AMP MODE SELECTOR SWITCH: This selects the functions of the two
power amp modules within the unit, whether bridged together as one mono
amp (set switch to ‘Bridge’), running in dual mono mode, as two separate
front-of-house amps (set switch to ‘Main-Main’), or running as two
independent amps, one for the front-of-house mix, and one for the monitors
(set switch to ‘Main-Mon’).

PHANTOM POWER: 48V phantom power, provided for condenser mics. and
active DI boxes. It is globally switched to all of the mic. inputs, when the
switch is set to ‘48V’. It is vital to ensure that phantom power is switched ‘Off’
when using passive mics., DI boxes, etc., in the mic. inputs, otherwise the
source may be damaged. All connections should be made before switching
phantom power on.
