control is set to minimum, return AC

amplified speakers.
Model 79 Operating
Parameters
Many StudioComm functions can be
configured to meet the exact needs of your
installation. Here’s an overview of what you
can configure:
• Input channels active
• Solo mode
• Power-up mute all
• Level control response
• Level control auto mute all
• Output level offset
• Output level range
• Reference level
• Dim level
• Downmix modes
• Remote control inputs
The Model 79 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 79 Control Console, adjacent to the
9-pin D-sub connector. Pressing and hold-
ing this button for two seconds places the
Model 79 into the configuration mode. In
the configuration mode the Model 79’s ar-
ray 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.
To leave the configuration mode and return
the Model 79 to normal operation, once
again press and hold the configure button
for two seconds. Note that configuration
changes are stored only after the configu-
ration 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
the Model 79 into a “rats nest” of music
scores or track sheets!
There is no problem frequently “tweak-
ing” the Model 79’s operating parameters
to achieve the desired performance. The
configuration data is stored in nonvolatile
memory, which is rated for thousands of
read and write cycles and a retention time
in tens of years.
Input Channels Active
The configuration parameter for the num-
ber of channels active for each input is pro-
vided for those cases where a source has
less than eight channels. Let’s look at an
example. Surround A is connected to an
8-channel source, so its default configura-
tion is fine. But the source for Surround B
is different, having only six channels: left,
right, center, LFE, surround left, and sur-
round right. This makes it not so “cool”
for the operator to select Surround B for
monitoring, as the unconnected back
left and back right input channels will get
