Product Information：

Overview

The Dual Stereo Hi-Fi Audio Balun(MB-DSHFB) allows unbalanced line level stereo analogue audio to be transmitted via Category 5/5e/6 unshielded copper twisted pair (UTP) in a point-to-point connection. The product is designed for audio applications where full-range, hi-fidelity audio frequency response is required.

Used in pairs, the Stereo Hi-Fi Balun allows audio equipment to be connected or moved within a structured cabling environment.

Applications

Boardroom systems, classroom training,

auditoriums, custom home installations and

intercom systems.

Features & Benefits

20 Hz to 20 KHz bandwidth

Cost-efficient cabling

Up to 3025ft (1,000m) via Cat5e/6 UTP

Quicker moves, adds and changes

Quick Setup Guide:

Plug the left and right RCA connectors of the transmit Balun into the audio output of the source component, plug the left and right RCA connectors from the receive Balun into your desired input component. Insert the CAT5 cable into both ends of the Baluns. You may use standard EIA 568A/B Termination.
