請教 AIM NA5 & NA6 用家
想請問一下，如果呢條線用黎駁 player，個方向應該點擺？1. Switch <<<<<<<----------------<<<<<<< Player
2. Switch >>>>>>>------------->>>>>>> Player
謝謝 {:1_249:}

na6沒有
有na5/na9它們線有印">>>"
個人用(2)Switch >>>>>>>------------->>>>>>> Player
(2)Switch >>>>>>>----na5--------->>>>>>> 4k uhd Player
(2)Switch >>>>>>>-----na9-------->>>>>>> ATV
而其它lan線的線有印">>>"方向 同様用(2) 如 mytvsuper / z9x8k / 9100d等等 20120820 發表於 2024-11-25 01:07

咁駁即係條 lan cable shielding ground 會去左 player 個邊，其實個 ground 駁去 switch 個邊理論上會唔會好啲呢？ 要睇你既device, 大部分dac/ streamer 都系ac 3腳插, 但router/switch有好多都dc in所以無ground NA6 都印有>>>>>
方向應該係 switch >>>>> player

呢個你自己試下
此终人人聽感睇感追求不同耳聽為實
個人睇法係廠方出廠時做了方向
為什麽做方向代表廠方測試了証明咁様是最好
當然可以唔跟 之前跟毒友們做了許多不同test 其中有個switch有4個output全用上
(a)4部器材4條lan不同牌子箭咀方向用晒反向(1)
(b)所有跟(a)只係箭咀方向用晒正向(2) 誰好?個人答案(b) 本帖最後由 bbocram 於 2024-11-26 18:43 編輯

呢一間廠既理論同 aim 係相反
Lifted Shield Directional Cable Design
Our CAT7 Ethernet cables are directional in design with regards to how the overall braided shield is terminated on each end of the cable and connectors. So impressed with the performance and low noise floor of our directional Analog RCA cables, we're using the same engineering design principal with our Vivace CAT7 Ethernet cables too. The concept is to attach the overall braided shield within the cable to the shell of the RJ-45 Connector on the "upstream" source end of the cable assembly only. We then lift (detach) the shield on the "downstream" destination end of the cable and connector shell. In other words, there isn't continuity between the two metallic connector shells on either end of the assembled cable. This design creates an "upstream" drain point for RFI/EMI noise & interference without the added risk of tying dis-similar chassis ground potentials together between say, an Internet router and a music streamer or server. In many cases, a user’s router and their stereo gear will be connected to different power outlets or even entirely different A/C circuits within the home. In these cases, if the overall shield is terminated to the connector shells/bodies on both ends of the cable, there's a possibility that doing so would introduce ground hum, ground loops or other anomalies into the signal path by tying two different ground potentials together across this link. By terminating the shield to the metal connector body on the upstream end only (in this scenario the router) and floating it on the downstream end (in this scenario a streamer or music server) the shield acts as a barrier to EMI/RFI along the entire cable length and as a drain to shed noise and leave it at the router ground point.
When you install the Vivace CAT7 Ethernet cables into your system, align the cable with the Avanti Audio logo "arrow" pointing from your "upstream"source device (e.g., router/switch) to your "downstream" destination device (e.g., streamer or server) for best performance.

咁與AIM 何干？
你信又聽落ok 就得。 panerai 發表於 2024-11-26 21:57

都係想知道個理論姐 {:1_258:} bbocram 發表於 2024-11-27 01:47

理論就系best case: switch/router connect ground -> end device float
但router/switch有好多都dc in所以無ground, shielding 做唔到野,
所以系dac/ streamer接地, 呢個系最穩陣既做法
