headphones, single- or dual-ear broadcast headsets,
and stereo or monaural earpieces or earbuds. As a final
step the Dante Controller personal computer application
will be used to select (route) two audio sources to the
Model 362’s inputs.
Two “push-in/push-out” rotary potentiometers (“pots”)
make it easy for the user to set and maintain the desired
level on the 2-channel headphone output. Four LEDs
provide a clear and complete indication of the unit’s
operating status. The Model 362’s enclosure is made
from an aluminum alloy which offers both ruggedness
and light weight. A stainless steel “belt clip,” located
on the back of the unit, allows direct attachment to a
user’s clothing.
Dante Audio-over-Ethernet
Audio data is sent to the Model 362 using the Dante
audio-over-Ethernet media networking technology.
As a Dante-compliant device, the Model 362’s two
input (Dante receiver) audio channels can be assigned
(routed) from source devices using the Dante Controller
software application. The Model 362 is compatible with
Dante digital audio sources that have a sampling rate
of 44.1, 48, 88.2, or 96 kHz and a bit depth of up to 24.
Two bi-color LEDs provide an indication of the Dante
connection status.
Audio Quality
The Model 362’s performance is completely “pro” with
audio quality that’s more typical of high-end studio equip
-
ment. Audio input signals arrive via the Dante receiver
channels and pass into the Model 362’s processor which
allows signal routing and headphone level control to be
performed within the digital domain. This provides flex
-
ibility, allows precise control, and keeps the two level
potentiometers from directly handling analog audio sig
-
nals. The audio channels destined for the two headphone
output channels are sent to a high-performance digital-
to-analog converter and then on to robust output driver
circuitry. High signal levels can be provided to a variety
of headphones, headsets, and earpieces.
Configuration Flexibility
Several configuration choices are available, allowing the
Model 362 to meet the needs of specific applications and
user preferences. Four DIP switches, located under the
belt clip, facilitate selection of key parameters. Two of
the switches are used to select the headphone output
mode and another switch selects the headphone output
minimum level. The headphone output mode can be con
-
figured from among four choices. The level/level mode is
provided for broadcast applications where two channels
of talent cueing (“IFB”) need to be independently sent to
the left and right headphone output channels. In on-air
sports events it’s typical for program audio with director
interrupt to be sent to the left headphone output while
program-only audio is sent to the right headphone out
-
put. Independent channel level control is provided by the
two potentiometers. The level/balance mode is intended
for applications where a stereo signal is being routed to
the Model 362’s Dante inputs. In this mode the user is
provided with one potentiometer to control the overall
level of both headphone output channels and a second
potentiometer to control the left/right level balance.
The dual-channel monaural mode allows the two Dante
input audio channels to be summed (mixed together) and
