Studio Technologies Model 374 Intercom Beltpack

The Model 374 Intercom Beltpack starts with the features offered by traditional broadcast party-line (PL) intercom user devices and adds a range of new features along with the advanced performance and capabilities that Dante® audio-over-Ethernet provides. With four independent talk and listen channels the Model 374 bridges the gap between typical single- and dual-channel party-line devices and permanently installed multi-channel intercom panels. Imagine the possibilities—four channels of high-quality party-line intercom in a compact, user-worn package.

Over a standard IP network, multiple Model 374 units can be used in PL intercom applications with help from an external Dante-enabled audio matrix. Or, units can be used "point-to-point" or directly interfaced with ports on compatible matrix intercom systems. Only a single Power-over-Ethernet (PoE) connection is required for operation. Key user features can be easily configured including preamplifier gain, independent talk button operation, and individual-channel headphone signal routing. User features include integrated sidetone, remote talk channel turn off ("mic kill"), and monitor only modes. This capability, along with the great audio quality provided by the digital audio signal path, offers a unique and powerful user experience.

Set up and configuration of the Model 374 is simple. An etherCON® RJ45 jack is used to interconnect with a standard twisted-pair Ethernet port associated with a local-area network (LAN). This connection provides both power and bidirectional digital audio. A broadcast or intercom-style stereo or monaural headset with a dynamic microphone interfaces with the unit using a 5-pin XLR connector. DIP switches and software-based configuration are used to establish the unit's operating parameters. Four "push-in/push-out" rotary level controls make it easy to set and maintain the desired headphone output. The Model 374's enclosure is made from an aluminum alloy which offers both light weight and ruggedness. A stainless steel "belt clip," located on the back of the unit, allows direct attachment to a user's clothing.

The audio quality of the Model 374's four audio channels is excellent, with low distortion, low noise, and high headroom. Careful circuit design and rugged components ensure long, reliable operation. A wide range of applications can be supported, including sports and entertainment TV and radio events, streaming broadcasts, corporate and government AV installations, and post-production facilities.
