PT-C-HDM – HDMI 2.0 Signal Manager: In-Line Signal Control and Compatibility for AV Integration
The PT-C-HDM in-line HDMI manager is engineered to address signal management requirements in professional AV environments such as meeting rooms, control spaces, and hybrid workstations. Its compact, passive design integrates directly into HDMI signal paths, providing advanced control over EDID negotiation, HDCP compliance, and CEC behaviour. The unit enables reliable connectivity and system interoperability, particularly where mixed-generation display hardware and source devices are present. Flexible configuration options support seamless adaptation to diverse installation scenarios, ensuring stable video performance and system reliability across a range of deployment contexts.

• 18Gbps Throughput and HDCP 2.2: The PT-C-HDM supports HDMI 2.0 bandwidth up to 18Gbps, accommodating 4K 60Hz 4:4:4 video signals with full HDCP 2.2 compliance. This ensures compatibility with current UHD sources and displays, maintaining secure content transmission in professional AV applications.

• Comprehensive EDID Emulation: A selectable range of EDID emulation settings enables precise control of signal negotiation. The unit supports common HD and UHD resolutions, as well as custom and pass-through configurations, facilitating integration with a wide array of source and display devices.

• Dip Switch HDCP Handling: HDCP processing is managed via a dedicated dip switch, providing stable handshake connections between devices. This hardware-based approach reduces the risk of authentication failures and simplifies troubleshooting in complex signal chains.

• Dedicated CEC On/Off Switch: A unique CEC (Consumer Electronics Control) switch allows installers to enable or disable CEC signal transmission. This feature enhances system integration flexibility and mitigates unintended device interactions in multi-zone or shared AV environments.

• Automatic 4K to 1080p Downscaling: Integrated downscaling functionality automatically converts 4K signals to 1080p output. This ensures optimal video reproduction on legacy displays, supporting mixed hardware deployments without manual intervention or signal loss.

Reliable Signal Management for Mixed AV Systems
The PT-C-HDM delivers essential HDMI signal control, supporting stable EDID negotiation, robust HDCP handshakes, and flexible CEC management. By combining automatic downscaling with hardware-based configuration options, the unit enables seamless integration of new and legacy devices within demanding AV installations.
