So, I have this multi channel amp I assembled from hypex modules, and power supplies.
I have regulated the Vaux from the hypex smps to a 12VDC to feed the VU Meter board from aliexpress.
Ncore are balanced output, so I have used alligator clips on one of the XLR out (Hot and ground) to the Vu Meter board line in + and ground.
Consequently, VU Meter is showing only the bandpassed audio signal (I made the parallel connection on the mid amplifier, 300Hz-1800Hz)
And, it sort of works, since the needle goes to about half the meter with the preamp at -30dB (which is already a bit too loud for my taste) and the LED is bright enough for me with the 220 Ohms resistor I added on the 4 led input.
Questions:
Pictures of the setup which looks a bit ghetto at the moment...

Questions:
- is this setup somehow degrading the sound signal considering the parallel wiring & the board used? From what I read, it shouldn't.
- what should I do if I want to show the whole band on the VU? Connecting the three XLR hot and XLR gnd to the vu board in parallel? Is this advisable? is there another option?
