I need to implement a quick volume control solution for a testing setup. Something like a resistor across interconnects. What is the correct way of doing this? Resistor in series to interconnect, parallel, or to some other ground, and if so, which? Thank you!
Thank you that helps!
So if i understand things correctly, the easiest way to lower the "volume" is to add a resistor between the + and the - leads of an (single ended) interconnect, and do the same thing for the other channel?

Not exactly... your using the word resistor, so you need two resistors in series across each interconnect with the output taken from the junction of the two and "ground" or - as you called it. Aim for around 10 to 20 k total resistance.
Or a pot wired with the two end tags across + and - and the output from the middle and -
Do you see 🙂

A good primer. Too bad they did not mention loudness corection, L-pads and T-pads. Just messing with JL888's head. E

... and then, if you want to make it a little less quick and dirty, you could put an opamp buffer on... both sides? Just one side? If you want just a bit of gain, it would be best to dial that up after the pot?
