Whole House Audio

["Simon Brazier" <simon@xxxxxxxxxxxxxx>]

I'm trying to come up with a plan for a whole house audio system, but have
a quick question I hope someone can answer.

If I use a volume control such as

to control the volume of the speakers in each room, would it cause any
damage to an amplifier if it was driving a signal into a set of speakers
that had been turned off - possibly for periods of a couple of days ?

Thanks in advance
