PFL / AFL Anatomy
Each source supports two independent listen busses for PFL or AFL. The first (PFL 1) is predefined and is always
available. The second (PFL 2) must be assigned from your user-defined busses (via the “
” branch of the 'Tree Definition').
Note that
sapphire
,
sapphire compact
and
POWER CORE
support an additional three listen busses (PFL 3, 4
and 5). These can be swapped with PFL 1 on any fader strip (via the “
" option). This
allows different fader strips to feed different listen bus outputs.
The PFL (or AFL) on/off is usually programmed onto a fader strip MF Key. And each listen bus can feed a
dedicated output, or be switched automatically to your speakers or headphones whenever a PFL (or AFL) is
active. All of these options are defined by the configuration.
PFL Mode
The operation will vary depending on the PFL Mode selected by the operator from the SYS menu. The available
options are:
·
SUM
(default mode) – multiple PFL buttons may be selected. Where faders are closed, sources are
summed onto the PFL Bus; when a fader is opened, PFL is cancelled. Where faders are open, sources
are put into ‘PFL Prepare’ and will be summed onto the PFL Bus once the fader is closed.
·
SUM R
– identical to
PFL Mode SUM
but PFL recurs if you open the fader (cancel the PFL) and then
close the fader. In this mode, PFL is only cancelled by deselecting the PFL button.
·
PFL
– identical to PFL SUM, but PFL buttons intercancel such that only one source may ever be in PFL
or PFL prepare.
·
PFL R
- identical to
PFL Mode PFL
but PFL recurs if you open the fader (cancel the PFL) and then
close the fader. In this mode, PFL is only cancelled by deselecting the PFL button.
·
PFL A
- this mode is called PFL Always and is identical to
PFL Mode SUM
with the exception that it
allows open faders to be put into PFL rather than PFL Prepare.
·
PFL AR
- this mode is a combination of PFL Always and PFL Recurring which means that PFL is never
cancelled by opening a fader.
·
PFL PUSH
– PFL is momentary. This means PFL is active when you press the PFL button, and cancels
on release.
·
PFL DJ
- allows you to prepare a fader level which is applied when you put the fader on-air. Press PFL
and adjust the fader level. Then deselect PFL and press START to put the fader on-air - the fader jumps to
the prepared level. (Note that the prepared level is applied only once. So, if you take the fader off-air, and
then press START again - the fader jumps to 0dB as normal.)
·
AFL
- the channel's PFL buttons operate as AFL (After Fade Listen). The channel's after-fader signal is
routed to the PFL bus. Multiple AFLs may be summed. AFL is only cancelled by deselecting the AFL
button.
·
AFL/PFL
- as for
AFL
, but the channel's PFL signal is heard when the fader is closed; when the fader
opens, the listen bus receives AFL.
PFL Reset
One of the Central Module MF Keys is usually programmed for
PFL Reset
. This provides a handy way of
cancelling all active PFLs across the console.
