The I•ONIX U42S unit gives you the ability to hear your analog input sig-
nals directly and immediately while recording without having to adjust levels
in software and before the delay caused by digital converters and computer
recording latency. This zero-latency analog monitoring is controlled by the
Monitor Mix knob, which you can use to adjust the blend between the
live analog inputs (called "Direct") and any sounds coming back from the
computer via USB ("Playback"). To hear only the live source input signals
plugged into the U42S, turn the Mix knob fully left to Direct. To hear only
the mix from the computer, turn the Mix knob fully right to Playback. The
output from the Monitor Mix control is routed to the Main outputs and
Headphone outputs.
