Quick Installation Guide
Overview
The Stereo Hi-Fi/Video Balun (500039-GLI) allows a single composite video signal to be
transmitted via an unshielded twisted pair (UTP) cable up to 2,200 ft (670m) in a point-to-point
connection. The Stereo Hi-Fi/Video GLI Balun features full audio bandwidth response for high
fidelity applications and features built-in color-coded cable leads for ease of installation. The
product is designed for installations that require ground loop isolation (GLI) and may be installed
either at the camera or DVR side. The product may be mixed and matched with other passive
MuxLab CCTV baluns including the 500039 Balun and Audio-Video Distribution Hub (500200) to
allow composite video programming to be distributed via UTP. Applications include: Classroom
video distribution, commercial and home audio/video systems, hospital video training, video
conferencing, and video kiosks.
NOTE: one GLI type balun in pair of baluns is sufficient to provide distortion free performance.
