1. Selelekela
U ka bona "Optical" kapa "Digital Audio Out" ka morao ho TV ea hau, soundbar, kapa AV receiver ebe u nahana hore ke ntho e 'ngoe feela. Empa ho tseba seo thapo ya optical e se etsang e ka u pholosa ho tsoa ho li-audio tse khopisang, li-ground-loop hum, le hlooho e opang e tsamaisanang-haholo-holo ha o kopanya lipontšo tsa sejoale-joale le lisebelisoa tsa audio tsa lefa kapa ho tsamaisa molumo o se nang lerata lits'ebetsong tse rarahaneng tsa theater.
Mohala oa optical, oo hangata o bitsoang TOSLINK (Toshiba Link) kapa thapo ea digital optical, e fetisa molumo joalo ka maqhubu a khanya ea infrared ho fapana le mats'oao a motlakase. Phetoho ena e bonolo e tlosa hoo e batlang e le tšitiso eohle, e boloka phihlelo ea hau ea ho mamela e hloekile, 'me e fetela ka nģ'ane ho molumo oa boemo ba bareki ho li-interconnecting tsa data-center, ho fana ka "maele ea ho qetela" le lisebelisoa tse nepahetseng tsa indasteri.
Sengoliloeng sena se hlahloba:
● Ke thapo efe ea optical le hore na e tsoa hokae
