IP Audio Module 300

Low cost version with limited feature set, one serial port, digital I/O, Decoding only, 3.3V supply.

2012.9122 – IPAM 300 (Sold in quantities of 10, 200 and 1000)

Overview

The IPAM 300 is a universal, standalone, IP Audio function block which can be easily embedded into OEM products. The module decodes IP Audio streams and provides the decoded audio as a (stereo) analog or digital (I2S) feed. Supporting a vast range of protocols and codecs the module can be used for both VoIP and IP paging as well as high quality music distribution and IP music streaming applications. Most of the Barix Exstreamer products are based on this module.

Real-World Scenarios

How IP Audio Module 300 solves specific industry challenges.

Budget IP Speaker OEM

A price-sensitive speaker OEM needs a decode-only IP audio module for their entry-level product line. Module 300's low cost and 3.3V supply (compatible with modern SoC systems) provides IP audio decoding without the premium features that add cost for encoding-capable modules.

Smart Home Audio Endpoint

A smart home device manufacturer needs an IP audio decode module for a ceiling speaker product at aggressive retail pricing. Module 300's decode-only design means the product receives and plays IP audio streams without the manufacturing cost of bidirectional codec hardware.

PA Zone Amplifier OEM

A zone amplifier manufacturer needs to add IP audio input to their product at minimal added cost. Module 300 handles IP stream decoding and outputs to the amplifier's existing analog audio chain — the manufacturer adds IP capability without redesigning the amplifier section.
