Module width is 1.25"
Dimensions:

The TR DENT 88 nput module is an extremely sophisticated and
flexible channel that can be used for recording, mixing and
monitoring multi-track recordings. t will accept a signal from a
low impedance balanced microphone, high or low level balanced
line input, or even the output from a musical instrument.
t provides the user with state of the art fully discrete
microphone preamps, with the option to add transformers to as
many channels as you like. A four band fully sweepable Trident
EQ is at the core of this console, every channel also has a Tilt EQ
on the Monitor section with the ability to swap the full EQ and Tilt
EQ from the nput path and the Monitor path.
Access to the channel is available through means of a
switchable post Mic preamp insert and a switchable pre/post EQ
insert point. This allows the user to insert their favourite external
Mic Preamp (or Line output device) into the channel and remove
the internal preamp and additionally insert an effects device via
the standard channel insert.
Eight Auxiliary sends are provided, four mono and two stereo
sets, each can be switched pre or post the channel fader. Aux 1,
Aux 2 and Aux 7/8 can also be selected between the channel
and monitor path, greatly adding to the flexibility of the module.
Each module incorporates a monitor section with the Tilt EQ
which is used to monitor a replay channel from a multi-track
recording device. This is, in effect, a separate signal path which
ultimately feeds the master Left/Right outputs. By making the
channel EQ and Auxiliary sends 1,2 and 7/8 to this path , this
becomes an extremely versatile feature of the console. When
monitoring the output of a multi-track recording device, it is
possible to create a monitor mix with equalisation and reverb ef-
fects completely independently from the channel. These effects
would also remain when the recording is played back through
the same monitor section.
When the module is used for mixing purposes, the monitor sec-
tion functions as an additional line input return to the main
Left/Right mix, again with the Tilt EQ and Auxiliary 1,2 and 7/8
available through the monitor section. This effectively doubles
the number of inputs per input module that are available on mix
down mode. This, with additional inputs on the master section,
greatly increases the inputs available, even on the
smallest console.
The input channel is provided with a switchable non destructive
mono pre fader listen (PFL) and stereo after fader listen (AFL)
SOLO system, the monitor input is provide with an AFL SOLO
only. t is possible then to hear the selected signal in isolation (or
mixed with other “soloed” sources) separately in the main moni-
tors, without effecting the main Left/Right mix.
The images on the following pages give a brief description of the
controls on the nput module:
The Input Module
TRIDENT 88 OWNERS MANUAL

1-2 Group Assignment
Assigns the Channel post-fader signal to
the Group 1 and 2 mix buses through the
Channel Pan Control. With the Channel
Pan control in mid position, the signal will
be fed to Group 1 and 2 in equal
amounts. If the Channel Pan Pot Control
is positioned fully anti-clockwise (ACW)
the channel signal will only feed Group 1.
When positioned fully clockwise (CW) the
signal will feed only Group 2..
5-6 Group Assignment
Assigns the Channel post-fader signal to
Group 5 and 6 mix buses through the
Channel Pan Control. Operation is the
same as the 1-2 Group assignment.
3-4 Group Assignment
Assigns the Channel post-fader
signal to Group 3 and 4 mix buses
through the Channel Pan Control.
Operation is the same as the 1-2
Group assignment.
7-8 Group Assignment
Assigns the Channel post-fader
signal to Group 7 and 8 mix buses
through the Channel Pan Control.
Operation is the same as the 1-2
Group assignment.
L-R Mix
Assigns the Channel post-fader signal to
the Left and Right mix buses through
the Channel Pan Control. Operation is
the same as the 1-2 Group assignment.
Sometimes referenced as the Main mix
or Remix bus assignment. In a multi-
track studio environment, this L-R Mix
assignment and the Channel Monitor
Input allow the user to have two sepa-
rate external inputs (Channel Mic/Line
and Monitor return) that can be sent to
the Left and Right mix busses, effec-
tively doubling your inputs on

