Streamer Max MKII

Bidirectional Encoder/Decoder for streaming audio over IP

Bidirectional Encoder/Decoder for streaming audio over IP. Analog and AES/EBU I/O. Formats: PCM, MP3, AAC (separated license required), Vorbis, Shoutcast, Icecast. Distributes audio over standard TCP/IP,LAN,WAN and UMTS networks with external modem. GPIO. Unicast/Multicast.

STREAMER MAX MKII is an hardware device for audio signals encoding / decoding over IP (bidirectional/full duplex).
It is compatible with most of worldwide standards and its architecture is open to support future formats and customizations.
It combines application versatility (Studio, STL, Portable) with ease of use.

STREAMER MAX MKII has both analogue and digital inputs / outputs in order to allow maximum flexibility of installation and connectivity. Specifically designed for broadcast applications, STREAMER MAX MKII is a high quality and high performance device with professional features such as data tunneling for Rs-232 serial port and GPIO management.

STREAMER MAX MKII is also suitable for consumer applications, from audio stream in point-to-point environments to audio distribution for public addressing.
The duty aluminium body, the battery box and the universal power supply allow installation in any kind of environment in any conditions.
