MODEL 348
INTERCOM STATION
a Model 348 is being used in an environment
where the ambient light is very low or non-
existent. An encoder knob that’s lit dark blue
could be considered as being in its default
state. It’s important to note that there could
be a signal present on the associated Dante
audio input but unless the Signal Present
Display configuration has been enabled the
encoder’s knob will remain dark blue.
An encoder knob that is lit with a purple color
indicates that its associated function has been
muted. To mute or unmute a function simply
requires that the associated encoder knob be
pressed and released (“tapped”).
For user assistance, the LEDs associated
with the eight channel pushbutton switches
can be configured to indicate the approximate
position of each of the rotary encoders. For
this to be active the Level Control Position
Display configuration within STcontroller must
be On (it is by default). There are two means
of observing the level setting associated with
each rotary encoder. One is to press and hold
an encoder’s knob. One or more of the eight
pushbutton switches will light orange. If a
function is muted (minimum level) then push-
button 1 will flash orange. If a function is at full
(maximum) level then pushbuttons 1 through
7 will light orange and pushbutton 8 will flash
orange. The display of the level will continue
until the encoder’s knob is no longer pressed.
The second method of displaying an encod-
er’s level setting is to rotate an encoder knob
at least one step in the clockwise or counter-
clockwise direction. The pushbutton switches
will light orange to display the approximate
level and then hold for approximately one
second past when the last encoder change is
made.
As previously mentioned, 32 encoder steps
(1 and 1/3 full rotations) are required to move
between the minimum and maximum levels.
Each pushbutton switch will light orange in
response to an encoder being within a group
of four steps. So pushbutton 1 will light when
an encoder has been set to steps 1-4, push-
button 2 will light when an encoder has been
set to steps 5-8, etc. Step 1 is considered to
be mute and causes pushbutton switch 1 to
flash orange. Step 32 is the maximum level
and causes pushbuttons 1 through 7 to light
orange and pushbutton 8 to flash orange.
The RGB (red-green-blue) LEDs within the
encoders can shine through the end of the
associated knobs and provide a visual indica-
tion of the level of signal associated with the
encoders’ functions. For the signal level to
be displayed on the knob ends requires that
the Signal Present Display configuration in
STcontroller be selected for On. This is the
default condition and is appropriate for most
applications.
The encoder knobs labeled 1 through 8 will
light in response to the level of signals con-
nected to the associated Dante inputs. As
such they are pre-encoder (also known as
“pre-fader”) which means that the LEDs will
respond to input signal levels prior to any
gain or loss that may be selected by adjust-
ing the associated encoder. An encoder’s
knob will light green to indicate that a signal
is present on the associated Dante input with
a level of –40 dBFS to –16 dBFS. The knob
will light yellow when the signal has a level of
–15 dBFS to –5 dBFS. And the knob will light
red when the signal has a level that meets or
exceeds –5 dBFS.
The encoder knob associated with the head-
set’s headphone output and the encoder knob
associated with the monitor function will also
light at the same level thresholds as the eight
Dante inputs. But there’s a major difference
as their function’s will be post-encoder (also
known as “post-fader”). In this way, the level
indication on these two encoder knobs will
reflect the setting of their associated encoder.
