PT-SP-HD14-48G – HDMI 2.1 4-Way Splitter: High-Bandwidth Signal Distribution with Legacy Support
The PT-SP-HD14-48G is a four-output HDMI splitter engineered for professional AV distribution in meeting rooms, control spaces, and hybrid work environments. Operating at the full 48 Gbps HDMI 2.1 bandwidth, this unit accommodates both modern and legacy HDMI sources, supporting seamless integration across diverse AV infrastructures. Comprehensive EDID management, integrated audio de-embedding, and selectable CEC control facilitate reliable interoperability with a wide array of displays and audio systems. Downscaling capabilities further enhance flexibility, ensuring compatibility with mixed-resolution installations and legacy endpoints.

• 48 Gbps FRL and 8K/4K Support: The splitter transmits signals up to 8K 60 Hz (4:2:0, 12-bit) and 4K 120 Hz (4:4:4, 12-bit), utilising Fixed Rate Link (FRL) for high-bandwidth applications. Full support for VRR, ALLM, QMS, QFT, and SBTM ensures compatibility with advanced AV features required in dynamic professional environments.

• 12-Bit Colour and HDR Formats: Supports 12-bit colour depth, enabling high-dynamic-range formats such as HDR10+ and Dolby Vision. The unit processes RGB, YCbCr 4:4:4, 4:2:2, and YUV 4:2:0 colour spaces, ensuring accurate signal handling for both current and legacy display technologies.

• Audio De-Embedding Options: Integrated digital SPDIF and analogue 3.5 mm outputs allow extraction of audio signals from HDMI streams. This feature facilitates direct routing to external amplifiers or audio processors in conference rooms, auditoriums, or signage systems without requiring additional hardware.

• EDID and HDCP Management: Comprehensive EDID management options and HDCP 1.4/2.3 handshake control ensure reliable source-to-display communication. These functions support seamless integration with a broad range of devices, reducing compatibility issues in mixed-technology AV deployments.

• CEC Switching and Downscaling: A dedicated CEC (Consumer Electronics Control) on/off switch provides precise control over device communication. Integrated downscaling enables 8K to 4K and 8K/4K to 1080p conversion, supporting legacy displays within modern AV systems.
