Amplifier with 6 channels and bluetooth

[guilig]

Hello

I am newby and I want to build a digital amplifier (6*100w) with bluetooth receiver or optical receiver.
I plan to use TDA7498 for amplifier.
My question is how can I use a bluetooth receiver audio module and dispatch the audio stream on 4 or 6 channels ?

Is someone has schematic or advice to help in this project?

Thanks
