Re: TTS and how to do it?

["Frank Mc Alinden" <armagh@xxxxxxx>]

Hi Ken
            Dont
know much about audio , but i think you will load your amp
if you put 8 speakers in parallel. Personally i think Shanes idea is what
i
would be looking at.  Small amps in each zone (room)
with a mute input controlled by HA PC or Homevision.
