A high performance range of general purpose extra-flexible twisted twin conductor, helical (“lap”) screened cables, suitable for both microphone and general purpose uses. The cable construction design is the result of extensive research by Canford Audio, and the University of Durham Engineering Department. The outer jacket is an extra-flexible, soft PVC with semi-matt finish.
Construction: Two conductors, each 30 strands of 0.10mm plain copper wire for flexibility, twisted with short lay length (25mm) for better balance and noise rejection. Cotton fillers used both to reduce microphony and to give a more regular central core profile to prevent movement of screen. Precision wound helical formation screen, 72 strands of 0.10mm plain copper wire. Overall jacket is extra flexible soft PVC, which has excellent handling characteristics and remains flexible at low temperatures, together with a serviceable “semi-matt” surface finish
