If your console uses Style 2 faders please
refer to the description in the Fader Area
section of this manual. Style 2 faders have
a different button layout, and are slightly
different, in the way that the current
assignment, interrogated paths and VCA
groups are indicated.
A and B Layering
Each fader can control two independent
audio signal paths, named A and B. These
paths can be either channels or groups.
Both signal paths are fully equipped with
the same facilities.
Assignable Control
The A and B fader assign buttons
are used to select the channel paths.
Selecting a path causes the central
control panels (Assign panels) to display
and control the settings for that fader’s
channel or group path.
Changes made to the Assign panels
will affect the selected path only. When
switching between the paths, the displays,
LEDs and fader position change to match
the settings of each path.
Path Labels
The label in the display is the name
associated with the paths assigned input,
or the group number if the path is a group.
The input labels default to the Port ID but
can be changed to a more suitable label
using the I/O screens. Path A’s label is
shown in the top half of the display, and
path B’s label is shown in the bottom half
of the display.
If path A is active, the A fader assign
button and the label will be lit in green. If
path B is active, the B fader assign button
and the label will be lit in amber.
Channel or Group Cut/On
The CUT button cuts the channel or
group, its effect is the same as fading it
out completely. There can be ON buttons
here instead, which switch the channel on.
AFL
AFL will be heard in surround through
the monitor loudspeakers (main or small),
if surround panning is in use and the
loudspeaker system is surround.
Indicative LEDs
A set of LEDs next to the assign buttons
give more information about the path.
MR - The fader path is a Master of a
VCA style group
SL - The fader path is a slave within a
VCA style group
ST - The path is a stereo channel or
group
SS - The path is a surround master.
GP - A group is assigned to the path
A - Path A is active
B - Path B is active
The
and Null LEDs illuminate when
the position of the fader is not the same
as the level of the audio. If a VCA Master
is moved away from the `0’ position, the
null leds on the slaves will light to indicate
whether the audio is above or below the
position of the fader.
The T LED indicates that the console
has recognised that the fader has been
touched.
The PEAK LED will illuminate if the
channel or group signal is within 3 dB of
the clipping level.
The ON LED illuminates when the audio
level is not at the
: position.
The EQ, FLTR, DYN and M/S LEDs
indicate that these functions are switched
IN on the selected path (EQ, Filters and
Dynamics settings may be flat).
Fader Bargraph
The fader bargraph indicates the level at
the channel input (post the input gain and
switching and the tone switching), the
channel direct output, or the gain reduction
of the dynamics, indicated by the three
LEDs. Selection is made either on the
Functions panel, or on the USER-CHAN
screen.
PFL
PFL is provided on the fader
overpress and on the button.
It will be heard on the small
LS (or the main LS if PFL to
Mon is selected), or PFL LS
(depending upon how the
monitoring is configured).
VCA Group
Interrogation
Interrogation provides a
clear way of indicating VCA
group assignments.
Interrogation is performed
by holding down the
Assign button of a VCA
group member, the assign
buttons of all members of
the same group will light.
Interrogation of a Primary
Master will light the Assign
buttons of its primary
slaves and secondary
masters.
Interrogation of a
secondary master will light
the Assign buttons of its
secondary slaves, and the
primary master’s Assign
button will flash.
Interrogate Mode - Routing Panel
It is possible to discover which fader paths
are feeding each of the routing busses by
putting the panel into “Interrogate” mode.
INTER
This is done by pressing the INTER button.
If any of the routing buttons (groups,
mains, tracks) are held down, the fader
assign buttons of all the paths feeding that
bus will light. This button can also be used
to interrogate mix minus feeds using the
BUS button on the Input/Output panel.
