PFL Button
The PFL button provides two functions:
• Press the PFL button to toggle between Main Out or Sub-Out AFL (LED
off) and channel PFL (LED on).
• Press and hold the PFL button to access all audio channel settings on
the Touch Screen.
Toggling between AFL and PFL
By default, audio signals are output in AFL (After Fader Listening) mode,
i.e. if you change the fader, the volume also changes.
In some cases, you may not want the audio to follow the fader, for
example, if you want to check an audio channel without changing the
adjusted volume. You can achieve this by pressing the
PFL button, which
changes to PFL (Pre Fader Listening) mode. This allows you to hear the
audio signal as it sounds before the fader.
Accessing channel settings
If you press and hold a channel’s PFL button for approximately two sec-
onds, the Touch Screen will display the CHANNEL ADJUST submenu (see
Channel Adjust Submenu on page 99).
