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,
