Product Details

Yung SD200-6 200W Class D Subwoofer Plate Amplifier Module with 6 dB at 35 Hz

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. 6 dB bass boost centered at 35 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 signal presence of less than 1/2 watt.

Specifications: • Measured power output: 200 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 • Bass boost: 6 dB @ 35 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: 8" W x 7" H x 2-1/4" D; Cutout dimensions: 7-1/4" W x 6-1/4" H.

Yung SD200-6 200W Class D Subwoofer Plate Amplifier Module with 6 dB at 35 Hz
Yung SD200-6 200W Class D Subwoofer Plate Amplifier Module with 6 dB at 35 Hz is rated 4.0 out of 5 by 13.
Rated 4 out of 5 by from My fourth review of a Yung ampI am a retired audio writer (four books, over 150 magazine articles) and I have recently built three cylinder-style subwoofers to sell. Prior to this, I have built four other cylinder jobs, using Dayton 12-inch Reference drivers that I use in pairs in my two audio and AV systems at home, all powered by two Crown XLS1000 power amps, also purchased from PE. I have previously written reviews of the sub drivers on the PE site.The first amp I chose to use with one of the for-sale models was the SD300, and rather than install it in a sub enclosure (tricky to do with cylinder designs, although SVS has done it) I installed it in small outboard enclosure that allowed it to be stashed away, possibly clear out of sight. The second unit was an SD200 (the difference in output between 200 watts and 300 watts really is not much in acoustic terms) and it was handled much as I did with the SD300. The third was an SD200-6, and, unfortunately, it self destructed right after turn on. It was returned for no-hassle credit and I replaced it with another SD200, again installing it an outboard enclosure. Previously, I gave the SD-300 and SD200 stellar reviews. However, after additional evaluating I have to offer up some footnotes and downgrade the ratings by one star. Some points:1. After much checking I determined that the outputs from all three amps were phase reversed. That is, I got the best (smoothest) dovetails at the receiver-controlled LFE 80-Hz crossover points with the phase control at 180 degrees. This happened with all three subs that I built, and with the satellite speakers in both of my audio rigs, as well as the pairs that I built for use with those systems. This artifact did not show up with my Crown XLS amps. My solution was to wire the binding posts on the enclosures I built backwards, so that the phase is proper with the zero-degree settings. Phase is often no big deal, anyway, and the suckout nulls were only a couple of dB. Room-acoustic artifacts can easily nullify any negative artifacts that show up at the crossover points with subwoofers.2. The amps are not flat down to 20 Hz when measuring with the on-board low-pass filter set to 200 Hz. They are fine down to 30 Hz, but roll off by about 3 dB as the output extends downward towards 20 Hz. This is almost like the contouring we had with the original THX mandated subwoofer performance some years ago and generally will be compensated for by room gain fairly well. I am not sure if Yung did the rolloff to protect woofer drivers or had some other motivation, like a belated adherence to that now defunct THX standard, but it does exist in all three units. The three subs I built for sale themselves vary in terms of their acoustic rolloffs from about 35 Hz down to 25 Hz, and the amps tend to augment this rolloff.3. These are small amps, and their ability to put out serious power from small packages is one of their advantages. I suppose that if one were installing them in an existing sub enclosure as a replacement they might have to built a template to accommodate the smaller size (compared to the amp being replaced), but with a built-from-scratch model the small sizes allow for the sub itself to be built smaller than average. The amps also never get more than warm to the touch.4. Two of the subs I built for sale use 4-ohm drivers (one is a 12-inch Dayton Titanic, purchased from PE), but one uses dual series-wired 4-ohm units (built mainly for use in the classic Allison CD-8 full-range model) and the SD200 can probably only put 120 watts or so into that kind of load. Nevertheless, in my 3400 cubic foot main room that little amp and the sub could really rattle the walls. It often amazes me how loud 100 or so watts can sound with a subwoofer, even with drivers having only 87 dB or so of sensitivity.Anyway, I do recommend the SD200 (and the SD300, too), but the buyer does have to take into considerations their limitations.Howard Ferstler

