4. Operating Instructions
4.1 Microphone Placement
The MD 46 is a cardioid microphone, meaning it is most sensitive to sounds coming from the front and rejects sounds from the sides and rear. For optimal performance during interviews:
- Position the microphone directly in front of the speaker's mouth, typically 4-8 inches away.
- Ensure the microphone grille is pointed towards the sound source.
- In noisy environments, maintaining closer proximity to the speaker will enhance voice clarity and further reduce background noise.
4.2 Handling Noise Reduction
The MD 46 is designed with low handling noise characteristics. To further minimize any unwanted noise from handling:
- Hold the microphone firmly but gently by the handle.
- Avoid rubbing or tapping the microphone body during recording.
- If using a microphone stand, ensure it is stable and isolated from vibrations.
4.3 Wind and Pop Noise
The integrated double-layer grille helps to reduce wind and plosive (P, B sounds) noise. For outdoor use or in situations with strong air movement, consider using an additional foam windscreen (not included) for maximum protection.
5. Maintenance
5.1 Cleaning
To maintain the appearance and performance of your microphone:
- Wipe the microphone body with a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish or internal components.
- Avoid getting moisture into the microphone grille or connector.
5.2 Storage
When not in use, store the microphone in a clean, dry place, away from extreme temperatures and humidity. Using a protective pouch or case (not included) is recommended to prevent dust accumulation and physical damage.
