Any ideas as to how these should be wired up based on current schematic?
Here's how I connected my VU Meters to the Amp. This is for the output. If you connect to the input that will show input level VU (Voltage) not the output VU (Voltage).
Hope that helps.
Stay Safe and well..
TY, saw that I will give it a try
I used these: https://www.amazon.com/gp/product/B07SFHV85Y/ref=ppx_yo_dt_b_asin_title_o00_s00
I used a board I bought off of Amazon. Then just feed the control board with the audio input to the amp.
