CANFORD SQ-R - STARQUAD MICROPHONE CABLE Ruggedised

CANFORD SQB CABLE 1 quad, Black (BBC PSF4/1C)

Designed for the transmission of sound through noisy areas the balanced quad cable is used as a twisted pair with capacitance unbalance characteristics designed to cancel out the worst kind of interference – external noise. To achieve this four insulated conductors are twisted together with a very short lay length, the insulation thickness on each conductor being closely controlled to match capacitance as closely as possible. Screen is helically wound overall. The product is a flexible high quality cable for use in electrically hostile environments. Core and screen construction conforms to the relevant part of BBC PSF4/1M specification in all cables, as detailed in the Technical Specification below.

This is the same construction as SQ 6.5, but with a matt black polyurethane jacket – incredibly tough and resilient, and which remains flexible in sub-zero arctic conditions. Ideal for outside broadcast and film work, ENG operations, on-stage PA and theatre work.
