11288 GAC-4/1 V1 FRNC starquad installation cable in white colour
|Gotham "Star-Quad" cables are the most advanced microphone cables presently available. We have combined an ultraflexible PVC-jacket, low capacitive PE insulation, "double 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 RF-rejection is over 130dB (25 kHz). The exclusive double shielding does its part of these features as well.
OFC copper at best standards for best performance.

Starquad wiring instruction 11288 starquad:
In order to benefit from the Starquad concept you need to wire the 4 conductors for you balanced audio cable as follows: (See wiring diagram below)
Bundle each opposite (Star) conductor together,
Pin2= red&ivory (Signal+), Pin3= pink&white (Signal -). Pin1= shield 1&2 =Ground
Put each a few strands of each layer of the shields together to ground Pin 1 should you not have space for all shielding strands.
Cut away any spare strands from the shields and secure that no loose strands are hanging around. Use a shrinking tube to avoid short circuits.
We do not recommend putting any ground to the body shell on either side of your XLR line. The connector shell will get to ground once plugged into a receptacle.
