The 1600 is one of the few DVD-A players to include bass management. You can select "Large" or "Small" for the speakers, delivering a 100 Hz low-pass summation of the five channels to the subwoofer when "Small" is selected. However, all five speakers are all still fed a full range audio spectrum. There is also a Delay Time setting for the center channel and rear surround channels, along with a channel balance control (volume) for the center and rear. It is nice to see this, since, as you are probably aware, you have to connect the multi-channel DVD-A outputs from the DVD-A player to your receiver using 6 analog cables. There is no digital output for DVD-A.
