Operating Instructions
The Aokeo Microphone Isolation Shield is designed to create a more controlled acoustic environment for recording. Its primary function is to reduce ambient noise and minimize sound reflections, leading to cleaner audio.
- Positioning: Place the shield behind or around your microphone, ensuring the acoustic foam interior faces the sound source (e.g., vocalist, instrument).
- Angle Adjustment: The folding panel design allows for angle adjustments. Experiment with different angles to find the optimal setup that best isolates your microphone from unwanted room acoustics.
- Sound Absorption: The high-density sound-absorbing foam sponge effectively absorbs sound waves, preventing them from reflecting back into the microphone.

Maintenance
To ensure the longevity and optimal performance of your Aokeo Microphone Isolation Shield, follow these maintenance guidelines:
- Cleaning: Wipe the exterior surfaces with a soft, dry cloth. For the acoustic foam, gently dust with a soft brush or use a low-power vacuum cleaner with a brush attachment. Avoid using liquid cleaners or abrasive materials.
- Storage: When not in use, fold the shield for compact storage. Store it in a cool, dry place away from direct sunlight and excessive humidity.
- Handling: Handle the shield with care to prevent damage to the acoustic foam or the structural components.