TRIDENT 88 OWNERS MANUAL 5

Trident 88 Input Channel
Mic/Line Options
MIC INSRT
Selects between the Mic input source on the XLR /
¼” Combination connector and the line level input
(labelled Ext MIC) that feeds the Channel. Allows
the user to connect a line source (external Mic
Preamp) and be able to bypass the Channel Mic
pre-amp stage or switch between them.
+48V
When depressed , provides +48 Volt phantom
power to the XLR portion of the MIC input connec-
tor. Note: +48V will NOT appear on the ¼” part of
the MIC input connector. Phantom power is required
for operation of many condenser microphones. See
your microphone instructions to see if phantom
power is required or should not be activated (some
microphones require phantom power NOT to be
activated or they may be damaged).
MIC GAIN
This control adjusts the amount of
gain of the signal connected to the
MIC XLR / ¼” Combination connector.
For low impedance balanced micro-
phone plugged into the XLR the gain
varies from +5dB min to approximately
+60dB. For a line level plugged into
the ¼” part of the MIC combination
connector the gain varies from -15dB
to +40dB, effectively providing a 20dB
pad to the microphone preamp.
Note: This gain is independent from
the Line Gain.
Line Gain
This control adjusts the amount of gain
of the signal connected to the TRS LINE
jack. In the mid position the gain is
unity (0dB).
Line Switch
This control adjusts the amount of gain of the signal
connected to the TRS LINE jack. In the mid position
the gain is unity (0dB)
POL
When depressed, it reverses the electrical input
polarity of any microphone or line level input signal
which has been selected as the channel source. Use
of this control may alter the sound quality of an input
relative to other channels when multiple
microphones are picking up the same sound.
CHAN MTR
This button selects the signal that is fed to the
relevant channel meter situated on the meter bridge.
In the up position the Channel Direct Output feed is
displayed.
[The Channel Direct Output can be user defined by a
selectable option on the Input module, it can be
selected either Channel post fader or Channel Insert
Return (signal appearing on ring contact of Channel
INSERT TRS jack.]
When this button is depressed the channel meter is
fed from the signal on the Channel MONITOR I/P TRS
jack.
In a multi-track studio environment where the Chan-
nel Direct Output is fed to the recording device and
the output of this device is connected to the MONITOR
I/P, it is possible to see on the Channel meter what is
sent to or received from the recording device.
I/P REV
The Input Reverse switch when
depressed flips the Line Input signal
and the Monitor Input signals. In effect
this switch determines the Line input
source that is available to the channel.
Combining this with the Line Switch
above allows the user to source the
channel signal from the Channel
Monitor Return TRS jack and to use the
full channel strip resources for the
Monitor return signal. Alternatively
depressing this switch selects the Line
Input TRS source for the Channel
Monitor section.

