About: Studio Technologies Model 5421 Dante Intercom Audio Engine

The Model 5421 Dante® Intercom Audio Engine is a high-performance, cost-effective, flexible solution for creating party-line (PL) intercom circuits. It's directly compatible with the Studio Technologies' range of 1-, 2-, and 4-channel Dante-enabled beltpacks and other interface-related products. The unit is suitable for use in fixed and mobile broadcast facilities, post-production studios, commercial and educational theater environments, and entertainment applications.

Key Features

  • 16-channel audio engine creates multiple virtual party-line (PL) intercom circuits
  • Dante audio-over-Ethernet technology
  • Auto Mix for enhanced audio performance
  • Supports Studio Technologies' intercom beltpacks
  • DDM support and AES67 compliant
  • PoE powered, Gigabit Ethernet interface
  • Configured using STcontroller application
  • Table-top, portable, or optional rack-mount installation


Applications: designed to create from one to four virtual party-line (PL) circuits in Dante audio-over-Ethernet environments
