Product Overview
What makes the ML-41KVM-ARC-H2
The ML-41KVM-ARC-H2 features four HDMI 2.0 inputs and four USB 2.0 inputs with a single HDMI 2.0 output that supports ARC and CEC functionality. This configuration allows users to switch between four connected systems while maintaining high-quality video output to a single display device.
In addition to video switching, the device includes built-in audio de-embedding capabilities that extract audio from the HDMI signal and route it through two independent audio outputs. These outputs include a stereo analog output and an 8-channel optical SPDIF output, allowing integration with external audio systems such as AV receivers, amplifiers, or professional audio processors.
The switch supports HDMI 2.0 video formats including 4Kx2K resolution at 60Hz with full 4:4:4 chroma sampling and compatibility with 3D video formats. With support for 18Gbps bandwidth, the ML-41KVM-ARC-H2 ensures stable transmission of high-resolution HDMI signals across professional AV systems.
Switching between sources can be performed manually via front panel controls or the included IR remote, automatically based on active signal detection, or sequentially through scan mode. The device also includes built-in EDID management to ensure stable communication between HDMI source devices and the connected display.

Installation
Designed for straightforward professional deployment
The ML-41KVM-ARC-H2 is designed for easy deployment in professional AV installations and IT environments. Its compact design allows it to fit within AV racks, equipment cabinets, or workstation setups.
01
Direct Workstation Setup
Connect up to four computers or HDMI-enabled source devices to the HDMI 2.0 inputs. Connect each system's USB cable to the corresponding USB 2.0 input. Attach a single display, keyboard, and mouse to the output ports. All connected USB peripherals follow the selected HDMI input automatically on switching.
02
AV Rack and Control Room Integration
The compact unit fits within standard AV racks or equipment cabinets. The IR sensor extender provision allows the switch to be installed inside a closed rack while maintaining remote control access from the operator position. The RS232 port enables integration with centralized AV control systems and automation processors already present in the installation.
03
Audio System Integration
The stereo analog output connects directly to AV amplifiers or active speakers. The 8-channel optical SPDIF output connects to AV receivers or professional audio processors for surround sound environments. Audio mode selection between ARC, 2.1, 5.1, and HDMI pass-through is configured to match the connected sound system.
04
Integration with AV Infrastructure
The device can be integrated with additional AV infrastructure components including HDMI extenders, signal distribution systems, AV receivers, and centralized control systems. This makes it compatible with existing professional AV deployments without requiring dedicated or specialist cabling beyond standard HDMI and USB connections.
Where the ML-41KVM-ARC-H2 performs
Suited to professional environments where centralised control of multiple HDMI systems, shared peripherals, and reliable 4K output are required simultaneously.
Corporate Boardrooms
Connect multiple presentation computers and video conferencing systems to a single boardroom display. Switch between sources without disconnecting hardware, with shared keyboard and mouse control for the presenter.
Command and Control Rooms
Operate multiple computing systems from a single operator station. The integrated KVM functionality eliminates the need for separate keyboards and monitors for each connected system, reducing hardware footprint at the operator position.
Broadcast and Production Environments
Switch between multiple video sources feeding into a single broadcast monitor. The audio de-embedding outputs allow independent routing of audio to mixing consoles or monitoring systems while video is handled by the display.
Education and Training Rooms
Connect instructor computers, student workstations, and media players to a single classroom display. Scan mode allows sequential display of sources for demonstration purposes without manual switching.
Professional AV Installations with Audio Systems
The 8-channel optical SPDIF output and stereo analog output enable direct connection to AV receivers, amplifiers, or professional audio processors. ARC support allows audio to be returned from the display back through the HDMI connection.
AV Rack and Equipment Cabinet Installations
The compact form factor and IR sensor extender provision allow the unit to be installed inside closed AV racks or equipment cabinets. RS232 integration enables full control through centralized building automation or AV control platforms.
