Please help me troubleshoot my processor

Indeed sounds like a GL problem. Usually you'll get this from Cable and/or Sat ground loop differential from the reast of the equipment. Easily solved from some pieces from the "shack". Good luck

With the help of some people in AVS, I've troubled shooted the problem. I have a ground loop in my sat sytem. Wish me luck isolating it.

Thanks,
Cap

Does the distortion sound like white noise?

Does this occur with all other input sources powered down?

If you answered yes to either of these, then I would probably take it to a dealer or at least contact Krell.

If it sounds like white noise, it may be that the digital signal is being routed through the Processor somehow and out to the Sub without being converted. If you have another digital source powered up it will feed a signal to the Processor whether you are using it or not. The digital inputs may need to be assigned, the processor may be combining the two signals.

These are just theories. Admittedly longshots, I find it especially unusaual that it effects the sub output only. My limited exposure to the Showcase presented no problems like this, as a matter of fact it worked flawlessly.

Good luck

Even if my Sat Reciever is inplugged. As soon as I complete the digital coax conection from either end, the sub distortion occurs.
