INTERCOM STATION
to the analog inputs on amplified loudspeak-
ers. If a headset is being used and the head-
set dim function is enabled then it’s probably
incorrectly configured and needs to be revised
in STcontroller.
Headset Headphone Output Automatic
Mute
As previously discussed in this guide a setting
in STcontroller allows the headset’s head-
phone output channels to automatically mute
when the microphone source is selected for
Gooseneck. (By default, this function is not
enabled.) This can be useful for users who
frequently change from using a headset and
associated microphone to using a gooseneck.
The unneeded output, either the headset’s
headphone outputs or internal speaker/post-
fader monitor output channels, will auto-
matically mute as the microphone source is
switched. It’s simple to observe this action by
noting that the headset encoder’s knob will
turn purple when the gooseneck microphone
is selected as the source. (Conversely, the
monitor encoder knob will turn purple when
the microphone source is selected for Head-
set.) The muting of the headset’s headphone
outputs can be temporarily overridden by
simply pressing the headset encoder knob.
Monitor Output
The Model 348’s monitor section consists
of a rotary encoder, two Dante audio output
channels, and an internal loudspeaker. These
resources allow a wide range of listening sce-
narios to be implemented.
Monitor Sources and Rotary Encoders
Settings within STcontroller select which of
the eight Dante input channels are routed, by
way of the eight rotary encoders, to the two
monitor output channels. Mixing (summing)
of the selected sources creates the two moni-
tor audio signal buses. The rotary encoder,
labeled Monitor, on the right side of the front
panel, adjusts the level of both the internal
loudspeaker and, if configured for post-fader
(level following the setting of the encoder), the
Dante monitor output channels.
As previously discussed, the loudspeaker and
post-fader monitor output channels can be
muted by pressing the monitor encoder’s knob.
The knob will light purple to indicate that mute
is active. If the signal present function is en
-
abled in STcontroller the encoder’s knob, when
it is not muted, will light green, yellow, or red
to indicate the overall monitor output level. (It
will respond to a monoaural version of the two
monitor channels.) During normal operation it’s
acceptable that the knob lights yellow on occa-
sion. But frequently lighting red would indicate
that the level of either or both monitor output
channels is too high and presents a risk that
signal clipping will occur.
Dante Monitor Output Channels
As previously discussed, two Dante audio
output channels are associated with the Model
348’s monitor section. Several configuration
settings in STcontroller impact the way in which
the monitor output channels function. Eight in-
dependent configuration choices select which
of the eight Dante audio inputs are routed to
either or both of the monitor output channels.
Another configuration setting determines if the
level of the monitor output channels will be
impacted by the monitor rotary encoder. The
Dante monitor outputs can be configured for
post-fader making their signal level respond
to the setting of the Model 348’s monitor level
encoder. If configured for pre-fader the level of
the monitor output channels will not be im-
pacted by the action of the rotary encoder. This
is provided for applications where the monitor
output channels will be routed to devices that
include level control capability. Such devices
would include audio consoles, matrix intercom
systems, and amplified loudspeakers that con-
tain integrated level controls.
