The Master Module
The Master section of the TRIDENT 78 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. A key feature is the addition of a
switchable transformer into the left/right monitor outs, which when
fitted allows the user to put two high quality transformers into the
monitor output path. These transformers are an optional add on and
do not come standard.
A talkback system is provided which incorporates an internal high
quality electret microphone with an option to switch over to an ex-
ternal microphone, this is plugged into the rear of the console via the
associated DSUB connector pins, +48V phantom volts are always avail-
able on these pins. The talkback signal can be routed to the auxiliary
buses and the 8 subgroups. 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 selected to the con-
trol room monitor speakers and a 3.5mm TRS mini jack available on the
module allows the user to plug in his external 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. It should be noted that the mono facility
is purely a monitor function 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 an alternate
monitor outputs (Alt MONITOR) which when switched ON routes the
monitor signal to associated set of output pins on the rear of the mas-
ter section so that an alternative monitor system can be set up. This
makes it possible to listen to the signal on (for example), 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 headphones
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 monitor speak-
ers. This comes combined with indicator LED that notifies 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.
The following gives a brief description of the controls on the Master module.
