Only after the Model 760-03 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
760-03 Central Controller. Other param-
eters affect how the one or more Model
77 Control Consoles will display status
conditions and respond to user commands.
Most of the configuration choices will be
made using a Model 77 Control Console.
However, two configuration choices are
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

• Model 77 Device Address (must be
unique for each unit!)

Entering and Exiting the
Configuration Mode
A small button is located on the back of
each Model 77 Control Console, adjacent
to its 9-pin female D-sub connector. On
any connected Model 77 pressing and
holding this button for two seconds places
both this specific unit and the Model 760-03
into their configuration modes. Other con-
nected Model 77 and Model 71 units will
