4. Operating Instructions
To achieve optimal audio recording with your Ultimaxx AS660 microphone:
- Verify Connection: Ensure the 3.5mm plug is fully inserted into your camera's microphone input.
- Positioning: Due to its uni-directional polar pattern, aim the front of the microphone directly towards your sound source for the clearest audio capture and best noise reduction.
- Camera Audio Settings: Access your camera's audio recording settings. Some cameras allow adjustment of input levels. Set the level appropriately to avoid distortion (too high) or low volume (too low).
- Wind Noise Reduction: Always use the foam wind curtain when recording outdoors or in windy conditions to minimize unwanted noise.
- Power: The microphone draws power directly from your camera's microphone input and does not require separate batteries.

The microphone is shown mounted on a camera, which is itself mounted on a tripod, illustrating a typical setup for stable video recording.
5. Maintenance
Proper care will ensure the longevity and performance of your microphone:
- Cleaning: Use a soft, dry cloth to clean the microphone body. Avoid using liquid cleaners or solvents.
- Storage: When not in use, store the microphone in a dry, dust-free environment, preferably in its original packaging or a protective case.
- Foam Wind Curtain: The foam wind curtain can be gently hand-washed with mild soap and water if it becomes dirty. Allow it to air dry completely before reattaching.
- Avoid Impact: Protect the microphone from drops or impacts, as this can damage internal components.
6. Troubleshooting
If you encounter issues with your microphone, refer to the following common problems and solutions:
- No Audio Recording:
- Ensure the 3.5mm plug is fully inserted into the camera's microphone input.
- Check your camera's audio input settings. Some cameras require you to manually select the external microphone input.
- Verify that your camera's recording mode supports external audio input.
- Poor Audio Quality / Low Volume:
- Confirm the microphone is pointed directly at the sound source.
- Adjust your camera's audio input level. If it's too low, the recording will be quiet; if too high, it may distort.
- Ensure the foam wind curtain is properly installed if recording in windy conditions.
- Test the microphone with another compatible camera or device if possible to rule out camera-specific issues.
- Excessive Background Noise:
- The uni-directional pattern helps, but ensure you are in a quiet environment or as close to the sound source as possible.
- Use the foam wind curtain to mitigate wind noise.
