What is the best way to install a speaker system in several restroom all connected into one box, but each with individual volume control as well as a protective system around this control unit were only selected people may use this control?

Of course, if you know not the answers to all of these but one, please do answer with the one thing in-which you do know. ^-^

Answer
I would recommend a 70v system. this will allow you to have many speakers connected to 1 amplifier. and you will be able to tune the volume at each of the speakers.

companies like TOA sell 70v speakers for indoor / outdoor , on wall or in wall mounting

What kind of receiver do I need for my in-ceiling speaker system?

I just bought a home with a speaker system built in to the ceilings. There are two thick yellow cables coming out of the wall that each have a red, black, white, and green coming out. The home has 5 rooms with volume controls.

My audio knowledge is pretty low. I would like to know what kind of receiver I need to buy (maybe even an amazon link?) and how do I hook up the different cables once I have it? Please and thank you!



Answer
You are going to have to contact the installer for a definitive answer on this one. Yes there is some logic to the color scheme, but let's not take a chance here. Somewhere there has to be a business card tucked in or a label placed somewhere. The same company may have installed an alarm system - so take a look there too. Don't overlook the doorbell (seriously).

I will share an experience I had hooking up a stereo system to a pre-wired house that may help if you can't find information about the installer. The red wire will be right/positive. The white wire should be left/positive. Black and green should be negative - but not sure which channels. You can use a digital multimeter and place one test lead on the red... then see which other lead gives you a reading of a few ohms (black or green). Mark them as R+ and R-. Just to be sure - repeat on the white and remaining wire. Mark them L+ and L-.

In the install I was stuck completing, there were additional wires in the room the wires came out for 2 more rear speakers for surround. I have to wonder if you have rear speakers in one of the rooms? That might be the second set of wires. All total, there were 4 sets of stereo speakers plus 1 set of surround speakers driven off a single receiver. A second room area had it's own set of wires for another receiver that was dedicated to that area.

If the last 2 paragraphs read like greek, you'll have to contact an installer on this one.

To answer your receiver question, you don't need much power - but you do want quality. You need to know more about what you have before selecting a receiver. In my case, the friend had a good Denon home theater receiver, so it had no trouble filling the house with wonderful sound.
