Txhawm rau ua tiav lub suab zoo thaum txhim kho lub kaw lus, koj yuav tsum tau them sai sai rau txhua yam - hais lus, amplifiers thiab, tau kawg, hais lus cable. Koj yuav tsis tuaj yeem tau txais lub suab zoo txawm tias los ntawm lub kaw lus kim yog tias koj siv cov xaim tsis tu ncua. Shielded cable - qhov no yog li cas koj yuav tsum txuas lub teeb liab qhov chaw rau cov playback li. Txwv tsis pub, koj yuav xaus mloog suab nrov ntawm lem.

hais lus cable

Niaj hnub hais lus cable muaj ob lossis ntau dua tus neeg siv hluav taws xob tam sim no, muab tso rau hauv rwb thaiv tsev ua los ntawm PVC, Teflon, polyurethane thiab lwm yam khoom siv polymeric. Cov xov hlau yog cov khoom siv hluav taws xob zoo ib yam, tab sis tau cim nrog cov xim sib txawv kom tus neeg siv tsis sib xyaw polarity thaum sib txuas, sib txuas cov khoom siv.

tooj liab yog cov khoom tseem ceeb. Nws muaj qhov hluav taws xob qis tshaj plaws, uas tso cai rau koj kom ua tiav lub suab zoo. Txawm li cas los xij, thaumcable tso lub sij hawm tuaj yeem dhau ze cov kab hluav taws xob. Vim li no, cov teb sib nqus, eddy tam sim no, yuav inevitably tshwm sim, uas yuav txo tau lub suab zoo.

Txhawm rau zam qhov teeb meem no, siv cov xaim tshwj xeeb - tiv thaiv. Xws li ib tug cable muaj kev tiv thaiv tshwj xeeb ua los ntawm hlau los yog yas, uas yog ib hom "screen" los ntawm electromagnetic cuam tshuam.

Nyob ntawm tus hais lus cables

Yuav kom cov hlau thaiv zoo tib yam los tiv thaiv kev cuam tshuam kev cuam tshuam, nws yuav tsum txuas nrog hauv av, uas yog, hauv av. Qee zaum, qhov kev txiav txim no tsuas yog ua tsis tau. Tias yog vim li cas qhov sib npaug cable tau tsim. Yog hais tias nyob rau hauv ib tug zoo tib yam neeg xyuas pib muaj tsuas yog ib tug central "qhib" uas nqa lub ntsiab teeb liab, ces nyob rau hauv ib tug sib npaug cable muaj ob ntawm lawv - kub thiab txias. Lawv ob leeg nqa tib cov ntaub ntawv, tab sis nrog sib txawv "zoo sib xws". Kev ua tau zoo ntawm cov kab no nyob ntawm qhov sib npaug ntawm cov pas nrig.

Star Quad cables muaj kev tiv thaiv zoo, nyob rau hauv uas ob khub ntawm "rods" yog insulated thiab txuas nyob rau hauv parallel rau ib leeg, uas ua tiav qib siab ntawm kev tiv thaiv. Cov kws tshaj lij kuj paub qhov txawv ntawm qhov hu ua conductive hlau, thaiv nrog yas. Hom kab no siv tau zoo nyob rau hauv luv luv, xws li thaum txhim kho lub suab hauv lub tsheb.

Microphone cables tuaj yeem sib txawv rau hauv ib pab pawg sib txawv, qhov kev tiv thaiv yog ua los ntawm cov khoom siv woven. Tab sis qhov ntau yam thiab muab kev tiv thaiv zoo tshaj plaws yog cov ntawv ci thaiv cov xov hlau.

Cov xov hlau tiv thaiv

Cable nrogfoil tiv thaiv txawv ntawm ib leeg nyob rau hauv cov khoom los ntawm qhov screen yog tsim, raws li zoo raws li hom braid.

shielded tooj liab hlau

Muaj plaub hom kev tiv thaiv hluav taws xob hauv tag nrho:

  • foiled tooj liab lossis txhuas daim thaiv npog - muab kev tiv thaiv zoo ntawm cov neeg siv hluav taws xob los ntawm EMI, tab sis muaj kev cuam tshuam rau kev khoov, tig (kev tiv thaiv tawg thiab tawg);
  • tooj liab mesh braid - hlau thaiv hauv txoj kev no muab kev tiv thaiv zoo tshaj plaws tiv thaiv kev cuam tshuam, tab sis yog kim heev (siv hauv cov cuab yeej tshaj lij);
  • Kauv braid ua los ntawm tooj liab lossis lwm yam hlau uas tsis yog-ferrous - xws li cable yuav luag tsis raug rau cov neeg kho tshuab kev ntxhov siab thiab tiv thaiv kev cuam tshuam zoo.

