ing international applications where compliance to
specific regulatory requirements is required. This may
dictate which LED color is associated with a function
being “on” and which color is associated with a func-
tion being “off.”
The four Dante receiver (input) audio sources and the
way in which they are assigned to the monitor outputs
can be configured from among five choices. These
unique choices allow a number of audio monitoring
situations to be implemented. Whether for use in
voice paging, talent cueing (IFB), or other audio ap
-
plications, the Model 354 should be able to achieve
the desired configuration. Several special functions
allow the WAV files and gooseneck microphone audio
to be routed to the monitor outputs. Configurable us-
ing STcontroller, these functions can allow a user to
hear confirmation audio related to the unit’s real-time
operation.
Future Capabilities and Firmware
Updating
The Model 354 was designed so that its capabilities
and performance can be enhanced in the future. The
unit implements a USB host function which allows
the application firmware (embedded software) to be
updated using a standard USB flash drive. And, as
previously discussed, the USB receptacle is also
used to load WAV audio files that can be stored on
the same USB flash drive. The Model 354 uses the
Audinate UltimoX4™ integrated circuit to implement
its Dante interface. The firmware in this integrated
circuit can be updated via the Ethernet connection,
helping to ensure that the unit’s capabilities remain
up to date.
Getting Started
What’s Included
Included in the shipping carton is a Model 354 Talk
Station unit along with instructions on how to obtain
an electronic copy of this guide. As the Model 354
is Power-over-Ethernet (PoE) powered, no external
power source is provided. In almost all cases, a
microphone, supplied separately, will be connected
to the Model 354. Studio Technologies recommends
using its GME-3-12 Gooseneck Microphone which
will provide excellent performance. The GME-3-12
is purchased separately and will be shipped in a
separate carton.
Connections
In this section signal interconnections will be made
using the connectors located on the back and front
of the Model 354’s enclosure. One Ethernet connec-
tion will be made using either a standard RJ45 patch
cable or an etherCON protected RJ45 plug. The unit’s
Ethernet interface requires connection of a signal that
supports Power-over-Ethernet (PoE). In most cases,
an electret-powered gooseneck microphone that
has an integrated 1/4-inch plug will be connected to
the jack assembly located on the front of the Model
354’s enclosure. For known excellent performance,
it’s recommended that a Studio Technologies’ GME-
3-12 Gooseneck Microphone be utilized. The analog
monitor output, located on the back of the Model
354’s enclosure, is accessible using a 3-pin male XLR
connector. Some applications may take advantage of
this resource, typically for supporting a local monitor
loudspeaker.
Ethernet Connection
A 100BASE-TX Ethernet (100 Mb/s) connection that
also supports Power-over-Ethernet (PoE) is required
for Model 354 operation. This single connection will
provide both the Ethernet data interface and power
for the Model 354’s circuitry. The Ethernet connection
is made by way a Neutrik etherCON protected RJ45
jack that is located on the back of the Model 354’s
enclosure. This ruggedized and locking RJ45 jack al-
lows connection of an Ethernet signal by way of either
a cable-mounted etherCON connector or a standard
RJ45 plug. The Model 354’s Ethernet interface sup-
ports auto MDI/MDI-X so that a crossover cable is
never required. The Model 354’s Ethernet connection
enumerates itself as a class 1 device. As such, a PoE
power-sourcing-equipment (PSE) port is required to
supply a modest 3.84 watts maximum of power.
Gooseneck Microphone
A mechanical assembly that combines a threaded
bushing with a 3-conductor 1/4-inch jack is incorpo-
rated into the front of the Model 354’s enclosure. This
interface is commonly utilized on professional inter-
com equipment, allowing electrical and mechanical
attachment of a compatible gooseneck microphone.
It’s recommended that the excellent-quality Studio
Technologies’ GME-3-12 Gooseneck Microphone be
utilized. Having an overall length of 12 inches, this
