MODEL 205
ANNOUNCER’S CONSOLE
be “mix-minus” an integrated sidetone
function can provide the user with a mi-
crophone confidence signal. Three Dante
audio output channels, one designated as
main and two as talkback, are routed via
an associated local-area network (LAN) to
inputs on Dante-compatible devices. Three
pushbutton switches, main and two talk-
back, provide the user with direct control
over audio routing. The audio switching
is performed in the digital domain and is
virtually “click-free.”
By providing the main audio signal in two
forms, Dante digital audio and analog
microphone level, the Model 205 makes
integration into a wide range of on-air en-
vironments easy to accomplish. And with
the two talkback audio channels available
as Dante output channels, routing to inputs
on a variety of devices, such as matrix
intercom systems, audio consoles, and
monitor loudspeaker systems, is simple
and flexible.
Some applications may benefit from not
utilizing the Model 205’s Dante main out-
put channel. This typically won’t be an is-
sue of inadequate audio quality but rather
a need to match work-flow requirements.
For example, for lip-sync or transmission
purposes it may be optimal to have the
on-air audio transported as an embedded
signal along with the associated camera
video. Alternately, all on-air audio sources
may need to connect to inputs on an audio
console or console-related I/O unit. Sup-
porting these scenarios is not a problem
as the Model 205 supplies a microphone
output connection that’s specifically intend-
ed for this purpose. Simply connect the
unit’s microphone output connection to the
desired analog input, such as the mic/line
input on an ENG-style camera—that’s it!
The circuitry associated with the Model
205’s analog microphone output is very
simple, essentially a passive path that
routes a signal connected to the micro-
phone input connector directly to the
microphone output connector. A solid-state
circuit, in series with the mic in-to-mic out
path, allows muting of the signal on the
microphone output connector whenever
the Dante main output channel is muted.
Having both the Dante main output and the
microphone outputs work in tandem can
be a valuable resource, allowing one to
serve as the primary on-air signal source
while the other serves as the backup.
Setup and Operation
Set up, configuration, and operation of
the Model 205 is simple. An etherCON®
RJ45 jack is used to interconnect with a
standard twisted-pair Ethernet port associ-
ated with a PoE-enabled network switch.
This connection provides both power and
bidirectional digital audio. A broadcast
headset or handheld (“stick”) microphone
can be directly connected to the unit’s
3-pin XLR mic input connector. The input
is compatible with dynamic or condenser
microphones. The integrated P48 phan-
tom power source provides support for a
wide range of condenser microphones.
A 3-pin XLR microphone output connec-
tor provides a “direct mic out” function
for integration with microphone inputs on
related devices. Stereo headphones, the
headphone connections from a stereo or
monaural headset, or even a monaural
earpiece can be connected to the phones
output jack. External switches or contact
closures can be connected to the Model
205’s remote control inputs to allow activa-
tion of button functions. The STcontroller
software application is used to configure
the wide range of Model 205 operating
