How it works
The IDCA stores the ratios of the levels of the assigned channels. When a channel level is changed, the ratio is recalculated. By changing the IDCA fader, all assigned channel levels will be adjusted according to the stored ratios.
The red line behind the fader knob of an IDCA shows the minimum/maximum levels of the assigned channels.
