Attention!
The attention of the specifier, purchaser, installer or user is drawn to special limitations of use which
must be observed when these products are taken into service to maintain compliance with the above directives.
Details of these special measures and limitations to use are available on request and are also contained in
product manuals.
ATTENTION!
The following special limitations apply to the console and must be observed in order to maintain safety and
electromagnetic compatibility performance:
POWER CONNECTION
The console should only be operated with the power supply connected to ground via its mains supply connector.
CONTROL CONNECTIONS
The console should only be operated with high quality screened control cables. All connector shells should be
of metal construction so that they provide a screen when they are plugged into the console. All DEE connector
shells should be connected to the cable screen. All XLR and DIN connectors should have pin 1 connected to
the cable screen.
AUDIO CONNECTIONS
The console should only be operated with high quality screened twisted pair audio cables. All connector shells
should be of metal construction so that they provide a screen when they are plugged into the console. All JACK
connector shells should be connected to the cable screen. All XLR connectors should have pin 1 connected to
the cable screen.
ELECTRIC FIELDS
If the console is operated in an electromagnetic field that is amplitude modulated by an audio frequency signal,
the signal to noise ratio may be degraded. Degradation of up to 60dB may be experienced under extreme
conditions (3V/m, 90% modulation).
INSTALLATION
There are a number of points to consider when installing a mixing console. Many of these points will have
been addressed before the console is even unpacked but it is worth repeating them.
POSITION
The console should be located in a convenient space commensurate with the use to which the console is being
put. Ideally a cool area is preferred not in close proximity to power distribution equipment or other potential
sources of interference. Provision should be made for some flat surface surrounding the console to prevent
people using it as a table top.
POWER
The power supply should be located as far from the console as the connecting cable will allow. It should be
set for the appropriate line voltage and plugged into the mains outlet using the supplied cable.
THE POWER SUPPLY SHOULD NEVER BE OPERATED
WITH THE MAINS EARTH DISCONNECTED
Please note that the power supply contains LETHALVOLTAGES greatly in excess of the mains voltage and
that its rails can produce extremely large currents which could burn out equipment and wiring if shorted. All
testing and servicing should ONLYbe carried out by qualified engineers.

The 48V switch connects 48 volt phantom
power to the input connector which is
suitable for a condenser microphone
or DI box.
The PAD switch gives 25dB of
attenuation to the input signal which will
allow the connection of high output
microphones or line level signals. If the
input amplifier is transformer coupled
(option) the pad greatly reduces the risk
of saturation at very low frequencies.
The PHASE switch activates a 180
degrees phase change within the input
amplifier.
The PRE switch re configures the direct
output to derive signal from the input
channel pre insert and equaliser. It is
important to note that pre insert direct
outputs are also pre mute.
The treble FREQ control gives
continuous adjustment of the frequency
range that the treble equaliser acts on
from 1k to 20k.
The treble BELL switch converts the
treble equaliser from traditional MIDAS
shelving response to full parametric
operation.
The hi mid FREQ control gives
continuous adjustment of the frequency
range that the hi mid equaliser acts on
from 400Hz to 8k.
The INS switch connects the input insert
return signal to the input channel signal
path.
The EQ switch connects the equaliser
into the input channel signal path.

The GAIN control gives continuous
adjustment of the input amplifier
gain from + 15dB to + 60dB.
The DIRECT output control gives
continuous adjustment of the direct output
level from + 10dB to off. The output is
derived from the input channel post
equaliser pre fader signal.
The TREBLE (dual concentric top)
control gives continuous adjustment of
boost and cut from + 15dB to - 15dB with
a 0dB centre detent.
The treble WIDTH (dual concentric
bottom) control gives continuous
adjustment of bandwidth from 0.1 to 2
octaves with a 0.5 octave centre detent.
This only operates when the BELL switch
is activated.
The HI MID (dual concentric top) control
gives continuous adjustment of boost and
cut from + 15dB to - 15dB with a 0dB
centre detent.
The hi mid WIDTH (dual concentric
bottom) control gives continuous
adjustment of bandwidth from 0.1 to 2
octaves with a 0.5 octave centre detent.
The insert PRE switch arranges the input
channel signal to pass through the insert
point before the equaliser when activated
and after the insert point when not
activated.

The lo mid FREQ control gives
continuous adjustment of the frequency
range that the lo mid equaliser acts on
from 100Hz to 2k.
The bass BELL switch converts the bass
equaliser from traditional MIDAS
shelving response to full parametric
operation.
The bass FREQ control gives continuous
adjustment of the frequency range that
the bass equaliser acts on from 20Hz
to 400Hz.
The HI PASS switch connects the filter
in the input channel signal path before
the insert point and equaliser.

