Model 201
INTERPRETER’S CONSOLE
Technologies’ products to achieve a sophisticated
voice interpretation system. Applicable companion
units include the Model 391 Dante Alerting Unit, Model
5205 Mic/Line to Dante Interface, Model 5412 Audio
Interface, and Model 5421 Dante Intercom Audio
Engine. Other Dante-compliant products, such as
audio consoles or wireless microphone systems from
other manufacturers, will also directly interface with
the Model 201.
Headphone Output Channels
The Model 201 provides a 2-channel (stereo) output
that is routed to both the 5-pin female XLR and the
3.5 mm TRRS headset interface connectors. Two
pushbutton switches and three rotary controls on the
unit’s front panel allow users to select their desired
headphone audio sources and signal levels. One
pushbutton switch and two associated LED indica-
tors allow direct selection of either the Floor or Relay
Dante receiver (input) audio channels. Floor is the
term in the interpretation world for the audio channel
associated with the person whose text needs to be
translated. It may also be considered to be the “origi-
nal” audio channel. Relay is the term used for an inter-
mediate audio signal that would typically be supplied
by another interpreter. (A “relay” language is usually
selected as an interpretation technique to support
multiple languages. For example, English might be
selected as the relay language.) The selected audio
signal, Floor or Relay, is referred to by the Model 201
as the Main audio source and is sent to both the left
and right headphone outputs. A rotary control allows
the level of the Main audio signal to be adjusted.
Two additional Dante receiver (input) audio channels,
named Aux 1 and Aux 2, can be used to interface the
Model 201 with signal sources such as audio con-
soles, media playback systems, or remotely located
equipment. A rotary level control is used to adjust the
level of both Aux 1 and Aux 2 as they are sent to the
headphone output channels. Conguration choices in
the STcontroller application allow the Aux 1 and Aux 2
signals to be independently routed to the left, right, or
left and right headphone output channels. This allows
a variety of signal sources to be eectively routed to
the headphone outputs.
A separate rotary level control is used to adjust the
level of the Model 201’s microphone preamplifier
signal as it is sent to the headphone output channels.
This is called the sidetone function and provides the
interpreter with a conrmation audio signal. A cong-
uration choice in the STcontroller application is used
to select the routing of the sidetone audio as it is sent
to the left and/or right headphone output channels.
The frequency response of the headphone output
channels can be selected from among four choic-
es: Flat and three equalized (modified response)
settings. Flat provides an unmodied version of the
selected audio signal as it is sent to the headphone
output channels. Choice A causes the low-frequen-
cy contents to be removed from the headphone
output channels. Choice B implements a boost to
the high-frequency range that will impact voice sig-
nals. Choice C combines the low-frequency roll o
of choice A along with the high-frequency boost of
choice B.
These four choices will allow an interpreter to opti-
mize the headphone output signals to best support
their work. A pushbutton switch allows selection of
the desired headphone audio response. Four LED
indicators display the currently selected EQ setting.
Unlike most interpreter console products that provide
analog rotary “tone” controls, the Model 201’s head-
phone equalization functions are created within the
digital domain. This has the advantage of being very
“unit-to-unit” accurate, allowing, for example, an EQ
selection of Choice B on one Model 201 to be identical
with Choice B on other Model 201 units.
Interpret Channels
The Model 201 provides two Dante transmitter (out-
put) channels that are intended for use in interpreta-
tion applications. This allows a Model 201 to support
one or two independent languages or audio paths.
Two pushbutton switches, one associated with each
interpret channel, operate in a latching (push on/
push o) manner. LED status indicators within the
switches display the current status of the interpret
channels. When an interrupt channel is active an
18 kHz sine-wave tone can also be added (summed)
with the microphone signal. This is provided for remote
(networked) applications where an indication that an
interpretation function is active may be required.
The STcontroller application allows selection of
the button color and whether a button is lit when
the function is o. In addition, a conguration selection
determines if only one, or both, of the interpretation
output channels can be active at any one time. A
