Introduction
The Dual Stereo Hi-Fi Audio Balun(M-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 ormoved within a structured
cabling environment.
Features
20 Hz to 20 KHz bandwidth
Cost-efficient cabling
Up to 3025ft (1,000m) via Cat5e/6 UTP
Quicker moves, adds and changes
