CABLES TO GO COMPOSITE VIDEO ISOLATION TRANSFORMER
ELIMINATE AUDIO/VIDEO GROUND LOOPS
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 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 hum bars called herringbone (diagonal lines on the screen) and AC beat (a wide, barely visible bar that rolls from the bottom to the top of the screen). Often you can hear the ground loop as the noise on the video encroaches on the audio signal.
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.
Input: One RCA Female
Output: One RCA Female
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.
ISOLATION TRANSFORMERS
Video and Audio signals are delicate. Delicate signals are susceptible to distortion from ground loops. Ground loops are caused by voltage differences, which can range from a few millionths of a volt up to several tens of volts, between the ground point on your equipment and the grounding of your electrical service. If you have multiple A/V components powered from different outlets or even different circuit breakers then your system may not be operating at its maximum potential! Get isolated!
You can tell you have a grounding issue if your picture contains hum bars which form diagonal lines on the screen (called herringbone) or a wide, barely visible bar that rolls from the bottom to top of the screen (called AC beat). Often you can even hear a faint hum caused by the ground loop as the noise on the video encroaches on the audio signal.
Ground Loop Isolation Transformers from Impact Acoustics break the ground path between components, eliminating performance robbing ground loop interference. Isolation transformers are offered for component HDTV video, S-Video, composite video and audio applications.
