POWER SUPPLY
The amplifier operates on 230V AC or 24V DC primarily for battery backup operation. Ensure power is switched OFF at
the front panel before connecting either mains power to the IEC socket or 24V DC to the screw terminal input. As high
currents may be drawn when operating from a 24V DC supply confirm the capacity of the DC power supply used.

Audio input is via 3 pin balanced XLR sockets with input sensitivities of 300mV. Pinout details are printed on the rear of
the amplifier. The amplifier output level controls are rear mounted to prevent tampering or accidental adjustment.
