TALK STATION
Introduction
The Model 354 Talk Station is a unique product
intended to support a variety of voice paging, back-
ground music, audio-file playback, broadcast talent
cueing (IFB), and general audio applications. The
unit supplies four independent “talk” channels that
can be individually configured to match the needs of
an application. A simple monitor section allows one
of the four Dante® receiver (input) channels to be
routed as desired to a connected amplifier or ampli-
fied speaker.
The Model 354 supports Dante audio-over-Ethernet
digital media technology with AES67 compatibility
for integration into contemporary applications. In ad
-
dition, the unit is compatible with the Dante Domain
Manager™ (DDM) software application.
Voice audio is supplied by way of a gooseneck
microphone, purchased separately, which is attached
to the connector/threaded bushing combination that
is located on the front of the Model 354. (Using the
Studio Technologies’ GME-3-12 Gooseneck is highly
recommended.) Two audio sources or “messages,”
up to 40 seconds each in length, are stored in non-
volatile memory within the Model 354. These two
audio sources, saved in the common 16-bit monoau-
ral WAV format, can be easily updated by way of a
standard USB flash drive. The audio files can contain
whatever “pre-page” (preamble) audio signals that are
desired to support an application. They could be the
sound of natural bells or chimes, an “electronically
created” audio sequence, or a voice message. By
using WAV files, the desired sources can be created
outside of the Model 354 and then easily loaded for
use. Configuration choices determine how and when
the preamble audio files will be played.
The Model 354 is extremely simple to deploy, is “pro”
quality throughout, and provides an intuitive user ex
-
perience. The Model 354’s audio quality is excellent,
with low distortion, low noise, and ample headroom.
Careful circuit design and rugged components ensure
long, reliable operation. Only a Power-over-Ethernet
(PoE) connection and attachment of a gooseneck
microphone are required for operation. If desired, the
analog monitor output can be connected to the input of
an associated device. Two “custom” WAV audio files
can be loaded by way of a USB flash drive.

Model 354 operating features are configured using the
STcontroller software application. An extensive set of
parameters allows the unit’s functions to be tailored
to meet the needs of many, many applications.
STcontroller is a fast and simple means of confirm-
ing and revising the unit’s operating parameters. The
Model 354 is housed in a compact, rugged steel en-
closure that’s intended for table-top use. Its small size
makes it ideal for applications in space-constrained
locations.
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.
