4. Configuração

1. Desembale o microfone: 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. Monte o microfone: Insert the M30 microphone into the clip. Ensure it is firmly held but not overtightened.
4. Conecte o cabo XLR: 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. Apply Phantom Power: Conecte a outra extremidade do cabo XLR a uma interface de áudio, mesa de mixagem ou pré-amplificador.amplifier that can supply 48V phantom power. The M30 requires 10 mA of current. Ensure phantom power is activated on your device.
6. Posicionamento: 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. Operação

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:

• Posicionamento do microfone: 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.
• Calibração: 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.
• Integração de software: 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.
• Monitoramento de sinal: Monitor the input signal levels to prevent clipping or distortion, ensuring the integrity of your measurements.

6. Manutenção

• Limpeza: 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.
• Armazenar: When not in use, store the M30 in its provided protective case to shield it from dust, moisture, and physical impact.
• Manuseio: Handle the microphone with care. While durable, dropping or subjecting it to severe shocks can affect its calibration and performance.
• Condições ambientais: Avoid exposing the microphone to extreme temperatures or high humidity for prolonged periods.

7. Solução De Problemas

• Sem som:
  • Ensure 48V phantom power is enabled on your audio interface or mixer.
  • Check all XLR cable connections for proper seating and integrity.
  • Verify that the input gain on your audio device is set appropriately.
• Som distorcido:
  • 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.
• Leituras imprecisas:
  • 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.
