for Surround
Display in dB SPL
If the Model 77 is configured to display
the 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 fig-
ure 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 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 understand
that the digital and analog 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no longer represent the true inter-channel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
operation. 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 al-
ready 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 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 digital
and analog monitor output levels. A sta-
tus 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
reflected in the appropriate LEDs and dis-
plays on all the connected Model 77 and
Model 71 units. And, as expected, changes
made using a Model 77 will be reflected in
the Model 71’s LEDs.
Rotary Level Control
The rotary level control is used to manually
adjust the post-fader surround and stereo
digital and analog monitor output levels.
Its operating characteristics are identical
to those of the Model 77 Control Console,
discussed earlier in this section.
