428 Eos Titanium, Eos, and Gio Operations Manual
Holding down the [Fader Control] button while a fader wing is attached will cause the last button
on the wing to toggle between Channel and Fader modes.
Channel faders are LTP or Latest-Takes-Precedence, which means that you can take control of a
channel simply by moving the fader to match the current output level. Channel faders, like the
keypad and level wheel, can then take levels above or below the current playback level.
Holding down [Shift] while moving the channel faders, will allow them to move without changing the
channel levels. This is helpful when you have used your channel faders to record a cue. This allows
you to restore your fades to zero, while leaving the cue values on stage. If you don’t do this, the LTP
behavior will drive the channels toward zero.
