6. Maintenance

To ensure the longevity and optimal performance of your Aokeo Phantom Power Supply, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid using liquid cleaners or solvents.
• Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Cable Care: Handle XLR cables and the power adapter with care to prevent damage to connectors and wiring.
• Ventilation: Ensure the unit has adequate ventilation to prevent overheating.

7. Troubleshooting

If you encounter issues with your phantom power supply, consider the following:

• No Power Indicator: Ensure the power adapter is securely connected to both the unit and a working power outlet. Check the ON/OFF switch position.
• No Sound/Low Sound:
  • Verify all XLR cables are correctly and securely connected between the microphone, phantom power supply, and audio device.
  • Confirm the phantom power supply is turned ON (LED illuminated).
  • Adjust the gain/volume levels on your mixer or audio interface.
  • Note: The phantom power supply provides voltage; it does not amplify the microphone's sound quality or increase its normal volume.
• Humming/Noise: Ensure all cables are properly shielded and connections are tight. Try using different cables to rule out cable issues. Ensure the power supply is not placed too close to other electronic devices that may cause interference.
