TRIDENT VECTOR OVERVIEW.
The Trident Vector is a result of extensive research into the operational
needs of today's music recording, post production and television broadcast
environments. The Vector is an in line console employing the latest design
philosophies. We have utilized a unique frame construction which provides
structural rigidity in a low profile, acoustically desirable chassis. All
wiring harnesses are concealed to maintain the modern aesthetics. The choice of
high quality components such as conductive plastic sealed pots, Penny &
Giles faders and gold plated multipin connectors insure extended years of
trouble free performance. Operational attributes of the console are the inline
design with short fader. This provides proper visual identification of monitor
mixes in record and aux send return levels in mixdown. In broadcast mode the
two fader paths provide simultaneous live and multitrack mixes. The I/O channel
has an automute soft switching system with unparalleled implementation.
Automute group masters can internally trigger 12 channel switches. 16 group
masters may be dynamically automated via an external computer. The primary
architecture of the desk includes master status switching with 32 multitrack
busses and eight auxiliary busses. All Vector consoles incorporate four stereo
busses fed from the channel and monitor paths. These provide flexibility for
applications such as sophisticated effects routing for remix projects; Music,
Effects, Dialogues, and Applause for post production. Left Center, Right,
surround film mixing or subgrouping for teleproduction. This is further
enhanced by an A,B,C,D mix buss matrix, and eight track monitor and main stereo
output compressor.

ROUTING AND FRONT END.
The signal through the I/O module has two paths, one controlled by the
channel fader and the other via the monitor fader. Status is globally
controlled but may be changed locally. The 32 group busses are accessed through
the bank of 16 switches. The signal can be fed to busses 1 to 16 and or 17 to
32 by depressing one or both of the Routing Control Switches. The multitrack
routing is always fed from the MTK Pan control. This path feeds the MTK routing
and 4 stereo busses which are selected via the A,B,C,D switches. In Record
status, the pot is fed by the Channel outputs, the Monitor path feeds the Mix
Pan pot and its stereo busses. This flow is reversed in the MIX mode. The
channel path can accept signals from one of three inputs. Mic and Line are
selected globally from the Console Status Master located in the master
facilities section. This may be overridden by depressing the Flip button on the
I/O. The Mic and Line gain controls have ranges of 10 to 70db and plus and
minus 20dB respectively. A 30dB pad and a 48 volt phantom power switch is
provided. The Phase Reversal switch operates on both the Mic and Line inputs.
The third input, Sub group, is enabled by the SUBGRP switch located next to The
Group Trim control. This feature allows the channel to be used as a subgroup
and overrides the Mic Line selection. The output of the group mix amplifier is
fed to the channel path in the Subgroup mode.

AUXILIARIES.
Eight Auxiliary sends are provided on the I/O channel. The first four sends
are mono and have individual level control, monitor path source selection PRE
post fader and cut switches. Aux sends 5,6 and 7,8 are configured as two stereo
pairs with level and Pan pots. MONitor patch source selection, PRE post fader
is provided. Generally, the stereo sends are utilized for headphone feeds but
can be used for a variety of applications that require a stereo signal.
Auxiliary Sends that are selected PRE fader are fed from the INSert return and
follow the INSert PRE post EQ selection. The PRE post EQ switch remains active
regardless of whether the INSert is in or out of the circuit. If sends are fed
post fader they are post the cut switching. The Auxiliary Cut switches can be
externally controlled and automated via the Automute circuitry. However, the
actual switch has priority over the memory.

EQUALISER AND FILTERS.
The hallmark of all Trident designs is the sonic characteristics of the
Equaliser circuitry. Traditional Trident design criteria have been followed
through in the Vector's development. A High and Low Pass filter is provided at
the top of the Equaliser section. Each band is continuously variable and
permanently assigned to the Channel path. The filters have fixed slopes of 12db
per octave and may be switched out of the path by the Filter IN out switch. The
four band parametric equaliser is divided into two sections, the HI LO and MIDs.
