    This Audio DSP Board comes with all the necessary components installed and demonstration
    firmware, and what customers only need to do is to connect and play. Select AA-AP23111 or
    AA-AP23122 and you will get this DSP board shown in Figure 1 or 2.
    Customers will also need an Audio DSP Extension Board with ADAU1701 2 in x 3 out which is
    used to connect the stereo audio player and the audio amplifier (or headphone) by 3.5mm and
    RCA jack. And most of all, it employs the flexible audio DSP connector (10Pin Extension cable
    attached with Extension board). After connecting the Kernel board with interface extension
    board, just power up the kernel board with a universal microUSB cable, and then turn the
    potentiometers on board to adjust main volume, treble volume, bass volume and cut off
    frequncy, besides that toggle the slide switch on board to mute or enable the audio output.
    Select AA-AA11428 to get this interface extension board.
    Thanks for all the available interface of the Audio DSP, including analog and digital audio input
    and output, control IOs and I2C programming interface, this Audio DSP board can provide a
    platform with the ADAU1701 for easy integration of digital audio applications with an affordable



    High Sound Quality

    This Audio DSP board employs the Analog Device ADAU1701 whose signal processing is compara-ble to that found in high end studio equipment. The dynamic range of its Two Σ-Δ ADCs and four Σ-Δ DACs reaches high up to 98.5dB. Each ADC has a THD + N of -83 dB, and each DAC has a THD + N of -90 dB. Besides, the optimal PCB layout of power filtering and signal loop as well as the capacitive compenents also contribute to the high sound quality.


    Affordable price

    Selecting a proper audio DSP module for DIY applications with reasonable speed, cost, precision, data word length, I/O capabilities and SNR is not an easy task usually, especially when budget is only several or tens of dollars. A simplest but available DSP system will only cost you $9.99.The Audio DSP board serves as a cost effective platform for those new to the digital signal processing with interest in digital audio. Simple connection but rich potential configurations and low cost without hidden cost but high performance are the reasons of the affordable price.


    Easy for integration

    If you plan to develope a high performance audio systems, whether a car or a home theater
    focused application, using Kernel Audio DSP board is a turn-key approach to the system develop-ment that free up your development resources to focus on the global performance instead of spending time developing the audio DSP.All the necessary interfaces have been rearranged according to signal chain and the programming requirement. With the headers or a 10 pin cable, the kernel board will be integrated to the mother board quickly.


    Transparent to design resources

    For sake of saving the development investment, we've also attached the schematics, demostra-
    tion project resources and datasheet for the reference. All the files can be downloaded from our
    website store www.sure-electronics.com. If you have further OEM requiremet or application
    questions, please contact our technical support.


    Fully protected

    The ESD and TVS components and resistors arrays are used throughout input and output
    interface in order to avoid plug-in play damage to the ports.
    We also use JST PH side entry connector and IDC connectors to prevent pin connection


    Differences between application and evaluation version

    The differences between application and evaluation version don’t just lie in the prices, which are
    $9.90 and $19.90 respectively.
    There are two control ports on both sides of the evaluation version, each of which has 20 PINs to
    help you integrate the board into your system more easily. Please refer to the PIN definition
    chapter for more details. There is also a reset button on the board to help you restore the
    settings. A molex Micro-Fit 10-PIN is provided to make it more convenient for you to connect it to
    SigmaStudio graphical tool. Besides, it has 4 potentiometers on board for more functions.
    In comparison, there are only 2 potentiometers on the application version board, and it has no
    functions mentioned above.
    In addition, a service of programming can be provided for the application version with a MOQ of
    500 pieces. Feel free to contact with info@sure-electronics.com for more detailed information.


    Transparent to SigmaStudio
    (Fully programmable with SigmaStudio graphical tool)

    The SigmaStudio development environment Analog Device provides a graphical user interface to
    help you build and deploy signal processing systems quickly and efficiently.
    A wide variety of signal processing blocks can be wired together, as in a schematic, and the
    SigmaStudio compiler generates production-ready code while providing a control interface for
    setting and tuning parameters.
    With the programmer USBi connected from PC to the kernel board, real time audio application
    debugging and programming may be implemented flexibly.



    Sure Electronics can provide customers with Analog Devices EVAL-ADUSB2Z for programming. A 10Pin to 6 Pin cable will be provided for easy connection. The Programming kit costs $99.9.     Sure Electronics can also provide another programming device which provides a high cost ratio solution for customers. Please feel free to contact with info@sure-electronics.com for more detailed information.
    Sure Electronics can provide programming service for OEM customers, 500 pieces MOQ and engineering cost will be requested. Please send your requirement document to info@sure-electronics.com for confirmation.