CHANNEL EQUALISER
A four band fully sweepable Trident EQ with overlapping
ranges is provided with a switchable high pass filter. The
HIGH and LOW sections of the equaliser have a shelving
response and the mids have a peaking (bell) response.
HIGH Frequency Section – Shelving
Adjusts the high frequency shelving EQ response.
The Frequency control selects the corner frequency
of the shelving filter (between 1kHz and 15kHz)
and the Level control adjusts the cut/boost
between +/- 15dB. The centre “0” position of the
Level control has a detent to indicate that it is
having no effect on the associated channel signal.
Cut or boost of the high frequency level control is
usually used for minor tonal adjustments.
HIGH - MID
Adjusts the high-mid frequency EQ response.
The Frequency control selects the centre
frequency of the filter (between 700Hz and
10kHz) and the Level control adjusts the
cut/boost between +/- 15dB. The centre “0”
position of the Level control has a detent to
indicate that it is having no effect on this
frequency band. The bandwidth of this filter is
approximately one octave. The high-mid
frequency controls are used for minor tonal
adjustment or repair of a specific band of
frequencies.
LOW –MID Frequency Section
Adjusts the low-mid frequency EQ response. The
Frequency control selects the centre frequency of the
filter (between 100Hz and 1.5kHz) and the Level
control adjusts the cut/boost between +/- 15dB. The
centre “0” position of the Level control has a detent
to indicate that it is having no effect on this frequency
band. The bandwidth of this filter is approximately
one octave. The high-mid frequency controls are used
for minor tonal adjustment or repair of a specific
band of frequencies.
LOW Frequency Section – Shelving
Adjusts the low frequency shelving EQ response. The
Frequency control selects the corner frequency of the
shelving filter (between 40Hz and 650Hz) and the
Level control adjusts the cut/boost between +/-
15dB. The centre “0” position of the Level control
has a detent to indicate that it is having no effect on
the associated channel signal. Cut or boost of the
low frequency level control is usually used for minor
tonal adjustments.
EQ IN
This switch inserts the 4-band EQ and High
Pass Filter into the channel/monitor (see EQ
TO MON switch description below) signal
path. When not in use, it is suggested that
the EQ be kept in the OUT position for best
phase performance.
INSERT ON
When depressed, this switch places the rear
panel channel TRS insert connector in line with
the signal path. "This insert point is by default
after the channel EQ (unless it is selected pre
EQ below). By routing the signal through this
connector, the insert may be used for
applications such as an effect that can be
switched in/out. In the event the user wants to
patch in his/her favourite external EQ, it can be
connected to the Channel insert TRS and
activated with this switch, it could be used in
conjunction with/without the Trident EQ.
HPF
When selected inserts a high-pass (or Low-
Cut) filter with a corner frequency 50Hz and
a roll off rate of 18dB per octave into the
signal path. This control is used to remove
unwanted signal content below 50Hz. The
result is usually improved signal quality of
the associated input signal, while decreasing
the low frequency amplification demand of
the audio systems amplifier and speaker
combination. Mainly for use with micro-
phones, this helps remove low frequency
rumble and handling noise.

TILT EQ
MON TILT EQ Control
A single control level which simultaneously adjusts the
low and high frequency gain of the signal. In the full
counter clockwise position the low frequencies are
boosted whilst the high frequencies are cut, in the
centre position there is no effect on the signal and in
the full clockwise position the low frequencies are cut
and the high frequencies are boosted.
Note: There is no TILT EQ on/off switch and the TILT EQ
is always in circuit.
MON PAN (Monitor Pan) Control
This control blends the post monitor level signal between
the Left and Right buses. When at the centre, detented
position, both Left and Right buses are fed equal
amounts of signal (each down by 3dB).
MONITOR LEVEL Control
Adjusts the monitor signal level to the
Left/Right bus
EQ to MON
Assigns the 4 band channel EQ to the
Monitor Section, the TILT EQ is then inserted
to the Channel path. Note: this switch is not
illuminated.
SOLO (AFL)
When pressed, routes the monitor (post level
and pan) signal to the Solo bus.
Additionally this switches the Main Monitor
Output (normally fed the Left/Right Mix) to
source the signal from the AFL/PFL Master
Level in the Master section as well as to
trigger LED indicators in the Master section
and Meter-Bridge stating a solo has been
pressed.
MONITOR MUTE
When pressed will Mute the monitor signal
to the Left/Right bus. It is recommended
when the monitor section is not being
used that it be muted
Channel Signal Indicators
+10 – Indicates RED when the channel signal level has
reached +14dBu (+10 VU)
-20 – Indicates GREEN when the channel signal level has
reached -16dBu (-20 VU)
The channel indicator signal source can be selected pre or
post the channel fader through an option available on the
input module circuit board.
(Note: Signal headroom available on the input module is
+22dBu and when the +10 indicator illuminates the signal
level is approaching 6 to 8 dB before clipping when just
flashing red with signal peaks).
These are extremely useful features and provide a constant
indication that a signal is present in the module (green LED)
and that the signal peak is being reached (red LED).
AFL/PFL Select
Selects the channel source feed that will be fed
to solo bus when the Channel SOLO is pressed.
UP - solo system is fed from the channel post
fader/post pan pot point and is a stereo
signal that follows the pan pot. This allows the
user to monitor the channel in the solo system
and to see its contribution to the mix.
Down - solo system is fed from the channel pre
fader point and is a mono source. This
allows the user to monitor the signal in the solo
system before the channel fader/mute, allowing
the user to check the signal in the channel
without being routed to any output buses.
Channel PAN Control
This control blends the channel post-fader/post mute signal
between any of the assigned bus pairs (L-R Mix, Group 1-2,
Group 3-4, Group 5-6 and Group 7-8) located at the top of the
module. When at the centre, detented position, both sides are
fed equal amounts of signal (each down by 3dB).
SOLO (Channel)
When pressed, routes the channel AFL or PFL
(see AFL/PFL Select above) signal to the Solo
bus. Additionally this switches the Main
Monitor Output (normally fed the Left/Right
Mix) to source the signal from the AFL/PFL
Master Level in the Master section as well as to
trigger LED indicators in the Master section
and Meter-Bridge stating a solo has been
pressed.
MUTE (Channel)
When pressed will mute the aassigned outputs of the
channel (Group1 – 8 and L-R Mix) and all post Aux sends.
The Mute does not affect the channel’s solo PFL feed, but
WILL affect the channel metering in the Meter Bridge, the

