CYP QU-28S-4K22 1×8 4K HDMI Switching Distribution Amplifier

The CYP QU-28S-4K22 is a professional 1×8 HDMI distribution amplifier designed for high-performance 4K UHD and HDR video distribution across multiple displays. Supporting HDMI 2.0a, 18Gbps bandwidth and 4K@60Hz 4:4:4 8-bit, it can distribute high-quality video and advanced digital audio to up to eight HDMI outputs.

A versatile Group Mode allows the unit to operate as two independent 1×4 HDMI splitters, with each HDMI input routed to its own group of four outputs. This makes the QU-28S-4K22 particularly useful for installations requiring flexible source and display configuration.
