Behringer POWERED MIXER, 20 CH, 400 WTS AMPLIFIER => Model PMX5000 Car Audio Amplifier Questions & Answers
My powered mixer Behringer is buzzing
Make sure the buzz doesn't happen because of feedback of speakers into mics. When feedback is processed it often goes to a buzz instead of the usual howl.
Also check that you are running adequate inout into the effect since a very low inout will incur digitizing noise and loss of signal=to-noise ratio.

My behringer powermixer is making a clicking
You have blown the power amps in the unit. This is why you must insure that the speaker leads cannot be unplugged while unit is powered.
I don't know what model mixer you have, but ones like PMP3000, PMP5000, PMP1280S use a switching class D amp that arcs through a circuit board.
One can get a replacement:

I have NOT done business with this company before but you need to see if the HCA2400 module is what you have in your unit. Note that it has covers on the unit pictured at the site when installed.
I have repaired these, but it is an extensive process including carving out burned board material and replacing many components.

BEHRINGER EUROPOWER pmx 1000
The voice cancellor switch basically subtracts the left and right signal because the vocalist is usually centered... The noise would likely be in an op amp associated with this feature...
Compare your circuit to a PMH1000. On that unit first thing to check is the two electrolytic caps at the left and right noise cancellor outputs.
There are a wholle bunch of resistors and IC's 48,50,37 are all involved.
Troubleshoot this one with freeze mist (ccircuit cooler). The problem should show up easily by heating and cooling.

Behringer pmh mixer manual
Are there lights or effects windows lit up? If so, the power supply is likely OK.
If neither speaker is working, that is bad however make sure all your trims and sliders are right to send audio through. Some have a standby switch.
This probably has an HCA2400 amp board in it and those can burn up for various reasons including loose speaker cables.

Unit will not power on, no light,no sound no
Hi, since you are sure that the fuse is in good condition, then the problem lies in the board panel. I will advise you to take it to a technician to read the board with a meter properly so as to detect where the fault lies...maybe,one of the I.C diode is bad and needs to be changed.
Take care

New behringer powered mixer, comes on, but doesn't hear anything.
Fan comes on with temperature rise. Not a problem if off till you start driving speakers loud.
Make sure standby switch is up. The slide switch is up to A/B.
The main fader iis up. Your input fader(s) are up. The trim controls are up enough. Inputs are plugged to input and not the inserts.
Be careful... this unit has a lot of power and can blow speakers.

Behringer pmx 2000 missing knob
If the shaft broke, then you will have to replace the whole encoder for it. You cannot glue a shaft and expect it to hold.

Behringer inboard effects modul board
BEFORE you throw away the board, I found a similar board in a different unit that had a SIMPLE problem. Check if your board has its own built in 5 volt power rectifier and regulator. The bad one I had required ONLY changing the DC filter electrolytic cap that, for my estimation, is undersized capacity wise.

BEHRINGER PMH1000 POWER MIXER FAULT - TRIPS HOUSE ELECTRICS
THIS MAY BE NORMAL. The starting transients can trip RCD's or GFCI's as we know them due to high frequency components that are not balanced due to capacitive coupling. IF you have the inputs connected to OTHER devices such as effects modules that also have line power to them there may be a ground loop.
ALWAYS connect any interconnected device to the same power source for equipment safety. Behringer is stingy on schematics.
You MIGHT try using a decent line filter to supply the unit. It has been a while since I repaired my 1000, but I don't recall any specific thing in the design to unbalance the current, HOWEVER the power does go through a thermal switch on the heat sink for the power transistors and the wiring CAN be dressed so that it might couple to the other internal wiring AND the safety ground. Suggest you try a small lamp in series with the safety ground (third wire) to see if you get any appreciable current there during startup. Make an adapter... DO NOT cut into your power cable to do this.
