the associated data network. To support PoE power management,
the Model 216’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 simultaneously.
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 216 configuration settings can be made using twelve DIP
switches and two pushbutton switches. The STcontroller soft
-
ware application can be used to view and change the gain of the
microphone preamplifier and the on/off status of P48 phantom
power. 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
are 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 216’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 bottom 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 216’s back panel.
Multiple 3-position “headers” located on the Model 216’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 216 to be optimized to
meet the needs of specific applications. For example, some ap
-
plications 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 making a few simple
connections. Other applications may benefit from having “mult” or
“loop-through” connections, something easily incorporated into a
Model 216. 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
216’s circuit board. Accessible using 3-pin “header” connectors
they allow specialized configurations to be created. Under soft
-
ware control, the form-A (normally open) solid-state relay contacts
follow the state of the main and talkback 1 pushbuttons. Taking
advantage of the two locations provided for additional XLR con
-
nectors, a technician may easily implement a variety of functions
such as a tally indication or audio muting during talkback.
Firmware Updating
A USB connector, located on the Model 216’s back panel, allows
the operating firmware (embedded software) to be updated us
-
ing a standard USB flash drive. The Model 216 uses Audinate’s
Ultimo™ integrated circuit for implementing Dante. The integrated
circuit’s firmware can be updated via the Ethernet connection,
helping ensure that its capabilities remain up to date.
