Jon,

The A/B switch I was referring to was the speaker select switch on the
receiver unit though I was thinking about adding an impedance matching
speaker switch downstream for some outside runs later on to one of the units
feeding one room.

I'm hoping that I can add volume switches to the speaker runs with no
problems as they are supposed to impedance match even when turned off
locally. I guess I'd better check with the dealer because most of the EE
stuff is really over my head as I'm a software type.

I had room volume switches downline on the speaker runs on my old Pioneer
receiver and it worked OK though the tuner in it recently died and the CD
player feeding it started skipping real bad. I chalked both problems up to
old age.

So what did you end up using?

Thanks, for

Dave
