I don't think every class-d type audio amplifier is with the same input amplitude.
If you explain more clearer,many peple may help you.

You can design for whatever level the equipment you want to connect to the amp puts out.

Line level outputs on CD players are typically about 4 volts peak-peak maximum. Headphone output depends on the volume control and varys considerably.
