Crown CE1000 Clips out when signal attempts to pass

I turn on the amp and it goes thru its warm up with the blinking Fault lights seems ok, I can hear a slight hum in amp and thru speakers as soon as I attempt to pass a signal it clips off then comes back only to clip off again as soon as signal tries to pass. I noticed theres two jumper clips on the board that are only half on, not sure if I should engage them or not went to the Crown site read schematic and there seems to be notes for these jumpers but could not find them on the schematic anywhere could this be the problem. Help me please Thanks

SOURCE: CROWN CE1000- slips into fault immediately after connection

if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

SOURCE: Crown CE1000 and CE2000 both clipping with low signals

for some reason channel one of one of our amps started clipping. i first noticed it with the drum kit but it slowly moved to the vocals as well. i haven't noticed this issue before today. what do i need to adjust to keep it from clipping?

Without any audio source or speakers on output attached, the Crown CH1 Amplifier (as soon as you put the on/off switch to the ON position, the CLIP light blinks a couple times and the FAULT lights blink...


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.

The fan on my CE1000 does not come on when the amp is powered up. The amp seems to be playing normally, but I am afraid I may over heat the amp if the fan is not working. Is this normal?


The Thermal Senser on the Heat sink may be Defective. Heat the Thermal senser and see if Fan Turns on. It is a device with 2 screws holding it to the heat sink

Fan running


This is a very sophisticated amp and it will turn the fan on at various speeds when it feels the need for it. Of course, if it's running REALLY hot, going into thermal protection and/or posting a fault you might take a look at it to see if it CAN turn (no obstructions).

The fault lights are blinking. No audio


If the amp is going into protect without audio passing it could very well be an internal short. In this case audio typically won't pass at line level. Have you tried turning the input gain stage knobs all the way down as well as the source material and slowly creep the volumes up? If it takes some audio before it faults you may want to double check the load you are placing on the amp's outputs. I'm assuming at this point it doesn't matter what speakers you are hooking it up too, it still crashed on you. Remember that Audio can be measured in voltage as well so you can measure the outputs of the amp with a volt-ohm meter.

I have a Crown CE1000 power amplifier. I turned it on the other day and I seen a bright flash inside of it. Now the fault lights are blinking and it won't work. Is there something that I can look for or is...


Unfortunately Crown amps are not the easiest to repair as they utilize multiple levels of amplification. Since you saw a flash, a resistor probable smoked, I would recommend that you bring this to an authorized service center.

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.

Cuold be the final power amp ic. Might be imput transistors to that channel. Its possible to have a cold solder joint on pcb.
Look close at board with good light and a mag. glass to see if any foggy looking joints and heat up with soldering iron then dab with fresh solder.
Good Luck
