我用DAC試過一邊用平衡接耳擴令一邊用rca接AMP,
AMP聲音會差左小小!
·針冇兩頭利，鬼叫我自己想玩耳擴咁先对得住用緊嘅K702 hksarac 發表於 2015-10-11 12:01
請講清楚RCA線和同軸線分別在那裡。
Rca同軸 ohm數唔同
Rca傳analog
同軸傳digital

可否用條更好 power cord 解決？ 本帖最後由 vm8833 於 2015-10-11 17:33 編輯

See wiki，RCA refer to connector and can be used in many applications. S/PDIF-formatted digital coaxial is one of it. Other people already states the difference between analogue and digital application.

Uses
RCA sockets, or jacks, here used for YPbPr video output.
Composite video cable for the Xbox 360.
In the most normal use, cables have a standard plug on each end, consisting of a central male connector, surrounded by a ring. The ring is often segmented for flexibility. Devices mount the socket (female jack), consisting of a central hole with a ring of metal around it. The ring is slightly smaller in diameter and longer than the ring on the plug, allowing the plug's ring to fit tightly over it. The jack has a small area between the outer and inner rings which is filled with an insulator, typically plastic (very early versions, or those made for use as RF connectors used ceramic).
As with many other connectors, the RCA has been adopted for other uses than originally intended, including as a power connector, an RF connector, and occasionally as a connector for loudspeaker cables. Its use as a connector for composite video signals is extremely common, but provides poor impedance matching. RCA connectors and cable are also commonly used to carry S/PDIF-formatted digital audio, with plugs colored orange to differentiate them from other typical connections.
埋叫你講，不是叫你轉貼，你理解RCA與同軸係兩樣野
