Looking to setup 10 speakers in different locations in a medical office for background music (xm radio). I don't need to spend a fortune, just want a "basic system". I found ceiling speakers from ******************* for $29.00 for a pair.

I have a question about how to connect the speakers. Since there will be a speaker in each area, I would have to run mono instead of stereo right? I understand that I have to get a speaker selector since I don't want to spend a fortune on an expensive receiver. I was thinking about going this receiver:

But this is a 7 channel receiver, how do I go from this to my speaker selector? and do I set the mode to mono in the receiver?

and this speaker selector:
