Unleashing the Capabilities of Digital Audio Processor IC Chipset
(ADAU1701)
The ADAU1701 is a single-chip audio system with a 28-/56-bit audio DSP, ADCs, DACs, and micro- controller-like control. It features two ADCs and four DACs, providing a 98.5 dB dynamic range. ADC THD + N is −83 dB, and DAC THD + N is −90 dB. It supports easy connections to additional ADCs and DACs via digital ports, and communication occurs through I2C® or 6-pin JST PH. Note: LED in WONDOM ADSP ADAU1701 Platiorm. The LED colour can be customized. Note: Potentiometer and toggle switch function

Default Cofiguration

1. Power LED
   Indicating the power
   When the device is powered, this LED will be ON.

2. BUSY LED
   BUSY LED is controlled by MP7.
   When MP7 is used as GPIO pin, set at high level, the BUSY LED will be OFF; set at low level, the BUSY LED will be ON. MP7 is not defined now. You can customize its function in SigmaStudio.
   When MP7 is set as 12S1 data input, the LED will be ON when there is signal, OFF when there is no signal.

3. SW1 – Mute Control
   SW 1 functions as mute control.
   When set at 1, device will mute, set at 0, device will unmute.
   The port corresponds to MP0/GPIOO, where OPEN is 1 and SHORTED is 0.

4. SW2 – Phase Control
   SW2 functions as phase control.
   When set at 1, phase is 180°; when set at 0, phase is 0°.
   The port corresponds to MP6/GPIO6, where OPEN is 1 and SHORTED is 0.

5. POT1 – HPF of BANK B
   Potentiometer 1 functions as the High-pass filter for Mid-range output channel (BANK B) and is correspondent with MP3 or ADC2 in program. The default frequen cy adjustment range is 3kHz to 20kHz.
   The adjustable frequency range can be modified through SigmaStudio.

6. POT2 – LPF of BANK A
   Potentiometer 2 serves as the controller for MP8/ADC3. POT2 works as the Low-pass filter for Bass output channel (BANK A). The default frequency adjust ment range is 210Hz to 3kHz.
   The adjustable frequency range can be modified through SigmaStudio.

7. POT3 – HPF of BANK A
   Potentiometer 3 operates as the controller for MP9/ADCO. POT3 serves as the High-pass filter for Bass output channel (BANK A). The default frequency adjust ment range is 10Hz to 310Hz.
   The adjustable frequency range can be modified through SigmaStudio.

8. POT4 – Overall Volume
   Potentiometer 4 functions as Master volume control.
   When rotating POT4 clockwise, the overall volume will increase.
   When rotating POT4 anticlockwise, the overall volume will decrease.

9. Power Supply
   A USB Type-C port is mounted on the rear panel for powering the ADSP1701-2.4U.
   Power supply requirement: DCSV, 1A

10. POTS – Relative Gain Control
    POTS is defined as the Relative Gain Control potentiometer. The control range is -GOdB to OdB.
    When rotating POTS clockwise, the gain of BANK A output remains at OdB, while that of BANK B output channel will gradually attenuate to -60dB.
    When rotating POTS anticlockwise, the gain of BANK B output remains at OdB, while that of BANK A output channel will gradually attenuate to -60dB.
    Please refer to the functional diagram.
    In addition, the functionality of POTS can be customized with SigmaStudio.
    As is shown in the label, POTS is controlled by MP2/ADC1.

11. ICP PORT
    This port is for connection with WONDOM ICP programmer. The unit will support SigmaStudio programming after connection with ICP programmer.
    The PH-6Pos cable comes with ICP programmer.

12. 2CH Audio Input
    The ADSP1701-2.4U supports 2CH analog input with RCA connectors, correspondent to ADCO and ADC1 in the program.

13. 4CH Audio Output
    ADSP1701-2.4U comes with 4 output channels and is integrated with 2-way digital crossover.
    Two channels (DACO&DAC1, BANK A) are dedicated to delivering bass reproduction, while the remaining two channels (DAC2&DAC3, BANK B) handle the mid-range signals.
