MODEL 207
eSPORTS CONSOLE
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 Man-
ager™ (DDM) software application.
Audio Quality
The Model 207’s audio performance is
completely “pro.” A low-noise, wide dynamic-
range microphone preamplifier and asso-
ciated 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 micro-
phone preamp and compressor is routed to
an analog-to-digital conversion (ADC) sec-
tion 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 signals arrive via the four Dante
receiver (input) 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, head-
phone level control, and sidetone creation
are performed within the digital domain. This
provides flexibility, allowing precise control
and keeping the three level potentiometers
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 connect-
ed 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. Selectable parameters include
microphone preamplifier gain, microphone
power source on/off, button operation, head-
phone source routing and control operation,
sidetone operation, and overall unit opera-
tion. In addition, the intensity of the LED
indicators can be configured as desired.
The gain of the microphone preamplifier can
be selected from among five choices. This
allows the Model 207 to match the output
sensitivity of a range of headset-associated
microphones. A source of low-voltage DC
power can be enabled if required to support
electret microphones.
The main and talkback pushbutton switches
can be individually configured. The main but-
ton can be selected to operate from among
six modes while the talkback button can
be selected from among four. These choices
allow the Model 207’s operation to be tai-
lored to meet the specific needs of many
applications. As an example, for an on-air
application the main button might need to be
configured to provide a push to mute (cough)
function. The microphone signal routed to
the Dante main output channel would re-
main active unless a game player needs to
momentarily disable it. The talkback button
would most likely be set to the push to talk
mode as its use would be intermittent.
The audio sources and the way in which
they are assigned to the headphone output
channels and front-panel rotary controls can
be configured from among many choices.
Each choice is unique, allowing almost any
required headphone monitoring situation to
be implemented.
