4×4 HDMI 2.0 Matrix Switcher with Independent Analog Audio Outputs
KanexPro HDMX44A-18G 4×4 HDMI 2.0 matrix switcher with analog stereo DAC output on every channel. 4K/60Hz 4:4:4, WebGUI, Telnet, RS-232, OSD, 14 EDID…
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.

- 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

Questions
- How many EDID modes does the HDMX44A-18G support per input?
- 14 EDID modes per input: 6 internal, 4 sink-learned, and 4 user-uploaded.
- What audio does the analog 3.5mm output carry?
- Each of the four analog 3.5mm outputs is a DAC stereo output carrying LPCM 2.0 audio, with a max level of 2Vrms and SNR greater than 70dB@0dBFS.
- Can routing configurations be saved and recalled remotely?
- Yes, up to 4 routing presets can be saved and recalled via front panel, WebGUI, Telnet, or RS-232.
- Can the HDMX44A-18G send display control commands?
- Yes, it can send CEC commands per output for Power On/Off, Volume +/-, and Mute to connected displays.
