3.4 Utilisation du pare-brise

4. Fonctionnement

4.1 Mise sous/hors tension

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 DÉSACTIVÉ, faites glisser l'interrupteur sur la position « ARRÊT ».

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.
  • Surveillance: Always monitor your audio through headphones connected to your camcorder to ensure optimal sound quality and to detect any unwanted noise.
  • Gagner des niveaux : Adjust the input gain on your camcorder to prevent clipping (distortion) while ensuring a strong signal.

5. Entretien

  • Nettoyage: Utilisez un chiffon doux et sec pour nettoyer le corps du microphone. Évitez d'utiliser des produits chimiques agressifs ou des matériaux abrasifs.
  • Stockage: 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.
  • Entretien des câbles : Avoid sharp bends or kinks in the microphone cable.

6. Dépannage

  • Pas de son :
    • Ensure the microphone's on/off switch is in the "ON" position.
    • Vérifiez que la batterie est correctement installée et suffisamment chargée. Remplacez-la si nécessaire.
    • 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.
  • Son déformé :
    • Reduce the input gain on your camcorder.
    • Veillez à ce que le microphone ne soit pas trop près de la source sonore, afin d'éviter toute saturation.
  • Bruit excessif du vent :
    • Vérifiez que le pare-brise est correctement installé.
    • Consider using an additional furry wind muff for extreme conditions (not included).
