Overview
The Stereo Hi-Fi audio balun (MB-SHFB)
allows unbalanced line level stereo analogue
audio to be transmitted via Category 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
eliminates costly and bulky coaxial cable,
allowing 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.
