An eight core speaker cable with 4mm² conductors, rated B2ca-s1a,d0,a1 for fixed installation. The eight cores carry up to four speaker circuits in a single cable, and the larger cross section suits longer runs and lower impedance loads where conductor resistance forms a significant proportion of the total load. Conductors are stranded bare copper to IEC 60228 Class 5, laid up under a PET wrapping tape with a fully extruded LSZH outer jacket. Core insulation is also LSZH, with all eight cores individually colour identified. Overall diameter is 14.3mm.
