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.
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
215 using the Dante audio-over-Ethernet
media networking technology. For flexibility
in meeting a variety of sonic requirements
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 215 using the Dante Controller
software application. This makes selecting
the way in which the Model 215 fits into an
application 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 of a matrix intercom
system. And the tally tone/hot mic audio
output channel could be routed directly to
an amplified speaker for producer or direc-
tor use. No special routing or “multing”
using cables or patch points is required to
send the output channels to multiple des-
tinations. And a single mouse-click is all
that’s required to reroute the audio signals.
On the input side, the Model 215 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 fold-
back or talent cue) audio could be supplied
by a matrix intercom system.
Ethernet Data, PoE, and DC
Power Source
The Model 215 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® ether-
CON RJ45 connector. While compatible
with standard RJ45 plugs, etherCON allows
a ruggedized and locking interconnection
for harsh or high-reliability environments.
The Model 215’s operating power can be
provided by way of the Ethernet interface
using the Power-over-Ethernet (PoE) stan-
dard. This allows fast and efficient intercon-
nection with the associated data network.
To support PoE power management, the
Model 215’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
