Audiocenter PD600 2U 3600W 4-Channel Power Amplifier

Audiocenter PD600 2U 3600W 4-Channel Power Amplifier
Providing a professional solution with high technology, premium sound performance and comprehensive protection systems, the Audiocenter PD600 Power Amplifier provides 4x 900W at 4ohm stereo, great for installations and performances. Class H circuitry.

Dynamic Sound
The detailed Class H circtuiry provides conversion of low power track to high power track in microseconds, ensuring accurate output power without excessive loss. It provides clear high frequency with rich tone, and warm and round mid frequency full of vocal charm, as well as a steady and powerful bass.

VL Crossover Circuit Design
The VL crossover circuit 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 a phase switch. It is therefore a great choice for subwoofer. 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.

Protection Systems
The Advanced Linear Limiter Protection Circuit reduces the gain appropriately while maintaining sound quality integrity, protecting the speaker while ensuring the audience experience is not affected, avoiding distortion or downtime. There is Soft-start Protection to Prevent Current Impact. The DC Protection effectively protects 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. The Short-circuit Protection effectively protects 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. 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.

PD Series 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. All components have undergone rigorous testing before assembly. Each power amplifier is tested thoroughly by the precise audio test equipment before shipment. The PD series power amplifiers can operate continuously with long-term stability. It is widely used in bars, nightclubs, multi function halls, museums, religious places, speeches, weddings and other fixed installation and mobile performance venues.
