Hello,

Can anyone tell me a brand and model of stereo audio swithc 1 INPUT
and 8 OUTPUT for a stereo hi-fi signal, anyone knows if sold on the
web ?

OUTPUT should be possible to select them independently or all
together

thanks

Mario

When shopping at a food store, do you OUTPUT to get in the store, and
INPUT to get out?

Sure. Go to a place like www.markertek.com and search for
"matrix router". Dunno whether the prices for those commercial
units meets your (undisclosed) requirements?

Stereo hi-fi signal? Would that be a line level balanced signal,
unbalanced signal? Speaker level? +4, -10, +8?

Select what? There is only one input.

I think I need what is called 8 way speaker switch

I need to connect a stereo source to 8 pairs of speakers selectable

So you can't use a hi-fi amplifier and 8 ohm speakers - the load will
vary too much between having one pair of speakers and eight. You'll
need a 70v line system. Read about them he
http://www.epanorama.net/documents/audio/70volt.html

The place that sells you a 70v output amplifier and the speakers will
also have switching boxes.

You can buy a device like this from a company like Niles. However, you
will find out that you don't have independant level control, so unless all
the speaker pairs are the same the level will change as you go from one to
the next.

You will also find that the Niles devices present a different source impedance
to the speaker depending on how many you have selected. This will change the
low end response somewhat.

But the Niles boxes have series resistances in them that get switched in and
out of circuit to make sure your amplifier never has too low a load impedance
on it. It's not very elegant but it works okay at reasonable power levels.

I bought a similar product by Adcom about 12 years ago. Like the
Niles, not the most elegant solution, but it is simple and it works.

Would this 6 pair speaker selector help? $31

What does "source" mean? Exactly?
What does "speakers" mean? Exactly?
This is not the kind of thing you can ask as a theoretical
question and expect practical recommendations.
