Studio Technologies has introduced the new Model 5421 Dante intercom engine, a Dante Audio-over-IP (AoIP) party-line intercom for up to 16 users that incorporates an intercom-specific Auto Mix algorithm designed to optimize party-line audio quality and reduce ambient interference from open microphones. The 1/2-rack enclosure is intended for use with Studio Technologies 370-series Dante-enabled intercom beltpacks.
The Model 5421 moves party-line comms to a Dante-based, AES67 and Dante Domain Manger-compatible, Power-over-Ethernet (PoE) approach that uses a standard Ethernet local-area-network (LAN). It requires only a single RJ45 Ethernet connection for both data and power, with set-up via Studio Technologies STController software.
The 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 the single-talk/dual listen Model 372A and Model 373A from Studio Technologies. These compact beltpack units 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 employs a digital-audio algorithm designed for enhanced party-line audio performance. The process automatically adjusts the level of each user’s contribution to a group mix based on an analysis of every input.
“The Model 5421 is ideal for small- and mid-tier performance and production scenarios where users value high-quality audio along with straight-forward ‘set and forget’ convenience,” says Gordon Kapes, president of Studio Technologies. “Dante’s discovery mechanism and pre-configured routing means that beltpacks can be plugged into any port on an associated LAN and intercom operation will automatically begin. The resulting audio performance will far exceed traditional analog systems.”
The Model 5421 hardware offers 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 (1U) of a standard 19-inch rack enclosure.
