Confi guration
After the physical installation has been
completed it’s important that the system’s
confi guration options be carefully reviewed.
In most cases one or more of the operating
parameters will need to be revised to meet
the needs of a specifi c installation. Many
of the parameters will impact the signal
fl ow in to and out of the Model 761 Central
Controller. Other parameters affect how
the Model 771 Console will display status
conditions and respond to user commands.
Confi gurable Parameters
Many StudioComm functions can be con-
fi gured to meet the exact needs of an in-
stallation. The Model 771 Control Console
is used to display and select the desired
system confi guration. Here’s an overview
of what can be confi gured:
• Digital Input Sample Rate
• Digital Input Reference Level
• Monitor Output Nominal Level
• SD Primary Input Type
• Director Cue Output Nominal Level
• Reference Level
• Overall Display Mode
• SPL Reference Level
• Dialnorm Reference Level
• Dim Level
• Remote Inputs
The confi guration diagrams, located at
the end of this section, give details on set-
ting each parameter. An overview of each
confi gurable parameter is provided in the
following paragraphs.
Entering and Exiting the Confi guration
Mode
A small button is located on the back of
the Model 771 Control Console, adjacent
to the 9-pin D-sub connector. Pressing and
holding this button for two seconds places
both the Model 761 and the Model 771
into the confi guration mode. The Model
761 will immediately mute the analog out-
puts as a protection measure. In the con-
fi guration mode the Model 771’s array of
buttons and LEDs no longer perform their
normal functions, instead they allow you to
observe and change many of the operating
parameters. The dialnorm and output level
LEDs, associated with the display mode
section, will light alternately to indicate that
the confi guration mode is active.
To leave the confi guration mode and return
the Model 771 to normal operation once
again press and hold the confi gure button
for two seconds. Note that confi guration
changes are stored in nonvolatile memory
only after the confi guration mode has been
exited.
Our apologies to those of you who fi nd
the confi gure button a pain to use, but it’s
supposed to be that way! Seriously, the top
of the button is slightly recessed from the
back panel, making it harder to acciden-
tally activate. We didn’t want normal opera-
tion to cease because someone pushed
the Model 771 into a “rats nest” of sched-
ules, magazines, or burrito wrappers! But
a fi rm press with the fl eshy part of an index
fi nger should do the trick.
There is no problem frequently “tweak-
ing” the Model 771’s operating parameters
to achieve the desired performance. The
confi guration data is stored in nonvola-
tile memory, which is rated for thousands
of read and write cycles and a retention
