Restore Factory Defaults
The restore factory defaults function is pro-
vided primarily for factory use. In this way
a system can be shipped with the default
settings selected. While you are welcome
to use this function, be careful so that your
configuration efforts aren’t wasted. Specifi-
cally, be aware that the reference level is
reset to minimum level. All the other param-
eters are fairly easy to set up, but resetting
the reference level would require getting
out an SPL meter and a calibrated signal
source. This is a hassle you may not need!
Model 71 Control Console
Configuration
The only configuration choice available on
a Model 71 is its device address. It must be
selected so as not to conflict with the device
address of any other connected Model 71
or Model 77 Control Console. The choices
are A1, A2, A3, and A4. All Model 71 units
have a default device address of A4; Model
77’s units have a default device address
of A1. This ensures that, in most cases,
no change will have to be made. Refer to
Figures 8 and 9 for details.

each Model 71 Control Console, adjacent
to the 9-pin D-sub connector. Pressing and
holding this button for two seconds places
this specific unit in its configuration mode;
normal operation of the Model 76DA and
other connected Model 71 and Model 77
units will continue. When a Model 71 enters
its configuration mode its three LEDs will no
longer perform their usual functions. Instead
the status LED will blink to indicate that
configuration mode is active. The dim and

reference level LEDs will display the Model
71’s current device address. The rotary level
control is used to select the desired device
address; the LEDs will respond accordingly.
To leave the configuration mode and return
a Model 71 to normal operation requires
one last action; again press and hold its
configure button for two seconds. The
selected device address will be stored in a
nonvolatile memory device that is located
inside this specific Model 71.
