I have a new Sony Home Theater Amp/Receiver (HDMI, etc.). There is an LED display that indicates the volume level. When you power up the amp it indicates -30db. 0 db is quite loud. What is it that I do not understand about dbs?

Furthermore, have you noticed that the manuals that come with these things do a very poor job of explaining what the various features actually do? They show conventional hookups, and how to access various features, but not why. In fact, if not for a blurb on the box label I would not have understood one of the really cool features of the system. Maybe it's just me...
