How does a sound-check happen? In EDC’s blog we chat about what factors go into a live show, and explain the process. Before the Soundcheck You don’t want to wait until the band starts singing to find out you have a bad cable. The soundcheck begins before a band ever arrives. The sound designer and engineer begin by setting the input levels or gain structure; usually, there’s a check done on this every week. You can’t just set your inputs or gains and leave them be, they have to be adjusted to each band. Then the crew moves on to.
