同軸數碼線、訊號線 的分別

請問同軸數碼線、訊號線(紅白線)有咩分別?

大家都係用RCA頭~

但一個110Ω 一個75Ω~

請問係咩黎?

Update:

咁如果用同軸數碼線代替訊號線(紅白線)會點?

    同軸數碼線-是把cd/dvd的digital signal transfer to 一個獨立的digital to analog conveter,以便有更好的音色!110Ω是balabce type,75Ω是unbalance type.

    訊號線(紅白線)-是transfer analog signal,洌如cd to amp,pre-amp to power anp

    如果用同軸數碼線(75Ω)代替訊號線(紅白線),一般是沒有影响的(can transfer analog signal also),只是音色可能不同(as diffrent struture cable have diffrent sound effect).同軸數碼線的structre是一蕊一綱and 75Ω(unbalance)for standard110Ω 同軸數碼線(balance)不是用rca頭,而是用canon頭( ,-,ground接點)