TRIDENT 88 OWNERS MANUAL 9

The Group section of the console greatly enhances
the flexibility of the TR DENT 88 console and pro-
vides a number of different functions. There are 8
Group modules provided on the console, each
controlling the associated group mix bus outputs.
The groups can be used as audio subgroups for
combining and processing a collection of input
channels. Each group bus has its own TRS nsert
jack and TRS balanced Output jack on the rear
Master Connector panel.
The Group module also provides a method of
monitoring, equalising and panning the group
output on the control room speakers. By using
these controls it is possible to build up a monitor
mix of the recorded tracks and any that are about
to be recorded. A fader reverse facility swaps the
Monitor Level control and the Group fader to gain
greater control of the monitor mix. To enhance this
monitor facility, the full complement of all Auxiliary
sends (1 to 8) are available making it possible to
send a headphone mix from the groups together
with reverb and effects and since all Auxiliary
sends are switchable to Pre the monitor level
control, they can be used to create a separate
auxiliary mix independent of the monitor level.
The images on the following pages give a brief
description of the controls on the Group module:

Monitor Section
12-Segment Bargraph Meter
Displays one of 3 sources as determined
by the switches below (MON SOURCE and
AUX TO MTR). The meter is a peak
responding meter with a fast attack and
slower release. It is very useful when used
with complex dynamic waveforms and able
to display sharp transient responses and
greatly assist the engineer when it comes
to avoiding distortion during recording.
MON SOURCE
This switch determines the signal source
to the Group Monitor section; additionally
it displays the signal shown on the
bargraph meter above.
In the UP position the signal fed to the
group Monitor section and bargraph
meter is the Group output. When
depressed (DOWN) the signal fed is
derived from the associated rear MONI-
TOR RETURN TRS jack.
AUX TO MTR
Pressing this switch assigns the
associated Aux Output (post the Aux
Master Level on the master module) to
the bargraph meter above. This allows
the user to check Auxiliary outputs
signal levels from the console on the
meter. Note: When this switch is
pressed the Auxiliary signal sourced to
the bargraph meter overrides any other
signal to the bargraph selected by the
MON SOURCE above. The switch
combinations below explain the various
signal flows:
MON SOURCE (UP) - AUX to MTR (UP) –
Associated Group output feeds monitor

Adjusts the stereo mix level of Effects
Return into the Aux 7 and Aux 8 buses.
AUX 7-8 PAN Control
Adjusts the balance of the stereo Effects
Return signal being fed to Aux 7 bus and
Aux 8 bus.
In the centre (=) position the left stereo
signal is fed to Aux 7 (pre level control) and
the right signal is fed to Aux 8 (pre level
control) and both are attenuated by 3dB.
With the balance control fully anticlockwise
the Left Effects Return signal is fed
unattenuated to Aux 7 (pre level control)
and the right signal is fed fully attenuated to
Aux 8 (pre level control)
With the balance control fully clockwise the

