PT-SP-HD24-48G – 2x4 HDMI 2.1 Splitter/Switcher: High-Bandwidth Signal Distribution and Audio Management
The PT-SP-HD24-48G is a professional HDMI 2.1 splitter and switcher designed to facilitate advanced signal routing in AV environments requiring high bandwidth, multi-format compatibility, and precise signal management. Its dual switchable inputs with auto switching and comprehensive EDID handling support seamless integration within meeting rooms, control rooms, and hybrid workspaces. Full support for advanced HDMI features, including VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), QMS (Quick Media Switching), QFT (Quick Frame Transport), and SBTM (Source-Based Tone Mapping), ensures compatibility with a broad range of source devices and display technologies. Integrated audio de-embedding and flexible downscaling capabilities further enhance deployment versatility across diverse AV installations.

• 48Gbps FRL and 8K/4K Support: The unit supports HDMI 2.1 signals up to 48Gbps FRL, enabling 8K at 60Hz (4:2:0, 12bit) and 4K at 120Hz (4:4:4, 12bit). This high bandwidth facilitates uncompressed video distribution in demanding AV scenarios, including large-format displays and high-frame-rate content delivery.

• Advanced HDMI Feature Compatibility: Full support for VRR, ALLM, QMS, QFT, and SBTM ensures optimal synchronisation and latency management. These features are essential for dynamic content applications, such as interactive signage or real-time collaboration systems, where display responsiveness and image quality are critical.

• Comprehensive Colour and HDR Processing: The device accommodates 12bit colour depth and multiple colour spaces, including HDR10+, Dolby Vision, RGB, YCbCr 4:4:4/4:2:2, and YUV 4:2:0. This broad compatibility enables accurate colour reproduction and high dynamic range performance across mixed display fleets.

• Dual Inputs with Auto Switching and Control: Two switchable HDMI inputs with auto switching, CEC button, and RS232 control allow flexible source selection and integration with control systems. This configuration streamlines signal management in multi-source environments, reducing manual intervention and supporting automated workflows.

• Audio De-Embedding and Downscaling: Integrated digital SPDIF and analogue 5-pin Phoenix audio de-embedding provide direct access to audio signals for external processing or amplification. The unit’s downscaling functions (8K to 4K, 8K/4K to 1080p) ensure compatibility with legacy displays in mixed-resolution deployments.
