Versatile IP Audio Decoding for Professional Systems
Barix Exstreamer MR400 is a high-performance Audio over IP decoder designed to bridge modern IP-based audio systems with traditional analog PA infrastructure. It enables seamless integration between network audio streams and existing amplifiers, speakers, or paging systems.
Flexible Integration with IP Audio Ecosystems
The device supports a wide range of enterprise-grade communication platforms including Dante, SIP-based telephony systems, InformaCast, and Syn-Apps Revolution. This ensures compatibility with modern unified communication environments.
Intelligent Audio Management
A built-in priority handler enables automatic switching between multiple audio sources based on defined priority levels. This eliminates the need for external audio matrix systems and ensures uninterrupted delivery of critical announcements.
Relay-Controlled Automation
The integrated relay output allows external device activation such as amplifier switching or signaling systems. Relay can be triggered via audio presence detection or RESTful API commands, making it suitable for automated paging workflows.
Flexible Audio Output Options
MR400 provides both amplified mono output (1W @ 8 Ohm) and symmetric line-level output via screw terminals, along with a 3.5mm output option for flexible installation scenarios.
