Surround of outside setting, It becomes"D54=1"--->SW41 and 42 setting = B fixation.Surround of inside setting (Surround of outside non setting), It becomes "D54=0--->SW41 and 42 setting = A fixation,It becomes volume input selector A setting = A fixation. In power supply investing to Mute an output pin,it becomes setting like the following.Input selector = ALL OFF,Outside surround mode setting,REC-A~C SW=OFF,B1 main volume=-∞ setting.The similar MUTE setting can be done by setting D34=D54=1 to DC=DD=1,DE=DF=0.
