 The Master Module MONITOR SECTION

Trident 78

 Master TALKBACK  SECTION

MONITOR LEVEL 

CONTROL

This control adjusts the level of the 

stereo signal feeding 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 Moni-
tors also feeds the headphone jack 
and this Headphone level control can 
be adjusted independently of the main 
MONITOR CONTROL LEVEL.

MONITOR MUTE

When depressed this switch kills the 
signal being fed to the Control Room 
Monitors.

DIM

When depressed, this reduces the 
level of the main monitor outputs by 
approx 30 dB. 

Note: 

this has no ef-

fect on the main Left/Right outputs 
of the console.

ALT MONITOR 1 ON

When this switch is depressed the 
main Left/Right Monitor feed is di-
verted to the ALT MONITOR output 
pins of the associated DSUB on the 
rear connector panel.. In doing so, 
the console main Left /Right signal 
is switched OFF. This allows the en-
gineer to set up a separate monitor 
feed (say to another set of monitor 
speakers) and be able to A/B the sys-
tems for comparison.

TALKBACK MIC

Directly behind this location is situat-
ed the internal high quality electrets 
microphone.

TALK TO GROUPS

Momentary switch, which when de-
pressed assigns the talkback signal 
(post the talkback LEVEL Control) 
to the all the group buses. Addition-
ally when depressed the signal to the 
control room monitor is dimmed (at-
tenuated) by approx 30 dB to avoid a 
feedback situation in the control room 
monitor speakers.

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.

TALKBACK LEVEL 

CONTROL

This control adjusts the level of the 

talkback microphone to the talkback 

destinations below.

EXTERNAL MIC

When depressed switches the talk-
back microphone source from the 
internal electrets above or the exter-
nal microphone plugged into the ap-
propriated pins of the DSUB situated 
on the rear master connector panel. 
Note: the rear panel talkback micro-
phone connector is supplied with 
+48V phantom voltage and feeds into 
an internal high quality preamp stage.

TALK TO AUXES

Momentary switch, which when de-
pressed assigns the talkback signal 
(post the talkback LEVEL Control) to 
all AUX mix busses.
