Setup Guide
1. Unpacking and Inspection
Carefully remove the APM2 board from its packaging. Inspect the board for any visible damage. Ensure all components are securely attached.
2. Power Supply Connection
The APM2 board requires a 5V DC power supply. Connect the power supply to the designated USB Type-C port on the board. Ensure the power supply provides stable 5V DC.

Note that audio inputs 1, 2, and 3 cannot be used simultaneously, and audio outputs 4, 5, and 6 are available.
4. Programming Interface Connection (Optional)
For advanced configuration and programming using SigmaStudio, connect a WONDOM ICP series programmer (e.g., ICP1, ICP3, ICP5) to the dedicated programming port on the APM2 board. Ensure the correct cable (PH-10Pos for APM3 AA11428, PH-6Pos for ICP programmers) is used.
Operating Instructions
1. Initial Power On
Once all connections are secure, apply power to the board. The power indicator LED should illuminate, indicating the board is operational.
2. Basic Audio Playback
If the board is loaded with a default program, audio should pass through from inputs to outputs. Verify audio output from your connected speakers or headphones.
3. Programming with SigmaStudio
- Install Analog Devices SigmaStudio software on your PC.
- Connect the APM2 board to your PC via a WONDOM ICP programmer.
- Open SigmaStudio and establish communication with the ADAU1701 chip on the APM2 board.
- Design your desired audio processing flow (e.g., EQ, crossover, gain adjustment, time alignment).
- Compile and download the program to the ADAU1701 chip.
- Test the new audio processing effects.
4. Remote Control via PC UI (with ICP Programmer)
Some WONDOM ICP programmers support remote control via a dedicated PC user interface. Refer to the specific ICP programmer's manual for instructions on using its PC UI to adjust parameters on the APM2 board in real-time.
Maintenance
- Cleaning: Keep the board clean and free from dust. Use a soft, dry brush or compressed air to remove dust. Do not use liquid cleaners.
- Environment: Operate the board in a dry, well-ventilated environment, away from extreme temperatures and humidity.
- Handling: Always handle the board by its edges to avoid touching components, especially the DSP chip, which can be sensitive to static discharge.
- Firmware Updates: Periodically check the WONDOM website for any available firmware updates for the ADAU1701 chip or the APM2 board. Follow update instructions carefully.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power indicator light | Incorrect or no power supply connected. | Ensure 5V DC power supply is correctly connected to the USB Type-C port. Check power adapter functionality. |
| No audio output | Incorrect audio connections; DSP program not loaded or incorrect; volume too low. | Verify all audio input/output cables are correctly connected. Ensure a valid DSP program is loaded via SigmaStudio. Check volume levels on source and output devices. |
| Cannot connect to SigmaStudio | ICP programmer not connected or faulty; driver issues; incorrect SigmaStudio settings. | Ensure ICP programmer is properly connected to both the APM2 board and PC. Install necessary drivers for the ICP programmer. Verify communication settings in SigmaStudio. |
| Unexpected audio distortion | Input signal too high (clipping); incorrect DSP settings; faulty components. | Reduce input signal level. Review and adjust DSP parameters in SigmaStudio. If problem persists, contact support. |
