Rolls RA2100b 2-Channel 100 Watts/RMS Channel @ 4 Ohms Power Amplifier

The Rolls RA2100b is a stereo 100W/channel RMS power amplifier in a standard 2 rack space format. It is intended for professional audio and distributed musical applications. The unit features 100 Watts per channel RMS into four ohms, 85 Watts per channel into eight ohms, and for the contractor – 70 Volts / eight ohms. The unit also features MOSFET drivers in a voltage and current gain circuit and a one-second input turn-on delay. The RA2100b will drive 25 Volt speaker lines directly from each channel, or 70 Volt lines bridged. The 2100b is convection cooled. Adequate ventilation room for the heat sink fins on the rear panel must be provided for.