EFX EQ
HIGH Frequency Section – Shelving
Adjusts the high frequency shelving EQ
response. The corner frequency of the
shelving filter is 12 kHz and the Level
control adjusts the cut/boost between
+/- 15dB. The centre “0” position of the
Level control has a detent to indicate
that it is having no effect on the associ-
ated channel signal. Cut or boost of the
high frequency level control is usually
used for minor tonal adjustments.
EQ IN
This switch inserts the 2-band EQ into the
Effects Return signal path. When not in use, it is
suggested that the EQ be kept in the OUT
position for best phase performance.
LOW Frequency Section – Shelving
Adjusts the low frequency shelving EQ
response. The corner frequency of the
shelving filter is 80 Hz and the Level
control adjusts the cut/boost between
+/- 15dB. The centre “0” position of
the Level control has a detent to
indicate that it is having no effect on
the associated channel signal. Cut or
boost of the low frequency level
control is usually used for minor tonal
adjustments.
EFX RTN PAN Control
This control blends the EFX post-
level/post mute signal between the
Left and Right buses. When at the
centre, detented position, both sides
are fed equal amounts of signal
(each down by 3dB).
EFX LEVEL Control
Adjusts the Effects Return signal level
to the Left/Right bus.
EFX RTN SOLO (AFL)
When pressed, routes the stereo Effects
Return (post level and pan) signal to the
Solo bus.
Additionally this switches the Main Monitor
Output (normally fed the Left/Right Mix) to
source the signal from the AFL/PFL Master
Level in the Master section as well as to
trigger LED indicators in the Master section
and Meter-Bridge stating a solo has been
pressed.
EFX RTN MUTE
When pressed will Mute the Effects Return
signal to the Left/Right bus. It is recommended
when the EFX RTN section is not being used
that it be muted.

Monitor EQ
HIGH Frequency Section – Shelving
Adjusts the high frequency shelving
EQ response. The corner frequency of
the shelving filter is 12 kHz and the
Level control adjusts the cut/boost
between +/- 15dB. The centre “0”
position of the Level control has a
detent to indicate that it is having no
effect on the associated channel
signal. Cut or boost of the high
frequency level control is usually used
for minor tonal adjustments.
EQ IN
This switch inserts the 2-band EQ into
the Monitor Input signal path. When not
in use, it is suggested that the EQ be
kept in the OUT position for best phase
performance.
LOW Frequency Section – Shelving
Adjusts the low frequency shelving
EQ response. The corner frequency
of the shelving filter is 80 Hz and
the Level control adjusts the
cut/boost between +/- 15dB. The
centre “0” position of the Level
control has a detent to indicate that
it is having no effect on the associ-
ated channel signal. Cut or boost of
the low frequency level control is
usually used for minor tonal
adjustments.
MONITOR PAN Control
This control blends the Monitor Input
post-level/post mute signal between the
Left and Right buses. When at the centre,
detented position, both sides are fed equal
amounts of signal (each down by 3dB).
MONITOR FADER REVERSE
When depressed, swaps the Monitor Level
Control with the Group Fader Control. The
Monitor signal level to the Left/Right bus is
now controlled by the Group fader, addition-
ally the Group output level is now controlled
by the Monitor Level Control. Note: SOLO and
Mute functions below remain with the
Monitor signal path.
MONITOR SOLO (AFL)
When pressed, routes the Monitor signal (post
level and pan) signal to the Solo bus.
Additionally this switches the Main Monitor
Output (normally fed the Left/Right Mix) to
source the signal from the AFL/PFL Master Level
in the Master section as well as to trigger LED
indicators in the Master section and Meter-
Bridge stating a solo has been pressed.
MONITOR MUTE
When pressed will Mute the Monitor Input
signal to the Left/Right bus. It is recom-
mended when the Monitor section is not
being used that it be muted.

