configuring a system in this manner. The
dynamic range or noise floor of the audio
signals will be impacted and extreme set-
tings could lead to poor monitor system
performance.
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. Spe-
cifically, be aware that the reference level
is reset to minimum level. All the other
parameters 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
Two configuration choices are available on
each Model 71. One is its device address,
the other is the button disable mode. A
small button is located on the back of each
Model 71 Control Console, adjacent to the
9-pin female D-sub connector. Pressing
and holding this button for two seconds
places this specific unit in its configura-

760-03 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. Refer to Figure 9 for details.

address. The rotary level control is used
to select the desired device address; the
LEDs will respond accordingly. The device
address must be selected so as not to con-
flict 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 Figure 10
for details.
Button Disable
To disable the Model 71’s buttons, simulta-
neously press and hold both the dim and
reference buttons for two seconds. When
the disable request has been recognized
the LEDs above both buttons will flash
rapidly. Release the buttons and they will
no longer enable or disable their normal
