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.
