Description

Details

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.
