Trouble shooting crown xls ampilifier602

SOURCE: I have a Crown XLS 1000 running in stereo highpass

Make sure you are getting a signal into channel 2, A cable swap will tell you this.

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: 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
