the associated data network. To support PoE power management,
the Model 214’s PoE interface reports to the power sourcing
equipment (PSE) that it’s a class 2 (low power) device. The unit
can also be powered using an external source of 12 volts DC. For
redundancy, both power sources can be connected simultane
-
ously. If both sources are connected PoE will power the unit. Four
LEDs display the status of the network connection, PoE power
source, and Dante interface.
Configuration and Flexibility
Model 214 configuration settings can be made using twelve DIP
switches and two pushbutton switches. The STcontroller software
application can be used to view and change the gain of the
microphone preamplifier, the on/off status of P48 phantom power,
and the headphone output gain range. The 12-position switch
array configures parameters such as the pushbutton operating
modes, headphone operating mode, sidetone function, and the
overall system mode. The pushbuttons can be used to set the
gain of the microphone preamplifier, control the on/off status
of the microphone P48 phantom power function, and select the
headphone output gain range. The switches and pushbuttons are
accessible via the bottom of the Model 214’s enclosure; the unit
does not have to be disassembled. Changes made to any of the
configuration parameters become active immediately. To prevent
unwanted access to the configuration switches and pushbuttons
a security panel, included with each unit, is attached to the bot
-
tom of the enclosure.
In the world of broadcast and production audio it’s fair to say
that applications vary widely. To this end, one or two additional
XLR connectors can easily be mounted into the Model 214’s back
panel. Multiple 3-position “headers” located on the Model 214’s
circuit board provide technician access to many of the input and
output connections. Using a variety of optional factory-supplied
modules and interface cable kits allows a Model 214 to be opti
-
mized to meet the needs of specific applications. For example,
some applications may prefer to use a multi-pin XLR connector
to interface with a headset. This can easily be accomplished by
installing the appropriate 6- or 7-pin XLR connector kit and mak
-
ing a few simple connections. Other applications may benefit from
having “mult” or “loop-through” connections, something easily
incorporated into a Model 214. And access to the relay contacts
can be made adding a 4-pin XLR connector kit.
Two general-purpose relay contacts are provided on the Model
214’s circuit board. Accessible using 3-pin “header” connec-
tors they allow specialized configurations to be created. Under
software control, the form-A (normally open) solid-state relay
contacts follow the state of the main and talkback pushbuttons.
Taking advantage of the two locations provided for additional XLR
connectors, a technician may easily implement a variety of func
-
tions such as a tally indication or audio muting during talkback.
Firmware Updating
A USB connector, located on the Model 214’s back panel, allows
the operating firmware (embedded software) to be updated us
-
ing a standard USB flash drive. The Model 214 uses Audinate’s
Ultimo™ integrated circuit for implementing Dante. The integrat
-
ed circuit’s firmware can be updated via the Ethernet connection,
helping ensure that its capabilities remain up to date.
