PD Series

Professional Four-channel Power Amplifier

The PD series is a professional four-channel power amplifier with high technology, premium sound performance and comprehensive protection system. It is a truly high-quality professional power amplifier.

The PD series power amplifier includs four models (PD400, PD600, PD800, PD1000), power ranging 400~1000W (8Ω RMS stereo), suitable for professional entertainers with limited budgets but demanding the best performance. It is widely used in bars, nightclubs, multi function halls, museums, religious places, speeches, weddings and other fixed installation and mobile performance venues.

  • Comprehensive Protection System
  • Advanced Linear Limiter Protection Circuit
    Reduce the gain appropriately while maintaining sound quality integrity, protecting the speaker while ensuring the audience experience is not affected, avoiding distortion or downtime.
  • Soft-start Protection to Prevent Current Impact
  • DC Protection to Effectively Protect the Speakers
    When the output terminal of the power amplifier detects the DC voltage, the protection circuit will cut off the output to protect the speaker from damage, and in the meantime the protection light of the channel will light up.
  • Short-circuit Protection to Effectively Protect the Power Amplifier
    If the output is short-circuited (for example, a defective speaker or speaker cables are crossed), the short-circuit protection circuit will automatically protect the power amplifier. The power amplifier will not resume work until the short-circuit problem is solved.
  • Thermal Protection
    When the heatsink or transformer has abnormally high temperature, it will trigger the internal thermal protection of the power amplifier. The protected channel protection light will be on and the output of the channel will be turned off. Only when back to the normal temperature range, the protection channel will deliver output.
  • Beautiful, dynamic sound
  • Clear high frequency with rich tone
    Warm and round mid frequency, full of vocal charm
    Steady and powerful bass
  • Class H system
  • The Class H system makes the power amplifier realize the conversion of low power track to high power track in microseconds, ensuring accurate output power without excessive loss.
  • Unique VLTM crossover circuit design
  • VLTM crossover circuit, designed as 24dB/oct, is connected with filter, which not only provides a good drive and feedback effect, but also ensures low total power consumption. The crossover point is 6dB, no need for phase switch.,It is a good choice for subwoofer and small-sized sound system.
  • Efficient cooling system
  • The PD series power amplifier uses a stepless fan system, which guides air across the amplifier and draws cold air successively through the power transformer, fan and radiator. It is equipped with four fans to keep the transformer in a cool state.
  • Long-term stability
  • In order to ensure product quality, PD series amplifiers components are carefully selected by professional engineers and senior purchasers.
    All components have undergone rigorous testing before assembly. Each power amplifier is tested thoroughly by the precise audio test equipments before shipment. The PD series power amplifiers can operate continuously with long-term stability.
  • High cost performance
  • The PD series power amplifiers have high cost performance that is difficult to be surpassed by other suppliers. Welcome bulk purchase, we will provide support for all customers with the best quality.
