Page 4: Speaker Outputs
The RS series amplifiers are intended to be fed from a mixer or mixer-amplifier signal output, providing additional power amplification for 100V speaker systems. The signal input should be connected to the SLAVE IN dual RCA connectors (12) on the rear panel. The RS series slave amplifiers are mono, so any stereo input signals will be summed together to provide a monaural output. -

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.
