Allen Avionics has developed a family of wide bandwidth ground loop hum eliminators. These products will satisfy the broadcast industry's need for wide bandwidth components for use in high definition video applications, high speed video switching systems, high resolution or high definition video display and projection systems and for all wide bandwidth analog and digital transmission applications.

Differences in ground potentials, unbalanced power loads and large multi-wire and multi-cable video or serial data distribution systems using coaxial cable can form ground loops and become a receptor for unwanted energy. This unwanted energy results in common mode currents flowing in ground loops.
