Part #: Barix MA400 SIP Opus Codec
Barix Part #: 2019.9264

The cost-effective MA400 SIP Opus Codec combines the dynamic flexibility and ease of SIP-based link establishment with the quality and efficiency of the open Opus audio compression format. The SIP Opus Codec devices encode or decode audio signals using the open standard Opus codec, a royalty-free audio compression format known for exceptional quality and reliability in interactive speech and music transmission over the Internet. 

The device builds on the Opus codec’s quality, efficiency and low latency with SIP functionality to establish seamless links across SIP-compatible telephone or other IP-based communications systems. Ideal for remote contribution applications, the SIP functionality in the Barix units enables them to dial another device or accept an incoming call and automatically negotiate a transmission link for Opus-based audio streaming. In addition to remote broadcast links, the SIP Opus Codecs offer a reliable, high-quality solution for studio-to-studio (SSL) and studio-to-transmitter (STL) applications at cost-efficient pricing.

Built on Barix’s latest-generation, high-performance IPAM 400 audio module, the MA400 SIP Opus Codec device is a mono, bi-directional device powered by PoE and features analog microphone or line-level input and 5W 8-ohm or line-level output.  It supports audio level supervision with SNMP trap generation and integrates easily with third-party SIP-compliant, Opus-compatible products.
