I won't behringer mx3282a power supply circuit diagram

SOURCE: Behringer Xenyx 1622FX. Power supply has failed,

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.

Some of the mixers have common connectors.

It appears that for the three pin connector, pin 2 is center tap of AC source, and pins 1 and 3 are the ends of the transformer windings.

This is from a schematic of a MX2643A which MAY be similar to yours. One of mine has a 3 pin Amphenol connector with a locking screw ring...

Use this info at your own risk, however, the power inout is easy to trace out to verify. They use a typical bridge rectifier to get plus and minus from the external transformer.

The pin markings on the connector CAN be confusing.

Suggest you use the light bulb trick of putting a small lamp in series with the 120 line as an auto reseting fuse.

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.
