DSP Board ADAU1401 Howling Suppression Board + USBi Emulator Burner USB Programmer For SigmaStudio

Package Included:
- 1 x DSP Board + USBi Emulator Burner

DSP Board:
Description:
ADAU1401 is a complete single-chip audio system with built-in 28/56-bit audio DSP, ADC, DAC and similar microcontroller control interfaces. Signal processing techniques include equalization, crossover, bass enhancement, multi-band dynamic processing, delay compensation, speaker compensation and stereo image widening, which can be used to compensate for the actual limitations of speakers, power amplifiers, and listening environments, thereby significantly improving sound quality experience.

This signal processing technology is comparable to that used in high-end studio equipment. Most of the processing is done in a fully 56-bit double-precision mode, so low-level signal performance is excellent. ADAU1401 is a fully programmable DSP. With easy-to-use software for SigmaStudio, users can use modules such as biquad filter, dynamic processor, level control, and GPIO interface control to configure custom signal processing procedures in a graphical manner.

ADAU1401 program can be loaded from serial EEPROM through its self-booting mechanism at power-up, or from an external microcontroller. When shutting down, the current state of parameters can be written back to EEPROM from ADAU1401, so that it can be recalled when the program is run next time.

Two ADCs and four DACs provide 98.5 dB of analog input to analog output dynamic range. Utilize digital input and output ports, can realize seamless connection with other ADCs and DACs. The ADAU1401 communicates via the I2C bus or four-wire SPI port.

Application:
- Multimedia speaker system
- MP3 player speaker port
- Car audio host
- Mini stereo system
- Digital Television
- Studio monitor system
- Speaker crossover
- Musical Instrument Sound Processor
- Seat sound system (aircraft/coach)

Uses:
- This version is suitable for ADAU1401/1701 learning and product use. Compared with ADAU1701, ADAU1401 can work stably in the harsh working environment of -40℃ to 105℃ (ADAU1701 is generally applicable under 0℃ to 70℃). The procedures are universal, and other indicators are the same. With power-on self-start, it can run independently from MCU. Leads out all function ports, can expand digital I2S input and output/key function/LED drive/auxiliary ADC (potentiometer analog)/encoder volume adjustment.
- Provide schematic diagrams and many usage routines. By default, a feedback suppression (howling buster) demonstration function is pre-cured and can be replaced with its own function at any time.

USBi Emulator:
Features:
- Enhanced version for factory use is available for the development of simulation and production mass production tools.
- Add self-test function on the official firmware; plug and play, no power-on sequence requirements; aluminum alloy casing, laser engraving will never fade.
- Tri-color status indication: self-test/SPI/I2C.
- Official firmware supports for all SigmaStudioDSP and SHARC series, experience long-term work, dedicated to engineers in the industry, stable /efficient!

Note: Other items pictured are not included, for demonstration purposes only.

- USBi Prohibited Status: Red LED indicates. Red LED will light up when power on, and turn to green after 1sec, indicating that firmware is loaded normally and self-check has passed.
- I2C connection Status: Green light displays, flashing when data is transmitted.


- SPI Connection Status: Blue LED indication.
