The output voltage of the priority controlled loudspeaker outputs can be set to 70 V or 100 V. To this end, 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.
Caution
Never insert two fuses into F701 and F702 simultaneously.
