using the dim and reference level LEDs,
as shown in Figure 8 in the Configuration
section. When this is complete the Model 71
will begin normal operation and its status
LED will light if communication is estab-
lished with the Model 76DA. If the Model
71’s status LED does not light check to see
if there is a device address conflict among
all connected control consoles and that all
cables are connected properly.
Should an error be detected during the
start-up process the two LEDs on the Model
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 opera-
tion 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
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 config-
ured to meet the exact needs of an installa-
tion. A Model 77 Control Console is used to
display and select the desired system con-
figuration. Here’s an overview of what can
be configured:
• Model 77 Device Address (must be
unique for each unit!)
