MuxLab IMU-500049 - Stereo Audio and Composite Video Balun with IR Return (Female)
The MuxLab IMU-500049 is a comprehensive connectivity solution designed to simplify and extend professional and home audiovisual installations. This device, known as a Stereo AV/IR Pass-Thru Balun , enables the simultaneous transmission of a composite video signal, analog stereo audio , and an infrared (IR) control signal over a single Cat 5e or Cat 6 network cable. Its passive and robust design makes it the perfect tool for integrators looking to eliminate the clutter of multiple cables without sacrificing signal quality over long distances.
Unlike traditional coaxial cables, which can be bulky and prone to interference over long runs, this balun leverages existing structured cabling infrastructure. Equipped with gold-plated female RCA connectors to ensure optimal conductivity, the MuxLab 500049 offers exceptional reliability. Its ability to manage IR return is a standout feature, allowing users to control source equipment (such as DVD players, set-top boxes, or media systems) remotely from the display or projector location, adding an essential layer of functionality for control and entertainment rooms.
Main features
-
"All-in-One" Transmission: Sends composite video (yellow RCA), stereo audio (red/white RCA) and IR control signals over a single UTP cable.
-
Extended Range: Capable of transmitting color composite video up to 670 meters and audio signals up to 990 meters , far exceeding the limitations of standard cabling.
-
IR Return Channel: Uses the fourth twisted pair of the network cable to pass the signal from IR emitters, facilitating remote control of hidden or distant devices.
-
Passive Design: It does not require external power supplies, simplifying installation in tight spaces or behind televisions where sockets are scarce.
-
Universal Compatibility: Works with NTSC, PAL, and SECAM video formats, and offers a full audio bandwidth of 20 Hz to 20 kHz for high-fidelity applications.
Benefits for the user
Using the MuxLab 500049 transforms how AV signals are managed. For installers, the main benefit is reduced labor costs and time , since running a single Cat 5e/6 cable is faster and cheaper than installing three separate coaxial cables plus a control cable. For end users, the benefit lies in aesthetics and control ; it allows for centralizing equipment in a ventilated and secure technical cabinet, keeping only the screen and IR receiver in the viewing room, resulting in a clean environment free of visible electronics.
Use cases
-
Classrooms and Training: Connecting a computer or multimedia player on the teacher's desk to a ceiling projector or distant monitor.
-
Digital Signage: Distribution of promotional content in shops or hotel lobbies where the video source is in a back office.
-
Home Theater Systems: Extension of signals from a centralized media rack to televisions located in other rooms or outdoor entertainment areas.
-
Conference Rooms: Integration of videoconferencing and presentation equipment with full remote control from the meeting table.
Frequently Asked Questions
-
Do I need a power supply for this balun?
No, the MuxLab 500049 is a passive device and does not require any external power supply.
-
Does this balun work on its own or do I need another one?
The baluns operate in pairs (one at the transmitter and one at the receiver). You can use two 500049 (Female) units connected to your devices with short RCA cables, or combine them with the 500048 (Male) model for a direct connection, depending on your needs.
-
How do I connect the IR?
The device has a terminal block or access to the fourth twisted pair of the Cat5e/6 cable, allowing the connection of compatible third-party IR transmitters or receivers.
-
Does it support high-definition video (HDMI)?
No, this model is specifically designed for analog composite video (yellow connector) and stereo audio. It does not transmit HDMI or digital signals.
