This is a conceptual schematic of the signal path for the behringer U-PHORIA UMC404HD Audiophile 4x4, 24-Bit/192 kHz USB Audio/MIDI Interface with MIDAS Mic Preamplifers. A sweet, sweet piece of equipment.
Included is the diagram source in .dia format. Dia is a program for drawing structured diagrams (C) 1998-2009 The Free Software Foundation, part of the Gnome Project.
Also there is a rendered .pdf file of the schematic for your viewing pleasure if you don't have access to Dia.
The source and render are both placed in the Public Domain by me in the hopes that it will be illuminating to somebody.
If I've really gotten something wrong in this schematic, create an Issue or Pull Request and I'll update it.
I am available for all your corporate and personal diagramming needs. Located in Calgary, Canada (GMT-7) and world-wide on the internet. All jobs considered, reasonable rates.
After silence, music comes closest to expressing the inexpressible.
