Product Details

Yung SD500 500W Class D Subwoofer Plate Amplifier Module No Boost

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.

Specifications: • Measured power output: 500 watts RMS into 4 ohms @ < 1.0% THD • Signal to noise ratio (at rated power): >90 dB • Input sensitivity (@ low level): 210 mV/50 Hz • Input sensitivity (@ high level): 3.0V/50 Hz • Low pass adjustment: 40 Hz to 200 Hz • Phase adjustment: Continuously variable from 0º (normal) to 180º (reverse) • Power requirements: Switchable, 115/230 VAC, 50/60 Hz • Dimensions: 9-7/8" W x 10-5/8" H x 3" D; Cutout dimensions: 8-7/8" W x 9-3/4" H.

Rated 5 out of 5 by from Very good ampI had an spa240 and it worked good for 2 years and then it died got this to replace it and this makes my 2 12" in a dcm sub 2 pound don't be scared to buy this so far very impressed

Rated 3 out of 5 by from Intermittent hum and pops when shuts offFirst few days were good. The amp sounds great, I like it better than the previous 500 W BASH but still, there is hum at idle and the thing POPS quite loudly when the auto circuit shuts it off. Annoying and potentially damaging.The hum comes and goes when I moved it a few inches. Not indicative of good quality. Maybe it's cables, still need to verify.

Rated 5 out of 5 by from Built well, performs greatFrom the weight of it, (especially compared to what it replaced for me) I could immediately tell it was good quality. It's running 2 12's in a large party room and while it gets warm after a couple hours of serious abuse, it doesn't miss a beat, distort, or otherwise complain. Major bang for the buck.

Rated 5 out of 5 by from nice valueBought 2 of these on sale to power the sub portion of my towers. Nice amp for the money well made provides plenty of power. Little on the large side would be nice if it was a bit narrower. Can't complain since most comparable sub amps are similar in size. Don't hesitate to pick one up, and if it’s on sale get it quick because they sell out fast.

Rated 5 out of 5 by from Solid performerBought two of these units for two subs I just put together using 12" 4 ohm drivers. The amps have solid low bass capability and run pretty cool. No hum or noise problems at all. My only wish is that the auto turn on feature could either be disabled or had a lower input threshold to turn on. I sometimes have to give it a good volume shot to kick them in. Seem like they are pretty well built units.

Yung SD500 500W Class D Subwoofer Plate Amplifier Module No Boost

I bought one and this is a good product but the documentation is poor. Question: Are the outputs (either the line level or the high level outputs) high pass to the amplifier or satellite speakers?  Is there a crossover network on the outputs?

Asked by: farthings

Asked by: pakji
This amp will produce roughly 250 watts RMS into 8 ohms so this will work with that subwoofer.

I would like to build a powered sub for a small PA for a RnB band. I have some free Infinity car subs (12s) wondered if it is worth the endeavor or possibly the duty cycle of a music reinforcement system is too great for a home amp.

Asked by: MikeR1959
We do not recommend using any of our subwoofer plate amplifiers for this application.
