with the main pushbutton switch may be
lit. The user is now presented with three
pushbutton switches, four LEDs, and three
rotary controls. These are simple to oper-
ate and understand, as will be described
in later paragraphs.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
etherCON connector on the Model 215’s
back panel. The LINK/ACT LED will light
green whenever an active connection to
a 100 Mb/s Ethernet network has been
established. 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 Ethernet signal is providing op-
erating power for the Model 215. The SYS
and SYNC LEDs display the operating sta-
tus of the Dante interface and associated
network. The SYS LED will light red upon
Model 215 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 215 is not synchronized with
a Dante network. It will light solid green
when the Model 215 is synchronized with
a Dante network and an external clock
source (timing reference) is being re-
ceived. It will slowly light on and off green
when the Model 215 is part of a Dante
network and is serving as a clock master.
How to Identify a Specific
Model 215
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 215.
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 215
operation will again take place.
Signal Present/Peak LED
A dual-color LED is located on the Model
215’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, occasion-
ally 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 micro-
phone 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 “clip-
ping”). This would indicate that the gain
of the microphone preamplifier should be
significantly reduced.
Pushbutton Switches and
Status LEDs
Three pushbutton switches are used to
control the audio signals on the main and
talkback output channels. The way each
operates depends on the selected con-
figuration. Four 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
