AMX Precis PR-0404 4x4 4K60 HDMI Matrix Switcher

The PR-0404 routes any of four HDMI sources to any of four displays at up to 4096 x 2160 at 60 Hz with 4:4:4 chroma, which is the configuration most training rooms and multi-display boardrooms actually need. It is HDCP 2.2 compliant and carries HDR10+, Dolby Vision, and 36-bit Deep Color through without downsampling, and it handles PCM, Dolby, and DTS audio formats over HDMI.

Every output has its own 3-position 3.5mm Phoenix terminal block that de-embeds analog stereo, so each zone can feed a separate amplifier or DSP input rather than sharing one mix. The unit is controlled over Ethernet or RS-232, has a USB Type-A program port, and fits a single rack space at 1.73 inches high by 17.24 inches wide with a screw-down 12V power connector that will not shake loose in a mobile rack.
