Awu, nyaka ngamnye uba ngakumbi nangakumbi ukuba abanini iikhompyutha yegama elithi "ukukhetha ikhadi lesandi" kakhulu nto, "bathi." Kwaye bonke ngenxa yokuba abantu babe nto ukuthelekisa, abaninzi kangaka uyaneliswa zezo zinto esinazo, maxa wambi bade bacinga ukuba kunokuba ngenye indlela. Umzekelo, ukuba ukhangela kwiiforam kwi ukhetho ngamagosa okubeka esweni iimviwo LCD, kumasebe amaninzi kunye kuxoxwe nzulu malunga iingenelo neengozi matrix ethile. Ngokuqhelekileyo, "amngxolise" lo TN mali, yathelekiswa ne-VA, IPS kunye nezinye nezakhi zayo. Oku kungenxa yokuba abantu babe into ukuthelekisa. Kodwa ikhadi lesandi lokudlala umculo kunzima kakhulu ngakumbi, kuba nkqu imodeli elula obubobu ebenokudlula iimpawu ezininzi-yokwenza eyakhelwe ngokusekelwe codecs umsindo HD umsindo AC97. Ngenxa yoko, kukho imeko ngamazwi apho akunakwenzeka ukuba ukhethe kancinane kakhulu okanye ngcono kancinci. Isibini eminyaka eyadlulayo, ukukhetha ikhadi lesandi babengamazi njengoko ukuze kubonakale kulula. Ngoko ke, kwafuneka ukujamelana nawo, umzekelo, thenga wokwenene 16-bit Sound Blaster ukusuka Creative okanye umsinga evela Aureal ukuxhasa bethembisa isandi technology akuyo. Ngoku, kakhulu itshintshe - kukho abavelisi ezintsha, abanye wanyamalala okanye ulibale ngabanye, amakhadi bafumana amathuba ababengaphambi zabo 'ongazange wasicinga. "
Ukukhetha le ikhadi lesandi iqala kunye nokukhethwa zojongano (abazazisayo imifuziselo ekhethekileyo). Uninzi lwabo - ngokuthe ngcembe zisuswe imveliso PCI, omtsha PCI-Express, i USB yangaphandle Ucingo lomlilo. esingcono iya kuba umfuziselo kunye PCI-Express ukuba PC. Le bandwidth le bhasi kwanele ukuba naziphi imilambo odiyo. Kodwa nokukhethwa ikhadi lesandi lwangaphandle umdla, kuqala kwiinto zonke, abanini laptops. Nangona USB ubhetyebhetye ngaphezu Ucingo lomlilo, oko kunokwenza ukulibaziseka, ngoko ukuba uceba ukwenza nzulu emculweni, usebenzisa iselula ikhompyutha, ukhetho mncinane - kuphela IE-1394 (Ucingo lomlilo elinye igama).
Ukukhetha le ikhadi lesandi wambi ayenza isekelwe ubunzulu besuntswana Converter isandi-digital (ADC) - ixabiso lingaphezulu, ngcono. Ngokubanzi, indlela ichanekile. Kodwa khumbula ukuba ngamanye amaxesha umgangatho isandi banazo ezinye iinketho.
Kunqweneleka kakhulu ukuxhasa usulelo ndlela-mbini (dulpex elipheleleyo), apho ungakwazi alobe kanye ukudlalwa ngaxeshanye. Sifanele sinikele ingqalelo oku xa ukhetha ikhadi kunye neenguqulelo ujongano USB omdala (1.1).
I parameter ebalulekileyo elandelayo - inani amagalelo / iimveliso. Thina stereo amakhadi abo ngaphantsi kunolo analog multi-channel. Bonke bephela zahlulwe iindidi ezimbini - twatsa kunye yezi zinto. Ngesiqhelo, oku kubonisiwe imigaqo yobugcisa. I lokuqala ngaphantsi iphenjelelwa ukuphazamiseka ezahlukeneyo.
Digital ovelisa SPDIF - i "ikhadi ubiza" ye sixhobo. It ikuvumela ukuba adlulisele audio oqhelekileyo uwuse kwi kuso nasiphi na esinye isixhobo ngaphandle Bill. Ezibonakalayo isinxibelelanisi SPDIF engafani: Fibre (optic) kunye "eTulip" Classic. Umahluko kuphela ukosuleleka medium, ngoko xa ukhetha imfuneko ingqalelo izixhobo, nto leyo iya kuqhagamshelwa ikhadi lesandi.
Ngokuba iimvumi, iyavakala ukujonga neendlela yobungcali qualitative, kuba kokulibazisa, ingxolo kunye nezinye "ngamakhubalo" yezigqibo lwabiwo nilenze yonke imizamo. Kodwa abasebenzisi ikhaya efuna ukufumana esimnandi, imifuziselo efanelekileyo ezahlukene ze yee-emarikeni evela Asus okanye Creative.
