XLR input and output “HUM KILLER” Audio Isolation Transformer
Galvanic isolation between the input and output is provided by a studio quality audio transformer. The AV-HK1X breaks the "ground loop" connection that can produce hum in a sound system. The input connector shield does provide a radio frequency ground return, thereby preserving system immunity to radio interference.
