INPUT
These 3 pin XLR sockets accept the source input for each channel. One input is a male XLR, the other is a female XLR. The
male XLR is normally used as a thru output. When wiring from unbalanced sources, pins 1 and 3 should be shorted together.
The input sensitivity (voltage required to drive amplifier to maximum power) of the amplifier is 150mV with the Input Level
Control set at maximum.
LEVEL
This potentiometer controls the level of the signal through the amplifier channel. Minimum position is Off and maximum gives
a sensitivity of 150mV. The input level control should be run above the 12 o’clock position (half way) to avoid clipping the input
stage.
SPEAKER OUTPUT
Speaker connections are provided on screw terminals. 4Ω low impedance and 100V.
IMPORTANT: If you are using the 100V output you must connect the jumper link between 4Ω and OT-IN

LOW IMPEDANCE OUTPUT
4Ω
NOTE: Only connect one output – either 4Ω or 100V. Do not connect 4Ω and 100V at the same time.
IEC MAINS INPUT SOCKET
This is a standard IEC 60320-C14 socket. It accepts a standard IEC mains cable, provided. The fuse drawer contains the
mains fuse and a spare. Consult the specification section for fuse ratings.
Always replace the fuse with one of the same value and type. Always disconnect power to the amplifier before replacing fuses.
