7 FADER
The 60mm FADER gives you smooth control of the overall signal level in the channel
strip, allowing precise balancing of the various source signals being mixed to the
Master Section. It is important that the input level is set correctly to give maximum
travel on the fader which should normally be used at around the “0” mark. See the
“Initial Setup” section on page 22 for help in setting the right level.
8 PFL
When the latching PFL switch is pressed, the pre-fade pre-mute signal is fed in mono
to the headphones, control room output and meters, where it replaces the MIX. The
PFL ACTIVE LED on the Master section illuminates to warn that a PFL is active. The Left
and Right meters display the PFL signal in mono. This is a useful way of listening to
any required input signal without interrupting the main mix, for making adjustments or
tracing problems.
9 CHANNEL PEAK LED
This LED will light when the signal level approaches clipping at any of the three moni-
tored points: PRE-EQ, POST-EQ and POST-FADE.
10 SIGNAL PRESENT (SP) LED
The SP LED glows when a signal is present. The feed point for the LED is post-EQ, pre-
mute.
11 MIX/GRP
When this switch is up, the channel’s post-fade signal is routed to the Mix (left and
right) buses. When the switch is depressed, the post-fade signal is routed to the
Group (left and right) buses.
