Rolls RA2100B

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.
