3. 操作手順
3.1 電源のオン/オフ
Locate the power switch on the microphone unit. Slide it to the 'ON' position to power on the microphone. Slide it to 'OFF' when not in use to conserve battery life.
3.2 感度調整
The SGC-698 features a sensitivity switch with three settings: -10dB, 0dB, and +20dB. Adjust this setting based on your recording environment and desired audio level.
- 0dB： Standard setting for most recording situations. Provides good bass response for music recording.
- -10dB: Reduces the input gain, useful in loud environments or when recording close to the sound source to prevent distortion. Can also reduce floor noise.
- +20dB: Boosts the input gain, suitable for quiet environments or when recording distant sound sources. Use with caution as it can also amplify background noise.
3.3 ローカットフィルタ
The low-cut filter switch helps to reduce unwanted low-frequency noise, such as wind noise, air conditioner hum, or traffic rumble. Activate this filter when recording in environments prone to such disturbances.
3.4 ウインドスクリーンの使用
For outdoor recording or in windy conditions, attach the included furry windscreen to minimize wind noise and plosives, ensuring clearer audio.

3.5バッテリーインジケーター
When you turn the microphone on, the battery indicator will blink briefly. It will turn a steady red when the battery level is getting low, indicating approximately one hour of recording time remaining before replacement is needed.
4. メンテナンス
適切なメンテナンスを行うことで、マイクの寿命が長くなり、最適なパフォーマンスが確保されます。
- クリーニング： マイクの外装を清掃する際は、柔らかく乾いた布をご使用ください。液体クリーナーや溶剤は使用しないでください。
