8.1 Audio Setup -PAFL
Choose how you want PAFL to work:
Additive mode – Select to listen to more than one
channel at a time. Pressing a PAFL key adds to the
previous selection. When off, the mode is Auto-cancel
to listen to one channel at a time where pressing a
PAFL key cancels the previous selection.
Input/Output PFL (pre-fade listen) – Monitor the signal
before the fader, for example to check it and set its
gain before you bring up the fader. This is the default.
Input/Output AFL (after-fade listen) – Monitor the
signal in stereo after the fader and pan so that you can
hear its contribution and position in the LR mix.
Sel follow PAFL – Link the Sel switch so that pressing
PAFL automatically selects the processing for that
channel.
LR to PAFL – Routes the main LR mix to the monitor
when there is no PAFL selected.
PAFL Delay – Delay the monitor to time align it with
the acoustic sound from the source when the mixer is
a long distance away from the stage. Start with 1ms
per foot.
PAFL Trim – Attenuate the PFL (pre-fade) signal by up
to 24dB to match it with the average AFL (after-fade)
signal which is often much lower than PFL.
