Operation
Now that you’ve installed and confi gured
the system, you’re ready to go. You should
fi nd operation very easy.
Model 74 Central Controller
The Model 74’s front panel contains
two LEDs. The power LED should be lit
whenever AC mains power is connected.
The data LED will light whenever a MIDI
system-exclusive message is received
from the Model 75.
Model 75 Control Console
StudioComm operation is controlled using
the Model 75 Control Console and, if con-
nected, the remote control inputs. To make
things easy to describe, we’ve divided
the StudioComm functions into six main
groups: input source selection, downmix,
monitor output functions, mute/solo, head-
phone cue system/talkback, and remote
controls.
Input Source Selection
Input source selection is simple. To select
an input source for routing to the moni-
tor outputs, press one of the four input
source buttons. The corresponding LED
will light to let you know that the input has
been selected. You can select more than
one input source simultaneously; up to all
four. The selected inputs will be summed
(combined). Start by pressing and holding
the button associated with the fi rst de-
sired input source. While the button is still
pressed, add the extra inputs by momen-
tarily pressing the buttons associated with
them. The LEDs will light to tell you which
inputs have been selected.
A recall feature is an integral part of the
input selection process. It’s a bit confusing
to explain, but simple once you experience
it in “real time.” A one-sentence explana-
tion would describe the input recall feature
as allowing the system to return to the
previously selected input (or inputs) by
simply pressing one button. It was included
specifi cally for fi lm-post applications where
it’s important to be able to change quickly
between a combination of inputs, such as
two “stems,” and a single input.
Let’s begin the explanation with an ex-
ample: A fi lm-post facility where the usual
monitoring setup has both Surround A
and Surround B simultaneously selected,
while Stereo A is occasionally selected to
monitor a cue track. To select both inputs,
press and hold the button associated with
Surround A, then press Surround B’s but-
ton, then release both buttons. Surround
A and B are now selected for monitoring.
To monitor Stereo A press the button as-
sociated with it. To return to monitoring
Surround A and B, simply press Stereo A’s
button again. The recall feature has re-
turned the system to the previously
selected inputs. That’s all there is to it!
A special confi guration mode allows an in-
put to be disabled. This would be appropri-
ate if an input is not connected to an audio
source. If you press an input source button
and the previously selected input source
does not change, the newly selected input
has been disabled.
Downmix
Two downmix functions allow an opera-
tor to perform “real-world” compatibility
checks. They can also be referred to as
format functions because they allow con-
version between various audio formats,
e.g., 5.1 (surround) signals converted
