Operation
When all connections to the amplifier are made, turn the MASTER volume control (1) fully down and
switch on the power (3) and the power LED will illuminate. Ensuring that the signal is active on the
SLAVE IN inputs, turn up the MASTER gradually to the maximum required volume level.
The output of the amplifier is represented on the SIGNAL LED and when the amplifier is running at
its peak output, a PEAK LED will illuminate. Care should be taken that the Red PEAK LED is only lit
momentarily during use. Anything longer than a short flash of this LED may be indicating distortion
or clipping of the output signal and the MASTER volume should be turned down.
