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.
A configuration feature allows the head-
phone output gain range to be selected.
The low setting is appropriate for most
applications where users need to listen at
moderate levels. The high setting can be
useful when monitoring at higher levels is
warranted by an application.
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 transmitter (output) and receiver
(input) 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 application a simple matter. For exam-
ple, the main audio output channel can
be assigned to the input of an audio con-
sole. The talkback audio output channels
could be assigned to inputs of 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 intercon-
nection is made by way of a Neutrik®
etherCON RJ45 connector. While compat-
ible with standard RJ45 plugs, etherCON
allows a ruggedized and locking intercon-
nection for harsh or high-reliability environ-
ments. The Model 216’s operating power
can be provided by way of the Ethernet
interface using the Power-over-Ethernet
(PoE) standard. This allows fast and
efficient interconnection with the associ-
ated data network. To support PoE power
management, the Model 216’s PoE inter-
face reports to the power sourcing equip-
ment (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.
