I have a crown xls602 with no audio. Speaker and power relays activates normally, signal leds palpitates with input but no sound. Appreciate any help. Thank ou.


- Use your favourite search engine (Webcrawler is dandy) and type your question/info into it.
- SEARCH ENGINES ARE YOUR FRIEND!!! Type in keywords and check the results.

- I'm not an expert but it almost sounds like maybe a speaker relay or whatever on the amp has bailed out.

Good Luck :)

Crown XLS 602 power amp: Where inside is the fuse so I can replace it?


Hi Tom,

The fuse you may be referring from the power supply is not

used(none) instead a CB1 or circuit breaker is installed.

These breaker is in series with the power transformer ( trace it).


Disconnect the AC outputs of the power transformer when trying to

reset.( of course with the unit unplugged ).


Measure the output AC voltages, if it is OK

Be happy partially!


Next would be.....


Check for possible shorts on the Positive and Negative Supply

rails to ground or speaker out, for what might have caused the

breaker to tripped.


And these wont be easy troubleshooting , Good luck!!


thanks for choosing Fixya for assistance.

My crown 602 xls tripped a breaker, I reset breaker regained power to receptacle , I lost power to the amp no led's come on front when i pushed the small reset button on the back I still did not regain...


They use a breaker instead of a fuse.

http://www.retrevo.com/support/Crown-XLS-602-Amps-manual/id/19050ci763/t/2/

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.

I have a crown 602 channel 2 shows signal coming in, but no volume comes out. Yet when its bridge it seems to put out more power than just one chanel. Not sure where to start looking into the #2 channel...


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.

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

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.

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

The fault light immediately comes on my Crown XLS 602 power amp immediately upon turning it on. It will not go out?


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
