Jon shares some great advice about keeping your faders at zero when mixing live. Around the zero mark is the area where you have most control on the fader, and keeping them all at the same level (adjusting the gain to be able to do this) also means you know where the faders ought to be in the event of something being knocked accidentally. He also describes micing on VCAs and subgroups.
