Hi buddy, I bought a Douk Audio, TPA3116 Nobsound Bluetooth 2.1 Channel Amplifier Board, it worked ok for about 6 months but the Bluetooth stopped connecting regularly, like it's random. I was wondering is there a way I can bypass or replace the onboard bluetooth? I have built a boombox and I don't want to have to put a different style amplifier in it as the knobs are in different places if you see what I mean? It's a shame these things are so unreliable and they are not inexpensive either like the normal cheap ones, I expected a bit better quality, any advice would be gratefully received. Next time I'll just buy the amp and bluetooth separate. Just to say this amp has not AUX input, it has the socket but apparently it does not function so I can't use a USB bluetooth via a 3.5mm input, which I didn't know and they said it worked so eh, go figure. Thanks for any help you can give me or even if you know of a video that might help, I'll be using you channel to help choose my next amps et al, subbed! ;D
Hello, I'm sorry you encountered a problem. It's recommended to set up the 3.5 mm jack (pins) and use a separate Bluetooth audio receiver module. If this does not work, you can search for the IC datasheet online. Locate the audio input pins and very carefully solder the stereo output to the IC audio input pins. Please note that this task is quite challenging and requires a high level of skill.
thank you. The ZK-MT21 model is almost identical to the model 2 introduced in this video. with the difference that it has more possibilities. In the future, we will post an introduction and review video about ZK-MT21 on the NEWTECPRO channel.
First amplifier name please

what about the wuzhi audio ZK-MT21

Arylic 2.1 board smashes all of these shitty boards
Thanks for your comment. Have you used these amplifier modules? What do you think is their main problem?
