Alan,

Thanks for the help- Niles seems to have just what I am looking for. Your reply did stir a few questions so here's hoping you won't get scared off by the quantity and most likely the stupidity in them.

What spec on the receiver determines how many speakers I can drive? Watts?

Don't understand the concept of impedance; Why is it bad to have a low impedance load? Why will a long run help? Is it a kind of feedback on the line? I'm guessing ohms are a kind of measurement of this- I have a switch on the receiver for 4 or 8 ohms, my speakers are rated at 6. What does this measurement mean and should I attempt to match ohms on all of the speakers I purchase?

You also mention protection options- What exactly needs to be protected? Can the amp short out with too many speakers? How do the speaker selectors prevent this?

And in connecting the speaker selector controller would I leave my primary speakers connected to output A and plug the controller into output B or do I plug the controller into A and the primary speakers into the controller. Th first option seems to give me a little more flexibility and might distribute the load better, but....???

Finally, an integrated amp. What exactly is it and where does this fit into the scheme of things?

This is looking like a novel of question that are probably some of the most basic in audio so if you have a good article to link to by all means show it. If you want to take the hour to answer my million questions I would also greatly appreciate it.

Thanks,

Nate

: Nate,

: Speaker selector controllers are availible from Niles in particular which should do what you want. They have many models to choose from with many options from a basic 4 and 6 speaker pair units to models with volume controls for each location.

: Do keep in mind that you are limited a bit on how many speakers you should drive at the same time using the same amplifier, however units as these to take that into consideration and often offer protection options.

: A second amplifier is an option to keep in the back of your mind as you go into this. Depending on the number of speakers you are wanting to add, a integrated amplfier (possibly used?) might cost less and be more flexible.

: Don't worry about your long run of wire. I am more worried about the low impedance load you will be adding - the long run will help there!

: Alan
