RA200 : 100 Watt Power Amplifier Power Amplifier 100 watt RMS - 4 ohm outputs และ bridging ใช้ MOSFET เป็นวงจรขยายภาค output มีวงจรป้องกันภาค output เพื่อป้องกันลำโพงไม่ให้เกิดความเสียหาย ใช้ MOSFET เป็นวงจรขยายภาค output 1 second turn-on delay. LED แสดงระดับสัญญาณ output มีวงจรป้องกันภาค output 100 Watts RMS per Output (4 Ohm) 85 Watts RMS per Output (8 Ohm) 200 Watts RMS per bridged (4 Ohm)     The RA200 features two 100 watt RMS - 4 ohm outputs, 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 performance transformer, and a fused power line. The MOSFET output stage is fault protected which allows the RA200 to forgive momentary output shorts, and has over-temperature protection. CAUTION: The RA200 is convection cooled. Adequate ventilation room for the heat sink fins on the rear panel must be provided.   RA200 : 100 Watt Power Amplifier MOSFET drivers in a voltage and current gain circuit. 1 second turn-on delay. LED clip indicators for each channel. Fault protected outputs.
