Rolls RA200

Stereo Power Amplifier


The Rolls RA200 power amplifier features two 100 watt RMS - 4 ohm outputs, a bridging switch, MOSFET drivers in a voltage and current gain circuit, one second power-up delay, and LED power output meters. The unit is housed in a painted steel chassis and includes a special high performance transformer, and a fused power line. The MOSFET output stage is fault protected which allows the RA200 to forgive momentary output shorts, and has over-temperature protection.

The RA200 is convection cooled. Adequate ventilation room for the heat sink fins on the rear panel must be provided.
