Bosch Plena LBB1930/20 - Internal Fuse Settings

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