It's not the first mixer I've had to have this exact issue, I've tried a basic ground loop isolator, an iFi iDefender and plugging it in to other sockets/usb ports. The clip has the audio with just power/USB cable and no XLR and then with an XLR cable later in the clip. I've been trying to fix this for almost 2 weeks with no progress. 

That's it. After a decade of perfect service, it happened.

Really sorry for bringing this one back after several years. The BOOST button simply fell off.
Since there is no "parameter" to setup at this very one, unit still works great.

I remember years and years ago, people talking about this issue, but I REALLY can't find it anywhere. A TC forum, where I believe my salvation is, isn't working anymore. I also remember something about a "C" clip os something.
Please, any help would be great.

(Inside the button cavity, I can see the PC board and it seems there is a loose wire. Is it supposed to be attached to the button assembly?). 

Here’s what I have – almost all Behringer

• Eurorack Rack
• CM1A – MIDI to CV
• Brains
• 2600 Blue Marvin

I have a MIDI keyboard connected to MIDI IN on the CM1A

I have the CM1A CV OUT connected to V/OCT on Brains

I have tried connecting the OUT 1 and OUT 2 of Brains to various inputs on the 2600. Nothing seems to do what I want it to do, which is to basically run the waveforms of Brains through the VCF, VCA and outputs of the 2600 to my audio interface.

CM1A CV is configurable, but no options are familiar to me, since I am connecting to Brains, and not a System Whatever.

Unless mentioned above, no other connections have been made. Thanks in advance for any help anyone can give me.

Hallo mein GOXLR wird nicht erkannt wenn ich aber auf audio einstellungen gehe dann steht da das der treiber ein problem hat habe den jetzt mehrere mahle deinstaliert und wieder instaliert und immer noch der selbe fehler.

was kann man da machen das das funktioniert?

I get a load, high pitch squealing noise when I run the monitor signal from my JBL Eon One through any channel of my Behringer X18 mixer.  The monitor signal works fine through other analog mixers.  The squealing occurs with different power amps, different DIs and different cables.  I also get the squealing with the line-out from a Carvin bass amp.  Other line-outs work fine.  I have my my bus 6 signal routed to USB output for live streaming. 

We are a four piece acoustic band, and we use our PMP 2000 in Main/Monitor mode with passive speakers daisy chained.  No problem there.  For monitors we are using Kustom KPM4 powered monitors through the preamp outputs on the front.  I want to use an in-ear monitor, and I have a Behringer PM1, which I thought would work.  Unfortunately, nothing I have tried has produced any sound in the earpiece at all, including:

• preamp monitor out --> Instrument cable --> TS (F) to XLR (M) adapter --> PM1
• preamp monitor out --> Ultra DI --> PM1

Clearly I am missing something essential (and probably very basic) here.   Is the PM1 the culprit?  Would a P2 work using one of the above connection scenarios?  Is a separate headphone amplifier required?  I have to believe that others have faced (and solved) this problem.   Anyone willing to share a proven solution?

Need Help with external FX Routing -using AUX SENDS 1/2

I need help understanding and setting up my 2 external fx processors to this mixer so that I can use the aux 1/2 knobs to send vol to each channel. Im trying many diffrent routes and Im having trouble understanding the right way to do it on the QX1832. My original attempt is that I have it going from Send 1 and Send 2 jacks into my effect processors inputs. I then wanted to use the aux1 and aux 2 knobs on each channel strip to introduce the effect per channel. By the way I have the effect processors outs, unconventionally plugging into Ch 3/4 and 5/6 panned hard left and right (instead of using the returns) the reason for this is that I want to specifically route the effects sound through the mixer's sub outputs instead of main outputs - and this woudl be the only way to do it. part of my set up needs... So I can get the sound of effect 1 through send 1 but not for send 2. if I switch the cables of send 1 and 2 I can hear the other effect that wasn't sounding now sounding.. so essentially I cannot get to hear both send outputs at the same time layered or summed. the only way so far I have been able to get both to sound is by plugging in one effect to the send 1 and the second to mon out and using the mon fader to control fx2 volume.. it works, im not exactly sure what is happening in this set up.. would love to understand it a bit more.. but I would rather have both effects on send 1 and 2 working if possible.. im not sure if something is hardwired in a way where this is not possible and would love some help to get this set up correctly.

Thank you!
