Researching a diy volume control for Mosconi 6to8v8. The processor has a controller jack which looks to accept a rj12 connector. The pin out diagram is no where to be found. I found a few pics of the board online but cant read it. Does anyone know the pun out config or have decent pic of the board to possibly see the config?
I would also like to confirm that the default for the dial on the controller is for volume control? The manual shows to click the dial to scroll through the other functions, fader, balance, presets.
Since the rj12 has 6 contacts I believe on would be positive and one ground. The remaining four would be for control. Determining which pin is ground has me stumped without taking out my dsp and opening it up.
The only function I am interested in is volume control. Have no need for balance, fader, presets. Thinking a potentiometer would work, or possibly tying into the steering wheel controls if possible.
Reaching out for some help guidance? Is this doable?
