Only after the Model 780-01 and all con-
nected Model 790 and Model 71 units
have correctly powered up will full system
operation begin.
Configuration
After the physical installation has been
completed it’s important that the system’s
configuration options be carefully re-
viewed. In most cases one or more of the
operating parameters will be revised to
meet the needs of the specific installa-
tion. Many of the configuration parameters
will impact the signal flow in to and out
of the Model 780-01 Central Controller.
Other parameters affect how the one or
more Model 790 Control Consoles will
display status conditions and respond to
user commands. Most of the configuration
choices will be made using a Model 790
Control Console. However, two configura-
tion choices are available for any connect-
ed Model 71 Control Consoles.
Configurable Parameters
Many StudioComm functions can be
configured to meet the exact needs of an
installation. A Model 790 Control Console
is used to display and select the desired
system configuration. Here’s an overview
of what can be configured:
• Model 790 Device Address (must be
unique for each unit!)
• Stereo Input Sample Rate Converter
• Bass Management
• Sync Source
• Sync Input Termination
• Audio-Synced-to-Video Sample Rate
• Reference Level
• Overall Display Mode
• Reference Level in dB SPL
• Auto Reference Level Off
• Dim Level
• Remote Inputs
• LFE Downmix Level
• Pre-Fader Monitor Output Mode
• Input Delay Settings
• Post-Fader Monitor Output Channel
Level Offsets
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 790 Control Console, adjacent
to its 9-pin female D-subminiature con-
nector. On any connected Model 790 unit
pressing and holding its configure button
for two seconds places both this specific
unit and the Model 780-01 into their con-
figuration modes. Other connected Model
790 and Model 71 units will enter a stand-
by mode. When the Model 780-01 enters
its configuration mode it will immediately
mute the pre- and post-fader monitor out-
puts, providing an equipment and speaker
protection measure. When a specific Mod-
el 790 has entered the configuration mode
its array of buttons and LEDs will no longer
perform their normal functions, instead
being used to display the configuration
settings and reflect changes as they are
being made.
