Description
SQJ SERIES - MULTIPLE STARQUAD INDIVIDUALLY JACKETED CABLE
A high flexibility multiquad cable for all microphone and line level applications, offering the greatest level of immunity to external noise. Each core comprises a balanced quad (“starquad”), which is used as a twisted pair. Four insulated conductors are twisted together over a Kevlar (Aramid) “synthetic steel” core, with a very short lay length, the insulation thickness on each conductor being closely controlled to match capacitance as closely as possible. The screen is braided, with 95% optical coverage. Each quad is then jacketed with ultraflexible soft PVC, and is numbered along its length for unambiguous termination. A number of these quads are then laid up together with a separate drain wire, and textile filler strands where required to hold the cable shape and achieve the lowest mechanical noise. This is then jacketed overall with matt finish black soft PVC.
