Studio Technologies MODEL-354A Model 354A Talk Station

The MODEL-354A is a Model 354A Talk Station from Studio Tech.

Studio Technologies MODEL-354A Applications:

• The Model 354A is a versatile solution for theater and live events, handling up to four channels of audio. It supports voice paging, background audio, and pre-configured tones. It can be placed in a box office or manager's office.
• One key feature is its ability to detect and display call signals, providing a visual status of intercom channels. It prevents simultaneous talk function activation and allows monitoring of active channels.
• In broadcast, it serves as a 4-channel talent cue master station, interrupting program audio with gooseneck microphone input.
• For Dante deployments, it stores and plays WAV audio files for testing during system setup.
• Security personnel can use it as a voice paging console, routing audio to Dante transmitter channels and monitoring Dante receiver sources.
• The Model 354A's versatility suits various applications, offering a flexible resource "palette" without limiting capabilities.
