Studio Technologies Launches 5422A Dante Audio Engine

Skokie, IL (March 22, 2021)—Studio Technologies has released its new enhanced Model 5422A Dante Intercom Audio Engine.

Positioned as a solution for creating party-line (PL) intercom circuits when used with Dante-compatible products, the new “A” version offers an Auto Mix function for enhanced party-line and audio mixing applications. The unit also includes expanded network connectivity with three Gigabit Ethernet ports, aiming to meet the needs of larger, multi-network installations. Additionally, the unit’s main and programmable logic firmware can now be updated using a standard USB flash drive.

The Model 5422A uses Dante audio-over-Ethernet technology to support a variety of broadcast, production and related applications. In addition to creating “virtual” PL intercom circuits, the unit can provide other Dante-based on-air, talent cueing (IFB), audio mixing, and specialized interfacing resources. The Model 5422A features low-latency 32-bit digital processing and is available in two versions – one with 32 input and output channels, and the other with 64 input and output channels.

Auto Mix is an audio level control function that’s implemented in high-speed programmable (FPGA) logic. Not a compressor/limiter or noise gate, the Auto Mix function helps to ensure that all party-line users contribute an equal audio level to an intercom channel. Auto Mix can also be used when using the unit’s audio mixing (summing) mode. The Model 5422A also features an audio control mode that allows multi-channel switching functions to be implemented. High-frequency audio tones provide control of Dante audio input channels that are routed to normally-active and normally-inactive audio output channels.

The Model 5422A offers three Ethernet network connections as compared to the two provided by the Model 5422. Providing three independent “GigE” ports allows two to be designated for Dante redundancy while the third is used to access the Model 5422A’s management port. This allows independent networks to support dual Dante audio paths and the unit’s monitoring and configuration web pages.
