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.
In power supply investing to Mute an output in, It becomes setting like the following. Input selector = ALL
OFF, Outside surround mode setting, REC-A,B SW=OFF,B1 main volume= - ∞ setting. The similar MUTE
setting can be done by setting D34=D54=1.
It is impossible to use the vocal cut and the inside surround function, First. it sets the vocal cut ON after
setting the inside surround ON, in case of switching to the vocal cut ON setting from the inside surround
ON setting. And it sets the inside surround ON after setting the vocal cut On, in case of switching to the
inside surround ON setting from the vocal cut ON setting.
