Question about Crown CP660 6-Channel Amplifier

1 Answer

Our Crown CP660 is in a church sound system. It's 9 years old. But after 9 years of working flawlessly the last two weeks the sound has been cutting off when more than two mics are live. Shutting off the system for a couple minutes reboots it, but soon the sound cuts out again. What's wrong?

    How long does it run before this problem occurs?
    Check into what speakers are connected and, if you can find someone with a digital multimeter , have them check how many "ohms" the output of the amplifier is trying to power

The UV code has nothing to dow ith oil, poor oil would cause under frequency (low engine speed) Under voltage is caused by excessive load, short in the rotor/stator excition system, and/or AVR automatic voltage regulator. Of course loose wiring to will also cause it.

Miele s314 red star-motor stopped working-on/off switch broken?


Most likely the problem is with the cord winder. This is the most common problem with Mieles. It is actually the most common problem with any vacuum with a cord winder. A Miele repair center should not change you to look at the vacuum and tell you what is wrong with it. The Red Star was a great model and if the powerhead is still in goood condition I would get the vacuum repaired. If it is the cordwinder they can usually be repaired and it should cost about $75.00. If you need a new cord winder this will cost about $150.00. The top piece can be pryed off, however if it feels like it is switching than it is not jammed.

Greg it sounds like you should take your watch to a propper watchmaker. (qualified) Most jewellers are not well educated in regard to watches and their servicing.
