Default Guidance for a 120W mono 100V audio amplifer

Hi All

This is my first post here, I am starting my first Audio Amplifier project and I need Help to get started. I have looked arround many sites including Texas instruments to get started but there is so much stuff that gets me confused.

I want help in designing the an amplifier with following features.

- upto 120W
- 3 input chans
- Mono
- output audio should be 100V
- digital gain and volume control (i need to be able to control the volume digitaly )

I would be using it power a max of 40 speakers around in the villa ( 3Wx40=120W)

I prefer Texas instruments products as i can get samples free but I am open to any brand you guys will suggest.
I also am ready to buy any development or eval kits that will Help.

please Guide me how should i start , I need to understand the basics , and guidance for which type of amplifier and other blocks should i use.

Thanks in advance
