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
