Show me assigned! Although ‘routing and grouping’ sounds like something from a Fifties song (“C’mon everybody, we’re a-routing and a-grouping…”), it’s an important area if you are going to get a handle on how signals are moved and managed on a mixing console. With that aim, we’re going to use Diagram N as our reference. It shows the mic/line input (1), subgroup, or group (2) and main mix output (3) strips from a Soundcraft GB2 console. Other mixing systems may not be identical, but the fundamental ideas can be transferred to almost any desk. It’s the areas marked in black we’re concerned with today.
