Allow routing USB in audio back to USB

I use QC to stream my guitar playing with OBS. I send computer audio to QC via the USB cable but currently now I have to use an external mixer to route audio form 1/2 (XLRs) to get the audio back to computer mixed with the backing track and I don’t get why that’s the only option.

Is there something physically in the device preventing us from deciding where we want to route the audio in to? I understand that people doing recording don’t want that to happen, but why not let us control it ourselves?

My setup would be a hell of a lot simpler without having to do an unnecessary digital → analog → digital conversion to degrade audio quality just to get the synced audio back to my computer.

Hi, the QC is designed to work with several USB channels, reserving USB Output 1 & 2 as the “main” output to send to monitors.

If you’re working in a DAW, you can route USB outputs and inputs between your computer and QC (including the grid) for this kind of playback scenario.

I’m not familiar with OBS and therefore don’t know if it allows flexible USB routing.

You can do exactly what you are suggesting. Here is a video that explains how to mix multiple inputs to the same output. In your case you would be sending everything to the same USB outputs.
