Studio Technologies, Inc. Model 354 Talk Station, Issue 1, Page 2
Applications
For theater or live-event spaces the Model 354 can be a complete
solution for providing up to four channels of background audio
with voice paging and preamble audio capability. Pre-recorded
“tones” or “chimes” can be configured to play prior to voice audio
be presented to one or more of the outputs. The unit could be
located in a box office or manager’s office location.
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 applications. 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 con
-
nected 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 performance 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 physi
-
cal 100BASE-TX interconnection is made by way of a Neutrik®
etherCON® RJ45 jack. While compatible with standard RJ45
plugs, etherCON allows a ruggedized and locking interconnec
-
tion for harsh or high-reliability environments. 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 networking technology. As a
Dante-compliant device, the Model 354’s four Dante transmitter
(output) channels and four Dante receiver (input) channels can be
assigned (routed or “subscribed”) to other devices using the Dante
Controller software application. The Dante transmitter (output)
and receiver (input) channels are limited to supporting four Dante
flows, two in each direction. The digital audio’s bit depth is up
to 32 with a sampling rate of 48 kHz. Two bi-color LEDs provide
an indication of the Dante connection status. An additional LED
displays the status of the associated Ethernet connection.
The Model 354 is compatible with the AES67 interoperability stan
-
dard. When configured in Dante Controller to support AES67, the
unit’s two transmitter (output) channels will function in multicast;
unicast is not supported. In addition, the Model 354 is compatible
with the Dante Domain Manager™ (DDM) software application.
