Instructions d'installation
- Identifier les connecteurs : The BY-CIP2 cable has two ends: a 3.5mm TRRS male plug (with three black rings on the metal tip) and a 3.5mm TRS female jack (the receptacle).
- Connecter le microphone : Plug your battery-powered 3.5mm stereo microphone (or other audio source) into the 3.5mm TRS female jack of the BY-CIP2 cable. Ensure the microphone is powered on if it requires batteries.
- Connectez-vous à l'appareil : Insert the 3.5mm TRRS male plug of the BY-CIP2 cable into the headphone/microphone combo jack of your smartphone or compatible laptop.
- Vérifiez la connexion : Your device should now recognize an external microphone. You may need to select the external microphone as the input source in your device's audio settings or recording application.

Mode d'emploi
Once the BY-CIP2 cable and microphone are properly connected to your device, you can begin recording audio.
- Open Recording Application: Launch your preferred audio recording application on your smartphone or laptop (e.g., Voice Memos, Camera app for video, third-party recording apps).
- Sélectionnez la source d'entrée : In some applications or device settings, you may need to manually select the external microphone as the audio input source.
- Démarrer l'enregistrement : Initiate recording within your chosen application. The audio will now be captured through the connected external microphone.
- Surveiller l'audio (si possible) : If your recording application or device allows, monitor the audio levels to ensure proper sound capture.

Entretien
To ensure the longevity and optimal performance of your BOYA BY-CIP2 cable, follow these maintenance guidelines:
- Stockage: Rangez le câble dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes. Évitez de l'enrouler trop serré ou de le plier brusquement, car cela pourrait endommager les fils internes.
- Nettoyage: Gently wipe the cable and connectors with a soft, dry cloth to remove dust or dirt. Do not use harsh chemicals or abrasive cleaners.
- Manutention: Lors du branchement ou du débranchement d'un câble, saisissez toujours le boîtier du connecteur plutôt que de tirer sur le câble lui-même. Cela évite toute tension sur les points de connexion.

Dépannage
If you encounter issues while using your BY-CIP2 cable, refer to the following troubleshooting tips:
- Aucune entrée audio :
- Ensure your microphone is alimenté par batterie and its batteries are charged. The BY-CIP2 cable does not provide phantom power.
- Verify that both ends of the cable are securely plugged into the microphone and your device.
- Check your device's audio settings or recording application to ensure the external microphone is selected as the input source.
- Test the microphone directly with another compatible device if possible, to rule out a microphone issue.
- Poor Audio Quality / Signal Degradation:
- Assurez-vous que toutes les connexions sont bien fixées et exemptes de débris.
- Évitez de placer le câble à proximité de sources d'interférences électromagnétiques (par exemple, câbles d'alimentation, routeurs Wi-Fi).
- Test with a different microphone or audio source to determine if the issue lies with the cable or the connected device.
- Check the microphone's settings (gain, sensitivity) to ensure they are appropriate for your recording environment.
- Incompatibility with TRS Microphones (e.g., Rode TRRS to TRS):
- The BY-CIP2 is designed to connect a TRS (stereo) microphone to a TRRS (smartphone) input. If you are trying to convert a TRRS microphone (like some Rode models designed for smartphones) to a TRS input, this cable is not suitable. Ensure your microphone's output type matches the cable's input requirement (TRS microphone into the BY-CIP2's TRS female jack).
