I'm new to the 70v system and need some guidance and knowledge re: setting up our customer service environment.

I have (2) CSMA 280 and need to outfit them with more speakers. Additionally, I have (9) press-to-speak microphones that will be working in conjunction with these Amp/Mixers. The environment is odd (isn't everything with COVID these days) with (1) common public space and (3) areas separated by plexiglass. I'm not knowledgeable re: 70v wattages and what's needed for decent volumes.

I'm simply trying to provide low level background music, with the capability for customer service representatives to speak into their microphones while ducking (muting) the background music momentarily.
