4x38W amplifier with DSP and BT
Based on:
- 2x Texas Instruments TAS5825M amplifiers
- Qualcomm QCC3031 Bluetooth module
- Atmel Atmega328PB microcontroller
Amplifier / DSP configuration is compiled by the Zoudio Configtool (zoudio.com/configtool)
Configuration is uploaded via the USB/UART connection and saved on an EEPROM
DSP flow is loaded at boot time.
Amplifier is always on, with a low-power (<100uA) 'off' state.
User control and state indication is done via a wiring harness with rotary encoder (on/off + volume), status LED and 3.5mm input.
