Installation, Configuration, and
Operation
Installation, configuration, and operation of the Model 209 is
simple. The lightweight aluminum enclosure mounts under a
tabletop or other work surface. On the unit’s back panel an RJ45
jack is used to interconnect with a standard Ethernet port that
supports Power-over-Ethernet (PoE). This connection provides
both Model 209 power and bidirectional Dante digital audio. Also
located on the unit’s back panel is a 3-pin female XLR connec
-
tor which allows connection of a dynamic, ribbon, or condenser
microphone. The connected microphone can be a standalone
“stick” type, a microphone associated with a broadcast headset,
or a mic installed as part of a microphone mounting assembly. An
integrated low-noise P48 phantom power source allows support
for a wide range of professional condenser microphones.
Stereo or monaural headphones, headsets, or earpieces can be
connected by way of the ¼-inch and 3.5 mm 3-conductor jacks
that are located on the Model 209’s front panel. The headphone
connections on the two jacks are connected in parallel (“mult
-
ed”), providing the same 2-channel signal to various connected
devices. The unit’s two remote control inputs, accessible using
a 3.5 mm 3-conductor jack, allow one or two contact closures
to be connected. These contact closures can be configured to
provide a remote version of the front-panel button function or
to activate the tally output functions. Accessible on a separate
3.5 mm 3-conductor jack, two tally outputs provide DC signals
to operate associated LED status indicators. The tally outputs
are 12 volts DC and can provide up to 100 milliamperes of cur
-
rent. These robust outputs can function independently or as a
single bi-directional current source to ensure compatibility with
a range of microphone on/off status indicators.
The STcontroller software application is used to configure the
Model 209’s many operating parameters. This allows the unit’s
performance to be optimized to meet the needs of specific ap
-
plications. Separate STcontroller versions are available, free of
charge, to support personal computers running the WinOS and
macOS operating systems.
The user is presented with a simple set of controls and indica
-
tors. A lighted pushbutton switch is used to select the status
of the microphone signal as it is sent to the main and talkback
Dante transmitter (output) channels. A rotary level control,
with internal RGB LED lighting, allows on/off control and
level adjustment of the headphone output. An eight-LED multi-
purpose display provides a status indication of various Model
209 operating characteristics.
Ethernet Data and PoE
The Model 209 connects to a local area network (LAN) by way of
a standard 100 Mb/s twisted-pair Ethernet interface. Two LEDs
display the status of the network connection. The Model 209’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 an associated data
network. To support PoE power management, the Model 209’s
PoE interface reports to the power sourcing equipment (PSE)
that it’s a class 2 (low power) device.
Dante Audio-over-Ethernet
Audio data is sent to and received from the Model 209 using the
Dante audio-over-Ethernet media networking technology. As a
Dante-compliant device, the Model 209’s two Dante transmitter
(output) and two Dante receiver (input) audio channels can be
routed (subscribed) to other devices using the Dante Control-
ler software application. The Dante transmitter and receiver
channels are limited to supporting four Dante flows, two in each
direction. The digital audio’s bit depth is up to 32 with supported
sample rates of 48 and 96 kHz. The Model 209 is compatible
with the AES67 interoperability standard. In this mode the two
Dante transmitter (output) channels will function in multicast;
unicast is not supported. In addition, the unit is compatible with
the Dante Domain Manager™ (DDM) software application.
Audio Quality
The Model 209’s audio performance is completely “pro.” A low-
noise, wide dynamic-range microphone preamplifier ensures
that mic input audio quality is preserved while minimizing the
chance of signal overload. The output of the microphone preamp
is routed to a high-performance analog-to-digital conversion
(ADC) section. The audio signal, now in the digital domain,
routes through the unit’s microcontroller integrated circuit and
on to the Dante interface section where it is packetized and
prepared for transport over Ethernet.
