How to fix aux send on behringer xenyx 16 mixer

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.

Hope this solves your problem. Thanks for using FixYa

SOURCE: whow i connect my xenyx 1002 mixer to audiophil 2496 sound card

You must connect:
the main out of the 1002, or the ctrl room out of the 1002 at your power amplifier's input.
the line in 9/10 of the 1002 at your 2496's line out.
the cd/tape out of the 1002 at your 2496's line in.
in case of a cd connect it's line out at line in 3/4, or line in 7/8 of 1002
some mic at the mic 1 or mic 2 of 1002.
That's the way you're going to have control for:
the mic level from channel 1 or 2.
cd level from channel 3/4 or 7/8.
pc playback from channel 9/10.
master speakers from main mix or ctrl room.
All the above connections are not absolute and may vary depending on your needs.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

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: LEVEL POT ON A BEHRINGER EURORACK MX 602A-BAD

It appears that both these use a 50K pot in the identical circuit and it is UNLIKELY they re-engineered very much so it is likely they use the same pot.

Behringer parts service should be able to tell you.
