4. Operating Instructions
4.1 Powering On/Off
The BY-MM1 is a plug-and-play microphone and does not require batteries. It draws power directly from the connected device's microphone input. Simply connect the microphone to your device, and it will be ready for use.
4.2 Optimizing Audio Capture
The BY-MM1 features a super-cardioid polar pattern, which means it primarily captures sound from directly in front of the microphone, while reducing sounds from the sides and rear. This is ideal for focusing on a specific sound source and minimizing background noise.
- Positioning: Aim the front of the microphone directly at your desired sound source (e.g., the person speaking).
- Noise Reduction: The included shock mount helps isolate the microphone from vibrations and handling noise. The furry windshield is crucial for outdoor use to reduce wind noise.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the microphone body. Do not use harsh chemicals or solvents.
- Windshield Care: The furry windshield can be gently shaken or brushed to remove dust and debris. Avoid washing it with water.
- Storage: When not in use, store the microphone and its accessories in the provided storage pouch to protect them from dust and damage.
- Cable Care: Avoid sharp bends or excessive pulling on the cables to prevent internal damage.
6. Troubleshooting
- No Audio/Low Volume:
- Ensure the correct cable (TRS for cameras, TRRS for smartphones) is used and fully inserted into both the microphone and the recording device.
- Check your device's audio input settings to ensure the external microphone is selected and the input level is adequate.
- For smartphones, some apps may require specific microphone settings. Try a different recording app if issues persist.
- Excessive Background Noise/Wind Noise:
- Ensure the furry windshield is properly installed, especially in outdoor or windy environments.
- Verify the microphone is correctly positioned, pointing directly at the sound source to utilize its super-cardioid pattern effectively.
- Check for any loose connections or vibrations that might be picked up by the shock mount.
- Distorted Audio:
- Reduce the input gain or volume on your recording device. The microphone may be too close to a loud sound source.
- Ensure the microphone is not physically obstructed.
