for Surround
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 out-
put 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 sur-
round or stereo loudspeaker system is pre-
senting 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 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 post-fad-
er monitor outputs no longer represent the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 760-03 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
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 sur-
round and stereo monitor output levels.
Two buttons, along with associated LEDs,
provide access to the dim and reference
level functions. 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
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.
In some applications it may be desirable to
disable operation of a Model 71’s dim and
