SOURCE: Hello; I have a used Behringer pmp5000 mixer. The

Without knowing how you have your monitors configured it is hard to analyze what you have posted.

In brief, SW3 on the schematic that selects MAIN L and MAIN R in the upper position, MAIN and MONITOR in the middle, and bridged in the lower is used to configure the internal amps.

In the upper position, the amp power outputs come from the mixed stereo bus and are simultaneously controlled as a stereo signal by the MAIN slider.

In the middle position MAIN and MONITOR, the left amp receives the signal from the mix bus and is controlled by the MAIN slider. The MONITOR output from the other side of the power amp is controlled ONLY by possibly the "MONO" slider.

The schematics are hard to decode and what is needed is a signal flow diagram.

For my uses, I don't try to use splitting the power amps between mains and monitor but prefer to use the mains together with SW3 in the upper position (Note your 27 may be refering to the user manual designation for same switch). I then use another small amp from the 1/4 inch MONITOR jacks whcih are under control of the MONITOR sliders.
Please note that the MIX for these two MONITOR channels is controlled by the MON1 and MON2 knobs for each channel.

Usual problem is the Channel A amplifier has burned and blown the switching transistors. Usually an internal board arc occurs and unless very skilled at board work of clearing the burned area and replacing the components you are better to replace the HCA2400 amplifier module... about $160

SOURCE: I'm having problems with a Behringer PMP5000 board. the dual effect chanel instead of number 0-99, it come up as letter and number i.e e1-5

In spite of the display, does the effects work and do they change when you dial up and press the knob down? If they do, then likely the display is at fault. If the effects are NOT working sound wise, check the +5 volts as the whole effects runs from that, It should be within 10% of the 5 volts.

Behringer PMP5000 Mixer. Connected a speakerOn cable to Output A while device was ON. Went to do the same thing on Output B and heard a spark. Turned off the mixer. Now, it will not come on. Checked the...


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.

One side of my europower pmp 5000 is out, the other is fine.....what up?


What is up is one of the two power amps is blown... I know this problem... It is USUALLY the rearmost channel which goes to the left Speakon faacing the back. Weak insulation between layers of the multilayer circuit board arcs and fries three transistors and a diode and sometimes a few more components. It takes a lot of skill to restore the module and is beyond most repair shops. A whole new module costs about $155 from Full Compass. The amp is an HCA2400 module, but you MAY need the Behringer part number to order it from Full Compass. Also please read my tip on Fixya for PMP mixers regarding the hazard when using 1/4 inch plugs from the Speakon connectors... the Channel A sleeve is the "hot", not the tip and if you ground the sleeve, goodbye channel A...

Here is your service manual: http://elektrotanya.com/behringer_europower-p0569_hca2400_sps1000_dpx_pmp-1280s_5000_sch.pdf/download.html

Scroll down to "get manual" and click to download. Ignore other "download links".

You will likely find that one of the power amps has shorted... been there, done that several times. Usually the channel A (rearmost) power amp shorts takeing out the 9140 Mosfets and other parts. Often an internal short between an interior and upper layer of the amp circuit board is the fault that causes all this. Use a light bulb (150 watt) in series with the power input when testing after repair. Use an isolation transformer when working on the supply for personal safety. When supply is running again, discharge the 70 volt source caps before plugging onto the amp to avoid welding arcs at the connectors. I have seen the supply hold charge for several days.

Fan doesn't when 6pin cable between power supply and PA, is plugged in, however fan works when disconnected from PA board


The fan control receives two signals from the HCA2400 power amp module. Pin 4 is labelled POS+ and pin 5 is labelled POS-.
These two interact with T14,T15,T16,T17, and finally T7 which gates a -21 volt power to the fan.
From the schematic, it appears that if POS- is more positive than about 20 vollts negative the fan will be held off. It appears that the POS+ signal controls the speed and as it goes more positive, this would DECREASE the speed. Pots VR2 and VR3 are used to set these thresholds and I do not have setup instructions for those... I would be very careful about adjusting them without the procedure. . HOWEVER, first thing is to verify that you have -21 volts DC on pin 2 of the fan connector. With the HCA2400 disconnected, the POS- will drift to -21 volts and POS+ should drift to somewhere around -6 to -8 volts judging from the schematic.
Trying to trace these two signals on the HCA2400 is very difficult and the schematic does not show where they go... I did find that pin 5 does go to one of the thermistors on the heat sink labeled R2 and one side of R1 goes to pin 3 which is -12 volts by tracing an HCA2400 I have open. Pin 4 seems to go to the other side of R2 so then the R2 thermistor connects between POS+ and POS-.
The room temp (71F) resistance of R2 seems to be about 112 ohms and rises with increasing temp. It appears that R1 is involved with a signal sent to the power supply called OFF which probably shuts down the supply if the HCA2400 gets too hot... so R1 thermistor on the HCA2400 would have nothing to do with the fan... I can;t verify that R2 does more than connect to pins 4 and 5 of the connector... there may be biasing resistors on the HCA2400... I would find it odd that VR2 and VR3 would both be connected in series effectively with R2 thermistor... so I suspect there are additional biasing on the HCA2400 that one of the tweek pots conrols the ability to run and the other controls the speed above that... Please note that the resistance measurements of R2 are made on an HCA2400 that a hacker all but destroyed...

I am thinking of buying a pmp 5000 from a musician and he said th fuse blew. it wont power up and he said everything went off all at once and wouldnt power back up! he had 3 sets of speakers hooked up and...


No! I have two of the PMP5000 and one PMP3000.

I could tell you what parts are blown. If nothing lights up what has happened is the power amp (Usually the rearmost amp) has arced and destroyed the three switching transistors and a Zener diode and sometimes a metering resistor and two surface mounted transistors. So far parts cost is about $20 and a LOT of labor.

Since the fuse blew, it is possible as is often the case, that the power supply is also damaged. Now the total parts cost is $50 as two expensive IGBT's are blown, a regulator IC and four driver transistors for the IGBT's and one other surface mounted transistor and usually a diode. If a fuse has been repalced, then often a pair of power resistors associated with softstart are blown. A lot of labor is necessary on the power supply to remove the heatsinks that the IGBT's are on to replace them.

If the amp module (HCA2400) were the only thing, you can get those online complete for $175. Repair of those requires a lot of skill carving out burned board between layers of the multilayer board and restoring connections with jumpers.

You are probably looking at $300 parts and labor to restore this unit. I fix them for my own use, not others.

There is a weakness in insulation between internal and external layer of the circuit board near the rearmost amp and if you play it real load and had a speaker lead come loose the unit can arc and it is all over. There is also a polarity hazard. PLEASE read my tip on here in that regard about this. This applies to the PMP3000, PMP5000, PMP1280 amps.

My behringer powermixer is making a clicking


You have blown the power amps in the unit. This is why you must insure that the speaker leads cannot be unplugged while unit is powered.

I don't know what model mixer you have, but ones like PMP3000, PMP5000, PMP1280S use a switching class D amp that arcs through a circuit board.

One can get a replacement:

http://www.fullcompass.com/product/375886.html

I have NOT done business with this company before but you need to see if the HCA2400 module is what you have in your unit. Note that it has covers on the unit pictured at the site when installed.

I have repaired these, but it is an extensive process including carving out burned board material and replacing many components.
