Setup and Operation
Set up, configuration, and operation of the Model 207 is simple.
An etherCON® RJ45 jack is used to interconnect with a stan
-
dard twisted-pair Ethernet port associated with a PoE-enabled
network switch. This connection provides both power and bi-
directional digital audio.
A dual-channel (dual-ear or “stereo”) broadcast headset can
be directly connected to the unit’s 5-pin female XLR connec-
tor. In addition, a 3.5 mm 4-conductor TRRS jack allows direct
connection of gaming-style headsets. For each headset type,
the microphone input is compatible with dynamic or electret
microphones. The integrated low-voltage DC source provides
power support for electret microphones.
A 3.5 mm 3-conductor TRS jack supports connection of a
computer’s analog line-level audio output. The Model 207 takes
this computer audio source and makes it part of the Dante audio
network by first converting it to digital and then outputting it
by way of two Dante transmitter channels. The audio from the
stereo line input can also be configured to be part of the sidetone
confirmation signal that is sent to the headphone output.
The STcontroller software application is used to configure the
wide range of Model 207 operating parameters. This allows
the unit’s performance to be optimized to meet the needs of
specific applications.
The user is presented with two pushbutton switches and three
push-in/push-out rotary level potentiometers. This makes it
easy to control the status of the main and talkback outputs as
well as adjusting the signals that are sent to the headphone
output channels.
Ethernet Data and PoE
The Model 207 connects to a local area network (LAN) by
way of a standard 100 Mb/s twisted-pair Ethernet interface.
The physical 100BASE-TX interconnection is made by way of
a Neutrik® etherCON RJ45 connector. While compatible with
standard RJ45 plugs, etherCON allows a ruggedized and locking
interconnection for harsh or high-reliability environments.
The Model 207’s operating power is provided by way of the
Ethernet interface using the 802.3af Power-over-Ethernet (PoE)
standard. This allows fast and efficient interconnection with the
associated data network. To support PoE power management,
the Model 207’s PoE interface enumerates (reports) to the
power sourcing equipment (PSE) that it’s a class 2 (low power)
device. If a PoE-enabled Ethernet port can’t be provided by
the associated Ethernet switch a low-cost PoE midspan power
injector can be utilized.
Dante Audio-over-Ethernet
Audio data is sent to and received from the Model 207 using the
Dante audio-over-Ethernet media networking technology. As a
Dante-compliant device, the Model 207’s two Dante transmitter
(audio output) channels and four Dante receiver (audio input)
channels can be assigned (routed or “subscribed”) to other
devices using the Dante Controller software application. The
Dante transmitter and receiver channels are limited to support
-
ing four Dante flows, two in each direction. The digital audio’s
bit depth is up to 24 with a sampling rate of 44.1 or 48 kHz.
Two bi-color LEDs provide an indication of the Dante connection
status. An additional LED displays the status of the associated
Ethernet connection.
The Model 207 is compatible with the AES67 interoperability
standard. In addition, the unit is compatible with the Dante
Domain Manager™ (DDM) software application.
Audio Quality
The Model 207’s audio performance is completely “pro.” A
low-noise, wide dynamic-range microphone preamplifier and as
-
sociated voltage-controlled-amplifier (VCA) dynamics controller
(compressor) ensures the headset’s microphone audio quality is
preserved while minimizing the chance of signal overload. The
output of the microphone preamp and compressor is routed to
an analog-to-digital conversion (ADC) section that supports
sampling rates of 44.1 and 48 kHz with a bit depth of up to 24.
The audio signal, now in the digital domain, routes through a 32-
bit microprocessor and on to the Dante interface section where
it is packetized and prepared for transport over Ethernet.
Audio input signals arrive via the four Dante receiver channels
and pass into the Model 207’s microprocessor. The supported
sampling rates are 44.1 and 48 kHz with a bit depth of up to 24.
Channel routing, headphone level control, and sidetone creation
are performed within the digital domain. This provides flexibility,
allowing precise control and keeping the three level potentiom
-
eters from having to directly handle analog audio signals. The
audio channels destined for the phones outputs are sent to a
high-performance digital-to-analog converter and then on to
robust driver circuitry. High signal levels can be provided to the
connected headset or earbuds with microphone.
Configuration Flexibility
The Model 207 can be configured to meet the needs of specific
applications and user preferences. All configuration choices
are performed using the STcontroller software application which
is compatible with version 7 and later of the Windows operat-
ing systems. Selectable parameters include microphone
