Is it clipping for real or overheating ? It may just be a fault with the indicator light circuitry itself. Make sure the input levels of the amp are matched with the output levels of whatever device is running into the amp, they will either be +4 dbm or -10 dbu, if you have a choice you want them to be set at +4 dbm. Crowns are professional amplifiers and withstand years of hard touring on the road, it would definitely be worth it to take it to a good repair shop if you can't remedy the problem yourself.

It's very likely that the main power amp section has a faulty part on it that is presumably causing an overload. You should check the devices on the main heat sink of the amp section.

Fault light on my crown ce 2000 is on both channels


It sounds like your output transistors are bad or power supply problems. You will need to have it serviced unless you know about electronics and how to repair them. Do not attempt this yourself unless you know what you are doing. It could be fatal.

I recently cleaned out my Crown CE 1000 with damp paper towels and cotton swabs. I let it dry for a few, remounted the top, and fired it up. When I did both fault lights as well the Ch. 2 clip indicator...


Any foreign matter in there should have been dry and loose enough to blow out with harmless compressed air.

A problem that appears immediately after human presence points directly to something that was touched by said human. Only you know the parts you touched or dripped moisture into. The spark is a clue that something blew up but who knows what the root cause would be?

I'd take it to a technician, fess up and hope he can undo the damage.

I wish you luck.

I have a crown ce 2000 watt amp. channel 2 keeps turning off


Do you get any Fault indications?

Have you swapped the speakers around to eliminate them as external causes?

When the channel dies is the unit very hot and is the fan turning very fast (it should be if hot)? The fan could be defective, slow or airflow may be restricted.

Turn the amp off and examine the fan guard on the rear to make sure it is clear of dust and debris. Vacuum it out if necessary. With a small thin non-metalic object reach in and test the fan for free movement by trying to rotate it. It should coast.

I have a crown ce4000 amp. it turns on,but both the fault lights & clip lights are on.i was wondering what could be the problem & what is an estimted cost to repair this amp.


I believed you got 1 or 2 electrolytic capacitors were dry out so it missed 17V + or -- regulators in the preamp sections that why both side light are on If you go to 1 of the service center Crown in your town it would cost you between $100 to $200 I use Australian dollars

Fault lights


I'm not sure what you mean when you say the channel 2 does not work in bridge mode. Bridge mode effectively turns the amp into a mono amp, thus there is no channel 1 or 2. The fans will only turn on when the heat is high enough, so that is not a problem. Please describe what you perceive as the problem with these and I'll try to help.

Thanks,

Electrical prob


This in an indication that there is a problem detected in the final output stage of the amp. This amp will require service. Crown amps are not teh most straightforward designs and should not be repaired by an inexperienced tech. There are high voltages present inside these amps that can be dangerous. The typical cause of this symptom are bad output transistors. Expect a parts cost in the $40 range plus the local labor rate.

Crown ce 4000 amp wont work


Crown CE amps have a very decent service manual that give test points to check for faults. In these amps protect mode is a good sign that major components are not burnt out ie, (Transformer).
With a good Digital volt/ohm meter most common circuits can be checked against the service manual specifications. Usually in these amps the Zener Diode or Capacitors are the first to burn out along with cooling fans. That would be a good place to start.
