Default Configuration

Front Panel

1. Power LED
   Indicating the power When the device is powered, th is 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 Sigma Studio.
   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
   SW1 functions as mute control.
   When set at 1, device will mute, set at 0, device will unmute.
   The port corresponds to MP0/GPIO0, 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 o°;
   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 frequency adjustment range is 3kHz to 20kHz.
   The adjustable frequency range can be modified through Sigma Studio.

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 adjustment range is 210Hz to 3kHz.
   The adjustable frequency range can be modified through Sigma Studio.

7. POT3 – HPF of BANK A
   Potentiometer 3 operates as the controller for MP9/ADC0. POT3 serves as the High-pass filter for Bass output channel (BANK A). The default frequency adjustment range is l0Hz to 310Hz.
   The adjustable frequency range can be modified through Sigma Studio.

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.
   
   Rear Panel

9. Power Supply
   A USB Type-C port is mounted on the rear panel for powering the AOSP1701-2.4U.
   Power supply requirement: OCSV, 1A

10. POTS – Relative Gain Control
    POTS is defined as the Relative Gain Control potentiometer. The control range is -60dB to 0dB.
    When rotating POTS clockwise, the gain of BANK A output remains at 0dB, while that of BANK B output channel will gradually attenuate to -60dB.
    When rotating POTS anticlockwise, the gain of BANK B output remains at 0dB, 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 Sigma Studio.
    As is shown in the label, POTS is controlled by MP2/ADC1.

11. ICPPORT
    This port is for connection with WONDOM ICP programmer. The unit will support Sigma Studio programming after connection with ICP programmer.
    The PH-6Pos cable comes with ICP programmer.Pin| De

Troubleshooting

1. **** Confirm that you downloaded and installed the right software.

ICP3/5 cannot be recognized by the PC|

1. Ensure that you have updated the firmware to the ICP5.
2. Make sure the type-C cable is in good condition and support data communication.
3. Make sure ICP5 is not connected to other device when connected to the PC.
4. Ensure that the WONDOM ICP3/5 board is connected following the correct steps.
5. Ensure that the control pin on the WONDOM ICP5 board is in the correct position.

Amplifier no output sound|

1. Make sure the amplifier is powered at the correct voltage.
2. Make sure the signal I/0 interface connection are correct.
3. Ensure the amplifier is working.
4. Ensure that the amplifier volume is not set to mute.

WONDOM ADSP ADAU1701 cannot work properly (cannot play music) under powering condition when connect with WONDOM ICP5 board|
