Mamocel,
what happened to your VU-Meter case project?
Or are you waiting for Vitaly amplifiers ...
Interesting whether the VU meters cause any interference on the amplifier ...
What do you think?

it's in my garage ...
I can turn the knobs ... No sound comes out ... :D:D:D
The seller from the land of the rising sun answered my questions anyway!

You can connect the view meters either as an amplifier input or output.
I will choose the amp output, to avoid distorting the input signal ...
My Vitaly amp is on the road, the tracking statue has not changed for the moment ...

I think I know ....
The inputs of the card have a common ground ...
Therefore, not compatible with class D amps.
This will be by deduction connected to the signal input.:violin:

As long as Vitaly amplifier is not there, I am busy with my 3d printer ...
Right now he's printing a Cable_holder_for_soldering ....:):)
