4KMX44-H2

The AV ACCESS HDMI Matrix 4KMX44-H2 is a professional 4×4 HDMI matrix switch that allows you to connect up to four HDMI sources and independently route any source to any of four displays. Designed for commercial AV installations and advanced home entertainment systems, this matrix switch delivers exceptional flexibility, outstanding video quality, and reliable system control.

Supporting HDMI 2.0 and HDCP 2.2, the AV ACCESS HDMI Matrix 4KMX44-H2 provides crystal-clear video at resolutions up to 4K@60Hz 4:4:4. It is fully compatible with HDR10, Dolby Vision, and HLG, ensuring vibrant colors, sharp details, and an immersive viewing experience. The switch also supports premium audio formats including PCM 2.0/5.1/7.1, Dolby TrueHD, and Dolby Atmos for high-quality sound reproduction.

Each HDMI output features a dedicated SPDIF audio output, allowing independent audio de-embedding for multi-zone audio systems. This makes it easy to connect amplifiers, speakers, or AV receivers while maintaining separate audio feeds for different zones.

The integrated 4K-to-1080p downscaler automatically converts Ultra HD content for Full HD displays while preserving native 4K output on compatible monitors. This intelligent feature enables mixed-resolution display environments without additional converters, reducing installation costs and improving compatibility.

The AV ACCESS HDMI Matrix 4KMX44-H2 also includes advanced EDID management with Smart EDID, EDID copy, EDID presets, and EDID writing functions to ensure stable communication between connected devices. Individual audio muting for each SPDIF output provides additional flexibility for professional AV applications.

Control is simple and convenient through multiple options, including front panel buttons, the included IR remote, web-based user interface, and RS-232 serial communication. Firmware updates can also be performed via micro-USB or the web interface, helping keep the system up to date with the latest improvements.

Whether deployed in sports bars, digital signage networks, conference rooms, control centers, educational facilities, or retail environments, the AV ACCESS HDMI Matrix 4KMX44-H2 delivers reliable performance and professional-grade HDMI distribution.
