What a worship tech should NOT do is tweak the EQ settings throughout the service. A good rule of thumb is to only make changes the congregation would notice. For example, don’t make a 2dB boost in the acoustic guitar at the 500 Hz range because you think it needs it. The congregation won’t notice. Same with minor volume changes. Don’t mix like you’re mixing in a studio.

The Take Away
The biggest fear each new worship tech encounters is the fear of failure. The result is the hesitancy to change an EQ setting or an effects setting. They’d rather keep the mix as is instead of improving it because the moment they touch the console, they believe they could make it worse. That, my friend, is just part of the job.
In the fictional book You Can’t Go Home Again by Thomas Wolfe, there’s a wonderful line that applies perfectly to live audio production; “Make your mistakes, take your chances, look silly, but keep on going. Don’t freeze up.”