The configurable group MIX controls
(1 to 24) have two functions:-
i. They operate as bus assign ON/OFF
switches by way of a non latching
0
push/push action with LED status
indication.
ii. They adjust the levels sent from the
input channel to the group busses when
in one of the AUX bus modes.
0
The group mix busses can be configured
in three modes:- MONO AUX,
STEREO AUX or POST PAN GROUP.
This is controlled on a bus by bus basis
0
by the global BUS MODE switches on
the GROUP modules. When configured
as mono auxes the left and right controls
give independent level adjustments from
0
+ 6dB to off. When configured as stereo
auxes the left controls perform a pan
function with a constant power (- 3dB)
law while the right controls give
continuous level adjustment from + 6dB
0
to off. When configured as stereo groups
the level control functions are disabled
such that any assigned busses are sent at
unity gain from the channel post fader,
post pan signals.

The PAN defaults to control the channel
placement within a group or master
stereo mix and has a constant power law
i.e. - 3dB at the centre position.
The ST switch connects the post fader
channel signal to the master stereo bus
via the pan control.
The SIS switch enables the spacial
imaging system which operates in
conjunction with the pan and image
controls. It also acts as a left, centre, right
master bus enable overriding any stereo
and mono master bus assignments.
When the spacial imaging system is
active the IMAGE control can modify
the action of the pan control so as to
place the channel within a three speaker
system. When the image control is fully
clockwise the pan control will operate
in full left, centre, right such that a centre
panned signal will route to the centre
speaker only and will not appear in
either of the left or right outputs. When
the image control is fully anti-clockwise
the pan control reverts to stereo such that
a centre panned signal will route at equal
power to the left and right speakers. All
other Image control positions generate a
composite blend of the stereo and LCR
panning systems so that the optimum
degree of center image focus and
speaker power can be obtained. When
the image control and pan control are
both set central the channel will be
routed with equal power to all three
speakers. Constant power is maintained
at all times so that the image can be
adjusted during the show without any
perceived level change.

The SAFE switches disable remote
control of the channels as follows:-
i. The MUTE SAFE removes the channel
mute from the snapshot automation and
automute scenes.
ii. The FADER SAFE removes the
channel fader from the virtual fader
automation and VCA master fader
control including vca mutes.
iii. The AUTO SAFE removes the
channel from the snapshot automation
system only; leaving the automutes,
VCA masters and assignment systems
active.
The SET switch is used to programme
the channel automute and VCA master
assignment. The central controller
MODE and ASSIGN keys select the
desired automute or VCA group and the
SET switch will toggle the channel on
and off with each alternate press.

solo
The SOLO switch sends the input channel
signal to the PFL mono and AFL stereo
busses. If the switch is pressed for a short
time it will latch on or off, but if it is held
on for more than 1 second the latching is
disabled and when the switch is released
the channel solo will turn off. As a default
the solo system is auto cancelling so each
new solo cancels the last. This function is
time dependant which allows several solos
to be active as long as they are switched
on at approximately the same time. The
SOLO ADD MODE switch on the
MONITOR module defeats the auto
cancelling and allows multiple channel
monitoring. In this mode input solos have
priority over outputs and will temporarily
override any active output solos. The
input solos also override any active VCA
solos.
The FADER gives continuous adjustment
of the input channel level from
+ 10dB to off.
The STATUS leds are used to show
fader positions and the status of VCA
and MUTE group assignments. The
central controller MODE switches toggle
through the four available states:- VCA
group assignment, MUTE group
assignment, FADER position manual
recall and null, and full automated
VIRTUAL FADER RECALL.
FADER MANUAL RECALL AND NULL
In this mode, the STATUS LEDs are used
to prompt the operator where to move the
fader. If the fader is not at the position
stored in the current recalled snap shot,
one/two LEDs will flash to indicate
where the fader should be. A single
flashing LED indicates that the fader
should positioned next to that LED, if
two LEDs are flashing the fader should
be between the two LEDs. As the fader is
moved closer to the required position the
LED(s) will stop flashing and will be
replaced by a single continuously lit
LED. Once the fader is at the correct
position all LEDs will extinguish.

FADER POSITION CHECK
When a scene's contents are being
"checked" (see automation operation) the
STATUS LEDs will indicate the fader
position stored in the scene by
continuously illuminating one or two
LEDs as appropriate.
VIRTUAL FADER RECALL
When in VIRTUAL FADER mode (see
automation operation) the automation
system will generate a "virtual" fader, set
to the level of the input fader at the time
the snap shot was stored. The level of the
virtual fader is added to the level of the
physical input fader. In this mode the
STATUS LEDs indicate the "position" of

The left and right PAN controls are used
to place the input channel signals within
a stereo group or stereo master mix. As
well as image placement, the controls
can also adjust the image width from
stereo through mono to reverse stereo
(left and right crossed over). The controls
have a constant power law i.e. -3dB at
the centre position.
The ST switch connects the post fader
channel signals to the stereo master bus
via the pan controls.
The MUTE switch mutes the input
channel at all points after the insert send.
The switch can be controlled from
snapshot automation and by automute
scenes.
