Studio Technologies, Inc.
When used with the Model 51 Control Con-
sole, both Input Data LEDs will light when-
ever a message is received. Why are there
two LEDs? They are provided for diagnostic
use in those special cases where the Model
51 is not used, and another source is pro-
viding the messages. The Bus LED lights
whenever any data is received, whether the
messages are intended for the Model 50 or
not. The Model 50 Input Data LED will light
only when a MIDI-exclusive message that
matches the Model 50’s format is received.
Refer to the Troubleshooting section if nei-
ther LED flashes during operation with the
Model 51 Control Console.
Input 7 is located on the front panel for easy
access; connecting a temporary source to
your system doesn’t require getting at the
back of the Model 50. The LED associated
with input 7 will light whenever the input
is configured for +4dBu operation. If you
require a change in input level refer to the
Configuration section for details.
Again as a convenience function, dub out-
put is available on the front panel. The LED
associated with the dub output is lit when-
ever the output is set for +4dBu operation.
Refer to the Configuration section if you
require a change in dub configuration.
Model 51 Control Console
All StudioComm functions are controlled
using the Model 51 Control Console. To
make things easy, we’ve divided the
StudioComm functions into four main
groups: input-output selection, control
room outputs, studio output, and communi-
cations functions.
Input-Output Selection
Input-output selection is simple. To select
an input for monitoring in the control room,
press one of the seven CR/Studio buttons.
The corresponding LED in the CR/Studio
column will light to let you know which in-
put is selected. If the input is set for mono
the LED will continually flash on and off as
a warning.
If the remote control room source select
function is enabled, the select button
associated with either input 6 or input 7
will not be usable. A remote signal will
cause this input to be selected. Whenever
the remote signal is activated, the control
room source will automatically change to
the designated input (6 or 7). When the
remote signal is no longer active, the con-
trol room input source will return to
the previous selection.
The source selected for control room
monitoring will automatically be connect-
ed to the meter output. There is no inde-
pendent selection of the meter output.
If the studio source is configured to follow
the control room source, it will automati-
cally switch to the input you select. You
can easily tell if the studio is following
the control room because whenever the
studio output is on, the studio On LED will
flash each time you select a new input.
Selection of the headphone source de-
pends on how the Model 51 has been
configured. In the default operating mode,
to select an input for the headphones,
press and hold the Phones/Studio button
and press one of the seven CR/Studio
buttons. In the Phones/Studio column,
the LED for the input you select will light.
If the input is set for mono the LED will
continually flash on and off as a warning.
If the studio source is configured to follow
the headphone source, the studio source
will automatically switch to the same input,
and, whenever the studio output is on, the
studio On LED will flash once.