Hom plaub yog ib lub cable nrog lub vijtsam ua ke, uas sib txuas cov khoom siv tau zoo ntawm cov ntawv ci thiab ntau hom braids. Lawv txawv los ntawm tus nqi nruab nrab, ntau yam khoom loj thiab kev tiv thaiv siab.

tus neeg coj ua haujlwm thiab lub suab zoo

Cov hluav taws xob tiv thaiv ntawm tus neeg xyuas pib muaj kev txiav txim siab ntawm lub suab zoo. Qhov kev tawm tsam ntawm cov kab hais lus nyob ntawm ntau qhov ntsuas - cov khoom siv, thaj chaw hla thiab qhov ntev ntawm cable.

Lub suab zoo tshaj plaws tsuas yog muab los ntawm cov hlau tooj liab thaiv nrog ntawv ci. Nyob rau tib lub sijhawm, tsawg kawg 20 xov hlau yuav tsum nyob hauv qab txheej rwb thaiv tsev. Yog hais tias, txawm li cas los xij, qhov chaw hla ntu tsis tshaj 2.5 hli 2, thiab qhov ntev cableyuav nyob rau hauv 3 meters, ces tus kuj yuav yog xoom. Raws li, lub suab zoo nrog xws li ib tug hlau yuav yog qhov zoo tshaj plaws.

Qhov ntsuas ntawm tus neeg xyuas pib kuj cuam tshuam rau cov khoom siv. Piv txwv li, cov xov hlau ntev muaj ntau qhov capacitance thiab inductance, uas tsim ib qho ntxiv load ntawm lub amplifier.

Kev sib txuas cables

Ib qho kev sib txuas cable yog ib tus neeg xyuas pib tsis tu ncua, nyob rau qhov kawg uas muaj cov ntsaws tshwj xeeb rau kev sib txuas rau cov khoom siv, lossis thaiv. Interconnect shielded cables, xov hlau muaj qee qhov sib txawv ntawm cov kab hais lus zoo tib yam.

Tshwj xeeb, lub suab zoo ntawm no tsis yog nyob ntawm hom kev tiv thaiv, tab sis ntawm cov khoom siv. Koj tuaj yeem txheeb xyuas cov khoom los ntawm kev kos npe:

  • SSs HI END SP - qhov no yog lub npe ntawm cov kab acoustic ua los ntawm cov nyiaj-plated tooj liab, muaj peev xwm tsim tau lub suab zoo tshaj plaws.
  • EMT OFC sc - tus ntawv luv siv los qhia cov xov hlau ua los ntawm cov hlau tsis muaj pa oxygen, qhov zoo ntawm cov teeb liab kis tau zoo yog thib ob rau tus neeg sawv cev dhau los.
  • AHpsc 16 GA - yooj yim cov neeg ua haujlwm zoo.

Yog tias koj tab tom nrhiav cov cables uas tuaj yeem xa cov teeb liab yam tsis muaj kev cuam tshuam, ces koj yuav tsum xyuam xim rau cov ntawv luam uas ua los ntawm cov nyiaj tag nrho. Cov khoom no raug nqi ntau pua daus las rau ib lub 'meter', tab sis cov teeb liab zoo uas lawv kis tsis tau piv tau.

Multicore cables

Ib qho chaw tshwj xeeb hauv kev ua lag luam ntawm cov khoom siv acoustic yog shielded hlautso tseg.

Nyob rau hauv xws li ib tug neeg xyuas pib, nyob rau hauv ib txheej ntawm rwb thaiv tsev, muaj ob peb strands intertwined ib leeg. Lawv muaj ntau qhov zoo ntawm cov tub ntxhais cables:

  1. High elasticity - cov xov hlau tsis ntshai ntawm kinks, tig thiab lwm yam kev ntxhov siab.
  2. poob tam sim no qis - vim lub teeb liab kis tau los ntawm ob peb "rods" ib zaug.
  3. High-zoo hloov - cov txheej txheem tshwm sim hauv thawj vib nas this tom qab luv luv Circuit Court (thaum hloov lub toggle hloov, piv txwv li) tsis muaj txiaj ntsig.
  4. Kev ntseeg siab thiab ua haujlwm ntev - kev pabcuam lub neej ntawm cov khoom zoo li no yog qhov kev txiav txim siab ntau dua li ntawm ib leeg-core.

hom kab no muaj qee qhov tsis zoo. Thawj ntawm lawv yog tus nqi siab. Yog li ntawd, tus nqi rau ib tug shielded ob-core hlau yuav ncav cuag 1500 rudders. Tsis tas li ntawd, cov conductors zoo li no tsis tsim los ua haujlwm hauv kev sib txuas siab.
