IP Audio Module 302

Audio encoding/decoding, one serial port, 4 digital I/O, 3.3V supply.

2012.9129 – IPAM 302 (Sold in quantities of 10, 200 and 1000)

Overview

The IPAM 302 is a universal, standalone, IP Audio function block which can be easily embedded into OEM products. The module encodes and decodes IP Audio streams from/to analog sources (stereo). Supporting a large range of protocols and codecs the module can be used for both VoIP and IP paging as well as high quality music distribution. Barix Annuncicom60 and Instreamer are based on this module. The IPAM302 is pin compatible with the Barix IP AUDIO MODULE 300 (decoder only), adding the full duplex capability on the same form factor and power supply.

Real-World Scenarios

How IP Audio Module 302 solves specific industry challenges.

Bidirectional OEM Intercom Module

A door intercom OEM needs bidirectional audio (both encode and decode) in a 3.3V compatible module for their modern ARM-based product. Module 302's encode/decode capability at 3.3V integrates directly with the product's main processor without voltage level translation.

Video Doorbell Audio Engine

A video doorbell manufacturer needs an IP audio engine for two-way voice. Module 302's 4 digital I/O handle the doorbell button, LED indicators, and relay for door lock, while the codec manages the bidirectional audio — a complete audio and control solution in one module.

Kiosk Intercom Integration

A self-service kiosk manufacturer needs IP audio for customer-to-agent intercom. Module 302 handles both directions of audio and 4 I/O points for kiosk button, speaker amplifier enable, and status LEDs — integrated into the kiosk main board at 3.3V.
