D-4.15 Amplifier-copy

D series D class digital power amplifier is specially designed to meet the sound reinforcement applications in theaters and performances. It weighs only 7.0kg. D series power amplifiers are based on Italian Powersoft digital technology and are equipped with ultra-efficient and reliable switching power supplies. Correction (PFC) function. The whole chassis is made of all-aluminum plate, which completely solves the heat dissipation problem. The electric capacity made of imported materials, small size and large capacity ensure that the power supply part is OK under any circumstances.

• Based on Italian Powersoft digital technology, D-PWM (Pulse Width Modulation) efficient output stage.
  
• Using the latest Class D technology, it provides smooth and flexible operation while maintaining superb power output, while maintaining excellent sound quality integrity.
  
• Stable performance is not limited by power supply, easy to operate (90V to 260Vac, 50 / 60Hz)
  
• To achieve full power output, no matter what voltage and load impedance the power amplifier is in, the power supply can be automatically adjusted by power factor correction.
  
• Ultra-large power, ultra-light weight, ultra-small size, all models are only 4.5kg.
  
• The circuit board uses 4 layers of circuit, 2A copper layout, 2mm thick, to ensure stable operation in any cruel conditions.
  
• Compact structure.
  
• Low noise variable speed fan.
  
• The best designed aluminum foil radiator.
