Also take extreme care with EQ when mixing live shows, since minimum-phase equaluzers change the phase, so generally attempt to only apply EQ on the main bus but not to individual tracks. Definitely avoid minimum-phase HPF in this context. HPF changes the phase the most, and the steeper it is the more the impact. So for live shows, either use HPF on the main bus or use exactly the same parameters on individual tracks. You can use linear-phase, but it generally tends to make music sound like sh*t.
