  • Every installation technician has faced it or soon will - the dreaded humming from the speakers, a telltale sign of a ground loop
  • Ground loops are caused by voltage potential differences at the ground point on your equipment
  • Voltages in the range of microvolts up to millivolts or higher can cause ground loops
  • Ground loops occur when multiple audio/video components are powered from different outlets, most commonly, outlets that are tied to different circuitbreakers or even a different secondary from the power transformer
  • Ground loops manifest themselves in the form of speaker hum
  • Our isolation transformer easily connects into your audio/video system and breaks the ground path through cables between components
  • Start at the component last installed before the ground loop was discovered, and connect the isolation transformer at different ends of the audio/video cable until the ground loop is gone
  • Please Note: While this transformer is designed to eliminate ground loops, isolating the source of the ground loop can be very difficult even for professional technicians
  • Sometimes the problem can be at the last added component or at the furthest from the main system; however, these might only be symptoms of a harder-to-solve problem
  • Please exercise patience as you work through test scenarios to eliminate your ground loop issue
