Studio Technologies has the Model 5421 Dante Intercom Engine, a high-performance, cost-effective Dante Audio-over-IP (AoIP) party-line intercom solution for up to 16 users.

Studio Technologies Model 5421 The Model 5421 uses an intercom-specific Auto Mix algorithm to optimise party-line audio quality and significantly reduce ambient interference from open mics. The compact half-rackenclosure is intended for use with Studio Technologies’ 370-series of Dante-enabled intercom beltpacks.

Traditional analogue party-line intercom systems, where users can both talk and listen simultaneously in designated production groups, typically require an extensive and dedicated cable infrastructure and often suffer from a high noise-floor and poor voice intelligibility. Studio Technologies has removed these issues by moving 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 only a single RJ45 Ethernet connection for both data and power with minimal set-up via Studio Technologies’ STController software. Its FPGA-based 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 easily configured by routing transmit (output) and receive (input) pairs to the Model 5421 using the Dante Controller software application.
