BIAS Mini's FX Loop volume knob and unit gain

[mcamelo]

In the BIAS Mini, what position of the FX Loop volume knob represent's unit gain? In other words, assuming that I can both amplify and attenuate the FX Loop's signal level using the volume knob, at what position am I not doing either?

@mcamelo The FX Loop on BIAS MINI is in between Power Amp and Cab section.
