Frequently Asked Questions - MDMX-24 Qtx

How do I set up the MDMX-24 for DMX control?

Connect a DMX controller to the fixture's 3-pin XLR input. Set the DMX address using the DIP switches on the rear panel. Consult the DMX address chart in the manual for proper configuration.

What are the operating modes of this fixture?

The MDMX-24 supports four modes: DMX (external control), Master/Slave (synchronized units), Sound Active (music-reactive), and Auto (built-in programs). Select via the MODE button.

How many DMX channels does the MDMX-24 use?

It offers selectable 2-channel (color macros) or 4-channel (RGBW individual control) modes. Set via DIP switches.

Can I connect multiple units together?

Yes, link fixtures using DMX cables in a daisy chain. Set one as Master and others as Slave for synchronous operation. Up to 32 units can be chained.

What maintenance does the light require?

Keep the housing clean with a soft dry cloth. Do not use liquids. Ensure ventilation slots are dust-free. No internal user-serviceable parts.

How do I replace a faulty LED or power supply?

What safety precautions should I take?

Use the safety cable to secure the fixture when mounted overhead. Do not cover vents. Disconnect power before cleaning. Ensure stable mounting.

The light is not responding to DMX. What should I check?

Verify DMX address settings, cable connections, and terminator if at end of chain. Check that the controller is on the correct universe. Try replacing the cable.

The beam angle is 25°, producing a narrow, focused beam suitable for highlighting objects or stage areas. For wider coverage, use multiple units or diffusion gel.
