Mark, check page 78 in the 3805's manual. The second item down is "D.Comp (Dynamic Range Compression)
D.COMP. (Dynamic Range Compression):
Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). (This only works when playing program sources recorded in Dolby Digital or DTS.) Select one of the four parameters (“OFF”, “LOW”, “MID” (middle) or “HI” (high)). Set to OFF for normal listening.
TADA!
