Amplifier Aiyima TPA3116 2.1 case
Description
This is a case for a Amplifier Aiyima TPA3116 2.1. It is a digital amplifier class D2, with 3 outputs, 2 for left and right channel and one for a subwoofer. I measured some power supplies. And input voltage is from 6V / 9A to 24V / 2.5A. But best and safety power supply is a laptop 19V / 4A or 5 Amps. Connector if does not fit, you can it cut and make some direct connection to the PCB. Output is stereo 2x 50 Watt + subwoofer 1x 100 Watt. Recommended speakers are 2x 4 ohm / 50 Watt for Left / Right channel. For a subwoofer is recommended a speaker with 2 ohm / 100 Watt. PCB board I bought from this link: https://www.aliexpress.com/item/DC12V-24V-2-50W-100W-XH-M139-2-1-Channel-digital-Subwoofer-Amplifier-Board-Chip-TPA3116D2/32574627375.html?spm=2114.search0104.3.6.5cd17d8d49Ra9v&ws_ab_test=searchweb0_0,searchweb201602_5_10065_10068_5731315_318_10890_5730315_319_10546_10548_317_5728815_10696_10084_10083_10618_452_5729215_10307_10820_532_5731115_10303_5731415_5731215_5731615_204_5732015_328_10059_10884_5731515_323_325_10887_100031_320_321_322_5732515_10103_5731715-10890_5731415_5731215_5731315_5731115,searchweb201603_55,ppcSwitch_0&algo_expid=63846a05-18ea-4945-a749-d46dc52f3bd4-0&algo_pvid=63846a05-18ea-4945-a749-d46dc52f3bd4 On a front panel you can see on left side a small hole. Its for a LED diode from board. If you want to change it to panel view.
