PT-MA-HD44M – HDMI 2.0 Matrix 4x4: Signal Routing and Audio Extraction for Professional AV Environments
The PT-MA-HD44M is a compact HDMI 2.0 matrix switcher designed to route four UltraHD video sources to four independent displays, supporting high-bandwidth signal distribution in control rooms, meeting spaces, and digital signage installations. Its ultra-compact housing facilitates integration into rack-based or space-constrained AV setups, while multiple control interfaces—including front panel LCD, RS232, IR, and TCP/IP—allow flexible management across diverse deployment scenarios. Integrated audio de-embedding enables simultaneous analogue and digital audio extraction, supporting seamless connection to external sound reinforcement or conferencing systems. The unit accommodates advanced video formats, including HDR10, HLG, and Dolby Vision, ensuring compatibility with modern source and display equipment.

• Matrix Switching of 4 HDMI Signals: Four HDMI inputs can be independently routed to any of four HDMI outputs, enabling flexible signal distribution for multi-display environments. This matrix configuration supports simultaneous or individual source selection, addressing dynamic routing requirements in workspaces, control rooms, or collaborative meeting areas.

• 18Gbps 4K60Hz Video Support: The matrix processes HDMI 2.0 signals at up to 18Gbps, supporting 4K UltraHD resolutions at 60Hz with full 4:4:4 chroma subsampling. High Dynamic Range formats, including HDR10, HLG, and Dolby Vision, are supported for accurate colour reproduction and enhanced visual performance on compatible displays.

• Analog and Digital Audio De-Embedding: Integrated audio extraction provides both S/PDIF digital and analogue stereo outputs. This feature allows direct connection to external amplifiers, DSPs, or conferencing systems, supporting PCM2.0, Dolby True HD, DTS-HD Master Audio, and LPCM7.1 pass-through for comprehensive audio compatibility.

• Multi-Mode Control Interfaces: The unit offers control via front panel buttons with LCD display, web-based GUI, RS232 serial, and IR remote. This range of interfaces enables integration with AV control systems and supports both local and remote management, streamlining operation in fixed or managed AV installations.

• Ultra Compact Enclosure Design: Housed in a 1/2 19” format with a screwable power supply, the matrix is engineered for installations with limited rack space or where equipment density is a concern. The enclosure supports secure mounting and reliable operation in professional AV environments.
