PT-MA-HD42UHD – 4x2 HDMI 2.0 Matrix: Flexible Signal Routing and Audio Integration for Professional AV Environments
The PT-MA-HD42UHD provides matrix switching for four HDMI sources to two independent HDMI outputs, supporting both digital and analogue audio integration. Designed for deployment in meeting rooms, control centres, and hybrid workspaces, this unit incorporates advanced scaling functions and multiple control options for seamless AV signal management. With integrated support for HDR formats and HDCP compliance, the device maintains compatibility with a wide range of display equipment. Flexible audio routing, including ARC and audio de-embedding, enables precise adaptation to diverse installation requirements.

• 4x2 HDMI Matrix Switching: The matrix architecture enables independent routing of any of the four HDMI input signals to either or both HDMI outputs. This configuration supports simultaneous content distribution to dual displays or zones, facilitating dynamic AV setups in collaborative and presentation environments.

• Full 4K60 HDR Support: The unit processes HDMI 2.0 signals at bandwidths up to 18Gbps, supporting resolutions up to 4K UltraHD at 60Hz with 4:4:4 chroma subsampling. HDR10 and Dolby Vision compatibility ensures accurate colour reproduction and high dynamic range for professional display applications.

• Integrated Downscaling Function: The first HDMI output features built-in downscaling, converting 4K content to 1080p where required. This function allows mixed-resolution display systems to operate without signal loss or compatibility issues, supporting legacy equipment alongside modern displays.

• ARC and Audio De-Embedding: Audio Return Channel (ARC) functionality is available on the second HDMI output, enabling audio from the display to be routed back to an external audio system. The unit also provides both analogue (3.5mm) and digital (SPDIF) audio breakaway from HDMI output A for flexible audio distribution.

• Comprehensive Control Interfaces: Control options include web-GUI, RS232, and IR, allowing integration with automation systems or direct user operation. EDID management is incorporated to ensure optimal signal negotiation between sources and displays, minimising compatibility issues during installation or reconfiguration.