The Equaliser resides in the channel path but may be assigned, in sections, to
the MONitor path. This is accomplished by depressing either Hi Lo to MONitor,
or MIDS to MONitor switches. Individual EQ IN/OUT switches are provided for
Channel and Monitor paths.
The IN/OUT switches can be externally controlled and automated via the
Automute Circuitry. However, the actual switch has priority over the memory.
The High EQ Band has a frequency range of 1 kHz to 16 kHz with 15db of boost or
cut. The Low EQ Band is from 30 Hz to 500 Hz also with 15db of boost or cut.
Both EQ bands have shelving characteristics. When the BELL switch is depressed,
the characteristic changes to Peak / Dip. The High and Low Mid frequency bands
are arranged in a fully parametric format. Variable Q (bandwidth) is provided,
on both bands, via a rotary potentiometer. The High mid has a frequency range
of 500 Hz to 8 kHz with 15dB of boost or cut. A times two, X2 switch, doubles
the frequency range to broaden use when splitting Equalisers between Channel and
Monitor paths. The Low Mid frequency band has a frequency range of 60 Hz to 1
kHz. A divide by two switch, changes the frequency range to 30 to 500Hz. These
allow the use of the Midrange equaliser sections over the entire audio spectrum.

CHANNEL AND MONITOR STATUS.
Group Level and Status.
- GROUP. The Group Trim control in its fully clockwise
position is at unity gain. In its fully counter clockwise position it is at
full attenuation for the buss on the associated number module.
- BNCE. In record status the channel path normally feeds
the MTK, multitrack, PAN and routing while the monitor path feeds the MIX pan
and routing. The BNCE, bounce, switch reverses the output routing to
accommodate track bouncing. In mix status the BNCE puts the module into
Broadcast status whereby the monitor path is fed from the channel path, post
filters and pre EQ. when BNCE and GRP are selected simultaneously a post,
channel fader, signal is sent to the monitor path and multitrack routing to
provide additional aux busses during mixdown.
- DIR. Sends the output of the channel path to the same
numbered, multitrack, group output. The DIR (direct) function bypasses the
group output summing amplifier and shortens the signal path.
- SUBGRP. Subgroup is a third input option, in addition to
mic and line, which feeds the group output signal to the channel path input on
modules 1 to 32. Selection of SUBGRP overrides the mic, and line input and
allows the module to be used as an audio subgroup master. The feed is picked up
after the GROUP trim providing input level control for the subgroup master.
- MULTITRACK PAN AND ROUTING. The MTK pan feeds the 32
multitrack busses and the A,B,C,D stereo busses. The MTK pan has a center
detent while the bypass switch insures exact level to odd, even multitrack and
left and right mix outputs.

MONITOR FADER SECTION.
- FDR REV. Fader reverse swaps the channel, long, and
monitor, short, faders. This can also be achieved globally via master status.
The CUT, SOLO, and PFL switches are permanently assigned to the long and short
faders and are not reversed.
- INS PRE. Insert pre selects the insert point to pre or
post EQ, whichever path it is in.
- INS MON. Insert monitor selects the insert point into the
monitor path.
- INS IN. Insert in allows equipment in the insert point
to be bypassed and inserted. This switch can be externally controlled and
automated via the Automute circuitry. However, the actual switch has priority
over the memory.
- SAFE SHRT. Safe short isolates signals on the short fader
from destructive solo modes.
- SAFE LONG. Safe long isolates signals on the long fader
from destructive solo modes.
- TAPE. Selects the multitrack tape return as the source
for the monitor path unless ALL GROUP is selected in the master section.
- GROUP. Selects the group output with the associated
number module to be the source for the monitor path. TAPE & GROUP may be
selected simultaneously to facilitate overdub operations unless ALL GROUP is
pressed in the central facilities section. Selecting TAPE & GROUP
introduces a 6db level drop on punch in. This is to accommodate the two similar
signals.
