Operation
Now that you’ve installed and configured
the system, you’re ready to go. You should
find operation very easy.
Model 68A Central Controller
The Model 68A’s front panel contains two
LEDs. The power LED should be lit when-
ever AC mains power is connected. The
data LED will light whenever a MIDI
system-exclusive message is received
from the Model 69A.
Model 69A Control Console
StudioComm operation is controlled using
the Model 69A Control Console and, if
connected, the remote control inputs.
To make things easy to describe, we’ve
divided the StudioComm functions into
five main groups: input source selection,
format, monitor output general functions,
mute/solo, and remote controls.
Input Source Selection
Input source selection is simple. To select
an input source for routing to the monitor
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 (com-
bined). Start by pressing and holding the
button associated with your first input
source. While the button is still pressed,
add the extra inputs by momentarily press-
ing 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 in-
cluded specifically for film-post applica-
tions 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 film-post facility where the usual
monitoring setup has both Surround A and
Surround B simultaneously selected, while
Stereo A is occasionally selected to moni-
tor a cue track. To select both inputs,
press and hold the button associated with
Surround A, then press Surround B’s
button, then release both buttons. Sur-
round A and Surround B are now selected
for monitoring. To monitor Stereo A press
the button associated with it. To return to
monitoring Surround A and Surround B,
simply press Stereo A’s button again. The
recall feature has returned the system to
the previously selected inputs. That’s all
there is to it!
A special configuration mode allows an
input to be disabled. This would be appro-
priate 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 se-
lected input has been disabled.
Format
The downmix and mono functions allow
an operator to perform “real world” com-
patibility checks. They are referred to as
format functions because they allow con-
version between various audio formats,
