Stereo PC-Audio Balun (500030)

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.


Installation


To install the Stereo PC-Audio Baluns, perform the following steps:

1.

One Stereo PC-Audio Balun is required for the PC stereo output.

2.
