18Gbps 8×8 HDMI Matrix with ARC Function

Centralized 4K60 HDMI switching with integrated audio management for multi-display environments. The KanexPro MMX-8X8AUD routes up to eight 18Gbps HDMI sources to eight independent displays at resolutions up to 4K2K@60Hz 4:4:4, with Dolby Vision, HDR10+, and HLG pass-through preserved end-to-end across every output.

Each output provides independent audio de-embedding via both analog (3.5mm) and coaxial (RCA) ports, while per-output ARC support extracts return audio from connected displays. A built-in 4K→1080p downscaler operates independently on each output, enabling mixed-resolution environments from a single matrix. Control options include front panel buttons with OLED display, IR remote, RS-232, TCP/IP, and a full-featured Web GUI with scene presets.
