The Model 69A configuration diagrams,
located at the end of this section, give
details on how each parameter is set. An
overview of each configurable parameter
is provided in the following paragraphs.
Entering and Exiting the Configuration
Mode
A small button is located on the back of
the Model 69A Control Console, adjacent
to the 9-pin D-sub connector. Pressing
and holding this button for two seconds
places the Model 69A into the configura-
tion mode. In the configuration mode the
Model 69A’s array of buttons and LEDs
no longer perform their normal functions,
but instead allow you to observe and
change many of the operating parameters.
The mute/solo mode LEDs light alternately
to indicate that the configuration mode is
active.
