The 3116 shutdown current is supposed to be 50µA... Operating quiescent current is usually 20-50mA (with connected load) so it does seem like that switch might be the mute mode. Or maybe even one of those fake input caps is bad... You can check if the switch mutes/shutdown the chip because removing the power otherwise causes a small pop on the output (the datasheet tells you to put it into shutdown before disconnecting power to minimise the pop). By the way, the normal power-on time is 10ms, 3fast5me.
Hi there. Thanks for great videos. I have the same amp you show to us, that is packed, for 2.1 with caps on the other side. There is 2 TPA3116, one for sub and one for right and left. Can you please make a video about that amp?
Hey ya what 3CH with bluetooth would you recommend? I bought and audio amp with a sub and two satellite speakers. cabling and i forget what else. i would like to set it up with bluetooth.
FreshLemunz That Linep thing looks silly expensive for what it is. The Sure Electronics ones, though - they do look interesting. Sure tend to put some effort into the stuff they put their brand upon. Thanks for the links, I might look into them.
I have the nobsound dual tpa3116, the gain is too high, ive seen you do the modification on a breeze audio single tpa3116, is it possible to guide me do it on my amp? i know how to solder and desolder, i just dont know what to replace.
Awesome work !

I changed the caps to Bipolar Nichicon Muse Audio, now the sound is great, but i cant close the case 😜
You could fit a couple of really small fans to the heat sink and it may be ok.
Awesome. Any audio quality difference with 12v vs 24v adaptor ?
No, it just goes louder.
Clever chap

Hi. I have the same... Can you advise on bass improvement??
What is this language? I didn't understand 90% of video. English is not mine mother language but I understand it.
+ksrele What is this English you speak about? I only speak Nerd.
have you seen the sure amplifiers or the new linep amps? I am really interested in these. Not sure if I should take the chance on one of these
+FreshLemunz I'm not sure what you're referring to, link me and I might check them out.
+FFcossag Sorry about that. I will.

I've heard decent things about sure.

Make a review if you do!
Product link provided please
Thumbs up :)

which is the difference from the two boards that you bought on aliexpress ? what is the best?
I found this on ebay , it is the same ? www.ebay.it/itm/311616288645?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
The black board is better. I know nothing about that amplifier you linked.

Very much possible, look at the data sheet and replace the resistors that control the gain
what is the temperature with a 12v power supply?
Temperature basically scales linearliy with output power, so it's going to be considerably lower since you'll just get about 5 W out of it.
20.48 watts at 8 ohms, not to bad. But still these little amps are a bit disappointing.
Order the real chip and replace it to see what happens.

interesting. I really don't care for these Chinese integrated amps.
