for Surround
Display in dB of Attenuation
If configured for the attenuation mode
the display will show the post-fader moni-
tor output level as an attenuation value in
reference to the maximum output. This is
in the form of 0.5-dB steps less than the
maximum of 0.0 dB. So a display of –40.5
would indicate that the surround or stereo
monitor output is set to be 40.5 dB below
the maximum level. As the rotary level con-
trol is moved counterclockwise the output
level will go down and the indicated value
will get more negative.
Display in dB SPL
If the Model 77 is configured to display
the post-fader digital and analog monitor
output level in dB SPL, the 4-digit display
will always show the output level in positive
numbers. These numbers are 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 refer-
ence level has been reached, the display
will typically show something in the range
of 82 to 87 dB. Assuming that the monitor-
ing environment has been correctly cali-
brated, this would indicate that an average
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
channel. 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 letters 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 under-
stand that the post-fader monitor outputs
no longer represent the true inter-channel
level relationships.
Remote Control Inputs
As previously discussed in the Installation
section of this user guide, two remote
control signals can be connected to the
Model 76DA and then configured for op-
eration. The functions are remote mute
all and remote dim. When an external
signal activates 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 acti-
vated, the LED will change from being
steadily lit to flashing.
Model 71 Control Console
The Model 71 Control Console provides
a limited number of pushbutton switches,
LEDs, and a rotary level control for status
display and control. The two buttons, along
with associated LEDs, provide access to
the dim and reference level functions. A
rotary level control allows adjustment of
the post-fader surround and stereo monitor
output levels. A status LED lights steadily
whenever normal Model 71 operation is
taking place.
