DIGITAL MIXING CONSOLES
Besides a high CBL factor (colored blinking lights – an industry standard measurement) digital mixing consoles offer some very useful benefits:
Remapping the control surfaces for different events or operators is a breeze. For example, an experienced engineer mixing for a large band with backup singers has a different set of needs from an apprentice operator mixing for a small wedding.
Multiple control locations allow a front-of-house engineer to mix from a prime listening point, while a recording engineer can mix the same event from an isolated booth. With digital consoles, this becomes far more cost effective and simplifies the design requirements.
Automation is possible when using control systems. In the analog world this would have likely required split audio paths.
When integrated into a purely digital cabling infrastructure using digital stage boxes, snakes and I/O panels, cabling requirements are reduced, grounding issues essentially disappear and future scalability dramatically increases.
While not unique to digital boards, it is worth pointing out: flying faders make you look awesome.
