The QU‑4‑8K23 is a 1 × 4 HDMI distribution amplifier (splitter) designed to handle signals up to 8K UHD at 48 Gbps, compliant with HDMI 2.1 and HDCP 2.3. A single HDMI source can be distributed to four displays while maintaining the highest video quality, with support for resolutions up to 8K @ 30 Hz 4:4:4 10-bit and the latest 10-bit and 12-bit HDR formats.
The device supports pass-through of major audio formats, including up to 8-channel LPCM, Bitstream, and Advanced HD Bitstream, and integrates a high-quality DAC that provides a 3.5 mm analog stereo output for quick audio monitoring from LPCM 2.0 sources.
EDID management is simplified with presets selectable from the front panel, allowing you to adapt the source behavior to the capabilities of the connected displays. Front-panel controls and status LEDs provide instant system verification, while the compact form factor facilitates integration into professional and residential AV installations.
