Europower ep4000 vs crown XLs 602 - Behringer EuroPower EP4000 2Channel Amplifier

There are two similar circuits , use the good channel as a guide in

troubleshooting.

Check your input or output cables might be dirty I had the same problem
and 1 of my output wire was dirty so i sprayed tha electric cleaner and its all good now
Aloha

you are riight there exist several amps like that they having different frequency on each side i supose its not properly made like that or better they wanted a pasty sound on one side and a thin on the other many times it happened to me - in older days specially lots of european amps the solution is a equalizer on the front and equilze it smoth how u want it

They use a breaker instead of a fuse.

CONDITION: No

power to the amplifier.

POSSIBLE REASON:

• The amplifier's Power switch is off.

• The amplifier is not plugged into the power receptacle.

• The amplifier's high-voltage power supply circuit breaker has tripped. Verify that the AC mains

voltage is correct, then press the Circuit Breaker button on the back panel.

Take it to the ER.

Hi...

There may be some internal fuses on that unit.

You can open it by taking the cover off and looking for fuses and discolored parts.

It may have a thermal fuse on the power transformer which then will require service

Check the web for service people in the UK

Lots of electronics have lights (LEDs) that turn on when they are plugged it. Most people just don't notice them. If it is working properly, then the light is normal.

Every time i have this prob i've blown that channel. In my case i,ve had dodgy connections to my speakers and if it is operating with high voltage rails they don't take much to blow.
Take off cover and you will no doubt find fuses somewhere blown. If it has come from speakers you prob done the amp but if not you might be lucky and just have to replace a single fuse or so.Good luck,Paul

Hi try disconnecting the speaker outs and turn off bridge (if its on) If it doesnt work still, then suggest direct to a crown agent. The amp has a 3 year no fault warranty. Hopefully its still in!

All the best
