What is a 'Line Check'?

A line check is a crucial part of live event production, especially in the music industry. It is a process where the audio engineer checks each channel of the sound system to ensure that all the equipment is functioning properly and that the sound levels are balanced.

How It Works

During a line check, the audio engineer will go through each channel on the soundboard and test the signal flow from the stage to the speakers. This involves checking microphones, instruments, and any other audio sources to make sure they are all connected and producing sound. The engineer will also adjust the levels and equalization as needed to ensure a clear and balanced sound.

Importance

A line check is essential for preventing technical issues during a live performance. By thoroughly testing each channel beforehand, the audio engineer can identify and address any potential problems before the show begins. This helps to ensure a smooth and professional sound experience for both the performers and the audience.

A line check is also done in addition to or instead of a more comprehensive sound check.
