Product Details

Yung SD500-6 500W Class D Subwoofer Plate Amplifier Module with 6 dB at 25 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. A bass boost option enables the addition of 6dB of EQ centered at 25 Hz, 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: 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 • Bass boost: 6 dB @ 25 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 SD500-6 500W Class D Subwoofer Plate Amplifier Module with 6 dB at 25 Hz is rated 4.3571 out of 5 by 14.
Rated 5 out of 5 by from Surprise!Ive been using this to drive some Dayton Audio reference series 10", 4 ohm subwoofers.After making some open baffle (dipole) speakers, I tried dipoling Celestion 15"ers, combined with Selenium compression drivers feeding 12" round waveguides. The 75 watt receiver on hand did a poor job on those Celestions .Next tried active crossovers with the BBE Max-x-3 pairing filtering 2 tube amps and one Yung plate amp.On a dipole baffle this amp can reach up to meet a 500 hertz crossover point.Surprise! It sounds very good.

Rated 4 out of 5 by from So far - So goodWell, I bought this amp to replace the O.E.M. LT/350 amplifier from Elemental Designs (now out of business). I needed to pick an amp that was a bit larger in cut-out so I could easily modify the enclosure. The amp looks like it is a solid build, and so far it plays just fine. The only negative I can give the amp, is that it produces a low freq hum. You can't really hear it until you are 3 or 4 feet away, but it is audible. (not when anything is playing obviously). Previous amp from ED had no such hum. You wouldn't expect a hum from am amp that costs this much.

Rated 5 out of 5 by from Quality & Operation excellent!I have been operating the Young SD500-6 for one monthI have been operating the Young SD500-6 for one monthQuality better then expected. All Parts are Glued In Place to Prevent damage from Excessive audio Vibrations. It has a removable Heavy Duty Power cord. The unit I received, has a Large aluminum heat sink on the Pre Driver Power Audio Transistors. The Main Power Out Put Driving Transistors are heat sinked to the Plate itself. The on board, Bass Boost , Cut & Freq controls work very good. The only issue I found is the Power Output transistors that are head sinked to the plate itself, are mounted near the audio pots (The Bass Boost, Cut & Freq Controls). This causes all the main heat to dissipate the majority of the heat near these controls, but so far it has not been an issue. The Entire Plate itself does get fairly warm while in use but not really hot. I have been operating the Plate Amp at mid power for 30 to 60 minute continuous intervals with a total on time of over 8 hours. The Plate Amp gets fairly warm to the touch but not hot. I have it mounted in a 2 foot cubed area, with out any fans for cooling. I have not tested it at full output. I’m using it in my home theater room to drive six 12” sub woofers. The Plate seems to operate better at higher impedances then lower, so if you’re connecting more then one speaker to the unit I would configure your connections to give higher load impedance then low load impedance that’s within the amp specifications. I know Amp power out decreases at higher impedance loads but the Plate stays cooler and seems to have less distortion. This is by ear only, I have not verified it with a Scope (Oscilloscope) to actually look at the distortion levels.Over All: Price Vs Power - I give it 5 starsSuggestion: I would put the unit into some type of metal electrical box to prevent any of the components from getting damaged or any one toughing it while in operation. Also I would add a fan to the side of the box to help move the air around the plate. I suggest a 220vac PC fan connected at 120vac. to reduce fan speed and fan noise. You only need to keep the air moving. If you put the Plate Amp into a sub woofer wooden box, the air movement from the sub would probable be enough to keep the unit cool.

Rated 1 out of 5 by from Unreliable, poor quality.I purchased this sub amp about 10 months ago, at the time around $US300. My brother built a sub box, extremely well built, with 2 x Vifa 10" drivers. I routed the rear of the box, so the Yung SD500-6 would fit neatly.It has worked fine for a few months, with the exception of the initial problem: with no devices connected, when i initially turned the SD500 amp on and it makes a noise that sounds like a repeating tweet sound. High pitch, repeated, volume does not change with volume controls on sub amp. This went away after some time.The problem today: When connected to my home theatre amp, nothing comes out. When connected to an RCA lead to phono plug, connected to my phone, nothing comes out. It has a LED power light on the back, but nothing seems to be working. Swapped out every cable, problem solved it to the best of my ability and it shows no signs of life, other than the LED power light.Due to freight costs, i'm left with a $300+ paper weight as there are no schematics or wiring diagrams available after the purchase.

Rated 5 out of 5 by from Great Plate AmplifierI purchased the Yung SD500-6 to pair with a sealed Dayton HO-15. This amplifier did not disappoint. It has plenty of power, and the boost really helps my sealed subwoofer reach down low for ground shaking bass during movies. I have a very large great room with a single 15" sub, and this amplifier provides more than enough power to fill my room with amazing bass.I have used Bash plate amplifiers in the past, and so far, the Yung amplifier is every bit as solid as the Bash amplifiers I have used in the past.

Hello I need a plate amp that will fit a cut out of 9x9 will this one work

Asked by: Martese
The cutout you have will require modifications. This amplifier needs a cutout that measures 8-7/8" W x 9-3/4" H.

Will it be ok to build a box with plywood to the right size and install it remotely to power the inwall subwoofer ?

Asked by: Bprreddy
Yes there would be nothing wrong with doing this.

Is this unit concealed ? Do I need to buy a case to mount ? What is the proper installation procedure ?

Asked by: Bprreddy
This amplifier is not enclosed, it is designed to be mounted into a powered subwoofer enclosure.

Can I use this to connect two subwoofers of 300W each at 8 ohms Acoustic Audio 10 inch HDS10. And how do I connect these ? parallel or Series?

Asked by: Bprreddy
Yes this will work for that application. You will have to wire them in parallel for a 4 ohm load.
Answered by: MattP
Date published: 2015-06-29

the spec sheet shows "Standby @ audio detection circuit load --- <0.5W". Does this mean that it will automatically go to standby when there is no music to play, and in standby it will consume less than 0.5 watt? The Dayton & Bash use 18 W standby.

Asked by: blakely
The Auto on/off feature generally is about 10 minutes to go off but once it senses the Audio it will turn on. The standby draw of the amp is less that .5 watt.
