stored reference level. Refer to Figure 7.
This feature can be useful in broadcast
transmission and distribution applications.
In theory, any time the dot in the lower-
right corner is not lit the current dialnorm
level value is causing a level adjustment to
take place. This level adjustment may be
taking place in the StudioComm system, if
the dialnorm enable function is active, as
well as in downstream users of the broad-
cast signal.
Note that if a valid dialnorm source is not
available the 4-digit display, when selected
to display dialnorm, will show four horizon-
tal bars. This could be due to a problem
with the metadata signal connected to the
Model 76B Central Controller. But more
frequently this will simply be the normal
result that occurs when the Model 77B’s
input is not selected for the metadata-
associated surround input source.
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 condi-
tion 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understand that the monitor outputs no
longer represent the true inter-channel
level relationships.
Remote Control Inputs
Three remote control signals can be con-
nected to the StudioComm system and
confi gured for operation. The functions are
remote mute all, remote dim, and remote
auxiliary output on/off. When an external
signal activates remote mute all the LEDs
on the Model 77B associated with the
mute all button will fl ash. If mute all was
already active when the remote mute all
function is activated, the LED will change
from being steadily lit to fl ashing.
When an external signal activates remote
dim the LED on the Model 77B associated
with the dim button will fl ash. If dim was al-
ready active when remote dim is activated,
the LED will change from being steadily lit
to fl ashing.
When an external signal activates remote
auxiliary output the LED associated with
the auxiliary output enable button will fl ash.
If the auxiliary output was already active
when remote auxiliary output on/off is
activated, the LED will change from being
steadily lit to fl ashing.
Technical Notes
Dialnorm
A source of Dolby E metadata can be
connected to the Model 76B Central Con-
troller. Within this fl ow of metadata frames
can be a “dialnorm” level value that’s as-
sociated with one of the Model 76B’s 5.1
