What to do if my Qtx Spotlight is unresponsive to DMX?
- DDavid WilliamsAug 4, 2025
If your Qtx Spotlight is unresponsive to DMX, verify the unit is in DMX mode and that the DMX address remains lit, confirming it's receiving a DMX signal. Ensure the DMX controller isn't set to blackout or on the wrong fixture/page. Check the master dimmer value and confirm the correct DMX address is set. Also, inspect the DMX connection and leads.
