DVDO-Matrix-44-Mini 4x4 HDMI Matrix with Audio Outputs User Manual DVDO
Introduction
Overview
The DVDO-Matrix-44-Mini is a 4x4 compact 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.
Features
4 HDMI Inputs and 4 HDMI Outputs.
All HDMI inputs and outputs support HDMI with HDR formats including HDR
10, HLG, DOLBY VISION up to 4K60 444.
HDCP2.2 compliant.
With built-in 4K-1080p downscaler for each HDMI Output, the matrix can
downscale 4K 60Hz 444 to 1080p@60 444. 4K downscaler can work
automatically when the matrix is connected to a 1080p display or can be set
to ON/OFF by API commands.
Each HDMI output has a SPDIF audio breakout, and supports formats up to
5CH HBR or 2CH PCM audio.
Supports smart EDID; each input can be assigned to smart EDID mode.
Supports EDID presets, EDID copy and EDID write. By default, each input
EDID is set as 4K60 444 HDR with 5.1CH encoded audio.
Supports audio mute; four SPDIF outputs can be muted separately by API
commands.
Supports upgrading firmware via both micro-USB and web UI (for MCU and
web module).
Rich control options, include RS-232, IR, web UI and front panel buttons.
