Crown CTS600 2-Channel Amplifier - Answered Questions & Fixed issues

Hi, Here i have added the link to the Operation manual of Crown CTS 600 . Crown CTS600 Manual Ajin

Get the manual out and read page 6 - 7 to find the exact light pattern you're observing. The 'fault light' (singular) flashing is not a documented possibility.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it '*****'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

i had the same problem once and in my case i had accidentally used ground wire for signal. pls check ur connections again. one check u can do is set the high pass filter to 70Hz and see if that cuts out the low hum.

timy check the speaker conections before condeming the amp

On a crown amp you will need a service manual man. That's like working on a Rolls Royce and trying to work on it with Toyota tools. Get the manual or do not wist your time, you will be spending loads of time on this if you don't. If you know where the diff. transistors are, check them out of circuit on high resistance.

I would study the service manual and service notes to find out why the temperature sensors do not work. Probably a supply rail down I would think to affect both of them.

The Power Crown XTi 6000 is a power amplifier, and it sounds like it is activating its protection circuit and not generating a Pulse Width Modulation (PWM) signal. There could be a few different reasons for this behavior. Some possible causes include:

• Overheating: The amplifier could be overheating, causing the protection circuit to activate in order to prevent damage.
• Short circuit: There could be a short circuit in the amplifier, causing the protection circuit to activate.
• Input signal issue: The input signal to the amplifier could be causing the protection circuit to activate. This could be due to a problem with the source, such as a malfunctioning mixer or a disconnected cable.
• Output impedance or load mismatch: The amplifier may have a mismatch in output impedance or the load impedance which can cause the protection circuit to activate.
• Firmware or software issue : There could be a problem with the firmware or software that controls the amplifier, causing the protection circuit to activate.

Without more information, it's difficult to say for certain what the problem is. It's recommended to check the manual for troubleshooting steps and also check for any possible firmware updates. If problem persist it's recommended to take professional help.

Not most service manuals can be downloaded unless you use a model close to the original. Try service manuals.com

Google should have a manual for your 1000 amp thermal and also try on the companies official website too for a manual. Try searching on YouTube as well and YouTube should have videos about amp thermal on - Crown Audio Players & Recorders

Probable power transistor failure.

If you have eliminated any shorted speakers, cables etc, then the only other cause is a shorted device on the power output board. Probably a device on the heatsink.

Hello, Sylvia - I have no idea what entity you meant to receive your question. You posted in the Fixya.com website, which is intended for asking and answering questions on how to go about REPAIRING THINGS. Plus, your question landed in the Fixya category for Crown (brand) Audio Players & Recorders. Perhaps you meant to message Netflix, or your local public library, or a person from whom you borrowed the DVD, or someone to whom you sold the DVD, or . . . Best wishes.

Is the fan supposed to be on. On some units it runs all the time on others when the temp hits a certail level. Which is it for your baby?

It's best to assume there is a short circuit in the power amp board. The unit is going in to protect mode to stop it blowing fuses etc. Could be caused by bad speaker wiring or connections by the way.

Component over heating . Main input output ic defective.

Do you mean that you would like to change from a 3 wire cannon plug to a 1/4" female?

Replace/repair fan.

That is a subjective statement. You need to measure the SPL at the speaker and check against the specs and also measure the power from the amp to have the data to check and compare with. That will give you an objective answer. You could have lost part of your hearing, I do not know!

I would suggest you take it to your local Crown repair depot. It sounds like a fault in the internal protection circuits or the outputs are blown. Without a lot more information I cannot help.
