DGS ""Star-Quad"" cables are the most advanced single shielded microphone cables presently available. We have combined an ultraflexible PVC-jacket, low capacitive PE insulation, ""Reussen shielding"" and quad (4-conductor) construction for a truly professional cable at an affordable price.
The ""Star-Quad"" concept is known and recommended where the RF-rejection is the most important factor and where very long cable runs are needed. As we use each 2 conductors for low and high signal, we reduce the signal loss by 50% and due to the offset of the incoming RF-signal by the way the 4 conductors are twisted, the RFrejection is up to 130dB (25 kHz).
