MuxLab IMU-500553 - 2-Channel 240W Dante Power Amplifier - Compact Network Audio Solution
The MuxLab IMU-500553 represents a significant evolution in professional audio distribution, combining robust power amplification with the flexibility of audio-over-IP technology. This Class D amplifier has been meticulously designed to integrate seamlessly into Dante ecosystems, allowing it to receive digital audio signals directly from the network and convert them into powerful, crisp analog outputs. It is the ideal solution for installers and technicians looking to simplify cabling without sacrificing sound quality or output power.
With a total capacity of 240W , this device stands out for its operational versatility. It can be configured to work in stereo mode, delivering 120W per channel in low-impedance systems (4 or 8 ohms), or in bridged mode to power high-impedance speaker lines at 70V or 100V with the full 240W. This flexibility makes it an all-rounder, suitable for everything from distributed background music systems with multiple ceiling speakers to high-performance stereo setups in conference rooms.
Its physical design is equally impressive. With a half-rack (1/2 rack) form factor, it saves valuable space in the patch panel. Furthermore, its fanless architecture ensures completely silent operation thanks to natural convection cooling, making it ideal for local installations where equipment noise could be intrusive, such as classrooms or noise-sensitive meeting rooms.
Main features
-
Flexible power: Configurable as 2 x 120W (4/8 Ohm) for stereo or 1 x 240W (70V/100V) for PA systems or background music.
-
Native Dante integration: Receives pure digital audio via an RJ45 port, eliminating the interference typical of long analog cable runs.
-
Processing and control: Includes a switchable 80Hz high pass filter and gain adjustments to optimize the signal according to the type of speaker connected.
-
Energy efficiency: Meets Energy Star standards, automatically entering standby mode after 15 minutes without a signal, with a consumption of less than 0.5W.
-
Silent design: Natural cooling with no moving parts, eliminating background noise and fan maintenance.
-
Advanced protection: Integrated circuits protect against short circuits, overheating, and overcurrent to ensure a long service life.
Benefits of Dante technology in amplification
Implementing Dante in the MuxLab 500553 transforms how audiovisual systems are designed. By utilizing existing network infrastructure, the cost and complexity of heavy copper cabling are drastically reduced. Management is centralized through the Dante Controller software, allowing any network source to be routed to this amplifier with a single click. This offers unprecedented scalability: adding a new audio zone is as simple as connecting a network cable.
Ideal use cases
-
Conference and meeting rooms: Thanks to its quiet operation and compact size, it can be discreetly mounted under a table or behind a screen, feeding the room's speakers with crystal-clear audio from Dante microphones.
-
Retail and Catering: Perfect for handling 70V/100V lines, distributing uniform background music in large areas or multiple dining areas.
-
Classrooms and Training: Its automatic power-on capability and 12V trigger control facilitate automation in educational environments, turning on only when the classroom AV system is active.
-
Digital Signage: Provides the necessary sound reinforcement for remotely managed information or advertising displays.
Frequently Asked Questions
Can I connect 100V speakers directly?
Yes, the amplifier supports bridged mode which allows you to connect constant voltage speaker lines of 70V or 100V using the full 240W power output.
Do I need an external Dante decoder?
No, this amplifier has a built-in Dante card. You only need to connect the RJ45 network cable and route the audio from the Dante Controller software.
Does the equipment make noise when it's running?
No, the MuxLab 500553 uses natural convection cooling and has no fans, so its operation is completely silent.
How is the power on and off managed?
The device features audio detection and intelligent power management. It goes into sleep mode if no signal is detected and automatically wakes up upon receiving audio. It also has a 12V trigger input for external control.
