In a distributed audio system in a residence, how can
volume control in each room be accomplished.

(1) Separate amp at each location, not totally impractical
in these days when you can get a pertty fair 100 wpc amp for
under $80 if you look around.

(2) Transformer-type stepped volume controls. Ironically
they are around $30 each, so you're talking a bit less than
half the price of the receiver.
