Operation
Now that you’ve installed and configured
the system, you’re ready to go. You should
find operation very easy. However, taking
time to study this section of the guide may
prove valuable.
Upon power up the system will return to
the last operating condition, including the
selected source, downmix modes, etc. As
a precaution, however, the post-fader sur-
round and stereo monitor output levels will
always return to their minimum value. The
rotary level control or the reference level
button must then be used to return the sys-
tem to the desired monitor output level.
Model 76D Central Controller
The Model 76D’s front panel contains two
LEDs. The control console status LED will
light whenever the Model 76D is commu-
nicating with the one or more connected
Model 77 or Model 71 units. A flashing
control console status LED will indicate
that the DC power output supporting the
control consoles is in a short circuit or
over-current condition. The control console
status LED will not light when a Model 77
is in the configuration mode or when the
Model 77 is going through its power-up
sequence.
The sync status LED will light whenever
a valid timing reference signal is being
received by the Model 76D. A flashing
sync status LED indicates that a valid
sync signal is not being received.
Control Consoles
StudioComm for Surround operation is
controlled using the up to four Model 77
or Model 71 Control Consoles that have
been connected. Two system functions
can also be controlled by means of the
remote control inputs.
Model 77 Control Console
To make things easy to describe, the
Model 77’s operator functions are divided
into six main groups: input source selec-
tion, downmix, monitor output general
functions, channel mute/solo, display and
display mode, and remote control inputs.
Any change made to any one Model 77
unit will be reflected in the LEDs and dis-
plays on all the connected units. Note that
all control consoles function simultane-
ously—there is no priority of one unit over
the others.
Input Source Selection
To select an input source press one of the
five input source buttons. The correspond-
ing LED will light to indicate that the input
has been selected. Typically, only one
source will be selected for monitoring at
any one time. However, input stereo C can
be selected by itself, or mixed (summed)
with one of the other four inputs. To accom-
plish this is easy: simply press and hold
input stereo C then press the button asso-
ciated with the other desired input source.
The two corresponding LEDs will light.
Alternately, press and hold the first desired
input (other than input stereo C) and then
press the input stereo C button.
It’s possible (although unlikely) that
selecting an input will result in the mute
all function being enabled and an Err3
message being displayed. This would
indicate a conflict between the sample rate
of the selected input source and the bass
management function. (Operation of the
bass management function requires the
source to have a sample rate of 44.1, 48,
