20 Most Recent Crown CM-311A Professional Microphone Questions & Answers

It looks like a mini XLR connection at the belt pack end, so that's easy. The cable goes to a connector block which looks like it is held together with two screws. Again, that should be fairly straightforward. The other side of the block is the cable that goes up to the head set and boom mic. This looks a little trickier for a novice just because the mic capsule is small; the cable runs through a narrow diameter tube, and the cable routing involves heatshrink. At a guess I'd say that the foam windshield will come off. There'll be a grub screw holding the collar in place. Personally, I'd use a meter on continuity setting, upen up the XLR and connectors block, and test the two signal lines (pins 2 and 3 in the XLR) for a break. Fingers crossed it is in that section. Then replace that cable. If it is in the boom arm section, and you feel confident dealing with threading the cable and using heat shrink then have a go. If not, take it to a Tech to avoid the risk of wrecking a great mic.

That should shed some light...might have to through solder on to the circuit board should be relatively easy!

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.
