three rotary controls. These are simple to
operate and understand, as will be de-
scribed in later paragraphs.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
etherCON connector on the Model 214’s
back panel. The LINK/ACT LED will light
green whenever an active connection to a
100 Mb/s Ethernet network has been estab-
lished. It will flash on and off in response
to data packet activity. The PoE LED will
light green whenever Power-over-Ethernet
(PoE) associated with the connected Ether-
net signal is providing operating power for
the Model 214. The SYS and SYNC LEDs
display the operating status of the Dante
interface and associated network. The SYS
LED will light red upon Model 214 power
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 syn-
chronized with a Dante network. It will light
solid green when the Model 214 is synchro-
nized 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 net-
work 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 button backlight LEDs will flash. In ad-
dition, the SYS and SYNC LEDs, located
directly below the etherCON connector
on the back panel, will slowly flash green.
After a few seconds the LED identification
patterns will cease and normal Model 214
operation will again take place.
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. During
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 preampli-
fier 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 indi-
cate that the gain of the microphone pream-
plifier 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 configuration.
Three LED indicators are located adjacent to
the pushbuttons and reflect the status of the
audio signals associated with the main and
talkback output channels. 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,
