11281 GAC-4/1 V2 Starquad 4-conductor microphone cable (11281 GAC-4/1 V2 星絞四芯麥克風線材)
| Gotham "Star-Quad" cables are the most advanced 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 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 星絞四芯線的接線說明 11288:
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.
為了從星絞四芯的概念中受益，您需要按照以下方式連接您的平衡音頻線材的4根導線：（請參閱下麵的接線圖）
將對角的（星絞）導體捆綁在一起，我們使用了容易識別導體的顏色編碼。（紅色/粉紅色和白色/象牙色屬於一組。）
Pin2 = 紅色和粉紅色（信號+），Pin3 = 白色和象牙色（信號-）。Pin1 = 屏蔽1和2 =地線
如果您沒有足夠的空間容納所有屏蔽線束，請將每個屏蔽層的幾根線束放在一起接地Pin 1。
修剪掉屏蔽線束上的多餘線束，並確保沒有鬆散的線束懸空。使用收縮管以避免短路。
我們不建議在XLR線路的任一側將任何地線連接到機身外殼。一旦插入插座，連接器外殼就會接地。
