Operation
Now that you’ve installed and confi gured
the system, you’re ready to go. You should
fi nd 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
fi ve 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 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 your fi rst 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 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 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 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.
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,
e.g., surround signals converted to stereo;
