3 [DC SW]
Resettable fuse. The fuse shuts down when the power amp's current drain is too high or when the loudspeaker
output is short-circuited. To reset, disconnect the connected speakers and turn the switch back on. If the switch trips
again, there is a defect.
4 [POWER INPUT]
IEC chassis plug for operating voltage supply with fuse holder. Before connecting to the power supply, check that the
voltage selector on the bottom of the unit is in the correct position.
Should the fuse have blown, disconnect the unit from the power supply and replace the fuse with a new fuse of the
same type.
5 [OUTPUT]
Loudspeaker output screw terminals The connectors are located under a removable cover. Replace this cover after
connecting the speakers and before you turn on the power.
6 [DC INPUT]
Screw terminals for the power supply with direct current (24 V), for example with an uninterrupted power supply. If
the mains voltage fails, the DC input is automatically engaged.
