Help with some calculations

Hello everyone!

So since im not expierienced and im a little confused with some calculations i would like some help from someone expierienced. So im using the pt2314 audio proccessor and i want to calculate the max gain of the input signal to the power amplifiers.

So this is the datasheet of the part.

The max Input gain at 11.25 DB i got about 3.65 gain (Correct me if im wrong). So that means my max output amplification will be 3.65 times? Also at the volume control i dont really understand what the min/max attenuation rating is so if someone can help would be apreciated.

Moving on at the Max input signal handling at 2Vrms i got Vpk at 2.8 so that means that my maximum input signal i can handle is at 2.8 Vpeak? And if so i could get a Vo 2.8 * 3.65 at maximum gain?
