Skokie, IL (April 14, 2020)—Studio Technologies launches the new Model 5421 Dante Intercom Engine, a Dante Audio-over-IP (AoIP) party-line intercom solution for up to 16 users.

The unit incorporates an intercom-specific Auto Mix algorithm intended to optimize party-line audio quality and reduces ambient interference from open mics. The compact “1/2-rack” enclosure can be used with Studio Technologies’ 370-series of Dante-enabled intercom beltpacks.

The intercom engine is part of an overall system that moves party-line comms to a simple Dante-based, AES67 and Dante Domain Manger-compatible, Power-over-Ethernet (PoE) solution that uses a standard Ethernet local-area-network (LAN).

The Model 5421 requires a single RJ45 Ethernet connection for both data and power with set-up via Studio Technologies’ STController software. Its FPGA-based (field-programmable gate array) mix minus matrix creates a party-line system for up to 16 users. The audio “engine” can be divided into one of five group configurations, ranging from a single 16-user group to four groups of four users. The beltpack’s bidirectional (“4-wire”) Dante audio paths are configured by routing transmit (output) and receive (input) pairs to the Model 5421 using the Dante Controller software application.

The Model 5421 is compatible with all Dante-compatible intercom beltpacks, including single-talk/dual listen Model 372A and Model 373A beltpack units that allow both professional and “gaming” headsets to be utilized. By supporting Dante, the Model 5421 can also be integrated into applications that utilize other audio devices including mixing consoles, user stations, and matrix intercom systems.

When the Auto Mix function is activated, the Model 5421 automatically adjusts the level of each user’s contribution to a group mix based on an analysis of every input to provide a stable group mix combined with a reduction of low-level ambience from open but unused mic sources connected to the group.

The Model 5421 hardware features a single “GigE” RJ45 Ethernet interface for connection to a PoE-port on a standard Ethernet switch. A USB type A connector is available for firmware updates and LED status indicators provide Ethernet network and Dante status monitoring. A rackmount installation kit is also available, allowing one or two Model 5421 units to mounted in one space of a standard 19-inch rack enclosure.
