Hello Wondom Team I have 2 of AA-AB31382 boards, each connected to 2 subwoofers in parallel which ends in 1,8ohm load per board. To get out 2kw of clean audio signal to the 1,8ohm subwoofer load, which voltage of line in signal is needed? You set the signal to 1.32vrms right? Can i get 2kw with 0,9vrms input signal? -> out of an adau1701 DSP board?
Hello, with 0.9Vrms input signal voltage and 33dB gain, the output power will be less than 900W into a 1.8Ohm load. If you want 2kW output power, 1.35Vrms input signal voltage would be required. Wish this could help you. Have a fantastic day~
What ist the max output in Volt RMS of the Control Board - PGA2311? The amplifier needs 1.35 Volt for the max. Output, can the Control Board - PGA2311 deliver this voltage? And is it possibe to set an fixed volume to the Control Board - PGA2311 even when its powered down? So it starts ever with the same volume? If the volume is set, can the rotary encoder be disconected, so no one manipulates the volume? Or is this not possible?
Hello. The control range of the PGA2311 volume control board is -95.5dB to 10dB. 10dB equals to 3x magnification. The supported maximum input voltage without clipping is 2.5Vrms. Due to the power supply limitation, the maximum output voltage is 3.5Vrms. Given the input voltage is 1Vrms, you can expect a maximum output voltage of 3Vrms. Please note that the parameters are saved in the rotary knob, therefore, the rotary knob cannot be removed. The PGA2311 volume control features power-off memory function, so it can remain the last configured parameters even if it's powered off. Wish this could help you. Have a fantastic day~
Hello, the fan is temperature-controlled and will be activate when the temperature reaches 50℃. We can see that the fan turns on at 3:17 of the video when it's tested for about 1min50s.
Hello, you can place order in our online shop: store.sure-electronics.com/home. You can check the price and freight when placing orders. Have a fantastic day~
Hello. We are delighted to inform you that we offer shipping services to Colombia. To proceed with your order, we kindly request you to visit our AliExpress shop using the link provided below. It will serve as a handy reference for you. Thank you for considering our products! Have a great day~ www.aliexpress.com/store/1101856091?spm=a2g0o.productlist.main.2.402b243c5dbGgl
This amp is majorly designed for industrial applications, for example, vibration test machines, they need very high power at 50-500Hz, so they need tough design. We don't use RMAA, we can provide AP and Rohde Schwarz Audio Analyzer test report if you want, we will provide in different videos.
@@WONDOMAudio Thank you for your reply. Would be a good idea for an audio amplifier use sinus signal until it clips under giving load (4 or 8Ohm) and TRUSTY rmaa test. Lots of DIYers will be after your product. At this moment we only see some strange pointless videos. I'm writing this post just for myself 🤔😂 to understand point to have abilities create good product and then make a mess with presentation and specifications (memes about chinise Watts) Hope to see some more your good products in the future👍
Hi Sergey, Really appreciate your feedback. We are also wondering what kind of topics will really help our customers, could you please let us know a few of your opinions? For example, which topic you would like?
@@WONDOMAudio If you want improve something try be honest with your customer.If board has a little buzz in speaker say about it 🙃. Would be great to see the technical way presentation (see my suggestions in previous post) and then real life speed assembly with only necessary speed up moments. Sometimes userfull sketch of your connections. P. S. If you have access to developing this products please, pleeese... please never put voices during connection to Bluetooth/WiFi etc. 🙏
What is the input? Why you not present the output wave?
you can see the input from the wave generator, output wave was shown in previous videos, in this video we are demonstrating output power only.

Great Product.
Thank you. Have a fantastic day~
Well, it's a bit strange that with such power the fan didn't turn on.
Hello, the fan is temperature-controlled and will be activate when the temperature reaches 50℃. We can see that the fan turns on at 3:17 of the video when it's tested for about 1min50s.
How to purchase in india and price
Hello, you can place order in our online shop: store.sure-electronics.com/home. You can check the price and freight when placing orders. Have a fantastic day~
🤔 so... you need a 3KWatt PS to power a 2KW audio amp.🤷♂️

How much power supply?
This amplifier has multiple versions, in this video, we are using a 3000W 120V power supply unit.
Это видео из тиктока?! На кого оно рассчитано? Что мешает сделать замер чистого синус сигнала?🤔 Где замер в программе RMAA?😭 И всё!

What a joke bro amplifier board off but song play
