  • Omni-directional (●): Captures sound equally from all directions.
• FILTER Switch: Adjusts noise reduction.
  • NC (Noise Cut): Reduces ambient noise.
  • LC (Low Cut): Reduces low-frequency noise like wind or rumble.
  • OFF: Disables filtering.
• ATT (Attenuation) Switch: Reduces input sensitivity to prevent distortion from loud sounds.
  • 0dB: No attenuation.
  • 10dB: 10 decibel reduction.

4.2 Initial Settings

Before recording, configure the microphone settings based on your environment and recording needs:

• DIGITAL / ANALOG: For optimal audio quality with compatible cameras (e.g., Alpha 7R IV), set to DIGITAL. If your camera is not fully compatible or you prefer analog, select ANALOG. Note that some cameras may only support analog output from this microphone.
• Pickup Pattern: Choose Super-directional for interviews or focusing on a subject, Uni-directional for broader front coverage, or Omni-directional for capturing ambient sounds or multiple speakers around the camera.
• FILTER: Use LC to reduce low-frequency rumble or wind noise. Use NC for general ambient noise reduction. Set to OFF if no filtering is desired.
• ATT: If recording in a loud environment and experiencing audio distortion, switch to 10dB or 20dB attenuation.
• AUDIO LEVEL: For most situations, start with AUTO. For precise control, switch to MAN and adjust the dial while monitoring audio levels on your camera.

5. Operating the Microphone

Once attached and configured, the ECM-B1M integrates seamlessly with your camera's recording functions. Audio is recorded directly through the Multi Interface Shoe, eliminating the need for additional cables or batteries for the microphone itself.

5.1 Recording Audio

1. Ensure all settings on the microphone's control panel are appropriate for your recording scenario.
2. Monitor audio levels through your camera's display or headphones connected to the camera.
3. Begin recording on your camera as usual. The microphone will capture audio according to its current settings.

5.2 Using the Windscreen

For outdoor recording or in windy conditions, attach the included furry windscreen over the microphone capsules. This significantly reduces wind noise, improving audio clarity.

6. Maintenance

6.1 Cleaning

• Wipe the microphone body with a soft, dry cloth.
• Do not use alcohol, benzene, thinners, or other volatile chemicals, as they may damage the finish.
• Clean the Multi Interface Shoe contacts on both the microphone and camera periodically with a dry cloth to ensure good connection.

6.2 Storage

• Store the microphone in its carrying case when not in use to protect it from dust and physical damage.
• Avoid storing in areas with extreme temperatures, high humidity, or direct sunlight.
