duced in level or attenuated) by 18 dB
whenever the main or talkback output
channels have audio present. In this way
the three output channels can be used
independently, with none impacting the
other. And, the headphone output can
be connected to amplified loudspeakers.
The speakers will reduce in level when-
ever 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 either or both of the
talkback output channels being ac-
tive. 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 independently, with neither
impacting the other. This also allows all
three pushbuttons to be used simultane-
ously. When selected for the correct ap-
plication, 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 re-
attached. The four rubber bumpers should
be hand-tightened only. No tools should
be used.
Dante
Configuration
A number of the Model 215’s Dante-
related parameters can be configured.
These configuration settings will be stored
in nonvolatile memory within the Model
215’s circuitry. The Model 215 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 uti-
lized. This dictates which parameters can be
configured and what choices are available.
The audio receiver (input) and transmitter
(output) channels associated with the Model
215’s Dante interface must be assigned to
desired sources and destinations. 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® operating systems.
Within Dante Controller a “subscription” is
the term used for routing a transmitter flow
(a group of output channels) 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 direction (two transmit-
ter and two receiver).
The Model 215 has a default Dante device
name of ST-M215 and a unique suffix.
The suffix identifies the specific Model 215
that is being configured. The Model 215
provides four Dante transmitter (output)
channels with the default names of
Main, Talkback 1, Talkback 2, and Tally
Tone/Hot Mic. The Model 215 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 spe-
cific application.
The Model 215 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
