3. Ensure your audio equipment provides ไฟเลี้ยง Phantom 11-52 V. The MC 930 requires phantom power to operate. Activate phantom power on the connected input channel.

4.3 Pre-attenuation and Low-Cut Filter

The MC 930 features two small switches on its body:

• Pre-attenuation Switch (-15 dB): This switch reduces the microphone's output level by 15 dB. Use this setting when recording very loud sound sources (e.g., drums, loud guitar amplifiers) to prevent input clipping on your mixer or interface.
• Low-Cut Filter Switch (80 Hz): This switch activates a high-pass filter at 80 Hz. Use this to reduce unwanted low-frequency noise such as rumble from air conditioning, stage vibrations, or proximity effect when close-miking.

Adjust these switches according to your recording environment and sound source.

5. การใช้งานไมโครโฟน

5.1 รูปแบบขั้วโลก

The MC 930 features a unidirectional (cardioid) polar pattern. This means it is most sensitive to sounds coming from the front and rejects sounds from the sides and rear. This characteristic is ideal for isolating a sound source and minimizing background noise or feedback in live settings.

5.2 การใช้งานที่แนะนำ

The MC 930 is suitable for a variety of applications, including:

• การบันทึกเสียงเครื่องดนตรี: Acoustic guitars, overheads for drums, percussion, strings, woodwinds, and brass instruments.
• บันทึกเสียงร้อง: Speech and singing, especially in controlled studio environments.
• การบันทึกวิดีโอ: Capturing clear audio for video productions.
• เสียงสด: Reinforcement of instruments and vocals on stage.

5.3 การจัดวางที่เหมาะสมที่สุด

Experiment with microphone placement to achieve the desired sound. Generally, placing the microphone closer to the sound source will increase direct sound and reduce room ambience. Utilize the cardioid pattern by pointing the front of the microphone towards the desired sound and away from unwanted noise sources.

6. การบำรุงรักษา

6.1 การทำความสะอาด

To clean the microphone, gently wipe the exterior with a soft, dry, lint-free cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the finish or internal components. Avoid getting moisture into the microphone capsule or switches.

6.2 พื้นที่จัดเก็บ

When not in use, store the MC 930 in its supplied carrying case to protect it from dust, moisture, and physical damage. Store in a cool, dry place.

7 การแก้ไขปัญหา

If you encounter issues with your MC 930 microphone, refer to the following common problems and solutions:

• ไม่มีเสียงออก:
  • Ensure phantom power (11-52 V) is activated on the connected input channel.
  • Check all XLR cable connections for proper seating. Try a different XLR cable.
  • Verify the input gain on your mixer/interface is turned up.
  • Test the microphone on a different input channel or with different audio equipment.
• Distorted or Clipped Sound:
  • Activate the -15 dB pre-attenuation switch on the microphone.
  • ลดค่าเกนอินพุตบนมิกเซอร์/อินเทอร์เฟซของคุณ
  • เพิ่มระยะห่างระหว่างไมโครโฟนกับแหล่งกำเนิดเสียง
• Excessive Low-Frequency Noise/Rumble:
  • Activate the 80 Hz low-cut filter switch on the microphone.
  • Ensure the microphone is isolated from vibrations (e.g., use a shock mount, if available, or place the stand on a stable surface).
• เสียงหึ่งๆ หรือเสียงซ่า:
  • Check for ground loops. Ensure all audio equipment is properly grounded.
  • Ensure XLR cables are balanced and in good condition. Avoid running audio cables parallel to power cables.
  • Test in a different electrical outlet or location to rule out external interference.

If problems persist after trying these steps, contact beyerdynamic customer support or an authorized service center.
