It is quite possible that you have bought a set that has a faulty preamplifier. The equaliser needs many such mixing preampflifer IC's mostly coupled together and it could be that there is a failure in one or several of the channels, the stages of the preamplifier. You must use a signal test to identify the faulty stage. You will need some help to go through these circuits and identify the op amps that are faulty. Try to check for voltage on the op amp stages and test with an audio signal for the section in fault. Hope you try. Good day.

Behringer mixer Eurorack UB802 is losing partial stereo signal in one channel. When I record (audacity software) I can hear both channels but displays one channel. Is it my computer's audio jack t


Sounds like the output cable from the 802 is not correctly pinned to your input on the computer. Fred is on the right track but you may need to take it a bit further.
It may also be helpful to use a Pro USB audio interface such as the Digigram UAX220v2 (line level version).
If you wish to use the computer's on board sound card consider an IHF/Pro interface that converts balanced audio to unbalanced , and the proper cables. Two 3-wire balanced 1/4-inch from the 802 to the left and right inputs of the interface (XLR Male), then RCA (Red and White) to a 1/8-inch TRS Plug cable onto the the computers audio input.
Henry Engineering's Matchbox HD comes to mind.
Good Luck.

Only the left channel on the whole board works. Is there some part that might be replaced to fix the right channel?


First analysis needs to be done to isolate what can be discovwered before opening the unit. Does the sound appear in BOTH sides of the headphones? There are MANY components that can kill the right side including cracked circuit board. Beyond a certain point one would use an oscilloscope to troubleshoot.

When i have my FX on and sending to main they make a horrible clicking (shorting out) sound. if I push the main mix button it shuts off the effects and the noise goes away...bad side...then I have no...


Check the 5 volts to the FX unit, If the voltage is low, the FX processor will keep reseting generating clicks, In a different product, the 5 volt filter cap was degraded and voltage dipped down to 4.5 volts causing resets.

I have a Behringer UB2222FX-Pro Mixer. The effects control knob (turn/push) has broken below the face of the mixer. Can this part be replaced and where can I get it? Thanks


You need to find a pro audio repair shop to have that repaired. OR you can send it in to Behringer. To my knowledge parts are not available to just buy for them. You'll find that the switch you're ref. to, is soldered to circuit board.

LEVEL POT ON A BEHRINGER EURORACK MX 602A-BAD


It appears that both these use a 50K pot in the identical circuit and it is UNLIKELY they re-engineered very much so it is likely they use the same pot.

Behringer parts service should be able to tell you.

Left channel out on behinger ub2222fx-pro could use a service manual. Thanks in advance


Behringer only give the manuals to their authorized service agencies I am told.

Mixers are very symetrical and have lots of diagnostic capability from the outputs.

If you headphones work, chances are the moxer biss es are OK which probably focuses the problem on the output drivers.

Use headphones to see what jacks work... Remember that a stereo headphone will only have sound on one side for the mono jacks you test.

If your mains have a dedicated slider, one half of the slider could be bad. Usually you can tell those by a rougness as you slide them.
