4. Operation

4.1 Powering On/Off

The PRO24CM features an on/off switch for convenient operation.

• To turn the microphone ON, slide the switch to the "ON" position.
• To turn the microphone OFF, slide the switch to the "OFF" position.

When using plug-in power from your camcorder, the microphone will draw power directly from the camcorder, and battery operation is not required. However, it is still recommended to turn the microphone off when not in use to conserve battery life if a battery is installed.

4.2 Recording Considerations

• Placement: Position the microphone to capture the desired sound source. The X-Y stereo configuration is designed to provide a natural stereo image.
• Monitoring: Always monitor your audio through headphones connected to your camcorder to ensure optimal sound quality and to detect any unwanted noise.
• Gain Levels: Adjust the input gain on your camcorder to prevent clipping (distortion) while ensuring a strong signal.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the microphone body. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, store the microphone in its protective pouch to prevent dust and damage. Remove the battery if storing for extended periods to prevent leakage.
• Cable Care: Avoid sharp bends or kinks in the microphone cable.

6. Troubleshooting

• No Sound:
  • Ensure the microphone's on/off switch is in the "ON" position.
  • Check if the battery is correctly installed and has sufficient charge. Replace if necessary.
  • Verify the 3.5 mm plug is fully inserted into the camcorder's microphone input.
  • Confirm the camcorder's audio input settings are correct and the input gain is not set to zero.
• Distorted Sound:
  • Reduce the input gain on your camcorder.
  • Ensure the microphone is not too close to the sound source, causing overload.
• Excessive Wind Noise:
  • Ensure the windscreen is properly installed.
  • Consider using an additional furry wind muff for extreme conditions (not included).
