I was wondering if anybody had anything to say about this device. I am unable to find much info on the thing online.
I was also wondering if I understand this right. When wiring up the line in for the amp that then goes through a potentiometer (should I get 50kohm or 100kohm potentiometer?) that just attenuates the signal.
My concern is that if the amplifier is always at "full volume" any interference would then always be really amplified.
I may be forming my questions weirdly or even wrong and hoping you can help me.
oh and here is a link to the amplifier in question:
Yuan Jing Audio - TP2050 Class-D Power Amplifier Board [50W + 50W] - $24.50 - Class-D & T
Also if anybody can point out an off the shelf ac/dc converter to use with the project I have in mind. Preferably one that should be mounted inside the amplifier box.
Best regards,
Agustr.

I figured it's better to resurrect this thread than start a new one about the same amp.
What type of connector is used for the input on that board? I have the board, but I didn't notice when I ordered it that it didn't include one. Having the right one would simplify the box I'm making to hold it, but I don't know what to look for, having never purchased one of those separately (and I can't find ANY documentation on this board).
Thanks!

If someone, like me, wants to try a cheap TK2050 board with class T modulation: JINSHENGDA assemble TP2050 classe D AMP Kit 50 W + 50 W carte amplificateur numerique de puissance Audio-in Amplificateur from Electronique on Aliexpress.com | Alibaba Group
They state "TK2050" = TC2000/2001 and TP2050 but the TP2050 is often a STA508 which makes no real difference.
