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 dial-
norm enable function is active, as well as in
downstream users of the broadcast signal.
Note that if a valid dialnorm source is not
available the 4-digit display, when selected
to display dialnorm, will show four horizontal
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 chan-
nel 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 chan-
nel 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no longer represent the true inter-channel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
configured for operation. The functions are
remote mute all, remote dim, and remote
auxiliary monitor output on/off. When an
external signal activates remote mute all
the LEDs on the Model 77B 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 77B 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.
When an external signal activates remote
auxiliary monitor output the LED associat-
ed with the auxiliary monitor output enable
button will flash. If the auxiliary monitor
output was already active when remote
auxiliary monitor output on/off is activated,
the LED will change from being steadily lit
to flashing.
Technical Notes
Dialnorm
A source of Dolby E metadata can be
connected to the Model 76B Central Con-
troller. Within this flow of metadata frames
can be a “dialnorm” level value that’s as-
sociated with one of the Model 76B’s 5.1
surround input signals. When this surround
input is selected for monitoring its associ-
ated dialnorm level value can be displayed
