    whole house audio system CHEAP

    ok I have just finsied putting in my homebrew whole house audio system, I must say it works great, I took some ideas from the message board then added my own tweaks to them.

    I mountes celing speakers in every room of the house BUT I added a 70 v transformer to each speaker...
    then I purchsed an amp with a 70V output ( $69 from radio shack ) why? you may ask? well if you do this you have no problems with impedence matching or major level drops when you turn on more than 1 set of speakers, also the transformers have multi taps which means you can set a lower level for speakers in smaller rooms.
    next the switching trick. I saw on the newsgroup about using universal modules, that works ok for 1 or 2 spekaers but I have 14, so I found this:

    it basically is a pannel with 16 relays all x10 controled for $149

    I wired the amp output ionto this and the speakers off each relay, then in the script I just have it turn on the correct relay before speaking or playing music.

    I am also planning on using a smaller unit to switch some cams so i can toggle between night vision and day vision
