MuxLab 500027 - Stereo Audio Balun Extender (RCA to RJ45)
The MuxLab 500027 is a high-performance stereo audio balun designed to extend line-level analog audio signals over extreme distances using standard structured cabling. This passive solution allows you to replace expensive and bulky coaxial cables with a single Cat5e or Cat6 UTP network cable, greatly simplifying installations in commercial, educational, and residential environments.
This device is ideal for applications requiring reliable and cost-effective point-to-point audio transmission. Its compact design with integrated patch cables allows it to connect directly to audio sources or receivers (such as DVD players, computers, amplifiers, or mixers) without the need for additional adapters. Operating passively, it requires no external power supply, simplifying cable management in racks or behind equipment.
Its internal engineering guarantees clean transmission, maintaining signal integrity even at distances of up to 1.5 kilometers . Furthermore, its common-mode rejection capability helps eliminate noise and hum typical of ground loops, ensuring clear audio in environments with potential electrical interference.
Main features
-
Extended range: Allows you to transmit stereo audio up to 1.5 km (5,000 feet) using inexpensive UTP cable.
-
Passive design: It does not need electrical power; it works simply by connecting the wiring.
-
Direct connection: Equipped with male RCA connectors on color-coded (Red/White) pigtails for quick channel identification.
-
Cabling compatibility: Optimized for Cat5e and Cat6 cables, leveraging existing network infrastructure in buildings.
-
Durable casing: Made of high-durability, flame-retardant ABS plastic.
Benefits of the system
Using the MuxLab 500027 transforms the logistics of audiovisual installations. UTP cable is significantly thinner, more flexible, and less expensive than traditional shielded audio cable, allowing for easy routing through narrow conduits. Impedance matching and signal balancing protect audio quality from electromagnetic interference (EMI) and radio frequency interference (RFI) along the cable path.
Use cases
-
Corporate environments: Audio distribution in boardrooms and public address systems.
-
Education: Connecting audio from PCs or projectors in classrooms and large auditoriums to central amplifiers.
-
Digital signage: Audio extension for information screens located away from the media player.
-
Residential audio: Distributed (multi-room) audio systems utilizing the home's network cabling.
Frequently Asked Questions
-
Do I need two units for it to work?
Yes, baluns work in pairs (one as a transmitter and one as a receiver). This product is usually sold individually, so you'll need to make sure you purchase a pair or have a compatible unit at the other end.
-
Does the device amplify sound?
No, it's a passive device. It's used to carry the line-level signal, so you'll need an amplifier at the receiving end to connect passive speakers.
-
What type of RCA connector does it have?
The 500027 model features RCA Male connectors mounted on small flexible patch cables, ready to connect directly to the female ports of your equipment.
-
Can I use Cat7 cable?
Yes, although the device is specified for Cat5e/6, it will work correctly with higher category cables, provided the standard pinout is respected.
Project description
Passive stereo audio extension balun designed for transmitting unbalanced line-level analog signals over UTP twisted-pair cabling (Cat5e/6). The device must have an interface consisting of one RJ45 port and two male RCA connectors integrated into color-coded flexible patch cords. Performance specifications must guarantee a bandwidth of 60 Hz to 20 kHz for distances up to 305 meters, and 100 Hz to 20 kHz for maximum distances up to 1.5 km. The unit must offer ground loop isolation and be housed in a compact, flame-retardant ABS enclosure, requiring no external power supply for operation.
