  • umc-404hd-signal-path

    Signal path diagram for the Behringer UMC-404HD audio interface in .dia and .pdf format.

  • With respect to direct monitoring, you may find this signal path diagram helpful: https://github.com/mcnster/umc-404hd-signal-path/raw/master/umc404hd.pdf . In particular it shows that with the MIX knob turned counterclockwise to the IN position, the inputs are routed to the main output and also, if the a/b monitor switch is elevated, to the headphones, but not to the other outputs.
