attenuated) by 18 dB whenever the main
or talkback output channels have audio
present. In this way the two output chan-
nels can be used independently, with
neither impacting the other. And, the
headphone output can be connected
to amplified loudspeakers. The speak-
ers will reduce in level whenever one of
the output channels is active, preventing
acoustical feedback.
• When the system mode is set for produc-
tion, the audio signal on the main output
channel is never muted in response to
the audio signal on the talkback output
channel being active. This mode allows
the main output channel to be used,
for example, as an additional talkback
output. In this way the main and talkback
output channels can be used indepen-
dently, with neither impacting the other.
This also allows both pushbuttons to be
used simultaneously. When selected for
the correct application, the production
mode can prove to be very useful. But
it’s not appropriate for on-air use!
Conclusion
Once the desired configuration has been
established, the security panel can be reat-
tached. The four rubber bumpers should
be hand-tightened only. No tools should
be used.
Dante
Configuration
A number of the Model 214’s Dante-
related parameters can be configured.
These configuration settings will be stored
in nonvolatile memory within the Model
214’s circuitry. The Model 214 uses the
Ultimo 4-input/4-output integrated circuit to
implement the Dante architecture. All four
receiver (input) channels, but only three
of the transmitter (output) channels, are
utilized. This dictates which parameters
can be confi
gured and what choices are
available.
The audio receiver (input) and transmit-
ter (output) channels associated with the
Model 214’s Dante interface must be as-
signed to desired sources and destina-
tions. This will typically be done with the
Dante Controller software application which
is available for download free of charge at
www.audinate.com. Versions are available
to support Windows® and OS X® oper-
ating systems. Within Dante Controller a
“subscription” is the term used for routing
a transmitter flow (a group of output chan-
nels) to a receiver flow (a group of input
channels). Note that as of the writing of this
guide the Ultimo integrated circuit limits the
number of Dante flows to two in each direc-
tion (two transmitter and two receiver).
The Model 214 has a default Dante de-
vice name of ST-M214 and a unique suf-
fix. The suffix identifies the specific Model
214 that is being configured. The Model
214 provides three Dante transmitter (out-
put) channels with the default names of
Main, Talkback, and Tally Tone/Hot Mic.
The Model 214 has four Dante Receiver
(input) channels with default names of
Headphone Ch1, Headphone Ch2,
Headphone Ch3, and Headphone Ch4.
Using Dante Controller these names can
be revised as appropriate for the specific
application.
The Model 214 will support audio sample
rates of 44.1 kHz or 48 kHz with the ability
to select pull-up/pull-down values. These
parameters can be selected using the
Dante Controller application but in most
