<div>You are so over thinking this.</div>
<div> </div>
<div><a href="http://sound.muzak.com/assets/pdf/how_to_design.pdf">http://sound.muzak.com/assets/pdf/how_to_design.pdf</a> describes how to calculate the wattage needed for your amp. You are using commercial sound system speakers correct?</div>
<div> </div>
<div>Now you need a cheap 70V multizone amp like this one: <a href="http://cgi.ebay.com/4-Zone-Commercial-PA-Amp-Amplifier-New-WELTRON-Quality_W0QQitemZ230356340271QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a24ece2f">http://cgi.ebay.com/4-Zone-Commercial-PA-Amp-Amplifier-New-WELTRON-Quality_W0QQitemZ230356340271QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a24ece2f</a> You could </div>
<div>probably get a great deal on a used one on ebay or craigslist if your patient.</div>
<div> </div>
<div>Finally, use your software to output a Mono signal from your laptop, or let your amp down mix for you if it has stereo inputs (like the one above).</div>
<div> </div>
<div>Commercial systems are nothing like a typical home setup, and should not be treated as such. For example, if you use standard 8ohm speakers and run 3 of them together in parallel off your amp, you will present your amp with a 2ohm load, effectively drawing 4 times the current from the Amp... and likely blowing a fuse. Commercial speakers are very different and much more suitable to this application.</div>

<br>I'm trying to design an audio system for a restaurant, and they want 3 zones of mono sound. I'm looking for something that I could input stereo audio, and output 3 mono signals that combines the stereo input from a netbook running iTunes. I'm planning to use 3 "V-12M Muting Wall Mount Volume Control" units from (<a href="http://www.ecost.com/detail.aspx?edp=37244640&source=ecostdeal&cm_mmc=CSE-_-Shopping.com-_-ecostdeal-_-Electronics" target="_blank">http://www.ecost.com/detail.aspx?edp=37244640&source=ecostdeal&cm_mmc=CSE-_-Shopping.com-_-ecostdeal-_-Electronics</a>) to independently adjust the volume in the three zones (back room, front room, outside). My plan is to find a home theater 5.1 surround system that I can set to output a mono signal to at least 3 of the channels, and then run them through the independent volume control units. This is just background music, so absolute quality isn't a requirement, as long as it provides a reasonably clean signal (I'm not looking for insane audiophile level quality, something equivalent to the audio played from a TV for example, just no obvious noise that would be noticed in a loud dining room). <br>
<br>Is my approach reasonable? Any obvious holes in my plan? Is there any magic product I can find that would do this all from one unit for a reasonable price (a price comparable to a low end 5.1 surround sound receiver)?<br>
<br>Any advice would be appreciated. <br><br>Thanks,<br><font color="#888888"><br>Josh<br>
