With the 525, you can have it both ways.
Option 1: When the 525 is in "6 Channel Direct" mode, there is no bass management occurring in the receiver. In this mode, the receiver merely amplifies whatever it is receiving, with no analog to digital conversion. Any unused input jacks are muted to prevent noise.
Option 2: When the 525 is in "6 Channel DVD Audio" mode, the receiver's triple bass management becomes active. For this to occur, the analog signal from the source is converted to digital. As with option 1, any unused input jacks are muted to prevent noise.
