RE: [ECS] Dedicated Speakers vs Local Phone Sessions Michael David Thu, 27 Aug 1998 20:53:07 -0400

Hi Ingo!

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.

The amp in the soundblaster card is plenty loud enough, in fact, I only have
it up about 3/4 of the way.


Cheers!

Maybe I should break down and hardwire something... but I can't afford
one of those whole-house multi-amplifier jobs.  So I'd probably have
to buy a few cheap sets of computer speakers and run line-level audio
to each.

Would that sound worse than the wireless?

What brand/model are those?  Have you tried others as well?

I found this on the net: http://www.recoton.com/docs/wire432.htm and