TRIDENT 88 OWNERS MANUAL

The Master section of the 88 console contains all of the controls
that affect the overall functionality of the console. An accurately
matched 100mm stereo fader controls the level of the master
stereo balanced outputs. Housed in the master module is the 8
master auxiliary sends level controls and associated SOLO
switches.
A comprehensive talkback system is provided which incorporates
an internal high quality electret microphone with an option to
switch over to an external microphone, this is plugged into the rear
of the console via a balanced XLR connector (phantom volts avail-
able on XLR). Easy switching to an oscillator source in the talkback
section allows the use of the on board 1kHz or 10kHz sine wave
generator. The signal can be routed to the auxiliary buses in pairs,
the 8 subgroups and to the studio outputs. When the ‘TALK TO
GROUPS’ button is used, the monitor signal is dimmed to avoid
feedback in the control room monitor speakers.
The main monitor system is very comprehensive. The engineer can
monitor anyone of three stereo playback devices. ‘2TK 1 RET’ and
‘2TK 2 RET’ are conventional analogue connections located on the
master connector section so that the playback of a stereo device
such as a cd player or output of a computer sound card can be se-
lected to the control room monitor speakers and a 3.5mm TRS
mini jack available on the module allows the user to plug in his ex-
ternal portable audio source too (e.g. iPod). The monitor system is
provided with a SUM MONO control which combines the left/right
monitor signals so that it is possible to check mono compatibility.
t should be noted that the mono facility is purely a monitor
unction and does not affect the main stereo left/right output which
remains as a true stereo image.
A very useful further facility in this section is the provision of two
alternate monitor outputs (Alt MON TOR 1 and 2) with their indi-
vidual level controls and ON switches. When switched ON routes
the monitor signal to associated set of output jacks on the rear of
the master section so that an alternative monitor system can be
set up. This makes it possible to listen to the signal on (for exam-
ple), a different set of monitor speakers so that comparisons can
be made.
A headphone jack with a high quality stereo amplifier is provided
which allows the engineer to monitor the console only on head-
phones if required. A separate stereo volume control is provided
so that the headphones can be adjusted independently from the
main monitor control level.
A stereo master level control is also provided so that the volume
of the AFL/PFL system can be adjusted into the control room mon-
itor speakers. This comes combined with indicator LED that noti-
fies the user that a console SOLO switch has been pressed and
that the AFL/PFL signal is now being fed to the control room
monitors.
A separate studio playback section is available, with its own level
control and ON switch. The Studio Playback is fed the left right mix.
This can be changed to listen to the mono Aux 1&2 mix, or the
stereo mix of Aux7/8.
The images on the following pages give a brief description of the
controls on the Master module:

