In my opinion, due to the physical appearance of pmp4000 and pmp3000 look the same, it will most likely also have a common circuit and parts list (at least, most).
Usually Behringer (and all the manufacturers), with the same series / sequence, using the same circuit, the difference is the number of channels only. You can compare the parts list on PMP3000 schematic, with your PMP4000.

Hope this helps.

If the transistors you seek are T2 and T3, they are the power mosfet's and the part number is IRFP32N50K for both. As far as the schematic is concerned, the PMP4000 is a very hard one to find, if you can at all. However, the PMP6000 has a very similar set up and the switching power supply boards are exactly the same board. SMPSU29 is the board in both. The PMP6000 schematic is very easy to find online and as far as I know, the PMP3000 schematic is not as comparable as the PMP6000 is to the PMP4000.
SOURCE: i need a wiring diagram for the main circuit board
Behringer only gives schematics to their authorized service people.
I find I can usually trace stuff out as needed as the mixers are a very symetrical repeating circuitry.
Most components are readily available from other sources.
SOURCE: Need Behringer Eurorack mixer power supply connector
Those were used for mic connectors at one time,,, they are related to the Amp 91-MC3F family of connectors and those are out of production and they are demanding $20 to $50 for one connector.
That is a ridiculous price and I would be tempted to swap out the connector for a more available design.
On eBay item 250401122616 is one but they want $13 pus $11 shipping which is a rip off.
These were used on some OLD CD radio mics.

Hi,
You can download the manual by clicking this link
You'll require Adobe PDF Reader installed on your PC to view this manual. If it is not already installed on your PC, download it free from:

Hope this solves your problem. Thanks for using FixYa
SOURCE: Behringer XENYX 1622FX, won't power on. Phantom power works(?)
After reviewing the schematic, I don't understand how the Phantom power can REMAIN on with the power switch off... this CANNOT occur except for what energy is left in the 48 volt supply filter cap... This might last for minutes after the fuse went... UNLESS you have devices connected which are backfeeding the 48 volts. (which would be a disaster)
The 48 volts, +/- 12 volts and +/- 15 volts and the +5 volts ALL come from the SAME switching power supply. I suspect one of the filter caps went or the primary switching regulator a TDP245Y chip.
You should ONLY work on the line side of this using an ISOLATION transformer since the line side has lethal voltages.
To do testing, one replaces the fuse and puts a 60 Watt light bulb in series with the hot side of the inout line. The lamp "acts" as a resetable fuse and limits the current for testing. When all is well again, the lamp will remain out with the power flowing through it.
The D1 diode bridge and C7 input rectifier and filter are first things to check. You can do those with an ohmmeter.
I will caution you to ALWAYS power any and all equipment from the SAME power source. Plugging in devices from across the room will set up ground loops and any ground fault will fry equipment.
SOURCE: hi all i own a behringer
You would need TWO DC supplies as they use AC so they can create both a plus and minus 15 volt power source to run the internal op amps.
Here is a schematic for the 1202 which has same power supply configuration as the 802.

Scroll down to the little link "Get Manual" and download the service manual and schematic. You will find the power input in the upper left corner of page 5.
