10421 GAC-2 V1 Similar to GAC-2, improved noise performance (10421 GAC-2 V1 加強抵抗噪音表現)
GAC-2 V1 (10421) also sold under P/N 10420 Balanced double shielded audio cable! Variation to our most popular GAC-2 microphone cable with the same construction as GAC-2 but the PVC-separation (4) has been made out of conductive material to improve the mechanical/noise performance. To improve the capacitance of the cable we have chosen to use PE as isolation material. This is the perfect 2-wire microphone cable without compromise with conductive seperation tube for minimal handling noise for film microphone booms.Similar cables are available as ultrastrong PUR (10502) version and as industrial standard cable for a lower price (10405).
LFOC higher grade copper at best standards for best performance.

Balanced XLR wiring instruction 平衡XLR接線說明:
Pin1= shields, Pin2= brown (Signal+), Pin3= white (Signal -).
Should space not allow to solder all strands of the many shields, you can put only each a few strands of each layer of the shields to ground Pin 1. Cut away any spare strands from the shields and secure that no loose strands are hanging around. Use a shrinking tube to avoid short ciricuits. We do not recommend to put 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.
Pin1=屏蔽層，Pin2=棕色（信號+），Pin3=白色（信號-）。
如果空間不足以焊接所有屏蔽層的銅絲，您可以只將每層屏蔽層的幾根銅絲接地到Pin 1。剪掉屏蔽層上的多餘銅絲，並確保沒有任何鬆散的銅絲懸掛。使用熱縮管以避免短路。我們不建議在XLR線的任一側將任何地線連接到外殼上。一旦插入插座，連接器外殼將接地。
Having your shields put on the connectors shell is dangerous! Imagine, a loose cable can make contact with another loose cable connector having a different ground potential. So the metal connector is conductive and shall not carry your audio ground used on the shieldings of your audio signal. It can interfere with other "grounds" such as video, data of power grounds, which are potentially different! So keep "grounds" separate!
在連線連接器的外殼上安裝屏蔽層是危險的！想像一下，一個鬆動的線材可能與另一個具有不同接地電位的鬆動線材連接器接觸。所以金屬連接器是導電的，不應承載你音訊信號屏蔽的接地。它可能會干擾其他的“接地”，如視頻、資料或電源接地，它們的接地電位可能是不同的！所以要保持“接地”分離！
RCA/Phono/Jack unbalanced wiring using balanced wire RCA/唱臂/6.3插頭非平衡接線:
Many clients use our balanced 2 conductor cable also for unbalanced interconnects. In this case we recommend to only use 1 conductor (brown) for your signal and put all other wires or parts thereof to ground with the shields. This will increase your noise protection! However for unbalanced application we do have our perfect unbalanced wires 1001x, and 1000x.
許多客戶使用我們的四芯線材作為不平衡的連接線。在這種情況下，我們建議只使用一條導線（啡色）作為信號線，並將其他所有導線或其部分接地使用屏蔽。這將增加您的噪音保護！然而，對於非平衡的應用，我們有我們的完美非平衡線1001x和1000x可供使用。
Unbalanced Stereo & 2 Channels (loop) application 非平衡身歷聲及兩聲道應用:
We actually do not support the idea to use a 2 conductor cable for stereo unbalanced wiring, however it will be done and can be made with acceptable compromise regarding crosstalk and similar. Again all the shields to ground but not to the body shell of your XLR connector. Check our perfect stereo cables 12001/13001 or our conductor shielded Starquad 11301 for real quality stereo wiring!
我們實際上不支援使用兩根導體線材進行身歷聲非平衡接線的做法，然而這樣做是可以接受及妥協的，可以在串擾和類似問題方面取得可接受的效果。再次強調，所有屏蔽層都接地，但不要接地到XLR連接器的金屬外殼。
請查看我們的完美身歷聲線材12001/13001或我們的導體屏蔽星絞11301，以獲得真正優質的身歷聲接線體驗！
