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 CONNECTIONS
Audio input is via 3 pin XLR sockets on the rear of the amplifier. These are 500mV line level balanced signal which are
normally fed from a mixer panel. Pinout details are printed on the rear of the amplifier. Balanced Line Out XLR sockets are
also provided on the rear of the amplifer for passing the audio signal on to more slave amplifiers if required. The
amplifier output level controls are also rear mounted to prevent tampering or accidental adjustment.
