A VU meter is an essential device that lets you monitor the audio levels in a circuit. This tells you if the volume of the audio is too loud for your equipment to handle, which would cause distortion, a usually undesirable effect caused by overly loud audio. Based on old analogue technology, the meter has a set of numbers written on it. In the negative range (say -48 to 0) the audio is at the appropriate level. Above 0, in the positive range, the signal is too loud and distortion, also known as clipping, will result. Warnings Writer Bio
