Stereo Hi-Fi Balun (500028 & 500028-F)
Quick Installation Guide
Introduction
The Stereo Hi-Fi Balun (500028, 500028-F) 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. Used in pairs, the product is designed for high fidelity
applications where full audio bandwidth (20Hz to 20 KHz) is required. Used in pairs, the
Stereo Hi-Fi Balun eliminates costly and bulky audio cable, allowing audio equipment to
be connected or moved within a structured cabling environment. Applications include;
audio distribution, high-fidelity sound systems, custom residential audio systems.
Installation
To install the Stereo Hi-Fi Baluns, perform the following steps:
1. One pair of Stereo Hi-Fi Baluns is required for each stereo channel.
2. Identify the pin configuration of the baluns. Two (2) twisted pairs are required
as shown in the following diagram.
