Audiocenter PD1000 Professional Four-Channel Power Amplifier

Description Introduction 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 PD1000 power ranging 400~1000W (8Ω RMS stereo), suitable for professional entertainers with limited budgets but demanding the best performance. Features Comprehensive Protection System Beautiful, dynamic sound Class H system Unique VLTM crossover circuit design Efficient cooling system Long-term stability Low cost High performance It is widely used in Bars, Nightclubs, Multi Function Halls, Museums, Religious Places, Speeches, Weddings. Plus 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. Low cost high performance The PD series power amplifiers have high cost performance that is difficult to be surpassed by other suppliers.
