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.
