I am looking into a project for work, I am wanting to build a PA system for emergency information to our building ( Tornado Warning not fire alarm.) we have 2 floors and a warehouse. I was thinking about 1 RP3 to output to an amp connected to speakers however the distance is going to be an issue. Trying to wrap my head around multiple RP3 connected to one for a control panel. I am looking for the control panel to be stupid simple ( one big button …Push to play the alert and loop till button is pulled, kinda like an e-stop button ) If any one can give me some direction on this I would greatly appreciate it!
I have seen some showing multi room music players and I think that is close to what I need, just need the main controller to be simple
Thanks in advance!
