Overview
The SFX 4‑Core Speaker Cable is a professional, multi‑core audio installation cable supplied on a 100 m reel. It features oxygen‑free copper (OFC) multi‑strand conductors and Low Smoke Zero Halogen (LSZH) insulation and jacket, making it suitable for use in public and enclosed spaces where reduced toxic emissions are required.

• 100 m reel with four colour‑coded insulated cores (Red, Black, White, Green) inside a pink (RAL 3015) LSZH sheath.
• Oxygen‑free copper (OFC) multi‑strand conductors; 30 × 0.25 mm strands (1.31 mm²) — equivalent to 16 AWG.
• LSZH insulation and outer jacket for low smoke and zero halogen emissions in case of fire.
• Rated voltage 300/500 V; conductor DC resistance <12.6 Ω/km; insulation resistance >200 MΩ/km.
• Operating temperature range −40 °C to +70 °C. CPR classification: Fca.

Why choose this cable?
Designed for professional audio installations, the cable combines low‑resistance OFC conductors with LSZH materials for safer use in public buildings, theatres, schools and other installations where reduced smoke and toxic gas emissions are preferred.

Use cases

• Stereo and multi‑speaker runs in commercial AV installations.
• Bi‑amping or multi‑amp speaker systems requiring separate cores.
• Installations in public or enclosed spaces where LSZH is specified by building regulations or client requirements.

Compliance & safety
CPR classification: Fca as stated on the supplier datasheet. Installations should be carried out by a competent person in accordance with applicable local standards and regulations (e.g. BS 7671 for electrical installation practice where relevant). Check project specifications for any CE/UKCA marking requirements — the supplier datasheet provides CPR info but does not explicitly state CE/UKCA certification.

Installation notes
Use for audio/speaker wiring. Not intended to be used as fixed mains wiring unless the project specification explicitly permits it. Ensure correct polarity and secure terminations to avoid impedance or performance issues.
