1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your JBL Selenium C521P passive speaker system. Please read this manual thoroughly before using the product to ensure optimal performance and safety.
2. Consignes de sécurité
Respectez toujours les consignes de sécurité suivantes :
- Puissance admissible : Do not exceed the rated power handling of 40W RMS (80W Musical Program) to prevent damage to the speakers.
- Adaptation d'impédance : Assurez votre amplifier or receiver is compatible with an 8 Ohm impedance load. Mismatched impedance can cause damage to both the speakers and the amplifier.
- Ventilation: Ensure adequate ventilation around the speakers, especially if installed in an enclosed space, to prevent overheating.
- Placement: Avoid placing speakers near heat sources, direct sunlight, or in excessively humid or dusty environments.
- Câblage : Always turn off your amplifier/receiver before making any connections. Ensure correct polarity (+ to + and - to -) when connecting speaker wires.
- Nettoyage: Débranchez l'appareil avant de le nettoyer. Utilisez un chiffon doux et sec. Évitez les nettoyants liquides et les aérosols.
- Service: Refer all servicing to qualified service personnel. Do not attempt to open or repair the speakers yourself.

Figure 1 : Arrière view of two JBL Selenium C521P speakers. This image displays the rear panel of two JBL Selenium C521P speakers. Each speaker features a pair of spring-loaded terminal connectors for audio input, typically red for positive and black for negative. The integrated mounting brackets are visible on the sides, allowing for flexible installation. A product label with model number C521P, power handling, and impedance is affixed to the back of each unit.
5. Installation
5.1 Placement des enceintes
Consider the following when positioning your speakers:
- Imagerie stéréoscopique : For optimal stereo sound, place the speakers equidistant from your primary listening position and spaced appropriately apart.
- Montage: The integrated brackets allow for shelf mounting or wall mounting. Ensure the mounting surface is sturdy enough to support the speaker's weight (approximately 2.15 kg per speaker).
- Acoustique de la salle : Experiment with placement to find the best sound balance for your room. Avoid placing speakers directly in corners, which can overemphasize bass.
5.2 Connexions de câblage
Avant d'établir toute connexion, assurez-vous que votre amplifier/receiver is turned OFF.
- Préparer le câble du haut-parleur : Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wires. Twist the bare strands tightly.
- Se connecter au haut-parleur : Press down on the colored tab of the spring-loaded terminal on the back of the C521P speaker. Insert the positive (+) wire (often marked with a stripe or color) into the red terminal and the negative (-) wire into the black terminal. Release the tab to secure the wire.
- Se connecter à Amplifier : Connect the other end of the speaker wire to the corresponding positive (+) and negative (-) speaker output terminals on your amplifier or receiver. Ensure correct polarity for both speakers.
- Vérifier les connexions : Double-check all connections to ensure they are secure and that no stray wire strands are touching, which could cause a short circuit.
Important: Always match the impedance. The C521P speakers have an impedance of 8 Ohms. Refer to your amplifier's manual for compatible speaker impedance ratings.
6. Fonctionnement
Once the speakers are properly connected to your amplificateur/récepteur :
- Mise sous tension : Allumez votre amplificateur/récepteur.
- Contrôle du volume : Commencez par régler le volume à un niveau faible et augmentez-le progressivement jusqu'au niveau d'écoute souhaité.
- Sélection de la source : Select the audio source on your amplificateur/récepteur.
- Apprécier: Your JBL Selenium C521P speakers are now ready for use.
Avoid playing audio at excessively high volumes for extended periods, as this can cause hearing damage and potentially damage the speakers.
7. Entretien
Pour garantir la longévité et les performances optimales de vos haut-parleurs :
- Nettoyage: Use a soft, dry, lint-free cloth to wipe the cabinet and grille. Do not use abrasive cleaners, waxes, or solvents.
- Poussière: Regularly dust the speakers to prevent accumulation, especially on the grille.
- Environnement: Tenez les haut-parleurs à l'écart des températures extrêmes, de l'humidité et de la lumière directe du soleil.
- Entretien des grilles : The aluminum grille is designed for protection. Avoid pressing on it or allowing objects to impact it, which could dent or damage the speaker components underneath.
8. Dépannage
If you encounter issues with your JBL Selenium C521P speakers, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Aucun son ne sort d'un ou des deux haut-parleurs. | Câblage électrique desserré ou incorrect. Amplifier/receiver off or incorrect source selected. Speaker damaged. | Vérifiez que toutes les connexions des câbles d'enceintes sont correctement polarisées et bien fixées. Assurez-vous que amplifier is on and correct input source is selected. Test with another speaker or amplifier si possible. |
| Son déformé. | Volume trop élevé. Amplifier clipping. Incorrect impedance. Damaged speaker. | Réduisez le volume. Assurez-vous amplifier is not overdriven. Verify amplifier impedance compatibility. Inspect speaker for visible damage. |
| Weak or unbalanced sound. | Incorrect balance settings on amplifier. One speaker wired out of phase. | Vérifier amplifier balance controls. Verify speaker wire polarity (+ to + and - to -) for both speakers. |
| Bourdonnement ou vrombissement. | Ground loop. Interference from other electronics. Loose connections. | Ensure all audio components are plugged into the same power outlet or power strip. Separate audio cables from power cables. Check all connections. |
If the problem persists after trying these solutions, contact qualified service personnel.
