Exstreamer MR400

Multiformat IP audio decoder with 1 relay for amplifier activation and amplified/line audio output

The Exstreamer MR400 is a versatile Audio over IP decoder that seamlessly connects IP-based solutions to traditional paging systems, speakers, or amplifiers. It supports a wide range of audio environments including Dante®, SIP, InformaCast, and Syn-Apps, offering flexibility for various setups. With codecs like PCM, AACplus, MP3, OPUS, G.711, and G.722, streamed audio can be delivered via HTTP and RTP protocols. Featuring internal memory for storing audio files, playback can be easily triggered with a simple UDP command. The priority handler allows for seamless switching between sources based on five priority settings, eliminating the need for an audio matrix device. The MR400 is a solid metal device, the compact MR400 is easily installed and offers dual mono audio output. Additionally, it provides relay closure controlled via audio presence or RESTful API. Configuration is simplified through the local web interface.
