I want to create a multi room amplifier with multiple inputs, which is controlled by a micro controller (Microchip PIC32).
The amplifier will have 4 inputs and 6 outputs. On the inputs are TV's and radio's connected that are not amplified and the outputs go directly to speakers that are in the different rooms.
I did some research on the internet and found the following chips I think I can use:
TDA8650Q, because this amplifier only needs +14,4 volt and a GND
DS1802, because this one can be controlled easily by a micro controller
MAX4573, also because it is easily controlled by a micro controller
All these components only need a few extra components.
I made a small piece of the scheme and my question is:
Is this correct for 4 inputs and 1 pair of stereo speakers?
And is the signal (input) ground allowed like this?

An externally hosted image should be here but it was not working when we last tested it.