- READY. Provides switch closures at the rear connector
panel for the ready, record arming of individual tape tracks. The LED may be
driven from the console or tape machine power supply. The READY switch and LED
are physically isolated from each other and the console allowing the use of any
machine combinations.
- MIX PAN AND ROUTING. The MIX pan feeds the mix buss
routing to the A,B,C,D stereo busses. The buss A select switches can be
externally controlled and automated via the Automute circuitry. However, the
actual switch has priority over the memory.
- SOLO, CUT and PFL. Switches are associated with the
corresponding fader rather than the signal path. In fader reverse the long
switches stay with the long fader and short switches stay with the short fader.
The long fader has large illuminated SOLO and CUT switches which are green and
red respectively when engaged. SOLO SHRT and CUT SHRT are associated with the
short fader. SOLO is normally after fader listen except when solo in place,
SIP, is selected in the master facilities section. The long and short fader
have PFL pre fader listen switching in addition to SOLO.

DYNAMICS MODULE.
Four identical Compressor Limiter and Gate Expander sections are fitted into
a standard sized module which can be placed anywhere in the console's frame.
Attenuation and gain reduction meters for each section are located in the fader
panel below the module. The dynamics sections can be patched in to any signal
appearing at the patchbay. The module is arranged in four identical sections.
- COMP. LIM.
The Compressor, Limiter employs a THReshold control which is variable
between plus 20 and minus 20db. A six position RATIO control is selectable from
1.5. 1. to 20.1 LIMiter characteristics and similar RElease selectable from 50
ms to seconds. Push button switches determine whether the compressor is IN, out
of circuit, change the attach time from 20 ms to a FAST ATtacK of O.1 ms and
allow external source triggering with an EXTernal KEY.
- EXP.GATE. The EXPander, GATE is adjusted by a THReshold
control which is variable from plus 10 to minus 40db, a RANGE control which has
up to 60db of attenuation, a six position RELease control is selectable from 50
ms to 2 seconds, and a twelve position HOLD switch selectable from 2 ms to 10
seconds. Push button for IN/OUT, ATtacK time, 20 ms to 0.1ms, and external
keying are provided. A KEY LISTeN switch allows the monitoring of the EXTernal
KEY signal. The DUCK switch sets the GATE to an inverse function for ducking
with the meter measuring gain reduction of the ducked signal. The GATE switch
determines whether the section is set in GATE or EXPand mode.
- FILTER. GAIN. LINK. 15db of boost and cut is available
in a side chain equaliser with the frequency sweepable between 100 Hz and 1kHz
and variable Q, bandwidth. Switches provide X10 capability to change the range
of FILTER frequencies from 1kHz to 10kHz. The COMPressor, GATE switch
determines in which section the filter is assigned. A LINK function permits the
dynamics section below to be LINKed with the one in use.
- GAIN. Finally, a GAIN pot controls the output level of
the dynamics section signal.

CENTRAL FACILITIES SECTION.
The Vector Central Facilities Section CF432 is extremely
comprehensive and is comprised of the following elements.
- OSCILLATOR. A high quality sine wave oscillator providing
6 preset frequencies, a crystal locked 440 Hz square wave for tuning
instruments, and a pink noise generator with level control. The signal is sent
to the patchbay as well as the BUSS and SLATE switches on the panel.
- AUXILIARY METER SELECT. Auxiliary meters are provided on
the meterbridge and may be selected to read Aux pairs, Foldback 1 or 2, Studio
Playback or the AFL,PFL buss output.
- BARGRAPH METER SELECT. When bargraph metering is
installed VU and or PPM characteristics may be displayed. With both VU and PPM
selected the VU is displayed with a single segment indicating PPM level. Red
segments provide overload indication and may be reset via the O,L RESET.
