Frequently Asked Questions - MTX3-34-M Kramer
How do I switch between inputs on the MTX3-34-M?
You can switch using the front panel buttons, the included infrared remote, or via RS-232 commands. Press the OUTPUT button, then the corresponding INPUT button to route any input to any output.

No, the MTX3-34-M is designed for composite video and stereo audio only. It handles standard analog video signals up to 480i/576i.
What is the maximum video cable length I can use?

What type of audio connectors does it use?
The MTX3-34-M provides terminal block connectors for balanced audio inputs and outputs, and RCA connectors for unbalanced stereo audio, depending on the version. Check your unit's back panel.
Is the power supply built-in or external?
The device features a built-in universal power supply that accepts 100-240 V AC, so you only need a standard IEC power cord.
