| Why three conductors for an audio signal? Here are some answers: Grounding/shielding: With the third conductor put to ground, together with the two shields, we have increased RF-rejection to 115dB (20dB better than standard) at 25 kHz. Round Construction: 3-conductor constructions are round constructions, and since the cable has the freedom to move in all directions, especially on the strain relief of a connector, the cable will survive more movement cycles. Phantom Power: The 3rd conductor can be wired as a drain wire for a reliable connection of phantom power to the microphone without affecting the shield. Each of the three conductors consists of 96 (!!) strands of 0.05mm copper wires being the finest stranding for audio cables available which gives you improved flexibility, better signal transport and longer lifetime (moving cycles).

How to wire 3-Conductor cables to XLR connectors 如何將 3 芯線材連接至 XLR 連接器:
3 Conductor cables 10701/10801 will best be wired/soldered as follows:
3 導體線材 10701/10801 最好如下接線/焊接：
Each conductor to each Pin: Pin1= green plus shields, Pin2= brown (Signal+), Pin3= white (Signal -). Put each a few strands of each layer of the shields together with the green conductor to the 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 circuits. 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. The round construction of a 3 conductor cable will give many more moving cycles to your interconnect cable as the perfect round cable will distribute/allow any movement in any direction of the cables bending point at the connectors strain relief. This will give an extremely better (longer) lifespan of your cable.
每根導線連接到每個引腳：引腳1=綠色加屏蔽層，引腳2=棕色（信號+），引腳3=白色（信號-）。將每個屏蔽層的幾股線與綠色導線一起連接到地引腳1。
剪掉屏蔽層上的多餘線束，並確保沒有鬆散的線束。使用收縮管以避免短路。我們不建議在XLR線的任何一側將地線連接到機身外殼。一旦插入插座，連接器外殼會接地。三導體線材的圓形結構將為您的互連線材提供更多的移動迴圈，因為完美的圓形電纜將允許連接器應變緩解處的線材彎曲點在任何方向上的移動。這將極大地提高線材的壽命。
RCA/Phono/Jack unbalanced wiring: Many clients use our 3 conductor perfect round cable also for unbalanced interconnects. In this case we recommend to only use 1 conductor (brown) for you 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.
RCA/唱盤/6.3插頭非平衡接線方法: 許多客戶使用我們的三芯線材作為非平衡的連接線。在這種情況下，我們建議只使用一條導線（棕色）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。
