Description

This wireless subwoofer amplifier reference design demonstrates the ease of integrating wireless connectivity to a traditional analog input subwoofer design.The wired or wireless mode is controlled by an MSP430. The reference design includes a high performance stereo digital audio amplifier system with software for monitoring and control. The design features the CC8520 PurePath Audio Wireless RF SoC module for audio streaming in wireless mode. Schematics, bill of materials and design considerations for the boards and EVMs used in the reference design are provided.

Features
  • Easy integration of wireless connectivity to analog subwoofer design
  • High performance stereo digital input amplifier system
  • Volume, bass, mute control
  • Selectable bass frequency
  • Wireless Subwoofer system comprising Analog & Wireless Control board, Audio RF SoC module board digital input Class D audio amplier board (EVM), software
  • The design is tested and includes a Quick Start Guide

  • See the Important Notice and Disclaimer covering reference designs and other TI resources.
