rkeman brought up some good points. I would add these:

I think -15db which I assume is a volume control setting means 15db below the rated gain/ output of your preamp. We can't put a number on that because the source output level and impedance play a role. Then of course we are playing music too which is always varying in level.

You can plug your source into your power amp and you'll probably find that with today's hi out low z sources it will overdrive your power amp meaning your preamp is almost always attenuating the source. Be very careful if you do. I recommend a quiet passage of classical music if you do with thevremote in hand to be able to hit stop. (Using CD not vinyl or tuner) That's why I now use a passive line stage by the way.

Also I've seen preamps that have anywhere from 12-27 db gain and I'm sure the are others outside that range.
