MuxLab IMU-500028-2PK - Analog Stereo Hi-Fi Audio Extender Kit over Cat5e/6 (Pack of 2)
Optimize your professional and home audio setups with the MuxLab IMU-500028-2PK , a ruggedized solution designed to overcome the distance limitations of traditional RCA cabling. This complete kit includes two balun units (transmitter and receiver) that allow you to extend line-level (unbalanced) stereo audio signals over distances of up to 1 kilometer using a single, cost-effective, and versatile Cat5e or Cat6 network cable.
Unlike long runs of coaxial audio cable, which are expensive, bulky, and prone to electromagnetic and radio frequency interference (EMI/RFI), the MuxLab system uses twisted-pair technology to maintain signal integrity. Thanks to its high-fidelity passive design, this extender guarantees a full frequency response of 20 Hz to 20 kHz , ensuring that the sound reaches its destination with the same clarity and richness as it left the source, without ground noise or treble loss.
Each unit features gold-plated male RCA connectors integrated into flexible pigtails, facilitating direct connection to equipment such as DVD players, computers, satellite receivers, or amplifiers, eliminating the need for additional connecting cables at the ends. Its compact, fire-retardant ABS chassis allows for discreet installation behind televisions, furniture, or inside racks, making it the ultimate tool for AV system integrators.
Main features
-
Long-range extension: Crystal-clear audio transmission up to 1 km (3,250 ft) without the need for active repeaters.
-
High Fidelity (Hi-Fi): Full bandwidth from 20 Hz to 20 kHz for faithful and natural sound reproduction.
-
Direct connectivity: Equipped with color-coded (Red/White) male RCA patch cables for immediate "Plug & Play" connection to equipment.
-
Passive Technology: It does not require external power supplies, simplifying installation and freeing up electrical outlets.
-
Noise immunity: The balun design takes advantage of the common-mode rejection of the twisted-pair cable to minimize hum and interference.
-
Durable housing: Constructed from reinforced ABS plastic, designed for durability in commercial environments.
Benefits of the system
The MuxLab 500028-2PK transforms the way audio infrastructure is planned. The main benefit is significant cost savings by using standard network cable (Cat5e/6) instead of audiophile-grade audio cables for long distances. Furthermore, it simplifies cable management in narrow conduits thanks to the smaller diameter of the UTP cable.
For the installer, it offers unparalleled flexibility: it allows for the relocation of source or amplification equipment to secure or centralized locations without sacrificing audio quality in the listening area. Its compact design solves space problems in installations behind flat-screen displays or projectors.
Use cases
-
Distributed audio systems: Ideal for sending music from a central server or PC to amplifiers located in different rooms of a residence or business premises.
-
Classrooms and training rooms: Connecting the audio from a laptop computer on the teacher's lectern to the main public address or amplification system in the room.
-
Digital Signage: Sending synchronized audio to information screens located away from the multimedia player in shopping centers or airports.
-
Conference rooms: Seamless integration of audio sources at meeting tables to distant audiovisual equipment racks.
-
Hospitality and events: Temporary or permanent audio links between bar areas, lounges and DJ booths.
Frequently Asked Questions
-
Do I need to connect the baluns to the electrical current?
No, the MuxLab 500028 is a completely passive device. It operates using the energy of the audio signal itself and requires no external power supply.
-
Can I use Cat6 cable instead of Cat5e?
Yes, the device is fully compatible with both Cat5e and Cat6 cables. Using Cat6 may offer a more robust physical build, although both work perfectly for analog audio.
-
Does the kit include the network cable?
No, the UTP (Cat5/6) cable must be purchased separately in the length required for your specific project.
-
Is it compatible with mono audio or stereo only?
Although it is designed for stereo (two channels), it can be used perfectly to transmit two independent mono signals or a single mono signal if required.
-
What pin configuration does the RJ45 connector use?
Use standard pins for analog audio over twisted pair: Audio 1 (Pins 1 and 2) and Audio 2 (Pins 3 and 6). Ensure the wiring is straight-through (pin to pin).
Project description
Passive analog stereo audio extender kit (balun) consisting of two transceiver units. Designed for transmitting unbalanced line-level signals over Category 5e or higher unshielded twisted-pair (UTP) cabling. Transmission capacity up to 1 km with a bandwidth of 20 Hz to 20 kHz and a total harmonic distortion (THD) of less than 0.007% at 1 kHz. Each module includes two male RCA connectors on 15 cm flexible patch cables and one female RJ45 port. Features a flame-retardant ABS housing and compact dimensions for installation in confined spaces. No external power supply is required.
