Guitar and Vocals live through POD HD500x in POD HD Posted August 28, 2014 So just plugging a jack to nowhere will keep the summing from happening, but still allow me to take a right signal (lets say) from the unbalanced ts out and a left signal from the balanced xlr out? That would be ideal, since I wont have to worry about high/low impedance issues.Plugging a jack with no connection on the other side still leaves the circuit open though. Would I need to plug in a jack that shorts the live signal to ground? (connect the tip to the sleeve connections on the inside of the jack with a copper wire jumper)I guess I'll just try plugging a cable in and see what happens, I don't want to short the audio signal to ground if I don't have to. Plus, I know doing that wouldn't harm an analog circuit, but I know squat about digital and like I said I'd hate to fry something!
