Description
KSM SERIES - OVERALL FOIL SCREENED SOLID CONDUCTOR MULTIPAIR CABLE (BBC PSN types)
These cables, to a BBC specification, have single solid conductors, twisted in pairs and overall foil screens with drain wire. They are suitable for permanent installations where screens are terminated on a bus arrangement, such as jackfields and IDC type blocks. They have a relatively low impedance (they were designed before digital audio was invented) and are not suitable for digital audio circuits.
