in this section, give details on setting each
parameter. An overview of each configu-
rable parameter is provided in the following
paragraphs.
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 D-sub connector. On any con-
nected Model 77 pressing and holding this
button for two seconds places both this
specific unit and the Model 76DA into their
configuration modes. Other connected
Model 77 and Model 71 units will enter
a standby mode. When the Model 76DA
enters its configuration mode it will imme-
diately mute the digital and analog monitor
outputs as a speaker protection measure.
When a Model 77 enters the configura-
tion mode its array of buttons and LEDs
no longer perform their normal functions,
instead they are used to display the oper-
ating parameters and reflect configuration
changes as they are made.
As a user aid, a Model 77 that has entered
the configuration mode will have its mute
and solo LEDs (associated with the chan-
nel mute/solo section) light in an alternat-
ing manner. Other connected Model 77
units will indicate that they have entered
the standby mode by simultaneously flash-
ing their mute and solo LEDs.
To leave the configuration mode and return
the system to normal operation requires
one last action to be made on the Model
77 unit that’s in its configuration mode;
press and hold its configure the button
for two seconds. Note that configuration
changes are stored in nonvolatile memory
only after the configuration mode has been
exited.
Our apologies to those of you who find
the configure button a pain to use, but it’s
supposed to be that way! Seriously, the top
of the button is slightly recessed from the
back panel, making it harder to acciden-
tally activate. We didn’t want normal opera-
tion to cease because someone pushed
a Model 77 into a “rats nest” of schedules,
memos from management, and empty cof-
fee cups! But a firm press with the fleshy
part of an index finger should do the trick.
