Every installation technician has faced it or soon will; the dreaded hum bars on the screen, 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 micro-volts up to mili-volts or higher.

They 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. Ground Loop Isolation Transformers from Impact Acoustics 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. 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. At Impact Acoustics we recommend exercising patience while you work through test scenarios to eliminate your ground loops. While the problem is sometimes at the last component added or sometimes the furthest from the main system, these might only be symptoms of a harder to solve problem.

Features: Eliminate video noise caused by ground loops. Available for Composite, Component and S-video applications. Easy connection using standard video cables.
