Contact the Sunfire tech folks . They've responded quickly for me.
Probably not in the power amp. It's whatever youre plugging the MIC into.

How to record


This is the Amplifiers & Preamps section. You can't record with just an amp or preamp. You need some kind of a recorder. If you have a laptop, it probably has a built in microphone. This provides the simplest modern way to get sound recorded as a file. You can also record from the microphone input on the side of a laptop, or on a desktop computer. Without knowing what equipment you have I cant offer any more detail. Audacity, a free program, might be useful. Google it.

Power goes off when the microphone is switched on why?


Does the microphone have a positive negative grounding switch?
If so make sure it is switched to negative ground. There seems to be a problem either with the socket or the plug shorting, I am not trying to state the obvious but do other microphones give the same result?

Hope this helps, If you need more help do not hesitate to let me know.

Krell showcase amplifier has cracking sound when I play or the power is off the sound like cracking what would be the problem


Just one channel or both? Have you swapped the speaker leads to see if the problem follows the speaker? (i.e. you're sure it's not a voice coil issue with the speaker)

Have you changed the input or tested the other inputs on the amp?

If you have done the basic trouble-shooting, then what's left is a circuit board problem. It could be a capacitor drying out and going "leaky"

The Clip Light and Static ?


I don't know what make & model of microphone or clip light you're using, but try unplugging the microphone cable from the preamp. That will tell you if the problem is in the microphone or the preamp/amplifier.

If you still get noise with microphone unplugged, try checking the power supply. You'll probably hear any hum from power supply. Make sure you're using one that's recommended or sold by the manufacturer.

Finally, try replacing the output cable. Any open circuits in the output cable could cause hum & noise.

That's all I can think of right now. Good luck.

I cannot hear any talking out of my surround sound system only amplified sounds


Check the speaker connections to your centre speaker and indeed the the centre speaker itself in case it has been damaged.

95% of voices are directed to the centre channel speaker (if you don't have one you need to reconfigure your HT amplifier so that it knows and redirects voices to your front left and right speakers)

Fender Champion 600


it is possible to "blow" the input channel if you turn the volume up above a quarter( if it's set by numbers, say 1 low and 30 max then set to 6 or 7)
a microphone has no external power and runs entirley from the voice coil inside(micro volts) and the mp3 playrt will put out volts.

No sound through the speakers...


It may be the PS3
you have to select Optical Out 5.1 etc first.
That PS3 is not user friendly at all.

NAD 302 Amp


Try Earex wax softener, worked for me! Seriously though, are you sure it's the amp, could someone have cooked your speakers without you knowing? Have you checked the media source? Garbage in equals garbage out with any system. Your terminology leads me to think you are an audiophile, so have you checked the stylus? Have you put in some new furniture or rearranged the room. This can make a big difference to the way a system sounds. Check all the usual things like your signal connections. If you have a PC to hand in your listening room, use it as a sound analyser, plug a microphone in and connect the line out into your amp you should be able then to measure the responses of your setup with white noise, swept tones and impulses for room dynamics. I seem to remember there are freeware utilities for this kind of thing. Good luck