- PHASE METER SELECT. The phase meter provided normally
meters The Control Room Monitors. The meter is switchable to the A,B,C,D and
MAIN busses. It also may be utilised to read the difference between two
signals. The CALibration function may also be used as a tape machine azimuth
detector and a REV PHASE switch is provided. The plus 20 DIFFerential expands
the phase differential for easier viewing.
- TALKBACK SELECT. TALKBACK may be routed to any
combination of auxiliary and foldback outputs. Individual levels for TALKBACK
to STUDIO, AUX, SLATE, and FOLDBACK are provided. The talkback is accessed by
the TALK TO buttons or by using Auto Talkback. Tape machine tallies trigger
AUTO TB and is automatically switched off when the machine is in Play or Record.
A talkback MIC with GAIN control is located in the upper section of the central
facilities section. The TALK TO buttons are located lower and close to the
operator for easy access.
- REVERSE TALKBACK SELECT. Two REVERSE Talkback mic amps
are supplied. Their outputs are selectable to LEFT and RIGHT of the MAIN Output
and, or ALT 1 speaker output.
- STUDIO PLAYBACK SELECT. Selects auxes, foldbacks, stereo
busses, two track machine 1 to 8, mono tape machines 1 to 2, or main output.
Selections are additive and CUT and LEVEL controls are provided.
- AUXILIARY MASTERS. Auxiliary master level controls are
provided for each output with SOLO and CUT switches. The cut switches can be
externally controlled and automated via the Automute circuitry. However, the
actual switch has priority over the memory.
- FOLDBACK SELECT. Each of the two FOLDBACK Masters
provide LEVEL, SOLO, CUT and source selection from the STUDIO PLAYBACK, the
other FOLDBACK, the 4 Stereo Busses, the MAIN Output and the 8 Aux Masters.
Selections are additive.
- MAIN OUTPUT COMPRESSOR. A stereo compressor across the
Main Output is provided. It is switchable out of the circuit if desired.
Controls are provided to adjust THRESHOLD, RATIO, ATTACK, RELEASE and GAIN.
Metering for Input Level and Gain Reduction is provided.
- TWO TRACK REMOTES. Two sets of six switches provide
contact closures for control of stereo tape machine transport functions
including locate.
STATUS MASTERS.
- BROADCAST. Feeds the channel path input to the monitor
path. Very useful in teleproductions. It allows simultaneous generation of live
on air and multitrack mixes.
- ALL GROUP. Overrides the TAPE, GROUP selection on the I/O
Strip. This allows instant group status in monitor path.
- MIC/LINE. Performs a master channel input flip.
- FADER REVERSE. Swaps the channel and monitor path signals
to the alternate fader.
- AUTO BUSS A SELECT. Assigns all appropriate channel and
monitor path outputs to be routed to stereo buss A. This routing may be
cancelled on an individual I/O by pressing their buss A switch twice. The
channel path buss A routing switch can be externally controlled and automated
via the automute circuitry. However, the actual switch has priority over the
memory.
- RECORD. The REC status configures the I/O modules for
tracking and overdubbing sessions. All modules will be selected to mic input,
with the channel, long, fader feeding the MTK PAN and routing. Monitor paths
will be sourced from the selected input, TAPE, GROUP, or BROADCAST, and the
monitor, short fader, will feed the MIX PAN and routing. The monitor path may
be fed to the MTK PAN and routing using bounce, BNCE.
- MIX. The MIX status configures all I/O modules for
mixdown mode. Channel paths are sourced from line input and feed the MIX PAN
and routing. Monitor paths are sourced from TAPE and are fed to the MTK PAN and
routing. The input selections to both paths may be modified using the FLIP,
BouNCE, TAPE, GRoup buttons on the modules or the appropriate master status
switches.
- SOLO LINK. Combines the operation of the long and short
fader SOLO switches when solo in place is selected.
- SIP. Selects all modules between the two solo modes.
