MuxLab IMU-500039-2PK - Composite Video and Hi-Fi Stereo Audio Extender Balun Kit (2 Pack)
The MuxLab 500039-2PK is the ultimate solution for audiovisual installations that require transmitting high-quality analog signals over extraordinary distances without loss of integrity. This kit of two passive baluns is specifically designed to extend composite video and Hi-Fi stereo audio signals using a single Cat5e or Cat6 network cable, replacing expensive and bulky coaxial cables with a much more efficient and economical structured cabling infrastructure.
Unlike conventional extenders that often sacrifice sound quality, this system stands out by offering a full audio bandwidth of 20 Hz to 20 kHz , guaranteeing crystal-clear sound fidelity across the entire hearing range. Its intelligent design allows for the simultaneous transmission of a video signal and two audio channels (stereo) over a single UTP cable, reaching distances of up to 670 meters for color video and audio, making it an indispensable tool for large venues and distributed systems.
Main features
-
Long-range transmission: Capable of sending composite video and audio signals up to 670 meters (2200 feet) using Cat5e/6 cable, far exceeding the limitations of standard RCA cabling.
-
High Fidelity Audio: Full bandwidth support (20 Hz - 20 kHz) for clear and faithful sound reproduction, ideal for music and multimedia applications.
-
Passive Design: It does not require external power supplies, which simplifies installation and frees up power outlets in the rack or behind the equipment.
-
Optimized connection: Uses standard network cables (UTP) that are more flexible, economical and easier to run through conduits than triple coaxial cables.
-
Color-coded cables: Integrated RCA patch cables facilitate a quick and error-free connection to source and destination equipment.
Product benefits
For systems integrators and audiovisual technicians, the MuxLab 500039-2PK represents a significant saving in time and materials. By eliminating the need for long runs of soldered coaxial cable, it drastically reduces installation costs. Furthermore, thanks to its efficient interference rejection, it ensures a clear image and hum-free audio, even in electrically noisy environments. Its compact form factor allows it to be easily concealed behind televisions, projectors, or inside junction boxes.
Use cases
-
Educational and corporate systems: Connecting DVD players, VCRs or document cameras to projectors and interactive whiteboards located at a great distance in auditoriums or lecture halls.
-
Digital Signage and Kiosks: Distribution of promotional content from a central server to remote screens in shopping centers or airports using composite video inputs.
-
Security and CCTV: Transmission of signals from analog CCTV cameras and microphones to security monitors or DVR recorders located in remote control rooms.
-
Distributed audio: Sending audio signals from a central source to remote amplifiers in background music or public address systems.
Frequently Asked Questions
-
Do I need to connect the baluns to the electrical current?
No, this model is completely passive and does not require an external power supply; it works using the signal from the video/audio device itself.
-
What type of cable should I use to achieve the maximum distance?
It is recommended to use solid copper Cat5e or Cat6 cable to ensure the maximum range of up to 670 meters without signal degradation.
-
Is it compatible with HDMI or digital signals?
No, this kit is designed exclusively for analog signals (RCA Composite Video and RCA Stereo Audio). It does not convert HDMI digital signals.
-
Does the kit include the transmitter and receiver?
Yes, the product is a pack of 2 identical reversible units; one works as a transmitter and the other as a receiver.
