The Configure button allows the Model 56
to go into the configure mode. While in the
configure mode, all the Model 56’s buttons
and LEDs are associated with configure
functions. Refer to the Model 56 Configu-
ration Chart later in this section.
To enter the configure mode, press and
hold the Configure button for two seconds.
While in the configure mode, all audio
outputs switch off and the orange LED
beside the Configure button will flash. As
you make changes, the Model 56 keeps
track of the new settings and updates the
system when you exit the configure mode.
You must exit the configure mode before
any changes take effect.
Input Sensitivity
The CR column of four red LEDs shows
you whether an input is set to be compat-
ible with –10dBV or +4dBu signal levels.
When a red LED in the CR column is off,
it means the input is set to –10dBV. When
lit, the corresponding input is set to +4dBu.
Just press the CR buttons to toggle inputs
1 through 4 between –10dBV and +4dBu.
Stereo/Mono Input
The Phones column of green LEDs indi-
cates whether an input is configured for
mono or stereo operation. When a green
LED in this column is off, the input is set
for stereo; the LED on means the corre-
sponding input is set for mono. In mono
mode, the left input is sent out both the
left and right outputs. To toggle a channel
between stereo and mono, press and hold
the Phones button and press the CR
buttons that correspond to inputs 1
through 4. After you leave the configure
mode, inputs configured for a mono
source will flash during normal operation.
Dub Output Level
The Dub column of orange LEDs will help
you configure two options: dub output level
and dim level. The orange LED in the first
row (number 1 at the top) tells you
whether the dub output is set to –10dBV or
+4dBu. When the LED is off, the dub
output is set to –10dBV; when it’s on, the
dub output is configured for +4dBu.
Dim Level
The dim function is used to reduce the
control room output level a preset amount
whenever you press the Dim button. You
can take a quick phone call without using
the level control to change the control
room level. Also, any time you press the
talk to phones or slate buttons the dim
function is activated.
In the configure mode, LEDs 2 through 4
in the Dub column indicate the selected
dim level. Dim can only have a single
setting, so only one of the orange LEDs
is on at a time.
Row Number Dim Value (dB)
2 25
3 20
4 15
When the orange LED is on in row two,
dim is down 25dB. Dim is down 20dB in
row three, and 15dB in row four. To
change the dim level, hold down the Dub
button while pressing the CR button of
your choice.
