Studio Technologies Model 348 Intercom Station

Studio Technologies Model 348 Intercom Station The Model 348 Intercom Station provides eight independent talk and listen channels that are compatible with Dante audio-over-Ethernet networks. The desktop unit is designed to serve as an audio control center for production and support personnel in numerous applications including on-air television sports and news broadcasting, live events, theater, industrial, and corporate AV. The Model 348's channels can be part of virtual “party-lines” created with other compatible devices or be used directly in point-to-point intercom implementations. The range of resources makes It'simple to use the Model 348 locally, or as part of a REMI or “At-Home” geographically diverse implementation. In addition to intercom applications, the unit can create multiple independent IFB (talent cue) channels. Other applications may benefit from the Model 348 user's ability to easily create monitor mixes from the eight input audio channels. This makes the unit a viable choice for listen-only scenarios.
