Ground loops occur when multiple A/V components are powered from different outlets, most commonly outlets that are tied to different circuit breakers or even a different secondary from the power transformer. Ground loops manifest themselves in the form of hum bars called herringbone (diagonal lines on the screen) and AC beat (a wide, barely visible bar that rolls from the bottom to top of the screen). Often you can hear the ground loop as the noise on the video encroaches on the audio signal.

Composite Hum Eliminator Features:

Eliminate video noise caused by ground loops
Also available for component video applications
Easy connection using standard video cables

Ground Loop Isolation Transformers connect easily into you re 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 that while these transformers are designed to eliminate ground loops, isolating the source of the ground loop can be very difficult even for professional technicians. 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.
