Questions
- What is the maximum video specification of the MMX-16X16AUD?
- It routes 16 HDMI 2.0b sources to 16 displays at up to 4K2K@60Hz 4:4:4, 18Gbps bandwidth on every port, with HDCP 2.2/1.x and DVI 1.0 compliance.
- What HDR formats pass through the MMX-16X16AUD?
- HDR10, HDR10+, Dolby Vision, and HLG pass-through, preserving HDR metadata end-to-end.
- What is the exact RS-232 command to route input 3 to output 5?
- Send s in 3 av out 5! over the RS-232 port. The default routing mode is PTP (Point-to-Point).
- How do I enable ARC on output 2 via RS-232?
- Send s hdmi 2 arc 1!. ARC is off by default, and can also be toggled from the WebGUI Output page.
- What is the default IP configuration of the MMX-16X16AUD?
- Static IP 192.168.1.100, subnet mask 255.255.255.0, gateway 192.168.0.1, TCP/IP port 8000, and Telnet port 23.
- How is the MMX-16X16AUD powered and mounted?
- It uses an AC 100-240V 50/60Hz to DC 24V/3.75A power supply, consumes 76.8W, and is a 1U rack-mountable unit measuring 17.3 x 7.9 x 1.7 inches (440 x 200 x 44mm) and weighing 6.8 lbs (3.1kg), with mounting ears included.
- There is no audio from an amplifier connected to a coaxial output, what should I check?
- Verify the coaxial cable is connected to the AUDIO OUT port matching the HDMI output in use. If using ARC, confirm it is enabled via the WebGUI or the RS-232 command s hdmi y arc 1!, and confirm the TV's ARC/CEC output is enabled.
- There is no video on one or more displays, what should I check?
- Use Premium High Speed HDMI cables, keep 4K60 runs to 5m maximum, set EDID to match the display's native resolution, and enable the 4K-to-1080p downscaler for mixed-resolution environments.
- What makes the MMX-16X16AUD suited for rooms mixing legacy audio and new displays?
- It de-embeds audio to a dedicated coaxial RCA port on all 16 outputs and supports ARC, so audio can be extracted for a soundbar or amplifier without external audio breakout hardware.
- Why choose the MMX-16X16AUD for environments with mixed-resolution displays?
- Each output includes an independent 4K-to-1080p downscaler, letting a single matrix feed both 4K and legacy 1080p displays from the same 16x16 routing fabric.
