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.

Yung SD500 500W Class D Subwoofer Plate Amplifier Module No Boost
Yung SD500 500W Class D Subwoofer Plate Amplifier Module No Boost is rated 4.625 out of 5 by 8.
Rated 4 out of 5 by from So far, so goodI have had this amp only for a couple of weeks. It's driving a Dayton Ultimax 15. It sounds great. Drives the Ultimax effortlessly.When run hard, the surface of the amp is a little warmer -- maybe a bit warmer than I expected out of a class D. Minimal speaker hum. Unnoticable unless you put your ear directly to the speaker. Amp adjustments are great. I do wish it had an adjustable low pass filter, but so far the speaker is performing just fine without it. No complaints as of now.

Rated 5 out of 5 by from Tested with music and theater, results; impressed!Setup:2 of these no-boost amps (most home theater/AV receivers have sub/LFE adjustments anyways).2 dual-4 ohm voice coil subs run in series for an 8 ohm load.Open air enclosure in the basement.Been using it now for little over a month, and other than a few things falling off the wall, my impressions are nothing but solid! Inspecting the insides, you can tell they were looking to make this last! So many aspects of the design (visually) show they addressed all the areas that would ensure long term reliability. Though I installed this in an open-vented location (instead of sealed in a sub-box), there was care in making sure the heat generating chips would have adequate cooling ability. Upon running it hard for a time, I only found the outside of the case getting warm, nothing inside got that warm. This proves they knew it would be in an enclosed environment where there would be no real air-exchange inside. So the biggest dissipaters of heat would be able to conduct through the outside of the case, very nice, must be someone used this at home and decided what would actually be best, instead of waiting for negative feedback telling them they did not do their testing properly, ending with their reputation suffer even more from that. I was stuck with two dual-4 ohm voice coil subs leftover from my last setup, but found that with 2 of these amps running 8 ohms worked quite well (two 4 ohm coils run in series to make 8 in this setup, since two 4 ohms run parallel would make 2 ohms, that this amp won’t do, fine by me). Bass is tight, fluid and musical on songs, as very powerful and gut wrenching for home theater awe! Adjustments are the ones you want, and work as promised.Only thing I can add is it would be nice to include screws to mount it, not a big deal though, just plan ahead to keep the excitement going once you get it and want to put it onto action. Remote control over-ride for late night movie viewing would be a fancy feature request, run from an app off your phone of course, though you can get a 15 amp-rated wireless remote control device for the plug outlet easy enough to silence these at night, I have 2 (1 for each amp ;-).A very good piece of gear!

(2) 8 ohm cabinets- follow-up for MattP

"You will have to put an output jack on the cab with the amp and run the second cab from that jack."-- MattPMatt, do you have a recommendation on the best way to do that?
Asked by: Bongo Dave
There are many ways to do this. The easiest would probably be a set of standard binding posts wired in parallel to the woofer in the cabinet with the amplifier and a similar set of binding posts in the passive cabinet. Run standard speaker wire between the two.

How do I use this to power a second 8 ohm cabinet?

I want to use this to power (2) 8 ohm subs in a PA application. How do I daisy chain the second cab?
Asked by: Bongo Dave
You will have to put an output jack on the cab with the amp and run the second cab from that jack.

Connecting to a receiver without LFE output?

For a receiver without LFE output, I'd have to connect the speaker outputs of my receiver to my main speakers, then run the same connections to the "Speaker Level In" of the Yung, correct? Thanks.
Asked by: hongrn
Yep that will do it.

How much volume does this amp displace?

How many L / ft^3 does this amp take away from the overall volume of the enclosure it's installed in?
Asked by: Stereodude
Dimensions: 9-7/8" W x 10-5/8" H x 3" D; Cutout dimensions: 8-7/8" W x 9-3/4" H. These are the numbers you use to calculate the volume of air displaced by the amp.

2 Ohm Load

Will this amp be safe to power a pair of speakers that are put in parallel, to make a 2 ohm load, safely?
Asked by: Paul T
Unfortunately no, all of our subwoofer plate amplifiers are design for nothing more than a 4 ohm load.

No boost vs boost?

What is the benefit or correct application when discussion boost vs no boost in the Yung amps? I have a ported RSS390HO tuned to 21 Hz used for HT and I’am confused if boost will help or hurt my application.
Asked by: WoodCock
We recommend the boost model for sealed subs to help with the low end. We do not recommend them for vented subs because the boost can hurt the woofer and give you a bit of an overwhelming sound near the tuning frequency.

What about an 8 ohm load?

There's no power rating into 8 ohms. Does this type of amp need a 4 ohm load to work?
Asked by: Flint
This amp has more than enough power to drive an 8 ohm speaker to deafeningly high levels. It will drive your speaker to more than adequite levels. It would just rate at a lower power level.
