4×4 HDMI 2.0 Matrix Switcher with Independent Analog Audio Outputs
Per-Output DAC Stereo Breakout — WebGUI, Telnet, RS-232, LCD & 14 EDID Modes
Standard 4×4 HDMI matrices route video — but when integrators need analog audio at every display zone, they're forced to add external DACs or audio extractors per output, complicating rack design and increasing BOM cost. The KanexPro HDMX44A-18G eliminates that with a high-quality DAC analog stereo 3.5mm output paired to each of its four HDMI outputs, delivering clean LPCM 2.0 analog audio directly to powered speakers or amplifiers without additional hardware.
Supporting 18Gbps bandwidth and resolutions up to 4096×2160@60Hz (4:4:4, 8-bit) with 16-bit Deep Color and HD bitstream pass-through, this matrix handles every current 4K source standard. Comprehensive EDID management covers 6 internal presets, 4 sink-learned EDIDs, and 4 user-uploaded EDIDs. OSD custom text overlay, 4 routing presets, and a full control suite — WebGUI, Telnet, RS-232, and IR — make it ideal for corporate AV, education, and demanding multi-display installations.
- HDMI 2.0, HDCP 2.2/1.x, and DVI 1.0 compliant — 18Gbps on all ports
- Resolutions up to 4096×2160@60Hz (4:4:4, 8-bit); 16-bit Deep Color to 1080p60
- High-quality DAC analog stereo 3.5mm output on each HDMI output (LPCM 2.0 sources)
- HDMI audio pass-through: LPCM up to 8 channels and HD bitstream (Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X)
- 14 EDID modes per input: 6 internal, 4 sink-learned, 4 user-uploaded
- OSD custom text overlay per output — position, size, color, and background transparency adjustable
- 4 routing presets — save/recall via front panel, WebGUI, Telnet, or RS-232
- CEC send commands per output: Power On/Off, Volume +/−, Mute
- Video mute (blank) per output — analog audio unaffected when video muted
- Control via front panel (LCD), WebGUI, Telnet, RS-232 (19200 baud), and IR remote
