I want to use a single microphone throught my iRig Pro Duo to capture sound while filming with my iPhone XS (with the built in iOS camera app). However, I can't get it to record this as a mono signal, even though I switched off the "record in stereo"-option. Instead input 1 always get recorded solely in the left track, and input 2 in the right track. Is there any way to fix this (that doesn't include using a mixer or any physical adapter to send the signal to both inputs)?
