Hi Bill:

Appreciate your trying to help me out.

Just spent the afternoon working on the problem. I would prefer to use the Mic system of the KN-7000 in order to avail myself of the adjustments available within that system. However, the feedback problem is continuing. Switched the MIC input to direct into the PD 250 and that solved the feedback problem. I'd still like to use the KN7000 mic system but that will have to wait for another day.

Thank you.

Len
