20 Most Recent Behringer EURORACK UB2442FX PRO Mixer Questions & Answers

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.

Hi, did you find a solution for this problem? I have it too.

VIa, XLR, TRS, 1/4 Jack, phono,,

Sounds like a dead spot at the centre position i.e. the wiper of the pot not contacting the track at that position. Try some contact cleaner / lubricant & whizz it back & forth a good few times, take it in for repair/replacement of the pot or leave it just off centre or use a different channel :-') Good Luck!

It Depends how many Channels you are wanting for a basic 2 deck set up using Cdj's you would want 4 channel 2 per deck 1 master out and 1 booth so you can hear it through your head phones but if you were doing Karaoke you would want 6 channels for 2 microphones all going 2 the master out. but it changes again if us software and controller because most software has an internal and external mix mode. Here is a video that might help

This place has a great selection of Behringer parts. You should be able to find your knob here: http://www.dbmproaudio.com/behrparts.html

Check the type of microphones connected and set the proper settings,and connect it to other mic inputs .

The outputs of these mixer needs to be connected to an active speaker.An active speaker have an amplifier and a preamplifier.

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.

The VR96 is a 50K "G" taper or "graphic taper" pot. Lots of luck trying to find that in a catalog... I finally got a scrapped piece of mixer board and salvaged one. The G taper is not stocked by any of the vendors like Digikey or Mouser here. Full Compass is the Behringer part distributor and I waited 6 months and got no delivery of one of these pots. The effects selector is a rotary encoder quadrature type. Use the Mouser.com catalog. Search for Encoder, then select ALPS manufacturer and then try to match up mounting and type using the spec drawings... with push switch also... Again, if you want to try Full Compass, you can call Behringer rep in Woodinville WA USA to get the Behringer part number and incident number to see if Full Compass might have one in stock.

Here is the maintenance schematics for your unit...VR96 is on page 7 of 32. :

Scroll down to "get manual" and click on it to download. IGNORE other download links as they are for viewers, etc.

Note, You may have to cut off a shaft on replacement to the right length to match existing shaft.

You can use the compressor in two ways. 1st you can go inline from the main outputs into the compressor out of the compressor to the rest of the world using normal cables. You may also insert the compressor into the main inserts using a cable that is tip, ring, sleeve 1/4", to seperate 1/4" tip sleeve mono plugs. any more questions give us a call at the store 215-736-8055

If more than one input is bad, then problem has NOTHING to do with the preamps. Check list:
1. Make sure you are using BALANCED lines everywhere... either XLR or TRS cables.

2. Make sure ALL interconnected equipment, mixers, amps, powered speakers, CD players, etc. are ALL powered from the SAME receptacle or power distribution unit.

3. Do proper setup. Select each channel PFL and set the trims so the indicator never goes into clipping, but is in the 70% range during max volume input to mics, etc..

4. During operation the sliders should be at least 50% up on used channels and the mains. Setting of levels throughout the system is important for noise free operation. Using EXCESS gain at some point results in distortion and noise. Using sliders near the bottom position results in poor signal to noise ratio.

Now re-read #2 above... and believe it. I have seen a lot of equipment blown due to ground bounce of building power. That is why the pro's run power back to their mixer from the area where the amps are powered.
