How to use THX Competitive Mode in CS:GO?

Hi there,

I don't understand what in-game audio settings I must have in order to properly use the THX Competitive Mode in CS:GO. I have the Blackshark V2 headset.

These are the audio in-game options:
- Audio Output Configuration: stereo, quad, or 5.1 ?
- Advanced 3D Audio Processing: On or Off ?
- Audio Device: I guess it's THX Spacial Audio

Should I use any Enhancements?

Thank you very much
