preamplifier gain, microphone power source on/off, button
operation, headphone source routing and control operation,
sidetone operation, and overall unit operation. 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 button 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 tailored 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 remain 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.
There’s even the ability to route two Dante input (receiver)
channels directly to the headphone output channels. In this
configuration the level of the audio signals sent to the head-
phone output will not be impacted by the rotary controls.This
capability is included specifically to support gaming applica
-
tions where a “masking” audio signal needs to be sent to each
player’s headset.
The integrated sidetone function allows audio associated with
the microphone input to be sent to the headphone output. This
is important as different applications may provide either a “full
mix” or a “mix-minus” talent cue signal. If a full mix cue signal
is provided then sidetone audio will not be needed and the func
-
tion can be disabled. In the case where a mix-minus signal is
present, providing the user with sidetone can be an important
means of confirming the signal that’s coming from the connected
microphone.
Three system modes select the overall way in which the Model
207 functions. The on-air mode is optimized for applications
where strict separation between on-air and production audio
channels is required. Other applications will benefit from the
two available production modes.
Future Capabilities and Firmware
Updating
The Model 207 was designed so that its capabilities and per-
formance can be enhanced in the future. A USB connector,
located on the unit’s main circuit board (underneath the unit’s
cover), allows the application firmware (embedded software) to
be updated using a USB flash drive.
The Model 207 uses the Audinate Ultimo™ integrated circuit to
implement the Dante interface. The firmware in this integrated
circuit can be updated via the Ethernet connection, helping to
ensure that its capabilities remain up to date.
