Studio Technologie Model 352A Overview

Make announcements while controlling background music with the Studio Technologies Model 352A Talk Station, a tabletop solution that supports a variety of voice paging, background music, audio-file playback, broadcast talent cueing (IFB), and general-audio applications.

With two "talk" channels, the Model 352A can be individually configured to match the needs of an application. The monitor section allows one of two Dante receiver (input) channels to be routed as desired to a connected amplifier or amplified speaker.

At a Glance
  • Dante audio-over-Ethernet technology
  • Supports GME-3-12 gooseneck microphone
  • Voice-paging capability with background music support
  • Broadcast talent cueing (IFB) capability
  • Two independent output channels
  • Analog monitor output with input selection
  • Stores and replays two digital audio (WAV) files
  • Excellent audio quality
  • Uses STcontroller for configuration
  • Power-over-Ethernet (PoE) powered
Dante Compatible
The Model 352A supports Dante audio-over-Ethernet digital media technology with AES67 compatibility for integration into contemporary applications. In addition, the unit is compatible with the Dante Domain Manager (DDM) software application.
Functionality
  • 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 352A.
  • Two audio sources or "messages," up to 40 seconds each in length, are stored in non-volatile memory within the Model 352A. These two audio sources, saved in the common 16-bit monoaural 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.
  • By using WAV files, the desired sources can be created outside of the Model 352A and then easily loaded for use. Configuration choices determine how and when the preamble audio files will be played.

Note: Studio Technologies' GME-3-12 Gooseneck Microphone is highly recommended (sold separately)

Professional Quality, Ease of Use
  • Extremely simple to deploy, is "pro" quality throughout, and provides an intuitive user experience.
  • 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 (sold separately) are required for operation. 
  • 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.
STcontroller Configuration Software
  • Model 352A 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 a myriad of applications. 
  • STcontroller is a fast and simple means of confirming and revising the unit's operating parameters. The Model 352A is housed in a compact, rugged steel enclosure that's intended for tabletop use. Its small size makes it ideal for applications in space-constrained locations.
