for Surround
intended to represent the sound pressure
level in dB SPL, a figure that should directly
relate to the actual sound pressure level
that the surround or stereo loudspeaker
system is presenting to users. (Typically,
the level value would actually be in dBC,
the C-weighted sound pressure level.)
When the reference level button is enabled,
or the rotary level control is set so that
the reference level has been reached, the
display will typically show something in the
range of 82 to 87 dB. Assuming that the
monitoring environment has been correctly
calibrated, this would indicate that an aver-
age listening level of 85 dB, for example,
had been achieved.
Channel Pop Solo Display
As has been previously discussed, the
channel pop solo mode offers a unique way
of sonically highlighting an individual chan-
nel. A channel selected for soloing in this
mode will have its level increased while the
other non-soloed channels will be reduced
in level. To highlight this condition the let-
ters POP will appear in the 4-digit display
whenever a channel is actively being soloed
in the channel pop solo mode. This ensures
that a user will understand that the monitor
outputs no longer represent the true inter-
channel level relationships.
Remote Control Inputs
As previously discussed in the Installa-
tion section of this user guide, two remote
control signals can be connected to the
Model 76D and then configured for opera-
tion. The functions are remote mute all and
remote dim. When an external signal acti-
vates remote mute all the LED on the Model
77 associated with the mute all button will
flash. If mute all was already active when
the remote mute all function is activated,
the LED will change from being steadily lit
to flashing.
When an external signal activates remote
dim the LED on the Model 77 associated
with the dim button will flash. If dim was
already active when remote dim is activated,
the LED will change from being steadily lit
to flashing.
Model 71 Control Console
The Model 71 Control Console provides a
rotary level control and a limited number of
pushbutton switches and LEDs for control
and status display. The rotary level control
allows adjustment of the post-fader surround
and stereo monitor output levels. Two but-
tons, along with associated LEDs, provide
access to the dim and reference level func-
tions. A status LED lights steadily whenever
normal Model 71 operation is taking place.
Any changes made using the Model 71’s
rotary level control and buttons will be re-
flected in the appropriate LEDs and displays
on all the connected Model 77 and Model 71
units. And, as expected, changes made us-
ing a Model 77 will be reflected in the Model
71’s LEDs.
In some applications it may be desirable to
disable operation of a Model 71’s dim and
reference buttons. An example could be
where non-technical personnel are allowed
only to use the rotary level control. A con-
figuration parameter, previously described
in the Model 71 Control Console Configura-
tion section, allows button operation to be
disabled.
Rotary Level Control
The rotary level control is used to manually
adjust the post-fader surround and stereo
monitor output levels. Its operating charac-
teristics are identical to those of the Model
