of LEDs displays the headphone source
mode. When the LED is off the headphone
source is selected independently of the
control room source. When the LED is
lit the headphone source follows the
control room source. To make a change
you hold Level Up, hold the Phones/Stu-
dio button and press the input 1 button. If
you can make this change using only one

Level Control Auto Mute
The level control auto mute function
automatically mutes the monitor output
channels whenever the rotary level con-
trol knob is in its fully counterclockwise
position. In some applications it may be
desirable to enable this function. When
disabled, the rotary level control adjusts
the monitor output level over an approxi-
mately 72dB range; no automatic muting
takes place.
Dub Source Selection
The default configuration makes the selec-
tion of the dub source independent of the
control room or headphone selections.
While this most flexible there are opera-
tional scenarios where it would be conve-
nient for the dub source to follow whatever
is selected for the control room source.
While holding Level Up, the second LED
associated with the Phones/Studio col-
umn of LEDs displays the dub source
mode. When the LED is off the dub source
is selected independently of the control
room source. When the LED is lit the dub
source follows the control room source. To
make a change you hold Level Up, hold
the Phones/Studio button and press the
CR/Studio button 2.
Remote Control Room Source Select
The Remote Control Room Source Select
function allows a contact closure to auto-
matically select input 6 or 7 as the control
room source. The remote control input
connection that is, by default, associated
with the remote talk to studio function is
used to activate Remote Control Room
Source Select.
While holding Level Up, the third and four
LEDs associated with the Phones/Studio
column of LEDs display the status of the
Remote Control Room Source Select func-
tion. When the third LED is off the function
is not active. When the third LED is on the
function is active. The fourth LED displays
the input channel associated with the
function. When the LED is off channel 6
is selected. When the LED is on channel 7
is selected.
Operation
Now that you’ve installed and config-
ured the system, you’re ready to go. You
should find operation very easy.
Model 50 Central Controller
The Model 50 front panel contains seven
LEDs, one stereo line input, and one ste-
reo line output.
The power present LED should be lit
whenever AC mains power is connected.
During normal operation the two Over
Current LEDs will not be lit. They will flash
only if there is a problem interfacing with
the Model 51 Control Console or the talent
amplifiers that you have connected. Refer
to Troubleshooting section if either Over
Current LED lights.
