Audio Systems: Home audio, impedance control, power amplifier


Question
Hi Mark,
I have a couple of questions about setting up a small multi-room audio system. I will have speaker pairs in 3 separate rooms and was planning on controlling these with volume impedance controls.  It is my understanding that i will run 2 wire cable between the impedance control and the speakers and then 4 wire cable from the impedance controls to my receiver.  Is this correct?  Also, do i need to have a connector box or can i wire directly to my receiver?  Can you make any recommendations about good quality impedance control devices? Final question regards connecting my computer to the receiver, what is the best way to do this?  I currently use a wireless connection but the sound doesn't seem very good.  My computer a digital output, is that preferable to using the "y-connector" with rca ends for the receiver and the single jack for the computer.  Sorry about the long-winded questions, thanks for the help.  

Answer
can you send me a link to the units you are planing to get? The wiring will be different depending on the type of Lpad you're getting.
Personally I wouldnt find the impedance controls acceptable I dont think.  I'm not a fan of passive devices like this.  Not sure what I'd do.  probably get some amps and put them in the separate rooms and just run RCA lines to the rooms. I'd get amps like this:

that way there's plenty of power to go around since each set of speakers has its own amp and there's no issues with impedance and no sound robing passive devices.
I know its more expensive that way and there's a piece of equipment now in the room that wouldnt be there but those things are less important to me than the better sound quality and such that this would provide.

for the computer to reciever, if they are close enough that running a wire is pracital, the 1/8" stereo to RCA adapters are great for this, you can get the at radioshack in 12' lengths and if you have to go further, you can use an 1/8" headphone extender cable.
My pc and home theater are in 2 separate rooms so I ran a piece of standard computer cat5 wire and use 2 out of the 4 pairs in there for the left and right channels.  you can solder your own jacks on the ends (jacks also available at radio shack) and the sound quailty is perfect even over a few 100 feet. The digital cable is great too but then you have a distance limitation usually.
Let me know what you think.
