Howdy.

Well, I've read various articles online, but I find the answers to be confusing/vague/incomplete.

I'm trying to understand how my receiver "knows" it won't clip if I turn it up to 0db (assuming no EQ or calibration. I'm just running things straight).

I don't plan on running it this loud, but it would give me more peace of mind to understand this topic me thinks. For instance, some music is very compressed (runs hot). Movies can have large swings in SPL. How does my receiver (Yamaha Aventage) "know" that it won't clip if I set the volume to 0db?

And, if it is set to +1 db, does this mean it will most likely clip while watching a movie?
If set to -1db, is it possible for this volume setting to clip, depending on the source?

I've looked in the manual, but I couldn't find an explanation of this. Could someone help me understand this? (No hurry though.)

Thanks!
