China Audio Factory 500W Class D HiFi Super Bass Digital Subwoofer Plate Amplifier
Brief Introduction:
VISTRON AUDIO DSA Series Class D subwoofer power amplifiers are equipped with the unique ability to operate continuously at full rated output—a performance attribute not shared by most home audio amp designs. The benefits of this remarkable reserve capacity include solid, punchy dynamic range and fewer "nuisance" shutdowns when operated at sustained high levels. This subwoofer amplifier technology was developed to offer extreme amounts of power without the wasted heat and energy of traditional amplifier designs .A bass boost option enables the 12 dB/octave low-pass crossover, perfect for sealed enclosures and even certain vented box alignments.
The amplifiers are also extremely compact, lightweight, and cool-running, allowing users to enjoy the advantages of compact system form factors and flexibility of placement. An internal peak limiting circuit prevents amplifier overload, and protection against internal and external faults is also provided. Input power requirements are user configurable to either 110 VAC or 230 VAC line voltage.
Room optimization and system integration are accomplished easily, thanks to the DSA Series amps' inclusion of fully variable level, crossover frequency, and phase controls. Signal input is connected via dual RCA-type jacks, including the means to accept the output of an A/V receiver's LFE output, and dual RCA jacks are also provided to facilitate line level loop-through. When in standby mode, the subwoofer plate amplifier full active operation is engaged by signal presence of less than 0.5 watt.
