Quick Installation Guide
Introduction
 
The VideoEase Stereo PC-Audio Balun (500030) allows unbalanced line level stereo 
audio to be transmitted up to 5,000 ft (1.5km) via unshielded copper twisted pair (UTP) 
in a point-to-point connection. The product is designed for mid-range audio applications. 
Used in pairs, the Stereo PC-Audio Balun eliminates costly and bulky audio cable, 
allowing audio equipment to be connected or moved within a structured cabling 
environment. The 500030 also works in conjunction with other MuxLab audio-video 
products including the 500001, 500012, 500019, 500027 and 500200 for a more 
complete cabling solution. Applications include; audio distribution, custom residential 
systems and intercom systems.
