CANFORD SQ AND SQB - STARQUAD MICROPHONE CABLE

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.

SQ

This cable is offered with a variety of jacket colours and diameters. The jacket material is a semi-matt extra-flexible soft PVC, and overall diameter is 4.7mm or 6.5mm. Apart from the jacket material, SQ4.7 conforms to BBC PS4/1M specification.

SQB

This has a standard grade PVC jacket and conforms exactly to BBC PSF4/1M specification.
