Crown CE1000 2-Channel Amplifier - Answered Questions & Fixed issues

How do you know it is shorted. What is the full part number, that number is on transistors, MOSFETS and a few other things.

I have no schematic so I cannot help you. Do you know somebody that has one, if so take a picture of it. Normally if I am not super familiar with something I take pictures before taking apart.

Here's a link to the service manual from Crown: http://www.crownaudio.com/media/pdf/legacy/130352-1_10-02_ce1-2_serv_revd.pdf

setup of bridge mono mode:-1-turn your amplifier off.2-connect input wiring to channel(1) input--3-connect speaker across positive outputs terminals-do not use negative terminal when amplifier is operating in bridge mono mode.4-turn down (fully counter clockwise)of channel (2).

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.

Check to make sure the channels are bridged so both A & B use the same input signal.

If the fan is not working, it could be the fan itself, or it could be missing the voltage to drive it. I wouldn't use the amp with this condition, as you may cause output failure. If you need more information, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

The red and black connectors are the right (red) and left channels for the speakers, so they should connect. However the sub needs a single RCA type phono socket, which should be marked "sub" etc. If it hasn't got one of them you will have problems connecting the powered sub.

Hi,I think this is what you wanted.Thanks,gylacz

I am a musician myself (classic rock band) I too have a crown two Chanel amp , only difference is ours is a 3000. Well don!t feel bad. I had dropped mine more than once and your right, when you turn it on you hear two clicks, one for each side, those are relays that trigger the power to come on and like warm up. I dropped mine one time and both sides were not clicking at all, so I took it apart ( lid off, unplugged of course) located the relays which were pretty easy to find as they were the first switch from where the internal power plug comes in, I moved them around, got lucky, they got loose from when I dropped. Then happened again by a helper, and this time no help. Went to guitar center and they took unit and replaced them, about 40 bucks. That was a couple years ago. Point of my story, this problem seems as mine, and I believe it is going to be a loose or broken relay for that side chanel. Thanks mike, hope this helps.

Use equalizer

make sure the olug in is very tight and the wiring has a solid connection. If not feedback of this sort is very common

I actually had a similar problem with a couple of the 2000w version (band was running two 2000w crowns PLUS another 500w JVC for the sub). We replaced the reset button, and that did the trick, until they completely wore out a few years after that (constant use is harsh on these...).


Hope that helps! Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/cameron_463100ffd54b591d

To determine the current draw (assuming near-unity power factor), divide the input power wattage printed on the back of the amplifier by the line voltage.

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

If your amplifier is working fine then you need not worry but it willonly be the failure of the fan or the power circuit to the fan. Ususally the fan works only when the temperature of the heating drivers goes up beyond a limit. Hence if the fan is not working at a low temp there is no need to worry. power up the circuit and see if this works. If the atmospheric temp is low the fan will not work unless it is kept inside a closed enclosure. so check this out. Other wise check on the fan with a voltage to confirm. if not chekc on the main board for the thermistor trigger to give voltage to the fan. I hope this will work. Good day

Yes, many of the pro sound amps throttle the fan based on an internal temperature sensing device.

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

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).