Rated 4 out of 5 by from Only have had it briefly, but so far so good.The plate amp in a 10+ year old BIC V1015 sub went out; this review is more about compatibility with that particular sub than of the amp itself.*One specific comment about the packaging is that the documentation this amp comes with is more of a technical datasheet and not instructions/manual. This isn't a criticism considering who's likely to be looking for this type of product. Just an FYI for the uninitiated to not expect help from the included documentation.It is not an exact replacement for the original amp, but near enough.--Specs are compatible with the published specs of the BIC V-1015, no high-level inputs but I was using LFE anyway. The dimensions of the plate aren't quite the same, but a few minutes with a router to make the _original_ hole in the enclosure a bit bigger on one edge and you almost can't tell it's not the original amp from looking at it. (I suppose you could just use a jig saw and not worry about the recessed mounting lip if you don't have a router handy. It may not make an "air tight" seal in that case. But as the enclosure is already ported I can't imagine it would make a functional difference.)As far as sound quality and performance, it is as good or better than I expected. (I The weak link sounds to be the woofer itself, and not the amp.)On a related note--while this amp does work quite well with BIC V1015. I would be remiss if I didn't mention my ulterior motives. I repaired the sub as a birthday gift to my father. The real gift was taking something broken of his and making it like new.As far a quantifiable value goes... The BIC V1015 may not be worth a replacement amp of this cost. I've heard $150-200 subs that sound better than this setup (again the weak link does NOT sound to be the amp.) I also suspect that a decent 100W @ 4ohm amp would power this particular sub just as well, if you like fixing things.For what it's worth, I feel comfortable calling myself an audiophile/enthusiast around most people. But I'd be laughed out of a room of real experts.*Since it's required to give one, I'm going with a 4-star rating because 1) The amp has performed "good" in my setup. And more importantly because of the focus of this review, 2) at the time of writing, it is the average rating.Final note: When researching I found that the "replacement" model for the BIC V-1015, the V-1020, may look similar from the outside. But it is a completely different internally, so this review is not relevant to the V1020.

Rated 3 out of 5 by from Worked well for a year until a capacitor blewI purchased this in February of 2013 and used it to drive a small tactile transducer in my home theater. It worked well, and I had it driving around 60% output. I probably had 150 hours on the amp when a small capacitor blew, but everything is covered in potting compound, so I cannot replace the $1 part to repair the amp. It is now a brick, and the 1 year warranty is out. I would not recommend a Yung amplifier.

Rated 5 out of 5 by from Warranty ServiceI bought this product early in 2013 and stopped working in November. I shipped it back to Parts Express in early December after obtaining a RMA after calling them. It was really fast service (about a week) to get the new one by UPS. I shipped it by Fed-ex. Installed it the next day and plays great.

Rated 5 out of 5 by from Yung SD 200 plate ampI had a JBL PB12 with a bad amp. I called Parts Express and their tech and sales staff were very helpful. I ordered the amp, cut a new hole in the cabinet with a jig saw and screwed the plate amp on - it could not have been easier. I just left the old amp in place and cut off the power cord - and located the new amp on the other side of the cabinet to avoid the port and baffle.The order came timely and the product works great. I love it when things work out like that! The sub sounds better than it did with the original amp and there seems to be plenty of power - no popping noise when you turn it on like the old amp. I have heard that the early JBL subs often had problems with the plate amps, so if you have one (or even if you can find one cheap on ebay) for about $100 you can replace the amp and have a powerful sub.

Rated 4 out of 5 by from replacement unitI needed to replace a klipsch 12 amp that went bad. This unitworks very well and so far is doing a great job. I had to modify the box for a fit as it is a little shorter than the klipsch.

I understand with slight modifications to the cabinet, this unit works well in an Infinity BU-10 sub-woofer...Do you know if this is true?

Asked by: Poolboy2120
We do not have a direct cross reference available for this type of thing. As long as the original woofer is 4 ohm or higher this amp should work without issue.

Hi, I just installed this unit and it works great. I then blew a fuse on it and replaced it with the same fuse but the new fuse keeps blowing even when no signal is sent to it. I assume the reason for the fuse is to prevent damage to the unit.

Will this amp drive these speakers Bravox PXW12D-2 12" DVC Subwoofer 2 Ohm Per Coil and if so should they be wired in serial or parallel? Just one speaker for home.

Asked by: AlaskanGreg
Yes that amp will work well with that woofer. You will want to wire the coils in series for a 4ohm load.

What is the slope of the adjustable crossover?

Asked by: Pete B.
12 db per octave. Every filter you could ask for as well! Plus 110v & 230v switch--phase adjustment as well.

Is it possible to connect 2 drivers to the output ?

I need a replacement for a faulty amp on a Pioneer S-W200. It runs 2 x 6" inch Pioneer Linear Power Technology woofers, so I need to know how to eventually connect them to this amp, either in series or in parallel (if it´s even possible to run both together).Thanks for your help !
Asked by: ChrisCvitanic
As long as the woofers each have an impedance of 8 ohms you can connect two to this amplifier.
