Multi Zone System for my home

[tarlkuhn@yahoo.]

I am setting up a multi zone sound system in my home. I want to have 6 zones total. What I want to do is come out the back of my amp in to a speakercraft zone selector and volume control.

Here is the question: If I run all zones at the same time, is this going to damage the amp? I have not bought an amp yet and want to make sure that I get the correct thing. I will pottentially be running 12 8ohm speakers at the same time. I do intend to rock out with the system.

Thanks.

According to the manual, a good quality, 125W or less @ 8ohms amp will work. If you are going to push it, I would suggest an amp that is stable down to 4ohms, 2ohms would be better. BTW, this a separate amp, NOT a receiver.

Impedence matching

I assume that the speakercraft selector box has impedence matching circuitry to protect the amp. This means that a 120 Watt amp will deliver 120/6 = 20 Watts to each speaker. If you want to "rock out" get a more powerful amp (>200 Watts) and speakers with a higher efficiency rating (>90 dB @ 1 Watt) so that the system play louder.

Thanks guys that makes me feel better about the project.

I would look at an amp like the Sonanace 2120 which I believe is stable to 2ohms and delivers 120 watts per channel *2. Keep in mind that driving more than 2 pairs of speakers (4 total) off a single output from your speaker selector really shouldn't be done. The entire thing you should keep an eye on is your ohm load on the amplifier and trying to maintain 8ohms while delivering enough power to the speakers.

This may mean using 2 speaker selector boxes - which would be better than a single box if you have a bunch of areas with speakers.
