Excellent demo

[@Jon-Sen]

I have similar amplifier same size but using tpa3116. This amplifier benefits more on 24v, this board doesn't suck much power on 12 to 19v that's why it distort.

Hi, I'm building the same speaker.
I want to power it with a battery. So I need help to determine the final power consumption and battery size. 2 speakers, 10w each. with the same digital bluetooth amp.
Thanks

That's Chinese watts. 50watts @100% THD. But overall not a bad board if ran at low power to keep distortion down.

Agreed, it uses some no name chip that I don't trust very much for hifi performance

[@peterfhere9461]

If the epakers are connected when the amp is turned on you'll get an announcement through the speakers.....

No, it's stereo. You can connect two.
