SCP 16/4OFC-LSZH-BK-D 4-Core Oxygen-Free Copper Speaker Cable 152m Black

The SCP 16/4OFC-LSZH-BK-D is a professional-grade 4-core speaker cable engineered for high-fidelity audio signal transmission. Utilizing high-purity oxygen-free copper (OFC) conductors, this cable minimizes signal resistance and ensures clear, accurate sound reproduction across long distances. The cable is encased in a Low Smoke Zero Halogen (LSZH) jacket, making it an ideal choice for installations where fire safety and environmental compliance are mandatory requirements.

Advantages

The primary benefit of this cable lies in its oxygen-free copper construction, which provides superior conductivity compared to standard copper cables, effectively reducing signal loss and distortion. The 16 AWG gauge offers a balanced profile suitable for most residential and commercial audio setups. Furthermore, the LSZH jacket provides an essential safety feature by emitting minimal smoke and no toxic halogen gases in the event of a fire, ensuring compliance with strict building codes and safety standards in public spaces.

Suitable for

• Professional home theater audio systems
• Commercial sound distribution in public buildings
• High-end multi-room audio installations
• Educational and corporate AV environments

When it may not be suitable

This cable may not be the optimal choice for outdoor environments exposed to direct sunlight or harsh weather conditions, as the LSZH jacket is primarily designed for indoor safety rather than extreme UV resistance. Additionally, for extremely long cable runs exceeding standard professional recommendations, a thicker gauge wire might be required to prevent voltage drop.

Key specifications

• Conductor material: Oxygen-Free Copper (OFC)
• Number of cores: 4
• Wire gauge: 16 AWG
• Cable length: 152 meters
• Jacket type: Low Smoke Zero Halogen (LSZH)
• Color: Black

How to use

To install the cable, strip the outer LSZH jacket carefully to expose the four internal conductors. Ensure that the wire ends are properly terminated with compatible connectors or secured firmly into speaker terminals to maintain a solid electrical connection. When routing the cable, avoid sharp bends or crushing the jacket to preserve the integrity of the internal copper strands. It is recommended to keep the cable away from high-voltage power lines to prevent electromagnetic interference.

What to consider before purchase

• Verify the required length for your specific installation to ensure the 152-meter spool is sufficient.
• Confirm that the 16 AWG gauge is appropriate for the power requirements of your speakers.
• Check local building regulations to ensure LSZH cabling is required for your specific project.
• Ensure the 4-core configuration matches your wiring topology for stereo or multi-channel setups.

Usage recommendations

For optimal performance, always maintain consistent polarity across all speaker connections. When installing in ceilings or walls, ensure the cable is properly supported and protected from mechanical stress to maintain long-term signal reliability.
