I have a crown xls 602 amplifier there is no output on both channels. all the components seems ok on testing and i get the signal from the potentiometers. It looks like its muted , pls help

SOURCE: left channel not operating on crown xls 602

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

SOURCE: There is a red light shinig inside my CROWN XLS

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.

SOURCE: No power to Crown XLS 602 Amplifier

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

SOURCE: I have a crown 602 channel 2 shows signal coming

Common problem. Power transistor in channel#2 is weak or out completely.
Bridging converts from 2 channel(stereo) to mono and you are are useing both channels in series to effectivley double your output.

SOURCE: Got a crown amplifier XLS 602 its powering up the relays are clicking, all voltages seems ok the signal led's are on but there's no sound output on both channels. I manage to trace the signal

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
