MuxLab IMU-500217-EU - 100W Class D Audio Zone Amplifier with Analog and Digital Inputs
The MuxLab 500217-EU is a professional audio zone amplifier designed to offer a powerful, compact, and extremely versatile solution for distributed sound installations. This device stands out for its advanced Class D architecture, which ensures high energy efficiency and low heat dissipation, allowing it to be placed in confined spaces without compromising performance. Its ability to handle both analog and digital sources makes it the perfect core for high-end residential audio systems, corporate meeting rooms, or commercial environments.
One of the great advantages of this amplifier is its configuration flexibility. It can operate in standard stereo mode , delivering 50W per channel into 8 ohms, ideal for powering a pair of bookshelf or in-wall speakers with crystal-clear sound. Alternatively, for areas requiring higher sound pressure levels or a single-speaker setup, the amplifier can be switched to bridge mode , combining its power to deliver a robust 100W mono channel into 4 ohms . This dual capability allows integrators to tailor the equipment to the specific acoustic needs of each room.
In terms of connectivity, the MuxLab 500217-EU is a true audio management hub. It features three selectable inputs: a stereo RCA line input, a 3.5 mm auxiliary input, and a digital optical (Toslink) input compatible with PCM signals. This facilitates direct connection of modern televisions, media players, computers, or background music systems without the need for additional external DAC converters. Furthermore, it offers comprehensive control capabilities, providing local management via front panel buttons and remote control via IR, RS-232 , and even IP, simplifying its integration into complex automation systems such as Control4 or Crestron.
Main features
-

Class D amplification: High-efficiency technology that reduces power consumption and heat generation, allowing for a compact and durable chassis.
-
Multiple inputs: Versatile source management with integrated analog (RCA, 3.5mm) and optical digital (Toslink) inputs.
-
Total control: Front panel operation options, included IR remote control, RS-232 commands and web (IP) management.
-
Equalization adjustment: Dedicated controls for volume, bass, and treble to fine-tune the sound response to the environment.
-
Cascade design: Loop-out or daisy-chain capability to expand the system to multiple amplifiers.
-
Integrated format: Reduced dimensions with robust metal casing, easy to hide behind screens or mount on technical furniture.
Product benefits
-
Installation versatility: Its ability to switch between stereo and high-power mono allows the same amplifier model to be used for different zones and types of speakers in the same project.
-
Direct digital integration: The optical input eliminates common noise and ground loop problems when connecting audio from modern displays or digital sources.
-
Ease of use: Thanks to automatic or manual source selection and remote volume control, it is ideal for both end users at home and staff in commercial environments.
-
Longevity and reliability: By not relying on noisy fans (convection) and using efficient solid-state components, maintenance is minimal.
Use cases
-
Conference rooms: Audio amplification for presentations by connecting the output of the laptop or videoconferencing system.
-
Classrooms and education: Clear and powerful sound reinforcement for audiovisual material in educational environments.
-
Hospitality and Retail: Background music in bars, restaurants or shops, with enough power to cover background noise.
-
Home Cinema and Multiroom: Extension of audio zones in homes, powering speakers in kitchens, patios or secondary bedrooms with independent control.
Frequently Asked Questions
-
Can I connect a microphone directly?
The unit has line inputs (RCA and jack). To connect a standard dynamic microphone, you would need a microphone preamp or a small mixer before the main amplifier.
-
How do I switch between Stereo and Bridge mode?
The configuration is performed by adjusting the speaker wiring at the output terminal and selecting the operating mode through the control interface or the corresponding switches, as indicated in the installation manual.
-
Is it compatible with 70V speaker systems?
On its own, this amplifier has low impedance (4/8 Ohm). However, MuxLab offers an optional external transformer (model 500755-70V) that allows it to be adapted for 70V lines if the project requires it.
-
Does the amplifier get very hot?
Thanks to its Class D technology, heating is minimal compared to traditional analog amplifiers, allowing it to be installed in spaces with moderate ventilation.
Project description
Compact Class D audio zone amplifier with switchable power output of 2 x 50W RMS at 8 Ohms (Stereo) or 1 x 100W RMS at 4 Ohms (Mono/Bridge). The device must include three selectable audio inputs: 1 x Analog Stereo RCA, 1 x Analog Stereo 3.5mm, and 1 x Digital Optical (Toslink) PCM. It must offer control capabilities via web interface (IP), RS-232, IR, and front panel, allowing adjustments to volume, bass, and treble. The chassis must be metal with approximate dimensions of 148 x 65 x 44 mm, without forced ventilation. It must be compatible with cascading and external power supply.
