Source Fader Behaviour
The fader status outputs are active depending on the status of the source fader.
Note that each control surface will behave differently depending on whether or not it supports moving faders.
For surfaces with moving faders, there is a choice of two modes: Normal or Hot Fader (described below). For
surfaces with non-moving faders, there is no choice as the faders
always
operate in the equivalent of Hot
Fader Mode.
The two modes are shown in the diagram below.
·
Normal Mode
– the surface fader position always represents the fader level. This means that if a
source is controlled by RAS or Fader Up/Down/Toggle logic signals, then the surface fader will move in
response to the automation.
·
Hot fader Mode
– the surface fader position is independent of any automation (RAS or fader logic).
This allows an operator to preset a fader value (e.g. 0dB), before an RAS controller or Fader
Up/Down/Toggle fader start opens or closes the Background fader level.
Note that in
Normal Mode
, the Background level is always 0dB and has no action; in
Hot Fader Mode
, the
operator sets the Surface level, while RAS or fader logic signals control the Background level.
