What type of space is this? Residential or commercial?

Hay Nino,

Couple options...
>Commercial, 70v system. You can daisy chain wire from speaker to speaker, which in your case, means one, two conductor speaker wire to each floor, where it will feed all the speakers on that floor. The amp sends out constant voltage to the speakers. Each speaker has a small transformer which pulls a certain amount of wattage from the signal, so, if you have a 100w amp, you can run 20 speakers taped at 5w, or 40 speakers taped at 2.5w etc...You can also mix the taped wattage, sending 5w to speakers you want to be little louder, and a lesser wattage to others for a lower volume.
Search "bogan" and "toa" for info on 70v amps and systems. Also search "70v system" or "commercial audio systems".

>Regular home system. By summing the line level signal from a CD player, you could feed a mono signal into your amp. Feed that into a six way speaker selector and you get twelve, mono speakers throughout the space. More if you use a large speaker transformer. You can add stereo or mono volume controls to adjust levels if needed. You will, however, have to pull home runs to each speaker from the amp, which means a lot more wiring.

Hope this helps.
