Hi,

I'm SURE I had this information _somewhere_, but I can't find it when I
want it!


I need to add a separate volume control to ONE speaker in a set that is
run by a PA amplifier, driving a 100V line distribution.

I seem to recall that its not quite the "add a potential divider" type
solution (or if it is, then what sort of pot value to use).


The setup is several speakers in a large room, and one is a much smaller
room, and I need to be able to turn the volume down in the smaller room.


Any clues welcome. Please could you at least copy me with your reply via
email, as I tend to miss things in the traffic level of this group!


Thanks
Neil
