R150+/R300+/R500+ : Reference Series Low Impedance Amplifiers
The R-PLUS Series are a dual-channel, high-performance amplifiers. Their clear, open sound and quiet operation make them ideal for reference systems and church sound applications. Inputs are via balanced XLR or 1/4” connectors, outputs are via rugged five-way binding post connectors.
All units have soft-start protection circuitry and feature signal, protection and clip indicators on the front panel. For added versatility, they may be operated in stereo, dual mono or bridged mono mode.
They have front panel mounted mains switch, level controls and indicators for power, protection, clip and signal present. Convection-cooling provides noise-free ventilation for critical applications. Mains inlet is via an iec connector. The R-PLUS Series amplifiers are powered by 100-120VAC or 220-240VAC 50/60Hz(depending on country requirements) and are packaged in a 3.5” (2RU) rack mount enclosures.
