I am looking to plan out a whole house audio system. The plan would be to have 3 rooms with TV's and an ATV3. Might get a ATV4 for the main room if the model works out.
Then have each room setup with a speaker or two in the ceiling that would airplay music through an airport express to some kind of amp. I guess controlling the amp would be the tricky part.
Has anyone seen anything like this before?
I have no idea if this is feasible, just trying to plan out how I might wire it all up as I am about to redo the ceilings and walls in almost the whole house.
I think what you are trying to do is quite doable. I decided to organize my house audio using Apple components and am satisfied streaming the same music to every area of my house. If you want to have different music playing in different areas of your house you need to use some other equipment such as Sonos. I didn’t want that and cannot provide you any insight but I’m sure others on this site can be very helpful if that interests you.
Here is a brief overview of what my setup entails. I am only describing what I have done and not trying to suggest this is what needs to be done. Glean from it any ideas that may be relevant to your desired setup. Consider the following just food for thought.
I generally use my main duty iMac for convenience. But, I am able to stream music from any one of my computers connected to my home LAN (I only have Apple computers; can’t comment on other platforms). Because my house has plaster walls with aluminum mesh reinforcement, wireless data transfer is not reliable and has been a PIA so I have run Cat5e wiring throughout my house with drops in each room (I recommend at least two for each room; also consider coax while you are at it.) and generally use ethernet for data transmission connections (e.g., computer to computer file transfers/Apple TV (video)), only relying on wireless for mobile devices.
I can stream music to any or all of seven locations in my house using a combination of Airport Express, Apple TV or AirPlay Speakers devices.
The Airport Express units (6 devices) and Apple TV (4 units) are connected to either various receivers (via analog) that I have accumulated over the years, a Griffin Twenty amplifier (via optical) and even two old portable stereos (one in the garage; the other which I bring out on my deck; both analog). The connected receivers and the Griffin Twenty have to be manually turned on and off but I don’t find that problematic. If you need speakers that turn on and off consider AirPlay ready speakers or receivers.
I have two Pioneer AirPlay speakers and a Pioneer Airplay Receiver (which have the benefit of automatically turning on when music is streamed and off via the streaming app) all connected to my LAN via Cat5e which play music that I stream from iTunes or my preferred application AirFoil (Rogue Amoeba).
I prefer AirFoil because it can stream to IOS mobile devices and Apple computers on my LAN using its included AirSpeaker companion OSX and IOS apps. My old iPod Touch (gen3) and iPhone 4 devices come in handy when connected to a bedside iPhone dock or a portable speaker dock used on my deck, for example.
I hope you find some of my description helpful. As I said consider it just food for thought. I found the effort to setup the ability to stream music throughout my house a very satisfying project. Good Luck!
