Amplitube not capable of outputting 2 inputs at the same tim

[Vex785]

Im using a scarlett solo, XLR microphone plugged into channel 1, and my guitar plugged into channel 2 (1/4" jack) have headphones plugged into output 1 and 2, and no configuration within amplitube allows me to have it output both at the same time, not even in separate ears. Any solution or just not possible?
