Uncle Dave,
How are you using your PAS?

I had a first try today at a church and it was feedback all over!!!

The room was pretty big, easily hold 350 people. I used a mixer, all effect turned off. Two mics on the first two XLR channel, my PA80 was on stereo Ch.11/12 and my Yamaha S90 on stereo Ch. 13/14. I run the main L/R out from the mixer into inputs 1 and 2 on the PAS. The Bose setup is about 10 feet behind me.

If all mics were off, I can blast the music as loud as I wanted to, but as soon as any mic is tuned up to a decent level, I got feed back all over! I can turn the whole system down, but then no one can hear anything well, including myself.

How did you do it? Tonight was a test run, tomorrow night is the real night. I still have tomorrow day to work it out.

Who knows, the 30-day money back from G.C might come in handy this time.

Many thanks,
..rb
