Sony HiFi RV22 - STK 403-130 Question

Hi Members

I am new here and I have a few questions regarding the Sony HiFi RV22 - STK 403-130.

I am going to run this Amp separately and I wanted to know about feeding Input voltages, I have attached AMP schematic view.

Numbers Marked Red
1 - What voltage should I input for running 3 number Relay and where from I get that voltage.

2 - How much voltage should I input to mute the sound?
