SOURCE: I have a Behringer PMP

There are NO "yellow" overload LED's period. The clip or overload RED LED's are just above the PFL buttons for selecting a solo channel. There are "yellow" signal received lights (level set) up near the trim controls. In normal operation these will light when signal is received. Here is schematic for the PMP5000 which is really identical for the 6000.
http://elektrotanya.com/behringer_europower-p0569_hca2400_sps1000_dpx_pmp-1280s_5000_sch.pdf/download.html This has part of the DSP and PS and the PA circuits.
Scroll down to "get manual" and click on it to download. Ignore other download links on the page.
Try turning off the Phantom power if it might be on... If that stops the hum, something is the matter with the bypasses feeding Phantom power to those channels... Possible problem might be shorting of one of the coupling caps at the preamp input. The PMH5000 drawings are more accurate at the input circuits. You will note that the level set LED's are the yellows, and the clip/PFL LED's are the red ones. I suspect that RF bypass caps such as C110 or C121 (example typical for channel one) might be shorted. This makes noise on the Phantom power line unbalanced and will get into the channel where one of these caps is shorted. Do a test: Plug a shorting jack that shorts the tip to the sleeve intot he inssert for the channel. With the LOW CUT button up, observe is the level set LED for that channel dims or goes out. If it does, then I supect you have a shorted RF bypass cap at the input..The next test involves driving a KNOWN balanced signal into the XLR jack and using a TRS in tthe inout 1/4 inch, test the levels with an oscilloscope to verify the hot and the return have equal amplitudes. I they don't, congratualtions you have to tear the main board out... lots of knobs and screws to access the inout circuits and verifuy the cause... it could ALSO be a bad transistor in the inout pair, etc...

Where do you have the gain control set on the Mic channel ?
If you have no issues with either the speakers or the Mic, and the gain control for the channel you have the Mic plugged into is set at a somewhat "normal" position, you might have a problem with the mixer itself.

Changing channels by it self


Is this happening only with the foot switch plugged in? A bad cable on the footswitch is the most likely cause but there could also be a problem within the footswitch jack on the amp.

Foot switch appears to be wired backwards. The Shape pedal turns on the UtraBass and the UltraBass pedal turns on the Shape (Channel 2).


Foot pedals are usually NOT interchangeable... The correct footswitch would come with the amp so be sure it says Behringer on on the footswitch. Apparently some sellers have foisted off VOX footswitches which may not work with the Berhinger.

I have just bought an Behringer EP4000 amp. How do I connect 2 x B1520 and 1 x B1800X speakers to this amp? Thanks!


You don't (unless you want two B1520's on one channel and the sub on another). Reading the manuals would help.

The EP4000 amp drives only two channels. It CAN be bridged for one speaker but it won't support two channel and bridged mode simultaneously.

http://www.retrevo.com/support/Behringer-EP4000-Amps-manual/id/23591dj795/t/2/

The B1520 subwoofeer is PASSIVE so it will need a dedicated amplifier to power it and control its volume independently of other speaker channels.

Microphonic tubes can be detected by tapping them lightly with a pencil. I cannot find if this uses a spring reverb, but if it does, vibrating the cabinet will get a clanky type sound from the reverb tank. This MAY use a digital reverb however which is immune to that. Next thing is to make sure your guitar can't "hear" the output sound of the amp because the strings can pick up the sound and resonate feeding back into the amp. You can detect if this is happening by quickly dampening the strings and see if ringing gooes away. You probably need 6 to 10 feet of clearance between the guitar and the amp OR put your body between the amp and the guitar. ALWAYS set sound level at safe levels. Get a sound meter and go no higher than 90 Db. I know a lot of near deaf musicians whose careers are near over because of hearing loss using too high level.

Can't get no output sound from my Behringer PMX660M mixer. All lights are on, power on is on, line-ins work correctly; speakon cables good but sound when instrument played through mixer.


The power amps may be blown... PLEASE read my tip on Fixya about the hazard with PMP mixers if you use Speakon to 1/4 inch cables. The sleeve or barrel of the Channel A plug is the hot, not the tip. Touch it to ground and goodbye Channel A of the amp.

Do this test: Plug a set of earphones into the Main out L and R jacks and see if audio comes out there. (it will only be in one side of the headphone and not too strong... If both L and R have signal there is a problem with the power amp or its configuration. Make sure the slide switch is up in the MAIN L/R position (top position) If all that is correct, the power amps have probably blown. Repair takes a lot of work and getting parts from Behringer now is really hard. The amp module is an HCA2400 and the only source seems to be FullCompass.com...

Hi,I turned on my Marshall mg series 100 dfx and there is no sound,just static comes on.Its starts with a kinda bad feedback sound than turns to loud static.


I suspect the power supply for the effects processor has failed. The effects unit will "go crazy" when power supply is too low voltage.

If the amp has loud noise, then the power amp portion is PROBABLY OK.

I had a similar problem in a Behringer amp caused by a bad electrolytic filter cap.

Connecting a guitar amp to a mixer amp


Hi cliff

Connect either of the XLR DI output of the Behringer directly to a MIC IN channel on the Powerpod using a standard Microphone cable. If you wish to push a stereo sound then connect both(L + R) of the XLR DI outputs from the amp... that's about all you need to do. The only reason you need to use stereo(both XLR Outs) from the Behringer is if you want a full stereo FX output from the amp, otherwise you can get away with 1 connected. You may need to back the gain off for those channels on the power pod. You can get a manual for the Powerpod from here

and user manual for the acx900 here

Hope this has helped you, If not, feel free to ask any questions. Cheers.
