1 × 4 4K @ 60 4:4:4 HDR HDMI distribution amplifier with HDCP engine, EDID tools, down‑scaling, CEC system reset

The QU‑4‑4K22 is a 1 × 4 HDMI distribution amplifier designed to handle video signals up to 4K UHD 18 Gbps, including 10- and 12-bit HDR, 4K @ 60 Hz 4:4:4 and 3D content. HDMI sources can be distributed simultaneously to four outputs while maintaining the highest video and audio quality, with support for LPCM 7.1, Bitstream, and Advanced HD Bitstream.

Each output features an independent HDCP engine, ensuring stability even when using displays with different capabilities. The system can automatically apply 4K to 1080p downscaling or color space conversion (4:4:4 to 4:2:0) based on the EDID requirements of each connected display. The unit also supports active source CEC control for periodic resetting of input selection on compatible displays.

Control of the main functions is via front-panel switches with LED status indicators, simplifying visual verification of operation in installations and multi-display AV systems.
