Hi,
I apoligize if this is sounds obvious but I am as they say a newbie.

I am trying to amplify two rooms seperately.
One room has six speakers but I do not need them to be in surround. They will be just for music in a cafe.

the second room will be a screening room where tv, movies, music, presentations and functions will happen. this room will have 10 speakers.

my question simply is how to run this setup? how many amps? a preamp? or just a receiver?

again sorry for the lack of knowledge on the topic but thank you in advance for any help and/or direction I can look in for more information.
