MuxLab 500219-EU - 2x30W Analog Audio Zone Amplifier over Cat5e/6
The MuxLab 500219-EU is an audio engineering solution designed to radically simplify distributed sound installations in professional and commercial environments. This hybrid device combines the functionality of a high-performance balun receiver with a powerful stereo Class D amplifier , all in a compact and robust chassis. Its design allows it to receive line-level analog audio signals over a single UTP network cable (Cat5e or Cat6) from distances of up to 1 km , eliminating the need for expensive and heavy speaker wire or RCA interconnects susceptible to interference over long runs.
Designed for integrators seeking efficiency without sacrificing quality, the 500219-EU acts as the endpoint of an audio chain, connecting directly to passive speakers via a secure terminal block. By integrating amplification at the point of destination, it allows for the centralization of audio sources (such as matrices or media players) in a technical rack and the distribution of sound to remote areas with minimal and cost-effective cabling infrastructure. Its ability to deliver 30 W RMS per channel at 8 ohms ensures clear, powerful, and distortion-free sound, ideal for providing sound reinforcement in classrooms, meeting rooms, or commercial spaces.
Main features
-
All-in-One Reception and Amplification: Receives audio signal and amplifies it in the same device, saving space and intermediate equipment.
-
Class D Power Efficiency: Offers 2 channels of 30W RMS (at 8 ohms) with superior energy efficiency and less heat generation.
-
Long Range Transmission: Capable of receiving clear audio from distances up to 1 km (3250 feet) using standard Cat5e/6 cabling.
-
Intuitive Local Control: Front panel with volume control, power switch and display of input levels via LED indicators.
-
Ground Loop Isolation: Integrated technology to eliminate hum and parasitic noises common in long-distance installations.
-
Robust Construction: Anodized metal chassis designed to withstand continuous use in demanding environments.
Benefits for the installer and the user
For installers, the MuxLab 500219-EU solves the logistical problem of delivering amplified audio to remote areas. Instead of using large-gauge copper cables that are difficult to run through conduits and expensive, existing network infrastructure or cost-effective UTP cabling can be used. For end users, the benefit lies in the cleaner installation and improved audio quality. Thanks to ground loop isolation, the sound is delivered free of electrical interference, providing a professional listening experience. Furthermore, its volume memory ensures the system returns to the preset level after a power outage.
Ideal use cases
-
Classrooms and Training: Audio amplification of projectors or PCs located far from ceiling or wall speakers.
-
Digital Signage: Sound reinforcement of advertising screens in shopping centers where the media player is located in a server room.
-
Hospitality and Retail: Background music in specific areas (restaurants, shops) controlled from a central office.
-
Residential Multi-room Systems: Audio distribution to distant rooms without loss of quality.
Frequently Asked Questions
What type of cable should I use to connect this amplifier to the source?
Standard Cat5e or Cat6 twisted-pair cable is used. This cable carries the analog audio signal from the transmitting balun to the amplifier's RJ45 port.
Do I need an additional receiver before the speakers?
No. The MuxLab 500219-EU acts as both a receiver and amplifier. You connect the power cable to the input and the speakers directly to the output terminal block.
Is it compatible with any balun?
It is designed to work optimally with MuxLab's family of analog audio baluns, specifically models 500019, 500027, 500028 and 500030, as well as compatible audio matrices.
How is the device powered?
The equipment includes an external power supply that connects to the local electrical network (EU plug) where the amplifier is installed.
Project description
Class D stereo zone amplifier with integrated balun receiver over twisted pair cabling. The device must have an RJ45 input for receiving analog audio signals via Cat5e/6 cable from a maximum distance of 1 km. It will deliver 2 x 30 W RMS output power into 8 ohms via speaker terminal blocks. It will include ground loop isolation, a front-panel volume control with memory, LED level indicators, and a frequency response of 20 Hz to 22 kHz. The chassis dimensions must not exceed 90 x 130 x 50 mm and it must be compatible with standard analog audio balun transmitters.
