A short video showing how to set the channel gain control using the Pre-Fade Listen button in conjunction with the meters. Mixer shown is a Soundcraft Spirit Live 4/2 but the general principle can be applied to any mixing console.
A couple of questions that come up quite a lot in the comments:
Q: Where should the channel fader be during this process?
A: I recommend keeping the channel fader all the way down whilst setting gain just in case the input level is higher than expected.
Q: Where should the master fader be during this process?
A: I recommend keeping the master fader at 0dB/unity.
