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