- 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

Yung International's SD 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.
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. The amplifier also accepts high (or speaker) level input signals through binding post terminals. When in standby mode, the amp's full active operation is engaged by signal presence of less than 1/2 watt.

- Products with visible signs of use such as mounting marks*, scratches, solder, sealing caulk, dirt, sawdust or other debris/residue, extreme odors such as cigarette smoke
- Speakers with a burned voice coil are not returnable for exchange, repair, refund, or credit, as this is not covered by its warranty. No exceptions. Distinct burn odor and/or discolored/black spider around base of cone are characteristic of a burned voice coil. While we do not accept returns of speakers with burned voice coils, they may be returned, postage prepaid, for evaluation.

*AUDITIONING YOUR SPEAKERS
Each speaker order includes the following instructions: To "audition" a speaker without scratching or marking it will require getting into the speaker cabinet and listening to it play without actually mounting it with screws. This can be done by tilting the cabinet back and setting the speaker in place. If the cabinet has bare wire leads, just wrap them around the solder lug connector on the back of the speaker to make the electrical connections. A friend can help hold the speaker in place while you listen to the new speaker. This is, of course, not an optimal way to listen to a speaker, but will give you the opportunity to identify major response problems or poor tonal characteristics prior to mounting.
