Model 354
TALK STATION
Broadcast applications can utilize the Model 354 to
create a simple 4-channel talent cue (IFB) master
station. “Program” audio sources can be routed to
the unit’s Dante receiver (input) channels and then
interrupted with gooseneck microphone audio as
desired.
Deployment of Dante applications could benefit from
the unit’s ability to store and playback WAV audio
files. Test messages could be created in WAV format
and then loaded into the Model 354 for continuous
playback during system commissioning.
Security or management personnel could use the
Model 354 as a combination voice paging console
and monitor resource. Audio from the gooseneck
microphone could be immediately routed to up to
four Dante transmitter (output) channels. The monitor
section allows a Dante source to be monitored using
a connected amplifier or amplified speaker.
The range of resources provided by the Model 354
also makes it suitable for use in many other applica
-
tions. It’s designed to support the needs of varied
applications across a wide range of audio system
designs. The unit is intended to provide a “palette” of
resources that meet real-world needs, allowing great
things to be accomplished rather than presenting
limitations that dictate what can and can’t be done.
Setup and Operation
Set up, configuration, and operation of the Model
354 is simple. An RJ45 jack is used to interconnect
with a standard twisted-pair Ethernet port associated
with a PoE-enabled network switch. This connection
provides both power and bidirectional digital audio. A
gooseneck microphone is attached using the ¼-inch
plug with integrated threaded bushing. The Studio
Technologies’ GME-3-12 Gooseneck Microphone is
available as an option and will perform very well with
the Model 354. A 3-pin male XLR connector provides
access to the analog monitor output. This would
typically be connected to the input on an amplified
loudspeaker. The STcontroller software application
is used to configure the wide range of Model 354
operating 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 a push-in/push-out rotary level potentiometer. The
pushbutton switches are lighted with dual-color LEDs
to clearly present the unit’s operating status. The
monitor output (available in both analog and Dante
digital formats) can assist the user in confirming the
current audio operation.
Ethernet Data and PoE
The Model 354 connects to a local area network
(LAN) by way of a 100 Mb/s twisted-pair Ethernet
interface. The unit’s physical 100BASE-TX intercon-
nection is made by way of a Neutrik® etherCON®
RJ45 jack. While compatible with standard RJ45
plugs, etherCON allows a ruggedized and locking
interconnection for harsh or high-reliability environ-
ments. The Model 354’s operating power is provided
by way of the Ethernet interface using the 802.3af
Power-over-Ethernet (PoE) standard. This allows
fast and efficient interconnection with the associated
data network. To support PoE power management,
the Model 354’s PoE interface enumerates (reports)
to the power sourcing equipment (PSE) that it’s a
class 1 (very low power) device.
Dante Audio-over-Ethernet
Audio data is sent to and received from the Model
354 using the Dante audio-over-Ethernet media net-
working technology. As a Dante-compliant device, the
Model 354’s four Dante transmitter (output) channels
