Re: Behringer Eurorack UB2442FX-PRO Bad Capacitors
One thing I forgot to mention in my post above. The Panasonic replacements for C12 and C16 (1000 uF/25v) are 30mm tall but the original Xunda caps were 20mm. This is significant in this case. I had to modify the power supply case and even so there was a slight interference between the case and the main board of the mixer. Since I didn't know the original specs of the Xunda caps I trusted the wisdom of the group and bought these panasonic caps but if you can find shorter ones it would be wise.Comment

Re: Behringer Eurorack UB2442FX-PRO Bad Capacitors
Friends have a BEHRINGER mixing console EURORACK UB2442FX-PRO, which is a number of problems, I have no great esperiência in the repair of such devices,
1 only has signal input on channel 1 and channel 4, the other gives nothing.
2 in the signal input to the tape, just enter sign on the right channel.
3 only has signal output on the right.
I would appreciate someone can help me on this repair.Comment

Re: Behringer Eurorack UB2442FX-PRO Bad Capacitors
Not trying to resurrect an old thread but I have the same mixer and i replaced all the caps thinking that would fix my problem then come to find out one of the resistors is burnt. Is there anybody with a good working powersupply that can take some pictures of the resistors and post on here... i can't find a place that shows what was supposed to be there and since it is burnt I can't read the bands. Thanks!!!

Re: Behringer Eurorack UB2442FX-PRO Bad Capacitors
Can we see straight shot, high resolution pictures, please?
The service manual has all the schematics "but" the PSU off course.
I've dug up this one on my computer, but google something like "Behringer UB SMPS .pdf or PSU and google will be gladly return more schematics, even when you click on pictures.Last edited by CapLeaker; 08-08-2016, 06:20 PM.Comment

I have that UB2442FX-PRO mixer, no repair done, and not been used long time. I can look inside it, if it helps someone. However, please provide a picture and good explanation, what should be looked at.Comment

Hi, I got Behringer Xenyx 1204USB mixer, and in the morning mixer was working fine, but when I came home from bike ride I turn it On but nothing happend. Phantom switch is working because red light is On, but other switch no respond.
I brought mixer to my friend today who is electronic expert and he will tell me if it's the button or something on power supply that died. But I am 90% sure that it's power button. My question is, is it possible to put some better quality switches on that mixer than the ones mixer came with, I found them very cheap and low quality. -
Hi, I have few questions
1. few of my pots on mixer are turning so hard, I tried to clean them and spray some DeoxIT Fader spray in it, but it didn't help. Is there any way to put some grease inside that pots whole that is on the side instead of spraing in it ?
2. Or is it just simpler to replace them all with same ones ? I am not into pots, so am I able to put some better quality ones or it needs to be same one as they were default ?... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :

switching supply area).

than 6.3 V.)

I replaced capacitors with aluminum-polymer.

Hi guys
I have this faulty mixer here. Basically the owner says it worked fine at one gig, then the next one it didn't
When I power on, both the L & R LED Meters go to +4 and stay there. This is without any input and with all sliders Level Set knobs set to zero
Also the LED meter on the 24-bit dual engine DSP goes to red (clip)
I didn't connect an speakers but if I use headphones I can hear what I can best describe as a purring noise on both channels
I found a schematic for the PSU There is a 10 way ribbon cable going from the PA/PSU... -
Hello dear audio friends.
I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
Thanks in advance if anyone can help me with this schematic.
Of course, all information about this digital mixer and possibly references...07-24-2023, 06:40 AM
