MODEL 206
ANNOUNCER’S CONSOLE
parameters. This allows the unit’s perfor-
mance to be optimized to meet the needs
of specific applications.
The user is presented with four 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 channels.
Ethernet Data and PoE
The Model 206 connects to a local area net-
work (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 connec-
tor. While compatible with standard RJ45
plugs, etherCON allows a ruggedized and
locking interconnection for harsh or high-
reliability environments.
The Model 206’s operating power is provid-
ed by way of the Ethernet interface using
the 802.3af Power-over-Ethernet (PoE)
standard. This allows fast and efficient inter-
connection with the associated data network.
To support PoE power management, the
Model 206’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 206 using the Dante audio-over-
Ethernet media networking technology. As
a Dante-compliant device, the Model 206’s
four Dante transmitter (audio output) chan-
nels and four Dante receiver (audio input)
channels can be assigned (routed or “sub-
scribed”) to other devices using the Dante
Controller software application. The Dante
transmitter and receiver channels are lim-
ited to supporting 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 indi-
cation of the Dante connection status. An
additional LED displays the status of the
associated Ethernet connection.
The Model 206 is compatible with the
AES67 interoperability standard. In this
mode the four transmitter (output) chan-
nels will function in multicast; unicast is not
supported. In addition, the unit is compat-
ible with the Dante Domain Manager™
(DDM) software application.
Audio Quality
The Model 206’s audio performance is
completely “pro.” A low-noise, wide dy-
namic-range microphone preamplifier and
associated voltage-controlled-amplifier
(VCA) dynamics controller (compressor)
ensures that mic input audio quality is
preserved while minimizing the chance of
signal overload. The output of the micro-
phone 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 do-
main, routes through a 32-bit microproces-
sor 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 206’s microprocessor. The sup-
ported sampling rates are 44.1 and 48 kHz
with a bit depth of up to 24. Channel rout-
ing, headphone level control, and sidetone
creation are performed within the digital
domain. This provides flexibility, allows
