The fourth headphone mode uses the left
control to adjust the level of input channel
1, the center control to adjust the level of
input channel 2, and the right control to
adjust the level of both input channels 3
and 4. In this mode the sidetone function
is not active.
The sidetone function allows audio from
the Model 216’s microphone preamplifier
to be routed to the headphone output.
This can be useful, providing the user
with an aural confirmation of the signal
connected to the mic input. It is especially
important when a “mix-minus” talent cue
signal is provided for the user. For appli-
cation flexibility the sidetone function can
be configured from among four choices,
specifying when it will be active in rela-
tion to the status of the main and talkback
functions.
To help minimize the chance of broadcast
cues being missed, the action of the level
controls can be configured so that there’s
always a minimum headphone output
level. Alternately, the controls can be con-
figured to fully mute when they are at their
minimum (fully-counterclockwise) position.
When the level control on the right side is
used for sidetone it will always allow the
sidetone signal to be fully muted.
The headphone output was designed to
meet the needs of contemporary head-
phones and headsets. Specifically, the
output circuits act as voltage drivers rather
than power drivers. In this configuration
they can provide high output levels with
very low distortion and noise, along with
minimal current consumption. The output
circuits can safely drive stereo or mono
loads. This ensures that all types of head-
phones, headsets, and earpieces can be
directly connected.
Dante Audio-over-Ethernet
Audio data is sent to and from the Model
216 using the Dante Audio-over-Ethernet
media networking technology. For flex-
ibility in meeting a variety of sonic require-
ments bit depths of up to 24 and sample
rates of 44.1 and 48 kHz are supported.
Audio output (transmit) and input (receive)
channels on associated Dante-enabled
devices can be assigned to the Model
216 using the Dante Controller software
application. This makes selecting the way
in which the Model 216 fits into an appli-
cation a simple matter. For example, the
main audio output channel can be as-
signed to the input of an audio console.
The talkback audio output channels could
be assigned to inputs on a matrix intercom
system. No special routing or “multing”
using cables or patch points is required
to send the output channels to multiple
destinations. And a single mouse-click
is all that’s required to reroute the audio
signals.
On the input side, the Model 216 allows
up to four headphone cue sources to be
received from an audio console, matrix
intercom system, or a variety of other
Dante-enabled devices; the sources don’t
need to originate from the same device.
“Program” audio could be supplied by
an audio console while “IFB” (interrupted
foldback or talent cue) audio could be
supplied by a matrix intercom system.
Ethernet Data, PoE, and DC
Power Source
The Model 216 connects to a data network
using a standard 100 Mb/s twisted-pair
Ethernet interface. The physical inter-
connection is made by way of a Neu-
trik® etherCON RJ45 connector. While
