up to indicate that the Dante interface is
not ready. After a short interval it will light
green to indicate that it is ready to pass
data with another Dante device. The SYNC
LED will light red when the Model 214 is
not synchronized with a Dante network. It
will light solid green when the Model 214
is synchronized with a Dante network and
an external clock source (timing reference)
is being received. It will slowly light on and
off green when the Model 214 is part of a
Dante network and is serving as a clock
master.
How to Identify a Specific
Model 214
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 214.
When identify is selected for a specific unit
the SYS and SYNC LEDs on that unit will
together light slowly on and off. This makes
it a very simple task to observe the select-
ed Model 214 unit.
Signal Present/Peak LED
A dual-color LED is located on the Model
214’s back panel, directly below the mi-
crophone input connector. It monitors the
output of the microphone preamplifier,
providing a 3-step signal level indication.
The LED will light green when the signal
level is –40 dBFS or greater, both green
and red at the same time when the signal
level is –14 dBFS or greater, and red when
the signal level is –4 dBFS or greater. Dur-
ing normal operation the LED should light
green and, with peak signals, occasionally
both green and red at the same time. If
the LED is lit constantly green and red at
the same time the gain of the microphone
preamplifier most likely should be reduced.
The LED should never light red only as this
would indicate a signal that’s in danger of
reaching 0 dBFS (digital “clipping”). This
would indicate that the gain of the micro-
phone preamplifier should be significantly
reduced.
Pushbutton Switches and
Status LEDs
Two pushbutton switches are used to
control the audio signals on the main and
talkback output channels. The way each
operates depends on the selected configu-
ration. Three LED indicators are located
adjacent to the pushbuttons and reflect
the status of the audio signals associated
with the main and talkback output chan-
nels. The pushbuttons’ clear lenses are
backlit using white LEDs. The intensity
(brightness) of the LEDs is configured from
a choice of two values, low or high. The
backlighting does not provide an indication
of the associated pushbutton’s status nor
do they serve as a tally function, but rather
allow the pushbutton’s labeling and loca-
tion to be visible in low-light conditions.
Main Button and LED
Indicators
The pushbutton on the left, factory labeled
as COUGH, functions according to the
selected configuration. Two LED indicators,
located directly above the pushbutton, are
associated with the status of the audio sig-
nal on the main output channel. The green
LED, located on the right, is lit whenever
the microphone audio signal is connected
to the main output channel. This could be
considered as an “on-air” or “mic-active”
indicator. If the Model 214’s system mode
is configured to on-air, the red LED, located
on the left, will be lit when the audio signal
associated with main output channel is
muted.
