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...

Where are the main speaker cables connected to in a behinger europower pmp 2000 mixer amp


The Behringer PMP2000 uses Speakon jacks on the speaker cables. The outputs are located on the back panel. Which ones you use is determined by how you configure the mixer. The Main inputs are located on the right side of the face of the mixer.

Chances are you've blown the output transistors. Speakon connectors cannot short out but jack connectors can and if it was not inserted properly you'll have presented a dead short to your powered mixer. In any event it is really bad idea to connect anything when it's switched on. If you're really lucky replacing the output stage (which will probably be dead short on the transistors) and re-adjusting the bias should sort you out.

I don't have a problem. Just a question. I have a behringer pmp3000. Where is the best place to connect two mackie active speakers for maximum results.


There is no such thing as "MAXIMUM" results... Connect the speakers to the MAIN L and R jacks on the face using 1/4 inch TRS (balanced) interconnect cables. DO NOT USE TS unbalanced cables!!! Also an absolute requirement is that the connected active speakers are powered from the SAME receptacle as this mixer. Yes, this means running extension cords, but unless you can tolerate noise due to ground bounce and damage to your equipment respect this requirement... it isn't in the manuals but is well known among professional sound people. Also please read my tip in regard to a hazard for PMP mixers on Fixya tips regarding Channel A when using 1/4 inch adapters from the Speakon outputs.

No power from amp outlets ..rest of mixer works fine


The amp module has likely blown. Repairs can be exetensive within the module. Try cycling the power as there is an overcurrent sensing in the amps that locks the switching signal off. Let the unit remain off for several minutes and retry it. This all assumes it has worked before and the cables are good. Also please read my tip on here about PMP mixers regarding a hazard on the A output when using Speakon to 1/4 inch cables. The A output s;leeve of a 1/4 inch jack is the HOT, NOT the tip of the plug, unlike the B output.

Where (on-line) can we find download for advanced manual for Behringer PMP 4000 16 channel powered mixer? What we found on-line was the exact manual that came with the mixer.


There really ISN'T and "advanced" manual... Everything you need to know is in the user manual that comes with it... Service manual with schematics will not give you much you can use unless you are into electronics detail.

PLEASE read my tip about Behringer PMP mixers on here regarding a hazard if you use Speakon to 1/4 inch cables or adapters. Essentially, the sleeve, NOT the tip is the HOT lead for a speaker on channel A. Ground it inadvertently and goodbye channel A amp.

Be VERY careful of speaker leads with this amp as it is easy to pop a channel IF a speaker comes loose or shorts. Loop cables through the handlesto avoid cables being yanked out or breaking plugs.

New to the mixer world. i have a dicontinued pmp5000. can't get the bridge mode to work


You require a special cable with the Speakon copnnector wired a special way. Refer to your user manual for the correct pin connections to use bridged mode and then put the slide switch in the position closest to the effects display.

Refer to figure 4.6 on page 10 and figure 4.7 showing the connection for bridge mode.

NOTE: you cannot go below 8 ohm speaker on the bridge mode... that USUALLY means a singl speaker of 8 ohms... you CANNOT parallel two 8 ohm speakers.

The single speaker cable will plug into the "B" output connector. Remember bothe the barrel and the tip of the connector if using 1/4 inch plugs is HOT and grounding either inadvertently will fry the amp.

My PMP 3000 is a dead stick. Help? We were playing a gig and everything was sounding amazing, all of a sudden the volume on channel 2 (a Wireless Digital Reference Head Mounted Mic, gotta love drummers)...


Please note that the outputs of the MAIN L/R line outs are TRS balanced. If you plug mono plugs into these or connect to mono device you MAY have a problem of grounding out half of the drive internally. ALSO please read my tip on here regarding a polarity hazard of speaker cables of PMP amps if you do NOT have Speakon to Speakon cables, but have Speakon to 1/4 inch cables.

Likely one of the power amps in this has failed If no lights come on the unit now, then the power supply is wiped out as well. It takes about $50 worth of parts and quite a bit of skill and work to restore the unit, including carving out burned board and re-insulating. Likely a feedback occured on that mic and started the whole thing. Supersonic feedback is something most musicians are NOT aware of, but if the feedback is above the range of hearing, the amps can be strained as they may go to maximum power trying to amplify the sound you can;;t even hear. Piezo tweeters are capable of frequencies up to 30KHz.

If this is under warranty exercise it immediately.

With the failure in 3 wks, IMMEDIATELY take it in for warranty replacement.

Please read my tip on here regarding polarity difference of speaker cables when using Speakon to 1/4 inch plugs.

Any flakey thing in the sppeaker system such as cables, connectors, and the speakers can cause the problem.

Fuse blowing on start up on Behringer PMH 518M


Try running the amp with no speaker cables connected. If it doesn't blow the fuse you know it's either your Speakon cables or the speakers themselves that are to blame (it's usually the cables)

If it still blows then there is a more serious problem with the power section.
