Chances are if The Receiver only has sound in Stereo Direct Mode and all surround modes and Sub out are Inop the DSP (Digital Signal Processing) Card is most likey defective. These boards are not available from marantz (D&M Holdings) and must be Component level repaired which usually is not cheap. If Only the Sub out is not working check setup to be sure sub woofer is set for on. Also If On Screen setup menu does not appear on video monitor Unit may need to be Reset manually which entails discharging a Capaitor on main P.C.B Contact email@example.com for details

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

Subwoofer is center speaker from A+B speaker signals. first check your wire to the receiver. Otherwise you need electronics service on the amplifier inside the speaker.
