Thanks for watching! Have a nice day :)

Hello. In this video (kzfaq.info/get/bejne/kLyeeLRe36_KXXU.html), we demonstrated how to use 2pcs power supply to power the IRS2092 amplifier board. Wish this could help you. Have a great day~

Hello, the power supply range for this mono 1000W IRS2092 is ±55V - ±65V. If you want 1000W RMS into a 2Ohm load, ±63V would be required. Please note that the IRS2092 amplifier boards need dual power supply. So, you can use transformer and rectifier or two AC/DC power supplies for powering it up. Wish this could help you. Have a fantastic day~

Hi miguel. Thanks for your advice. We will pay attention next time. Have a nice day :)

Hi. You can find all these products on our online shop. Here is the link for your reference: store.sure-electronics.com/product/AA-AB31391.

Hi, John d. Thank you for your watching. This unit requires dual power supply. The standard product is not integrated with transformer. You need to buy the transformer and rectifier capacitor bank board to power this amplifier board. You can refer to the 'Connection' on the product page for reference. Have a nice day.

220 or 120. I have this rectifier board, using it with a transformer that takes two 120V AC inputs, and outputs two phase 40V AC. The rectifier takes these as its input, and then outputs -52V and +52V, measured against the 0V ground output--in other words the negative terminal is not ground, it's hot, just in opposite phase to the positive terminal. If you measure across the - and + terminals you'll see it's actually putting out over 100V DC total. The way they describe it is fairly confusing, as we normally always look at the "-" output as ground, but in this case, they're referencing 0v as ground. Took me a minute to figure out what was going on exactly myself.

Configuration is identical, just using a transformer that accepts 120V. Whether you're starting with 220 or 120 (or even 480), you just want a transformer that's outputting two AC phases of an appropriate voltage. In their example, two phase 48V AC.

@@jasengibson6619 i think you mean single phase 48vac from single secondary output side of transformer? I think the voltage input is single phase appropriate voltage. Some of their amplifiers can go higher voltage than 48 vdc. Some videos showing how voltage source 110vac through a transformer then rectifier would be helpful just to see it done correctly.

@@GonzoZener Nope, I mean two phase. Two AC inputs on the rectifier. I'm using this board with a transformer that takes two 120VAC inputs, and then outputs two 40VAC lines from the secondary in opposing phases. Whether the phase is important or not, I don't know, but it would make sense. The rectifier has two inputs, I have one phase to each. I assume the rectifier is essentially dividing the top and bottom of the sine wave of each input, then combining the upper half of both to one output (the +) and the bottom half of each to the other output (the -), then smoothing out the ripple with that bank of giant caps. So, when I measure across my output terminals, I get 61VDC from Gnd to +, -61V from Gnd to -, and 122V from - to +. So this rectifier puts out 120VDC total with two 40VAC inputs. And the amp they show in this video requires both of these power outputs---so they're speccing it fairly wrong. The documentation says 65-75V for input, but that's really X2. The amp I'm using it with is the 500W version of this, which wants two 55-65W power inputs, so I'm giving it both 61V outputs of the rectifier, which is really 120V when measured across them. This rectifier is a beast. The wiring is simple--the transformer has four input wires for the 120 coming in (hot and neutral), and four output wires from the secondary. Here's an image of the transformer-rectifier wiring: drive.google.com/file/d/1aTyBADrIWuWiHIT-nPY0DPhMrqv3gShk/view?usp=sharing

@@jasengibson6619 I get it. Just would like to to see this amplifier wired with a 120 VAC circuit which is the most available circuit in the USA. 240 single phase in USA is option too but odd for a home Class D amplifier application.

Hi, Anthony Fouracre. Thank you for your watching and kind suggestions. We will take your advice seriously and make improvements to provide high quality videos for you. Have a nice day.

Hi Eiliv， Please contact the customer service staff of the sales platform where you purchased this product , or send the connection video to my email address（ info@sure-electronics.com ）, I will provide you with the right solution.Thanks for your support.

Could you please kindly place orders in the new website? If there is still problems, feel free to contact us with store@sure-electronics.com.

Hi Edifier, Adhering to the concept of integrity management, the nominal power of WONDOM's products are all true RMS. Have a nice day.

@@WONDOMAudio If you're sure your amps can do rated power, you can throw in a power output test to gain credibility.

WONDOM AA-AB31391 is powered by ±60V. AA-AB31394 is powered by ±92V and you can visit the link below: store3.sure-electronics.com/aa-ab31491 for more information. Thanks for your watching.

but as it says max 95v I wanted to know if it worked

It can work with 95V. Thanks for your watching.

what is the difference between 50A 100V 94000uF (Supports power converting for up to 1,500 watt devices) and 30A 100V 35000uF (For use with devices up to 2,000 watts) Fast Recovery Rectifier Capacitor Bank Board?? the 94,000uf should not support more power? thanks for the previous answers.

The 94000uf should support more power indeed. We will update our data. Thank you for your comments!

You might try a preamp?

You can use the RCA interface to connect our volume control board(store3.sure-electronics.com/aa-aa11117) to get the external volume control fuction.(Related videos：kzfaq.info/get/bejne/q8x5jbefqrnIcZc.html&pbjreload=10) Thanks for your watching.

Hi razva. This song is called Star Sky and was produced by the Two Steps From Hell. Have a nice day :)

The speaker is a toy, it is true, but this tiny is not a junk, it could output 2000Watt continuously, you can check another video when the amp is taking an air conditioner. 96% efficiency means it will deliver about 80Watt, only with a high speed fan, it could output RMS power continuously. Inductor only 95 celsius or so. I can not say this amp could work continuously cause it is not designed for long term running, but I will be glad to show you it could work at 2000Watts continuously for 5 minutes, and without any modification it could output 2000watts only with an additional fan. what about 200 bucks bet, the board value? So before you consider it as a toy, get things clear please.

bullshit a bullshit

Purifi

I have one stereo board from eBay cost me $130 USD(130x85 =11050taka) this single one would cost May be $75 USD. U wanna buy?
