3.3 Internal setting
The output voltage of the priority controlled
loudspeaker outputs can be set to 70 V or 100 V. A high
power fuse inside the unit is used as a voltage selector.
Insert the high power fuse into fuse holder F701 for
100 V selection (default setting), or into fuse holder
F702 for 70 V selection. This selection does not affect
the output voltage of the loudspeaker direct outputs.
Refer to figure 3.3.
