BELDEN 7887 SERIES - MULTIPLE STARQUAD INDIVIDUALLY JACKETED CABLE
A high-flexibility, multiquad cable for 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 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 flexible soft PVC, according to a colour code and is numbered along its length. A number of these quads are then laid up together with a separate drain-wire, and then jacketed overall with matt finish, black, soft PVC.
