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.
Ground Loop Isolation Transformers from Impact Acoustics™ connect easily into your A/V system and break 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 A/V cable until the ground loop is gone. We offer ground loop isolation transformers for composite video, S-video and component video applications.
Please note: While these transformers are designed to eliminate ground loops, isolating the source of the ground loop can be very difficult even for professional technicians. Now we recommend exercising patience while you work through test scenarios to eliminate your ground loop. While sometimes the problem is at the last component added or the furthest from the main system, these might only be symptoms of a harder-to-solve problem.
