[QUOTE="Charlie Zureki, post: 48034, member: 153"] Re: Connecting to a "house system" Hello Dick, I think that the 70v system had a speaker or speakers miss-wired.....using the 4 or 8 ohm terminals on the speaker(s) instead of the appropriate terminals. I've had the exact same thing "fuzzy" thing happen in a theatre's 70v system for the dressing room and office speakers. And... it seems that the volume control was incorrectly wired (building up a rather large capactiance (impedance change) or just plain intermittant (with the level drop) Good Luck, Hammer ps...if you're feeling up to repairing their system... change out the volume control regardless, and add another local control for the other zone, and then check all speakers in the system ...starting with the one in the control room, then any lower mounted....hallways and offices....
