Description   Audio Authority 1184 Active Signal Hum Eliminator / DC Blocker The 1184 is designed to solve the rolling video hum bar issue typically caused by AC-line related noise from ground loops in coaxial cabling. Simply install at the input of any device, such as a television display, exhibiting signs of a ground loop. The 1184 also removes hum from low level stereo audio signals. Television displays and projectors often have a  connection between their audio and video inputs and chassis. A ground loop may develop across these inputs leading to 60Hz current from the AC power soruce flowing into the input cable, which causes hum bars. The  1184 uses active electronic circuitry to effectively isolate the input and output grounds. It also clamps the video signal to thoroughly eliminate artifacts caused by differences in AC voltage between the chassis equipment. Model 1184 also strips off sources of DC voltage on component or RGB video, and clamps the Y or RGB black level to 0 volts. Unlike passive devices, known as hum buckers or video transformers, the 1184's bandwidth is not limited by inductance.  Furthermore passive devices are inherently lossy–their gain is a little less than one–compared to the 1184, which has a gain of exactly one. Additional Applications Model 1184 can overcome hum bars on a Component or RGB display at the end of a long run of coaxial cable. In these cases, breaking the ground loop is best accomplished at the video input of an offending TV, projector, or video display. This situation may occur in a residence, but is more likely to manifest in larger venues, such as clubs and churches.   For example, if four displays are fed by a single component video distribution amplifier and ground current circulates between any of the displays and/or their source, hum bars will show on one or more of the displays. Installing  an 1184 at the input of the offending display to break the ground current path will eliminate the hum bars without sacrificing bandwidth or image quality.   Features * Eliminates video and/or audio hum caused by ground loops * Active circuitry prevents signal loss * Clamps video input to eliminate artifacts * Strips DC from source video output * Clamps black level to 0 volts * Input and output have 75 ohm termination * Can be used in either YPbPr or RGBHV mode * Wideband audio channels can be used for H and V in RGBHV mode
