It’s almost here! The next couple weekends will be full of Christmas plays, concerts, and cantatas. We volunteers are in the midst of the chaos right now, and we had better be ready for some troubleshooting.
Among the many problems we may encounter during rehearsals, non seems so annoying as that dreadful buzz coming from the speakers. In order to shoot-the-trouble, it’s important to know what causes the buzz and how to fix the problem.
It could be as simple as a power cord running parallel to an audio cable, or as huge as a bad channel on the mixer. I find it helpful to have a list of possible problems and a logical way to work through solving the issue.
We had an issue with the foyer speakers a few months ago. We spent weeks listening to the problem, checking connections, fiddling with settings. Finally, we traced it all the way back to the mixer board. What we thought was a cable or hardware problem, turned out to be a bad auxiliary.
Hope you figure out that buzz quicker than we did. Good luck with your productions!
