Power supply circuit diagram


There is almost certainly a reason the PSU has blown, these are not very reliable units and the amp has probably gone and taken the PSU with it. You are better off taking it to a dealer and getting it fixed. If there is no power on the seecondary and there is no short the transformer must have blown (assuming you're not trying to check with a DC meter)

Behringer sx3242fx not working .i need circuit diagram .


Behringer will not release schematics unless you are an authorized service agent... however, sometimes you can make do with the few schematics floating around... What is the problem with the unit? They typically use a switching power supply and the schematics of those aree usually similar enough to repair them.

Behringer DDm4000 purchased in 2009. Over 2 years happy usage, but now it's got some major issues! The power supply seems corrupted as after about 2 hours use it maxes out the signal (ouch) and all...


Behringer is stingy about schematics... however here is one for their DJX700 which MAY have a similar power supply to yours:

Scroll down to "get manual" and click to download... IGNORE other download links.
On page 9 near the lower right corner is the simple power supply, minus the transformer but showing the rectifier diodes, filter caps, and the three terminal regulators. These regulators have a thermal shutdown feature so if they seem to run VERY hot they might cause your problem. Common things are failing electrolytic filter caps. Behringer also uses switching power supplies in some gear and I have schematics of examples of those as well... but peak in your unit and see what type supply you have.

Im looking for a curcuit diagram for the switchmode power supply in my Behringer PMP3000.


If the supply failed I can tell you which parts to replace... and if it failed there may be a failure in the power amp that caused it. You can contact be directely at fredy2 @ aol.com... put Behringer in the subject.

The supply when it fails takes out eleven components including two expensive IGBT transistors. If the rearmost amp fried, add at least four more components and a lot of work carving out burned board and wiring around the blown circuit traces.

Behringer Xenyx 1622FX. Power supply has failed, no +5V rail, other rails are OK, appers to be no input to the regulator. Could do with a circuit diagram. I believe the PSU is used in other mixers.


Suspect a broken circuit trace or broken solder. If they use a 7805 three terminal regulator, check the solder around those pins...
Berhinger does NOT release schematics except to their service facilities... I know... I have tried... I repaair a lot of their stuff and have to trace out the circuits.

Power supply circuits are rather easy except for the switching regulators if they have failed totally.

If only the +5 is dead, you should be only a filter cap and a diode or two away from the problem... Transformer leads and electrolytic leads with their weight are favorite to pull out of solder... On Behringer, often the traces are narrow and can have a crack in them.

External power problem


It's actually the opposite. 1/8" jacks are almost always positive tip. I think you are best off using a 9VDC supply. If the voltage is not staying constant at 9 volts it could certainly do damage. If the supply you used was a negative tip positive sleeve you may have burned out a component or two...and more voltage than recommended could have done some other bad things. If it does not work with a 9VDC supply with the correct polarity you can fix it yourself if you have electronic experience. You could also send it to me and I'll fix it at a reasonable rate.

Try contacting their service center rep at (801)566-8800. They might send you a schematic for the pedal if you explain your situation. They do recommend using the original power supply PS0912 which should still be available. Hope this helps.
