FAQ | If I have a channel set to CUSTOM (APP) on the back of the loudspeaker, but I don’t know where I set the gain to in the QSC Loudspeaker Control App, can I still control the gain from the back of the loudspeaker?

Learn if you can still control the gain on a QSC loudspeaker with a CUSTOM (APP) setting without the QSC app's gain information.

Answer


If there has been an offset between the physical knob and the gain control in the App, you can either:

  • Rotate the gain control on the back of the CB10 loudspeaker to match the same level as the gain in the App to make the physical knob take over again
  • Set the gain all the way to the left (OFF) and turn the level up again. This method avoids unintended jumps in gain level or volume.
