Mixer Config Stereo FX

I see in the mixer config screen that you can assign stereo fx sends.

It was my understanding that the fx are stereo even if you use a mono fx send.

What (if any) benefit is there to setting up stereo fx sends?

Differences are :

  • mono send : all your sources are summed to feed the Fx processor and stereo is created by the Fx proc but without pan.
  • stereo send : offer the possibility to pan your sources before to feed the Fx processor.
    In this case, for example if you have 2 guitars who are panned left/right in your main mix you can also pan in the Fx.
    Gtr 1 feeds Fx L input channel and Gtr 2 feeds Fx R input channel.
    Panning will be respected in the Fx return.