Normal solo statues is AFL, after fade listen, which uses a separate buss from
the main output and is non destructive. Both AFL and PFL solo busses may be
adjusted via the AFL,PFL level control. Pressing SIP, solo in place, allows the
channels whose solo switches are pressed to override the mix output by
destructing the remaining signals feeding the mix output. All the other
channels' paths will be cut unless their respective solo SAFE switches are
engaged.
- LOCK.. Disables all other master status switches
preventing any accidental changes in status during recording, mixing sessions or
broadcasts. LOCK sets the solo mode to AFL and disables the oscillator.
Talkback to group and stereo busses is also disabled.
- MON 8TRK MIC. Switches the A.B.C.D stereo faders from
buss output of console to the tape return of eight tracks on a multitrack, an
eight track machine, or hard disk recorder. The outputs from these faders are
then sent to the main buss for mixdown. The feeds to the stereo buss outputs
are maintained at unity gain.
- STEREO BUSS MATRIX. The four stereo busses normally feed
their respective outputs and the Main Output. They may be fed to each other in
any, safe, combination for applications such as video post production or complex
music remixing. Unsafe combinations, A to B plus B to A, are locked out by the
matrix. Control of each buss is provided by SOLO, AFL and CUT Switches. Level
is controlled by a stereo fader for each buss. The CUT switch is located after
the feed to the matrix and patch point. Busses may be selected in and out of
the main mix using CUT without disturbing any matrixed sub mixes or the main
mix. Buss metering is accommodated by ten meters located in the meterbridge and
display the output levels of the four stereo busses and the main buss.
Individual monitoring of the left and right sides of the A.B.C.D and Main busses
may be selected.
- QWERTY KEYBOARD. The QWERTY keyboard is supplied in
Vector consoles fitted with optional fader automation or multiple machine
control. The ASCI- II keyboard contains many real world commands such as GO TO,
CUE, and THEN PLAY for the machine control option. An optional remote keyboard
may be run in parallel with the on board keyboard. This enables assistant
engineers to enter information without upsetting the session in progress.
- AUTOMUTE GROUP MASTERS. These Automute Masters provide
the internal control of 12 I/O switches via the Vector's on board RAM. The
automated I/O switches are as follows: Auxiliary 1 to 4, Auxiliary 5 and 6,
Auxiliary 7 and 8, Monitor EQ in out, Channel EQ in out, Insert in out, A Buss
select, Short fader cut and Long fader cut. In addition to the I/O functions
the auxiliary master 1 to 8 cuts and stereo buss A,B,C,D cuts are also
controlled by the AUTOMUTE circuits. As with all AUTOMUTE circuits the actual
switch has priority over the memory. These switches may be assigned in any
combination to the 16 group masters. Setups are easily created and deselection
is possible from existing groups. Groups may be copied and combined freely from
one to another. Snapshots of existing console setups may be performed. Switch
functions and group masters may be controlled via external computer and software
specifically designed for the Vector console. This allows the Vector's automute
circuits to be directly tied to SMPTE and MIDI addresses.
- MAIN LEVEL. This potentiometer is the main control room
monitor output level. All three outputs MAIN, ALT1, ALT2 follow this level
control.
- MONO. Mixes the left and right monitor outputs down to
mono for left, right phase compatibility checks. This applies to all three
outputs.
- DIM. Reduces the level at the monitor outputs by the
amount set on the DIM LEVEL control. ALT 1, ALT 2, selects the two alternate
speaker outputs. These speaker output levels follow the level of the MAIN
output.
- CUT. Mutes all control room monitor outputs.
- CUT L, CUT R.. Independent left and right speaker mutes
allows single speaker mono operation.
- MAIN BUSS, SOURCE SELECT. Toggles the monitor source
between the main mix buss output and the sources selected in the source select
block. This facilitates quick A,B checking between, for example, the main buss
and the output of a stereo tape machine. Source selection includes eight
external two track sources, studio playback, foldback 1,2, mono 1,2 returns,
A,B,C,D and main busses. All of these may be independently selected left and
right and are additive.
