Multizone amps with more than two input sources

[addigz6]

I want to play music in my house and i have 12 zones - I want to use 12 google audio chromecasts as inputs so I can play different music simultaneously in more than one room - the multizone amplifiers that I see online have only 2 input sources which can play in multizones - I require multi inputs - any suggestions on an amp that works that is not super expensive?

Separate stereo amp + chromecast per zone?

Thanks for answering - The amp would be multizone so 1 amp but 12 chromecasts would control each zone

Most multichannel amps have separate inputs for each channel. They do usually have a switch that will allow all channels to run with a single pair of inputs.

You would need two to do 12 zones in stereo.
Since your phone is the source won't the battery go flat after a few hours of use?
Maybe an Echo Dot or Google Home Mini would be better since you only control them with your phone and they do the streaming.
