- #24 [audio338], 21-04-08 10:01廠線用 overmold RCA plug 作 video cable,如果焊接手功好,其屏蔽效果最理想。
黃銅插頭不會有磁化問題。
但係工廠為慳工時,通常屏蔽線只焊接一個點。
最後修改時間: 2021-04-08 10:11:13 - #25 [hahayanyan], 21-04-08 10:47如果用普通嘅rca插... 點樣去焊接先至會得到最好嘅屏風效果呢?
- #26 [audio338], 21-04-08 11:15overmold type 見#14及24圖,氹氹轉地焊接一圈,最少3/4圈有上錫。
音頻線用途其屏蔽要求不高的,普通嘅RCA插頭焊一點都ok。
中芯導體的絕緣唔好用pvc,外皮可以用pvc。
最後修改時間: 2021-04-08 11:28:22 - #27 [hahayanyan], 21-04-08 11:36你會不會在 non overmold type rca頭內包多一層 mu metal 之類的東西會有幫助?
- #28 [audio338], 21-04-08 12:30普通嘅RCA插頭帶有金屬外殼, 音頻線用途不需要再包 copper foil tape 或 mu-metal tape。
Locking RCA plug 的地是用一件頭金屬,較一般RCA的接地使用兩件金屬好啲。
Twisted pair wire 已經有效防磁場
干擾。即是 coaxial cable 改用 balanced cable,接線方法見圖,Shielding 只有一個接地點,另一端空接。
如果係連接唱頭要將條線調轉接,即係Shielding 接地點在RIAA Amp input。

thx thx thx - #30 [BB1668], 21-04-08 13:49用Oyadie FTVS- 510純銀同軸線加 SLSC RCA(純銀芯)頭diy左兩條音頻線,聲音真係無得正
- #31 [邱邱邱邱], 21-04-08 19:44唔知點解我試過接ETI厚銅RCA插一頭焊錫接屏蔽銅網,另一邊唔接!
同2邊都唔接網比對過:
一頭接網嘅效果相對豐滿幾多下,連韻味都好幾多,但相對就無甘通透。 - #32 [audio338], 21-04-09 09:28DIY shielded 2 conductor cable, 接線圖見#28。
可以去鴨寮街買 tinned Teflon wire (又稱車佬線) 及 locked RCA plug. CP值高.

- #34 [wm], 21-04-09 10:18请問有師兄代做canare 插頭(收費的),亞歌服務好像唔憂做。请pm我. 谢谢。

can i consider the output from that SUT is single end ? - #36 [mcc2018], 21-04-09 11:20Sure, you can.
- #37 [hahayanyan], 21-04-09 11:28i have a few DIY SUT..around...seem one of them have a center tap ...., it may make sense for having a balance from MC to the SUT ...seem no harm at all
- #38 [hahayanyan], 21-04-09 12:29some said...
for RCA cable
1.8 meter is better than 1meter...............or even in exact 1.82
any sharing about this ?
i have no idea....... at alllllllllll
some said for speaker cable...
4 meter is better than 3.5 meter... and avoid to use "0.5" meter
最後修改時間: 2021-04-09 12:36:22 - #39 [BenYC], 21-04-09 12:48I would not take the measurement too seriously.
Think it was originated from a local magazine "Journey to Sound" probably 20 some years ago. For that issue, someone used a Hitachi Meltone rca cable and keep testing different length to get this conclusion for his setup (if I remember correctly).
For me, I usually kau kei as usual but I rarely go more than 2m unless really necessary. In general, the longer the length, the more pronounced is the cable character thou.
