The BLS Series consists of double-isolated loudspeaker cables with twisted conductors and a smooth, flexible PVC outer jacket. Designed for use in public address (100V) audio systems, their durable construction ensures convenient installation and reliable long-term performance.
Built with stranded copper clad aluminum (CCA), these cables combine the lower weight and material cost of aluminum with the improved conductivity and solderability of copper.
Now rated with a CPR Euroclass Eca classification, the BLS Series meets basic fire safety requirements for fixed installations. Always consult local regulations to confirm where Eca class cables are permitted.

Whenever higher-rated cables like B2ca or Cca are not required, Eca class cables offer basic fire safety compliance at an even more cost-effective level. Always consult your local regulations to verify where Eca class cables are permitted.
Copper clad aluminum allows cables to utilize all of the benefits that copper has to offer, while maintaining a much more affordable price tag. CCA is made by bonding a layer of pure copper onto an aluminum core. A CCA core cable obviously contains less copper than a pure copper cable, but it delivers virtually the same conductivity with only slightly higher resistance.
For ease of installation these bulk cables are provided with an indication on every meter of the cable. This enables installers to have a clear and efficient indication of how many meters they still have available on their reel.
