4. Kurulum

  1. Mikrofonu Paketinden Çıkarın: Carefully remove the M30 microphone and its accessories from the protective case.
  2. Attach the Microphone Clip: Securely fasten the included microphone clip to a suitable microphone stand or boom arm.
  3. Mikrofonu Monte Edin: Insert the M30 microphone into the clip. Ensure it is firmly held but not overtightened.
  4. XLR Kablosunu Bağlayın: Connect a standard XLR cable to the microphone's output. The M30 requires a balanced, transformerless input, with Pin 2 as the positive signal.
  5. Hayalet Gücü Uygulayın: XLR kablosunun diğer ucunu bir ses arayüzüne, miksere veya ön yükselticiye bağlayın.amplifier that can supply 48V phantom power. The M30 requires 10 mA of current. Ensure phantom power is activated on your device.
  6. Konumlandırma: For accurate measurements, position the microphone in the desired location within the acoustic space. Due to its omnidirectional pattern, the microphone picks up sound equally from all directions.

5. Çalıştırma

The Earthworks M30 is designed for precise acoustic measurements. Its omnidirectional polar pattern means it captures sound from all directions uniformly, which is crucial for room analysis and loudspeaker design. To achieve the most accurate results:

  • Mikrofon Yerleşimi: Place the microphone at the listening position or at various points within the room to capture a comprehensive acoustic profile. Avoid placing it too close to reflective surfaces unless specifically intended for boundary measurements.
  • Kalibrasyon: Utilize the included calibration adapter with a 1/2-inch calibrator for field calibration. This ensures the microphone's sensitivity is accurately accounted for in your measurement software, providing correct absolute SPL readings.
  • Yazılım Entegrasyonu: Use the M30 with your preferred acoustic measurement software (e.g., Smaart, MLSSA, SIMM, TEF) to analyze frequency response, phase, and other acoustic properties of your sound system or environment.
  • Sinyal İzleme: Monitor the input signal levels to prevent clipping or distortion, ensuring the integrity of your measurements.

6. Bakım

  • Temizlik: Gently wipe the microphone's stainless steel body with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish or internal components.
  • Depolamak: When not in use, store the M30 in its provided protective case to shield it from dust, moisture, and physical impact.
  • İşleme: Handle the microphone with care. While durable, dropping or subjecting it to severe shocks can affect its calibration and performance.
  • Çevresel Koşullar: Avoid exposing the microphone to extreme temperatures or high humidity for prolonged periods.

7. Sorun Giderme

  • Ses Yok:
    • Ses arayüzünüzde veya mikserinizde 48V fantom gücünün etkinleştirildiğinden emin olun.
    • Tüm XLR kablo bağlantılarının doğru takılıp takılmadığını ve sağlam olup olmadığını kontrol edin.
    • Verify that the input gain on your audio device is set appropriately.
  • Bozuk Ses:
    • Reduce the input gain on your audio device to prevent clipping.
    • Ensure the microphone is not exposed to excessively high sound pressure levels beyond its maximum SPL rating.
  • Yanlış Okumalar:
    • Perform a field calibration using a 1/2-inch calibrator and the provided adapter.
    • Check microphone placement to ensure it is not influenced by unwanted reflections or room modes.
    • Verify that your measurement software is correctly configured for the M30's characteristics.
