RA2100b Power
Amplifier
The RA2100b is an ideal installation amplifier for
small to medium sized applications. The unit is built
solid and housed in a painted steel chassis. It also
includes special high performance transformers and
a fused power line. The MOSFET output stage is
fault protected which allows the R2100b to forgive
momentary output shorts. It is designed to drive 4 or
8 Ohm speakers, 25V speakers (individual channels)
or 70V speakers (in bridged mode). CAUTION: The
2100b is convection cooled. Adequate ventilation
room for the heat sink fins on the rear panel must
be provided for.

FEATURES:

• Great install amp, drives 25V or 70V lines
directly.
• MOSFET drivers in a voltage and current gain
circuit
• 1 second turn-on delay
• LED power output meters
• Fault protected outputs
