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 12.
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.

Rated 3 out of 5 by from Didn't seem powerful enough, but maybe enough for someI tried this out to replace an internally humming amp in an older AudioSource SW-4 powered sub from the mid 90's.This amp works fine, almost as expected. At the same time, I wanted to replace the older 12" driver with something more modern, as the 6Db boost made the older driver sound a bit muddy. I went with the Infinity 4 Ohm 12" 1260w after very good reviews of that driver. This amp did not seem to drive the 1260w as much as I had hoped. I have an optimal enclosure sealed and polyfill, but just did not deliver. I returned it and ordered the 300W model Yung plate amp with no boost this time, - in hopes it will deliver the experiece closer to what I am looking for.

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

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?

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.

What is the Q of the 35Hz boost and the order (dB/octave) of the lowpass filter?

Asked by: DanP
The manufacturer typically does not include this spec. Given .707 is flat, and .5 is -3db, you can make a reasonable assumption that the Q for +6db is in the area of 1.2
