DVDO-Matrix-44-Mini is a compact 4x4 HDMI matrix switcher. In addition to basic functions such as cross-point switching and control (IR, RS-232, IP), it also features advanced functions like auto-downscaling for each HDMI output when it is connected to a 1080p display. There are SPDIF audio breakouts for each HDMI output, to provide more audio feeds to a multi-zone audio system.
