackie ProFX12 Professional Compact Mixer Questions & Answers


It sounds like a part is burning out. If you can look inside , look for a part turning brown or getting really hot in that area. That would be the easiest thing to do if you can get in there.

Be sure the capacitor was replaced with the correct polarity?
in the beginning of my tech career I have replaced caps back words on accident. ..

Maybe an open ground somewhere or something needs shielded.

Use balanced lines for the audio interconnects. Use XLR low noise mic cables or TRS type cables. IMPORTANT: Power the speakers and the mixer from the SAME receptacle, even if it means running extension cords. Ground bounce in building wiring can destroy the circuits in the equipment.

it should be if you hook something up to an input channel like w the band i was in i had to hook my turntables up to a microphone jack on an open channel . so yeah if u plug lets say a cd player plug the output of that into the input of the mackie and make sure you have your speakers in the output of mackie all set up and it should work no problem. We have the same mackie

This is probably pilot error. There are a bunch of things to do to setup this correctely. I would recommend looking at the videos about mixer setup on YouTube. There is a procedure you go through that is COMMON to most brands of the mixer. The fact that the volume meters aren't working at all implies a problem that the mixing buss is not receiving audio. Turn trim gains up, turn the faders both the channel and the main up, and UNMUTE the channels of interest and you should be getting audio through the unit. ALso does your headphone jack work?

You probably have issues with caps in the power supply....I would check that first...open it up and look for buldging caps and replace any that you find....
