20 Most Recent Behringer EUROPOWER EP2500 Amplifier Questions & Answers


Hello,
The problem is not bad transistor.
the problem is dirt, try to clean dirt in the internal of the amplifier especially the front section that has a foam attached to it.
this should be done by removing the cover of the amplifier.
Also do not overload the amplifier, check its ampere, watt and ohms to ensure balance of the amplifier and the speaker....

If you are pulling the transistor that drives the final and the problem goes away, is the driver bad? Is the power supply a multi channel isolated unit? Could the channel for that side be bad?

Faichild/Toshiba make the output transistors for the ep2500, part numbers 2SA1943 and the 2SC5200. Beware though there are a lot of dodgy fakes around on ebay. Profusion are excellent. Heres the links for them.

There are so many components that can fail that troubleshooting this can be an expensive problem.

HINT: Put a 150 Watt light bulb in series with the power going into to limit current for/during troubleshooting.

Go through and compare the voltages on the teo channels. If power amp transistors have failed, likely the driver transistors also are gone.

Testing components in-circuit is very dificult. Resistors are pretty reliable and usually show damage by discoloration.

Furhter use before repairing MAY cause further damage.

Unless you are a qualified audio service technician, you should refer repair of this unit to an authorized Behringer service depot. The capacitors you refer to can store lethal amounts of electrical charge. Also, Behringer service manuals and schematics are notoriously difficult to get.

Sounds like a repair shop is best for your needs.

The answer to your question depends on how you want to run the unit and the manual gives very good directions.

when you turn on the AMP and the red light comes on give the amp 2 seconds and turn it back on the red light should turn off. That is what I do with the amps at my church and it works for me, I hope that this works for you too.

Probably the power amp has arced and popped a lot of components.

When teh amps go usually the final pwer transistors, their drivers and sometimes even the power supply gets zapped.

Check the output of the preamp at the inserts for the final amp with headphones to see if anything is coming through.
