PFL key
The headphones monitoring system lets you listen to
any selected input or output signal using stereo
headphones. The signal is selected by pressing a
channel
PFL
switch. This is referred to as PFL (Pre-
Fade Listen) as the signal is monitored before the
fader. This means that the fader has no effect on the
monitored signal and can be turned down to allow
signal checking before raising the level in the mix.
Only one channel can be monitored at a time. The
signal is heard in mono or stereo depending on the
source. Each input, effect and output channel can be
monitored. The headphones are quiet when all
PFL
switches are off. Raise the headphones level control
for comfortable listening level.
☺
Tip We recommend that robust good quality
enclosed ear stereo headphones of 30 to 600 ohms
impedance are used to ensure signal clarity and
continued reliability.

OUTPUT MODE INDICATORS
One of three indicators displays the current AB
output (amplifier) configuration to show which
output mix is routed to each amplifier. The
configuration can be changed using

SIGNAL METERS
The signal routed to each amplifier is displayed on a
10 bar peak reading led meter. These are post fader
and pre AB level control. These meters also display
the PFL signal when selected. Optimum reading is
around 0dB with occasional loud peaks at +6.
PFL ACTIVE INDICATOR
This red indicator lights when any channel
PFL
switch is pressed. The pre fader channel signal is
routed to the headphones and to the signal meters in
mono or stereo depending on the source. The meters
switch to read PFL instead of the AB outputs.
