JBL Selenium C521P Passive Speaker System User Manual

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. Safety Information

Always observe the following safety precautions:

• Power Handling: Do not exceed the rated power handling of 40W RMS (80W Musical Program) to prevent damage to the speakers.
• Impedance Matching: Ensure your 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.
• Wiring: Always turn off your amplifier/receiver before making any connections. Ensure correct polarity (+ to + and - to -) when connecting speaker wires.
• Cleaning: Disconnect power before cleaning. Use a soft, dry cloth. Avoid liquid cleaners or aerosols.
• Service: Refer all servicing to qualified service personnel. Do not attempt to open or repair the speakers yourself.

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. Setup

5.1 Speaker Placement

Consider the following when positioning your speakers:

• Stereo Imaging: For optimal stereo sound, place the speakers equidistant from your primary listening position and spaced appropriately apart.
• Mounting: 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).
• Room Acoustics: Experiment with placement to find the best sound balance for your room. Avoid placing speakers directly in corners, which can overemphasize bass.

5.2 Wiring Connections

Before making any connections, ensure your amplifier/receiver is turned OFF.

1. Prepare Speaker Wire: Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wires. Twist the bare strands tightly.
2. Connect to Speaker: 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.
3. Connect to 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.
4. Check Connections: 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. Operating

Once the speakers are properly connected to your amplifier/receiver:

1. Power On: Turn on your amplifier/receiver.
2. Volume Control: Start with the volume at a low level and gradually increase it to your desired listening level.
3. Source Selection: Select the audio source on your amplifier/receiver.
4. Enjoy: 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. Maintenance

To ensure the longevity and optimal performance of your speakers:

• Cleaning: Use a soft, dry, lint-free cloth to wipe the cabinet and grille. Do not use abrasive cleaners, waxes, or solvents.
• Dust: Regularly dust the speakers to prevent accumulation, especially on the grille.
• Environment: Keep speakers away from extreme temperatures, humidity, and direct sunlight.
• Grille Care: 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.
