Line Check: Action (verb).  “Line check” is the act of testing and confirming audio input lines between soundboards and sound sources both on and off the stage.

Often includes trouble-shooting when things go wrong or simply don’t work correctly.  Example:  “There’s a buzz on the guitar line” (no kidding) says the FOH “sound man”.  “It’s clean for me” says the monitor “sound man.” 

This scenario might result in the renowned sound-man/technician test-tool showdown. “Hey, let me get out my whiz-bang-gizmo and I’ll tell you what’s wrong”.  Problem solved. 

The idea of “Line Check” is to check the lines before the artist shows up onstage.  NEVER to be confused with “Sound Check”, which is strictly for checking the sound.

Q:  What’s the difference between a hum and a buzz?

A:  A hum could be a quiet way to sing without being too publicly obtrusive and a buzz could be a nice way to spend an evening with your significant other.  Hmmmm.  Zzzzzzz.  Both are a “down to earth” way to relax, in a manner of speaking.
