Configuration
After the physical installation has been
completed it’s important that the system’s
configuration options be carefully reviewed.
In most cases one or more of the operating
parameters will need to be revised to meet
the needs of the specific installation. Many
of the configuration parameters will impact
the signal flow in to and out of the Model
76DBA Central Controller. Other param-
eters affect how the one or more Model
77B Control Consoles will display status
conditions and respond to user commands.
Most of the configuration choices will be
made using a Model 77B Control Console.
However, one configuration choice is avail-
able for each of the connected Model 71
Control Consoles.
Configurable Parameters
Many StudioComm functions can be
configured to meet the exact needs of an
installation. A Model 77B Control Console
is used to display and select the desired
system configuration. Here’s an overview
of what can be configured:
• Model 77B Device Address (unique for
each unit)
• Stereo Input C Sample Rate Converter
• Auxiliary Monitor Output Nominal Level
• Sync Source
• Sync Input Termination
• Audio-Synced-to-Video Sample Rate
• Digital Monitor Output Types
• Input Select Buttons
• Reference Level
• Overall Display Mode
• Reference Level in dB SPL
• Auto Reference Level Off
• Dialnorm Reference Level
• Dialnorm-Data-to-Surround-Input
Assignment
• Dim Level
• Remote Inputs
• Input Delay
• LFE Downmix Mode
• Pre-Fader Surround Digital Monitor
Output Mode
• Channel Pop Solo Mode Offset Levels
The configuration diagrams, located later
in this section, give details on setting each
parameter. An overview of each configu-
rable parameter is provided in the following
paragraphs.
Entering and Exiting the
Configuration Mode
A small button is located on the back of
each Model 77B Control Console, adjacent
to its 9-pin D-sub connector. On any con-
nected Model 77B pressing and holding
this button for two seconds places both
this specific unit and the Model 76DBA
into their configuration modes. Other con-
nected Model 77B and Model 71 units will
enter a standby mode. When the Model
76DBA enters its configuration mode it will
immediately mute the digital and analog
monitor outputs as a speaker protection
measure. When a Model 77B enters the
configuration mode its array of buttons and
LEDs no longer perform their normal func-
tions, instead they are used to display the
operating parameters and reflect configu-
ration changes as they are made.
As a user aid, a Model 77B that has en-
tered the configuration mode will have its
