Rolls RA200 规格指南

R A200 Power Amplifier

The RA200 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 RA200 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
