Mic USB Source Mapping
The mic signal, as can be seen in the previous Mic Signal Routing diagram, has two paths in which it can
travel up the USB port to the computer. Path E taps the mic signal off right at the mic input and sends
unprocessed signal up to the USB port. Path C taps the signal at the output of the RPx400 and can
include any effects processing that may be used. Below is a matrix to show where the signal is tapped
based on how the Mic, USB 1-2 Source, and USB 3-4 Source settings are configured.
