Product Overview
What makes the ML-102HDA-ARC-4K
The ML-102HDA-ARC-4K accepts one HDMI input from a source device such as a media player, conferencing system, Blu-ray player, gaming console, or presentation PC, and distributes the signal to two HDMI displays simultaneously. Both outputs mirror the same content at identical resolution and refresh rate, without signal degradation.
In addition to HDMI output distribution, the unit deembeds audio from the HDMI input and provides separate digital optical (TOSLINK) and analog RCA stereo outputs. This allows integration with external amplifiers, DSP systems, audio matrices, and sound systems without requiring additional converters.
One HDMI output supports ARC functionality, enabling audio from a connected display such as a smart TV to be routed back through the splitter to external audio equipment. This bidirectional audio capability is particularly valuable in conference rooms and hospitality installations where centralized audio management is required.
The unit supports 4K@60Hz with 4:4:4 chroma subsampling, ensuring sharp text rendering, accurate color reproduction, and professional-grade image clarity. It also includes 3D video format support and output downscaling to 1080P for compatibility in mixed-resolution display environments.

Installation
Plug-and-play deployment for AV integrators
The ML-102HDA-ARC-4K offers straightforward configuration with no software required. Connect the HDMI source to the input port, connect displays to the HDMI outputs, and route audio to the desired sound system via TOSLINK or RCA.
01
HDMI Source Connection
Connect the HDMI output from a source device such as a media player, Blu-ray player, conferencing system, gaming console, or presentation PC to the HDMI input port on the unit. The splitter accepts a single HDMI input and distributes it to both output ports simultaneously at the same resolution and refresh rate.
02
Display and Audio Output Routing
Connect one or two HDMI displays to the HDMI output ports. For audio, connect an optical cable to the TOSLINK output or RCA cables to the stereo analog output and route to the desired amplifier, DSP unit, or PA system. If ARC is required, connect a smart TV to the ARC-enabled HDMI output to return audio through the splitter to external audio equipment.
Where the ML-102HDA-ARC-4K performs
Designed for professional AV integrators working in structured B2B environments where reliable video distribution and flexible audio integration are essential.
Corporate Boardrooms
Distribute 4K presentation content from a single source to dual displays while simultaneously routing audio to a dedicated boardroom sound system via optical or RCA output.
Conference & Collaboration Spaces
Enable ARC functionality for smart display integration with centralized audio systems. Audio from a connected smart TV can be returned through the splitter to external audio equipment without additional cabling.
Hospitality & Retail
Extract audio from HDMI sources to external amplifiers while maintaining synchronized 4K video distribution across multiple displays in lobbies, restaurants, and retail spaces.
Control Rooms & Monitoring Systems
