Behringer XENYX 2442FX Mixer - Answered Questions & Fixed issues
Hello!
I have a
Often teh power supply fails because of other problems. Unless the board has flame damage the parts that are defective can be replaced... Getting some of the parts that are special can take time. Most of the components are available at many sources however. The SPS400 power supply can be repaired.
Here is link to schematic that should have the SPS400 as well as the rest of the PMH1000 on it.

My Behringer XENYX 2442FX Mixer does not power up,
You should find +/-15 volts and +5 volts as well as the phantom power... but that light can come on at much lower than desired voltage.
Note that the regulators are current limited so a short on the mixer board can kill one of the voltages.... but you are not getting any input from teh switching portion of the regulator so the switching part of the supply is apparently dead. To replace the supply you would have to call Behringer at 1-425-672-0816 to get the part number and an incident number and then call FullCompass which is their part distributor now.
When working on a switching power supply, use an isolation transformer for safety and use a 60 watt lamp in series with the power cord to limit current during testing.
The circuitry will be SIMILAR to the power supply found on page 9 of schematic you can download at:

Flashing lights
Were you able to get this fixed? I've been having the same issues and the Fishman support team's instructions for cleaning the pots didn't fix it.
Mixer Switch on and after a short period theres a noise that sound like a machinegun and a Hiss sound through the speakers
I assume that the power-amp is good.
This noise, of course due to defective parts inside.
But, which section is it? Chances are:
- Amplifier circuit in the Main-Outputs. If the MAIN MIX in the minimum position and still noisy, then the damage in that section.
- At one or several channels. Let's test.
Set to minimum volume for all channels and MAIN MIX. EQ=flat. FX=minimum. TRIM at half (let's try at 12 o'clock).
Raise the MAIN MIX, let's say at 15.
Gently, raise channel 1 volume to maximum, listen, if there is no noise, channel 1 is safe. Lower the volume to the minimum again. Move to another channel in the same way.
If found noise, that is where the problem is.
Actually, many more detailed steps for testing, but the description is too long. This above is a simple way.
Circuit power supply should also be checked, whether all normal voltage.
It is part of the image of the amplifier section circuit.
Parts which may be broken is the IC 64,65,77.
How to set onboard fx processor
Which clip light on what and what mics are you using?
The small room settings are from 10 so just turn the know to the setting you require and press it, this should set it.
The stadard way of setting up mics is to set the channel gain so the channel clip light just blinks occasionally when you are making the maximum sound you can into the mic.
For effects repeat this process using the aux send FX for each channel you want fx on (turn the rest to 0) and doing a balancing act between these and the aux send fx master so you can only just get the FX clip light blinking occasionally.
Next set your gain/attenuators on the amp(s) so its clip warning can just trigger when you are giving it 0db when you are playing the loudest you ever will.
A mic fading away could be the battery dying (in which case try using phantom power) or if they're radio replace the batteries before each service. If they're wired dynamic mics then it is possible there's some protection circuit somewhere that's reacting to the constant clipping and backing off the amp.
RESET ON BOARD FX
The clip light means your input signal is too high and distorting. Turn down the attenuator(input) knob until it goes out, use the channel volume for level. It should have a knob for the names of the effect selection.
I can't hear the sound from my PC when I'm using the mixer. Its hooked up to both the computer and the speakers, but when I'm recording in pro-tools 11 I can't hear any of my playback. I have to bounc
hello. Im not too familiar with Protools (mainly because its a headache right out of the box), but MY understanding is that Protools won't recognize a lot of external audio devices. (such as behringer)
however..if you are able to record and 'see' the audio there, just not hear it, there might still be a solution, & seeing as how i never used protools, it still might just work.
First of all:
if you're using the UCA-200 external usb box connected with rca cables, then my solution SHOULD work, as it is what i did to get mine to finally do the same thing.
#1) you will need to pick up (x2) RCA-1/4 jack adapters . (radioshack, about $2 each)
#2) insert a red and white rca cable in the RIGHT side of the Mixer's CD/Tape out .....the other end of the rca cables will go into the UCA-200 INPUT.
#3) with 2 more cables in the OUTPUTs of the UCA-200, put the rca-1/4 jack adapters on both cables, insert them back into the Mixer inputs 9/10 (in the analog 1/4 instrument inputs)
#4) adjust volumes accordingly, make sure channel 9/10 isn't muted, headphone volume is up, etc..
.......if that didn't do the trick, then you will need to go into the Audio Settings menu on your computer..(or protools) and change the default playback device to your mixer (probably named Generic USB or something similar)
I really hope this helps somewhat, because i remember going through the same thing & it took a looong time to find the correct awnser.
best of luck!
*also*
check for any updated drivers for your mixer! (I personally recommend you do a Google search for Asio4all drivers, they're pretty good)
if your awnser is A), i would suggest going into your computer's Audio Settings menu, and select the mixer as your default playback device.
Channel 1 makes a pulseating click and NO sound
Hello,Operational amplifier circuit named 4580 is the issue as with most of mixing boards, each channel has its own operational ic's and one way to know which one is defective is simply touch every one on the board, inside of course, of the non-working channel, check for excessive heat and if you find one pretty hot compared to other you just find your bad component, you will recognize what type of ic im talking about, is a 8-pin smd ic where the pin 4 should have -15v and pin8 should have +15V, no other pin should have any voltage and this is another way to test an opamp, with a dmm in dc volts referenced to ground, chassis ground, let me know if you need further assistance.
Run an active subwoofer with a Xenyx 2442fx
Probably the easiest way is to run a balanced 1/4" TRS to XLR Male Interconnect Cable from one of the AUX outputs from your 2442 board. Here's a link to an example cable: http://www.sweetwater.com/store/detail/BPBQXM20/Good luck! :)
I cant find the echo part on the mixer for karaoke
The effects or FX section is on the top right of the mixer. On your vocal channels find the yellow knob marked FX and turn it to 0. Choose the effect you need using the Program knob (top right) for karaoke this will probably be 03 or 06. Start singing and turn up the yellow knob marked 3 - FX under AUX Sends until the LEDs above them hit -0db, no higher.Now find the button marked FX - Main Mix and make sure it is UP.Turn up the yellow knob (3 - FX) next to it until you can hear enough echo on your mic.
