Especially when it comes to installations and outfitting of sound studios, many microphone cables have to be laid in cable ducts and wall bushings. The Cordial bulk cable CSF 450 features 2 microphone channels (2x 2 cores) in a common PVC jacket, thus ensuring space-saving installations (~ 6.4 mm diameter / bending radius ~ 33 mm). The wire pairs are protected against interferences and electrical fields by a tinned copper braid. The conductor cross-sections of 4x0.50mm² (AWG 21) provide an optimal signal transmission without "cutting off" high frequencies. The 64 tinned copper strands, each 0.10mm in diameter, ensure high flexibility, especially for fixed installations.
