Audio modules

Barix has released its IP audio modules for audio streaming applications from real-time audio transmission, audio monitoring and distribution, audio recording, paging, to intercom and warning tone generation systems.

They allow integration of network, audio and interface functionality into standard products or OEM product developments.

The modules can be loaded with a different variety of standard software and can be programmed with OEM specific functionality.

Module 100 is loaded with audio in and audio out ports (stereo), a USB interface for connection to flash sticks and two serial interfaces.

Next to the 10/100 network connection port is a second port which can be configured by firmware to be used for redundancy and daisy chaining. The module allows itself to be universally implemented in almost all audio transmission/audio streaming applications.

Module 200 is a lower cost alternative and suitable for audio output.

It not only streams MP3 files but also WMA/ASF and MMS. Loaded with the standard Exstreamer firmware it allows itself to be individually configured to meet OEM specifications.

Besides the network and audio connections, the module also offers a USB and serial interface as well as digital I/O connections.

Neither module is PC based (no memory fragmentation, no rebooting). The modules use 2 W. A highlight of the module is the USB port which allows the connection of USB flash memory sticks.

Even without the USB stick it is possible to store small audio files in both of the modules' internal memory storage chips and can be updated and played back over the network connection.

Both modules are able to playback audio streams from user-specific software, such as time scheduled announcements (NTP and RTC).