Studio Playback
AUX1-2
Assigns the Aux 1 and Aux 2 mixes to the Studio
Playback Left and Right outputs respectively.
Note: When selected replaces the default control
room monitor feed to the Studio Playback
outputs.
PLAYBACK LEVEL CONTROL
This control adjusts the stereo level fed to the
Studio Playback Output TRS jacks. The source
for the Studio Playback is determined by the
state of the Aux1-2 and Aux7-8 switches above.
ON
When depressed, switches the signal to the
Studio Playback outputs on.
AUX7-8
Assigns the Stereo Aux 7 / 8 mix to the Studio
Playback Left and Right outputs.
Note: Priority is given to this over Aux1-2
selection above, and when selected replaces
either the Aux1-2 mix (if selected) or the default
control room monitor feed to the Studio
Playback outputs.
SOLO ACTIVE LED
When this LED is illuminated, it indicates that
one or more SOLO switches have been pressed
on the console. The console monitor output is
now being fed from the solo left/right mix buses.
Additionally the console main Left/Right meters
are switched to monitor the solo left/right mix
and an additional meter bridge indicator flashes
to show the console is in a “SOLO” state.
SOLO MASTER LEVEL CONTROL
This control adjusts the level of the solo
left/right mix fed to the control room monitors
when one or more SOLO switches are selected
on the console. This presets the SOLO signal
level and enables the engineer to balance the
signal levels to the control room monitors from
the main mix and the solo mix. Note: Main Left
Right meters always show the solo signal pre
this level control (unaffected by this control).
ALT MONITOR 1 ON
When this switch is depressed the main
Left/Right Monitor feed is diverted to the ALT
MONITOR 1 output TRS jacks. In doing so, the
console main Left /Right signal is switched OFF.
This allows the engineer to set up a separate
monitor feed (say to another set of monitor
speakers) and be able to A/B the systems for
comparison.
Note: ALT MONITOR 2 ON switch, when
depressed, will override ALT MONITOR 1 ON i.e.
the ALT Montior 1 output will be switched OFF if
ALT MONITOR 2 ON is enabled and signal will be
diverted to ALT Monitor 2 output TRS jacks.
ALT MONITOR 2 ON
When this switch is depressed the main
Left/Right Monitor feed is diverted to the ALT
MONITOR 2 output TRS jacks.
Note: ALT MONITOR 2 ON switch has priority over
ALT MONITOR 1 ON switch.
ALT MONITOR 1 LEVEL CONTROL
This adjusts the level of the console control room
monitor signal is fed to the ALT Monitor 1 output
TRS jacks when ALT MONITOR 1 is turned ON.
ALT MONITOR 2 LEVEL CONTROL
This adjusts the level of the console control room
monitor signal is fed to the ALT Monitor 2 output
TRS jacks when ALT MONITOR 2 is turned ON.

STEREO IN JACK (3.5mm, 1/8”)
This jack allows the engineer to plug
in an external stereo signal via a
standard 1/8” wire cable ( i.e IPOD)
which can then be selected to the
main Control Room Monitors. To
assign this signal into the main
monitors, the user has to depress the
2-TRK 1 switch.
2-TRK 1
When depressed this selects either the signal
from the stereo 2-TRK 1 Return TRS jacks (on the
rear master connector panel) or the stereo signal
plugged in the STEREO IN JACK (above) and feeds
it to the control room monitors. The stereo 2-TRK
1 return signal from the TRS jacks is normalled to
the STEREO IN JACK signal and if a signal wire is
plugged into the STEREO IN JACK it replaces the
signal from the 2-TRK 1 Return TRS jacks and
that is the signal that is switched to the main
monitors. Note: When this switch is depressed,
the main Left/Right mix is disconnected from the
control room monitors, also if 2-TRK 2 switch is
depressed (below) this kills the 2-TRK 1 signal to
the control room monitors. For monitoring signals
into control room monitors the Priority is SOLO
PL[ȹ75.ȹ75.ȹ0DLQ/HIW5LJKW
mix.
2-TRK 2
When depressed this selects the signal from the
stereo 2-TRK 2 Return TRS jacks (on the rear
master connector panel) to the control room
monitors. This switch has priority over 2-TRK 1
switch above. (see description 2 TRK 1 above)
SUM MONO
Combines the Left and Right signals feeding
the control room monitors to produce and
summed (L+R) mono signal that feeds both
Left and Right monitor outputs. Note: The SUM
MONO facility is purely a monitor function and
does NOT affect the main stereo Left/Right
output which remains as a true stereo image.
MONITOR LEVEL CONTROL
This control adjusts the level of the
stereo signal feeding the control
room monitors.
MONITOR MUTE
When depressed this switch kills the
signal being fed to the Control Room
Monitors.
HEADPHONE LEVEL
This control adjusts the level of
signal fed to the headphone jack
below. The signal fed to the
Control Room Monitors also feeds
the headphone jack and this
Headphone level control can be
adjusted independently of the
main MONITOR CONTROL LEVEL.
HEADPHONE JACK (3.5mm, 1/8”)
To monitor the console on headphones the
engineer can plug them into this jack. The
headphones jack is driven by a dedicated high
quality, high current stereo amplifier.