Other facilities located in the master facilities section are,
- MULTITRACK MACHINE REMOTES. Five illuminated push buttons
are provided at the bottom of the central facilities section which are wired as
tape machine transport remote control. If the Vector Machine Control option is
fitted, these become the master transport controls.
- AFL, PFL BUSS LEVEL. Controls the after fade listen and
pre fade listen solo buss levels.
- TALK TO STD, SLATE, FB, AUX. The talkback control
switches the talkback destination between studio, tape machine, foldback and
auxiliary outputs.
- MAIN OUTPUT FADER. Always active and controls the main
output level.
- STEREO BUSS SOLO, CUT. Provided for the A,B,C,D stereo
busses. The stereo buss cut switches can be externally controlled and automated
via the Automute circuitry. However, the actual switch has priority over the
memory.

MACHINE CONTROL.
The optional machine control computer uses current state of the art
technology to provide a comprehensive interface between the engineer and audio,
video and midi recorders. One of its design criteria was to minimize typing and
to provide an intuitive and rapid link between the operator and machine.
Operational speed is achieved by the system's menu driven, point and shoot,
approach. The integral QWERTY keyboard accesses the machine control and may be
utilised in controlling optional fader automation systems. The ability to
locate, punch in and punch out at given bar and beat times lets the recording
engineer forget about long SMPTE time code numbers. The physical link between
the studio computer and the audio, video transport is accomplished by an Adams
Smith Zeta III synchroniser. This supports a direct link to a master machine, a
slave and an external midi sequencer. Additional slaves may be added into the
system.

VECTOR 432 STEREO INPUT MODULE.
AUXILIARY SENDS.
The module is fitted with 8 Auxiliary Sends, arranged as 4 mono sends 1 to
4, and 2 stereo pairs, 5 and 6, 7 and 8.
- MONO AUXILIARY SENDS. The four mono sends are identical
in operation. Each send is provided with a level control, a PRE Post fader
switch, a CUT switch and two switches which allow the operator to choose the
source which will feed the send. If neither the Mono Left nor the Mono Right
switches are pressed, then odd numbered sends will be fed from the left channel
of the module and even numbered sends from the right. If Mono Left is pressed,
the send will be fed from the left channel regardless of its number and if Mono
Right is selected, the send will always be fed from the right channel. If both
are pressed, the send will be fed a mono sum of the left and right channel
signals. These assignments apply regardless of whether the send in question is
being sourced from Pre or post the module fader. The auxiliary CUT switches
may be assigned to the Group Function Master system situated in the console
centre section.
- STEREO AUXILIARY SENDS. The stereo sends are provided
with level and imaging controls, PRE/post fader and CUT switches and a MONO
switch. If the MONO switch is not pressed the odd numbered sends will be fed
from the left channel and the even numbered sends from the right. The
PAN/BALance controls will function as a panpot between the two outputs. As in
the case of the mono sends, this applies whether the sends are selected PRE or
post the fader. The CUT switches for these pairs may also be assigned to switch
groups using the Group Function Master system.
- N.B. If Auxiliary sends are selected post the module
fader, they will be cut whenever the module is cut. If they are selected PRE
fade, they will remain active regardless of the module status.
INPUTS AND MULTITRACK ROUTING.
- MULTITRACK GROUP ROUTING. The 18 switches at the top of
the module control the console's 32 Group Mix busses which are normally fed to a
multitrack tape machine. The signal is derived post the module pan controls,
the left channel feeding odd numbered groups and the right channel feeding even
numbers. Each of the 16 routing switches may feed two groups, in the
combinations shown. The two switches marked 1,16 and 17,32 allow the user to
further control this selection. If only 1,16 is pressed, the first routing
switch will only feed Group 1. If only 17,32 is pressed, the switch will only
feed Group 17, and if both are pressed, the routing switch will feed both Group
1 and Group 17. If neither of the lower switches is pressed, nothing will be
sent to the Group busses. Any number of switches may be selected
simultaneously.
