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.
