StudioLive-16.0.2-USB w/ PC Coectivity for Winamp, Discord, Other Desktop Audio

Can an Audio Device, such as OBS(open broadcaster software), WinAmp, Discord, or any other PC App w/ audio be coected to a specific chael on this board, and levels adjusted via sliders. Does each chael have a separate Input/Outputs that show up in the Playback & Recording Device Tab?

I have several audio tracks via PC(music, game sounds, Discord voice chat) that i wish to mix via the Mixer, then output back to OBS for broadcasting live to Twitch.