- INPUT SELECTION AND CONTROL. The module is provided with
Microphone and Line inputs, each of which have their own gain control. The MIC
gain control has a range of plus 20 to plus 60dB, split over two ranges, 20 to
40dB and 40 to 60dB. These are selected using the GAIN 20,40 switch, and minus
20dB PAD and plus 48V phantom power switches are also provided. The LINE gain
control has a range of minus 20 to plus 20 dB and is centre detented at the 0dB
position. Input selection is made by the FLIP switch. An InPut BALANCE control
with a range of plus,minus 10dB is fitted and either or both channel inputs may
be phase reversed using the 0 L and 0 R switches. The four switches at the
bottom of this section control the Mono, Stereo matrixing of the input signals.
If none of these switches are selected, the module will be operating in normal
Stereo I.E. The left input will feed the left channel and the right input will
feed the right channel. If the MONO switch is pressed, a sum of the left and
right inputs is fed to both channels. If the MONO Left switch is selected, both
channels will be fed with the left input signal and if MONO Right is selected
both will be fed the right input signal. If both the MONO and MONO Left
switches are pressed, the left channel will be fed a sum of the left and right
inputs and the right channel will continue to be fed with only the right input.
If MONO and MONO Right are pressed the right channel will be fed the input sum
and the left channel will be fed only the left input signal. These switches are
followed in the signal path by the L,R REVerse switch which simply swaps the
signal feeds to the remainder of the module.
METER, INSERT AND OUTPUT CONTROLS.
- METER CONTROLS. If the module is fitted to a standard
I/O module position, only one meter is available. Switches are therefore
provided which allow the user to select the source for this output. The meter
will default to the output of the left channel. If the right switch is pressed,
the right channel will become the source. If the Left plus Right switch is
selected, the meter will be fed a mono sum of the left and right channel output.
In all cases, the meter will read a mono sum of the pre fade, post EQ level if
the module is selected to PFL.
- INSERT CONTROLS. The Insertion point may be selected PRE
and post EQ or POST FADE. A switch is provided which enables the Insert Return
to the module, the Send being active at all times. This Insert IN switch may be
assigned to the Group Function Master system.
- STEREO BUSS ROUTING. The outputs of the module may be
routed to any combination of the four stereo mix busses. Routing is to left and
right of each buss simultaneously.
- A-BUSS SELECT.This switch is controlled by the console's
AUTO BUSS A Status Master switch and may also be used with the Group Function
Master system.
- PANNING AND IMAGING. In place of the more usual
arrangement of a balance control and an image width control, the module is
fitted with two panpots. This allows the operator to produce an image which is
offset to one side of the centre, something which is impossible with
conventional modules. The second, Right, panpot is only active if the PAN switch
is pressed. If the switch is not selected, the Right panpot is disabled and the
Left panpot operates as a balance control between the left and right outputs.
An EXPand switch is provided, the selection of which feeds a fixed amount of
reversed phase signal to the outputs. This can be used to generate an image
which appears to be, outside, the extreme left and right loudspeaker positions.
A low frequency FiLTer switch is fitted to overcome any problems of excessive
cancellation when using the expanded image.
- REMOTE START. A switch and LED are provided which may be
used to control external equipment, cart machine starts,etc. Both are totally
isolated from all console grounds and power supplies, though the LED may be
internally linked to be illuminated from the console supply.
- CUT, SOLO AND PFL. The module is provide with CUT, SOLO,
and PFL switches. The CUT switch may be assigned to the Group Function Master
system. The SOLO is a stereo solo in place unless the console is in AFL or LOCK
modes when it becomes a mono AFL. The module may be selected SAFE from the
destructive SIP mode. The PFL feed is always mono.
