I have a Steinberg UR-22 with two inputs, Input 1 and Input 2. There is a switch on the back panel that can turn on phantom power for both inputs. Unfortunately it’s not possible to turn on phantom power for just one input.
I connected an XLR cable to Input 2 and it gives phantom power between pins 1-3 and 1-2, and of course nothing between 2-3. There is another switch (button) on the front panel that can turn on high-impedance for Input 2. The phantom power stays on Input 2 if I turn on high-impedance. I don’t really understand why. Is there even any high-impedance input device that requires phantom power?
So I would like to record from the microphone while playing on the guitar. I would like to know is if I can plug in my unbalanced, high-impedance guitar and my condenser microphone together by turning on phantom power.
