I just purchased a Yamaha RX-V1300 and the Epic 60 system. This is my first foray into home theater. I have a question regarding the decible (db) level display on the LCD panel of the Yammi. When the volume is turned all the way down, it displays 99db and when it's turned all the way up it displays 0db. This is counter to what I would have expected. How should I interpret this information? From what I have read, I beleive that the volume of sound doubles with an increase of a few dbs (every 4-5 db?). But in the this case it appears that the dbs are decreasing as the volume is turned up.

Any insights will be helpful. Thanks.
