Notepad 12fx USB return to headphones
I just bought a Soundcraft Notepad12fx to use in a small home studio. I am trying to playback recorded tracks and want to hear the USB return channels in my headphones. I have pressed on the MASTER/USB RTN 3-4 button but no sound is coming through my headphones. The levels on channels 9 and 10 which is where the return is supposed to come in are up. The return is reaching the mixer because the the led signal lights are moving I just can't monitor through the headphones . If I leave the button on MASTER, the sound is monitored in my headphones. I have not received my speakers yet but I am pretty sure that the return will go through the speakers (which I don't want). How do I monitor the USB return through my headphones? I am using a Mac with Sierra 10.12.1 and have tried with both Audacity and Garage Band with no success.
