Hi Dave!

Sure - it's really simple:

I have 16 ceiling speakers throughout the house.  To drive those speakers, I
take the output of my sound card into the primary of a 70volt speaker
transformer.  The output of that transformer feeds the 16 relays on one of
my Redacs.  The output of those relays in turn feeds the secondaries  of 16
different 70volt transformers.  The primaries of these 16 transformers feed
the speakers in each room.  Make sense?  I then use ECS to close
one/some/all of the relays depending on how widespread the message to be
spoken needs to be.
BTW, the amp in the sound card is plenty loud enough, in fact, I only have
it up about 3/4 of the way.

Cheers!

Michael David

Michael.

Would you consider posting your general hardware setup in regards to audio
announcements? I would like to do something similar as part of a paging or
intercom style system.

Thanks,
