Definition: A ground loop is commonly found in studio or live sound situations as the cause of unwanted hum within a system.
A ground loop happens when unbalanced connectors are connected together through two separate grounding paths. This creates an unwanted hum as the power grounding is sent back through the unbalanced connectors.
Many mixers and DI boxes have a "ground lift" switch, which helps eliminate ground loop noise.