EQUALISER AND FILTERS.
- FILTERS. Continuously variable high and low pass filters
are fitted. The slope is fixed at 12dB, octave, and they may be selected In and
out of circuit using the switch provided.
- EQUALISER. All four bands include variable cut and boost
controls giving a range of plus and minus 15dB and continuously variable
frequency sweep controls. The HF and LF sections have a shelving
characteristic. The HMF and LMF sections have variable, Q, controls and are
also fitted with additional frequency select switches. The extra switch in the
HMF section halves the previously selected frequency. The result is that the
two mid band equalisers cover the same frequency ranges as the HF and LF bands,
allowing the use of the SPLIT EQ switch. Pressing this switch assigns the HF
and LF sections to the left channel and the HMF and LMF sections to the right,
thus enabling the operator to use different EQ settings on the two channels.
The equaliser may be selected IN and out of the signal path and this switch may
be assigned to the console's Group Function Master system.

VECTOR 432 ECHO RETURN MODULE.
The MULTITRACK GROUP ROUTING section of the module may be
accessed from any one of the three Echo Return sections using the ER2 and ER3
switches. If neither switch is pressed, the first, top, section of the module
is feeding the routing. If ER2 is pressed section 2 is the source and if ER3 is
pressed, the third, bottom, section is selected.
In all other respects, the Multitrack routing works in the same way as that
fitted to the I/O module.
The Echo Return module provides three stereo returns. The module requires
no additional wiring and plugs into any standard I/O position after the removal
of some patchbay normalling links.
The operational functions are as follows.
- E,R TO AUXILIARY. The six routing switches send the
return signal to the Aux Send mix busses. This signal may then be used for the
creation of spin, effects, or be sent to the two Foldback outputs feeding the
studio headphone systems. If mono Auxiliaries 1 to 4, are selected, they will
normally be sent a sum of the left and right channels, though internal links are
provided to reconfigure individual Auxiliaries so that they are fed with only
left or right signals. The stereo Auxiliaries are sent in the same way as the
Multitrack Routing busses, left to odd and right to even. The feed for this
section can be switched Pre or post the main Level control of the return and may
also be selected Pre or post the Balance control. If the Pre Balance switch is
pressed, the same signal level will be sent to all selected Aux busses. If the
switch is released, the balance between odd and even numbered Auxiliaries will
follow that being sent to the Multitrack and Stereo busses. A Level control and
Cut switch are provided and the Cut switch is assignable to the Group Function
master system in the console central facilities panel.
- EQ. The equaliser is a simple shelving, Bass and Treble,
type as previously used in Trident's TSM and Series 80 console ranges. An EQ
in,out switch is provided which is assignable to the Group Function Master
System.
- STEREO BUSS ROUTING. The output of the return may be
routed to any combination of the four Stereo A,B,C,D, mix busses The A buss
switch is controlled by the console's, Auto Buss A, status master switch and may
also be assigned to the Group Function Master system.
- OUTPUT CONTROLS. The Balance control is provided with an
Expand Image switch which mixes a preset amount of antiphase signal with the
left and right outputs, thus giving a stereo image outside the loudspeaker
positions.
- LF filtering is incorporated. The Echo Return Solo system, is isolated
from the rest of the console solos, so that soloing a long or short fader on the
I/O modules will not cut the returns and soloing a return will cut the other
returns, but not the I/O modules feeding them. A Safe switch is provided to
isolate the returns from this internal solo system. The solo will normally be,
in place, but if the console is selected to its, safe, mode by the SIP or LOCK
status master switches, the Echo Return Solo switches adopt a PFL function which
will send a mono sum of the pre Level control, post EQ signal to the console
AFL, PFL buss. A Level control and Cut switch controlling the return output to
the multitrack and Stereo busses are fitted and the Cut switch may be assigned
to the Group Function Master system.
