Rolls RA200 User manual

R A200 Power Amplifier
The R A200 features two 100 watt RMS - 4 ohm out-
puts, 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 per-
formance transformer, and a fused power line. The
MOSFET output stage is fault protected which allows
the R A200 to forgive momentary output shorts, and
has over-temperature protection.
CAUTION: The R A200 is convection cooled. Ad-
equate ventilation room for the heat sink fins on the
rear panel must be provided.
FEATURES:
 MOSFET drivers in a voltage and current gain
circuit
 1 second turn-on delay
 LED power output meters
 Fault protected outputs
