- Class D amplifier circuit with switching power supply provides excellent efficiency
- Capable of sustained, continuous output without thermal shutdown
- Built-in limiter circuit protection prevents peak overloads
- Low-level, high level, and LFE inputs for flexible interconnection
- Manual and automatic on/off mode options
- 6 dB @ 30 Hz bass boost plus fully adjustable phase, gain, and crossover points
- Switchable 115/230V input voltage
Yung International’s SD Series Class D subwoofer power amplifiers are equipped with the unique ability to operate continuously at the 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. 6 dB of bass boost (centered at 30 Hz) makes this amplifier 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 115 VAC or 230 VAC line voltage.
Room optimization and system integration are accomplished easily, thanks to the SD 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 amp’s full active operation is engaged by a signal presence of less than 1/2 watt.
