I have an LED VU meter circuit on the output of my LA2A, and a separate LED VU meter circuit on the Peak reduction.
When they have their own battery power supplies, I can calibrate both meters to give a satisfactory visual.
However, when i power both circuits with the same battery supply, the Output level indication bleeds through and dominates the Peak reduction circuit.
How can I isolate these circuits to use a single power supply?
I plan to use a 12-0-12 PT with a fullwave rectifier. I haven't had a chance to hook that up yet, if I separate the two power nodes with a resistor and their own Elytic, will it help my problem? Or will sharing the negative cause this issue to persist?
I'm really close to adding LED VU visuals for an LA2A and this is my last hurdle before I share it all in my thread.
Thank you!
