Bill:

Thanks for the prompt response. The Shure System I have is as follows:

Mic - Transmitter SLX-2, 2004-DJ1314

Receiver- SLX-4, 1C 618A-SLX-4

Don't know how to determine if the mic is an SM58 with Cardiod response or not. When I use this system with my KN7000 and my Fender PD 250 PA System, the feedback is not too bad and I guess I can manage it. However, when I work with my friend and we use his PD-250 Fender System and he uses his TYROS3 and wireless mic along with a separate subwoofer and his monitor, the feedback is unreal.

My TYROS friends say the problem is the Technics KN7000 and that these keyboards had a real major problem with MIC feedback. I just don't know.

I'm going to drop a note to Shure. Any assistance you or other members can provide will be appreciated.

thank you.
