rca in shield

[brunoland]

Zanima me a shield ozemljim na obeh straneh rca ali samo na enem koncu. Gre za sub kabel, èe sploh igra to vlogo.

Ozemlji na enem koncu in potem daj to na izvor. Tudi èe gre za sub in èe mase v vseh napravah niso dobro narejene, lahko dobiš nekaj bruma, èe boš ozemljil na obeh koncih.

Hvala.

Signalni kabel rabi shield enako kot rabi pes garje..
Za ljubitelje filtriranega zvoka, ja, èe živite poleg radijskega pretvornika, tudi.

Pri Tempoelectric zadnjih 20 in veè let razvijajo shielding, baje da ga bodo lansirali kmalu..

Shielding

Audio cables not only conduct the audio signal, itself, but can act as antennas, picking up RFI (Radio Frequency Interference)—mainly AM and short wave radio—and EMI (Electro-Magnetic Interference)—usually a hum or buzz that's caused by a nearby electrical field. The latter can be from an AC transformer, turntable motor, or AC power cable. When listeners refer to"noisy" cables, what they really mean is that the cable is picking-up unwanted noise from an external source. These phenomena are completely local, somewhat unpredictable, and relatively rare.

The only successful technique that can make cables completely immune from RFI and EMI is total shielding with a full copper braid and a shield-to-earth connection. This is the way balanced or XLR cables are constructed. However, if not done properly, direct shielding can also restrict the higher frequencies (>10KHz) which, in turn, reduces air and transparency. We're in the process of developing a shield that avoids this problem and plan to offer it as an option in the near future. Based on personal experience, most audio systems don't require shielded cables (especially in lengths of 2 meters or less), but in some situations they may be a necessity.

Sicer pa lahko vsak sam ugotovi ali je zanj primernejši kabel z shieldom ali brez.
Prvo naredi brez in posluša minimalno en teden.
Nato doda shield in se odloèi, za ali brez..

Potem takem na obeh straneh interkonekta dam shield privijaèit. V redu.
Edit: Bom probal brez in z.

[brunoland]

Sem probal ne da bi shield dal na konektorje in je bil grozen hum! Eno stransko niè bolje, dvo stransko pa sedaj dela brez kakšnega slišnega huma (vsaj na prvi pogled).

Bi bila kako drugaèe, èe bi bil sub kabel brez shielda?

[ro-bi]

Jaz sem mislil shield v kablu, ki ima znotraj dva vodnika za + in - in zunaj oplet. Na takem kablu se oplet prilota samo na eni strani.
Imel sem že nekaj takih interkonektov.
Èe ima kabel samo v centru en vodnik in oplet, potem je normalno, da zlotaš na obeh koncih, saj drugaèe ne dela.
