Should an error be detected during the
start-up process the two LEDs on the Mod-
el 76DA’s front panel will continue to flash
in cadence indefinitely. On the Model 77
units a diagnostic code may be displayed.
Refer to the Technical Notes section of this
user guide for details.
Only after the Model 76DA and all con-
nected Model 77 and Model 71 units have
correctly powered up will full system oper-
ation begin. It’s possible that audio signals
will first be present on the digital monitor
outputs. The analog monitor outputs will
only become active after a protection inter-
val has elapsed. These outputs are muted
using electro-mechanical relays that oper-
ate under software control.
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
76DA Central Controller. Other parameters
affect how the one or more Model 77 Con-
trol Consoles will display status conditions
and respond to user commands. Most of
the configuration choices will be made us-
ing a Model 77 Control Console. However,
one configuration choice is available for
each of the connected Model 71 Control
Consoles.
Configurable Parameters
Many StudioComm functions can be con-
figured to meet the exact needs of an
installation. A Model 77 Control Console
is used to display and select the desired
system configuration. Here’s an overview
of what can be configured:
• Model 77 Device Address (must be
unique for each unit!)
• Stereo Input C Sample Rate Converter
