Ukusebenza komsindo

Ekuboneni kokuqala, ukulinganiselwa kokukhipha amandla okushiwo yi-T748 kungase kubonakale kuthobekile, kodwa, empeleni, akunjalo. Izilinganiso zamandla we-T748 zihambisana nesilinganiso se-FTC esilondoloze kakhulu kunamazinga asetshenziswa abakhiqizi abaningi. Ngithole ukuthi ukukhishwa kwamandla we-T748 kungaphezu kokwanele ukugcwalisa igumbi lesayizi elijwayelekile futhi kuqhathaniswa kahle nomamukeli wami wasekhaya wase-Onkyo TX-SR705 kokubili izindlela zokusebenza zesiteshi ezimbili no-5/7.

Ukusebenzisa imithombo yomsindo ye-analog neyedijithali, i-T748, kokubili kokuhlelwa kwesiteshi sesiteshi esingu-5.1, no-7.1, inikeze isithombe esihle esiseduze. I-T748 inamandla, futhi isebenza ngokupholile, ngezikhathi eziningi zokulalela. Ukondla izimpawu zombili ze-PCM zesiteshi ezimbili namanethiwekhi nge-HDMI kusuka ku-OPPO BDP-93, kanye nezinkulumo ze-Dolby / DTS ezingenakulinganiswa nge-HDMI ne-Digital Optical / Coaxial ukuxhuma ukuqhathanisa phakathi kwezimpawu zomsindo zangaphandle kanye nokusetshenzwa komsindo kwangaphakathi kwe-T748, Ngangijabulile ngomphumela. Ukusebenzisa izinto ezihlukahlukene zomculo nomthombo we-movie, i-T748 yenza umsebenzi omuhle kakhulu. Kubekho ukuqonda kwanoma yikuphi ukucindezeleka noma izinkinga zesikhathi sokuvuselela nomculo odinga noma amathrekhi we-movie.

Ngaphandle kwezindlela ezijwayelekile ze-Surround Sound processing, i-NAD iphinde inikeze inketho yayo yokucubungula umsindo: I-EARS (i-Ehanced Ambience Retrieval System) iyindlela ehlukile ku-Dolby Pro Logic II / IIx ne-DTS Neo: 6.

Esikhundleni sokuzama ukuphindaphinda ukuqondisa okuqondile kwezinketho zomsindo ozwakalayo we-Dolby no-DTS, i-EARS ithatha izinkomba zokumangalisa ezitholakala kumarekhodi womculo wesiteshi amabili kanye nezindawo kuphela lezo zindawo ezizungezile eziteshini ezungezile. Lokhu kuklanyelwe ukwakha umsindo ozwakalayo wemvelo, ngaphandle kokuxhashazwa okuqondisayo. Umphumela uba empeleni ngempela.

Ngithole lapho ngiphenya ngezinyathelo ezizungezile ezitholakalayo, i-EARS yenza umsebenzi omkhulu wokugcina ukugxila okuyinhloko ngakwesokunxele, isikhungo, nezikhulumi zesiteshi esifanele, kodwa futhi nokuthumela okwanele kwendawo yokuzungezile futhi nokuthumela amabhasi amancane kuya i-subwoofer, ngaphandle kokwedlulisa ngokweqile kunoma yikuphi. I-EARS ayikwazi ukusetshenziswa ngokuhlanganyela nemithombo ye-Dolby noma ye-DTS, ingcono kakhulu isetshenziswe ngokuqukethwe komculo we-stereo.

Futhi, uma ufisa ukungasebenzisi noma yikuphi okukhethwa kukho okukhethwa kukho umsindo, i-NAD iphinde inikeze isilungiselelo se-Analog Bypass evumela indlela eqondile evela kusignali yomsindo engenayo ngqo kuma-amplifiers nezikhulumi ngokucubungula okuqhubekayo.

I-T748 iphinde inikeze izinketho eziningi zokuhlela umsindo, njengokukwazi ukulungisa izilungiselelo zohlu oluguqukayo lwezinto ezivela kumthombo we-Dolby Digital no-DTS ngokuzimela, kanye nokusetha ku-presets eziyisihlanu ze-A / V ezingabelwa emithonjeni ngayinye ngokuzimela njengento ezenzakalelayo I-A / V ibeka iphrofayili yalo mthombo. Kodwa-ke, ngaphezu kokunikezela ngokuqondile iphrofayli yokubeka i-AV yomthombo ngamunye, ungafinyelela wonke ama-presets atholakalayo emthonjeni ngamunye kanye nokucindezela inkinobho ehleliwe ekude bese ukhetha izinkinobho zenombolo 1 kuya ku-5.

Kodwa-ke, njengoba ngithanda ukuguqulelwa komsindo we-NAD, ngadumala ukuthi izinketho ezimbili zokuxhumana okubalulekile azifakiwe. I-NAD inqume ukuthi ingabandakanyi ukufakelwa kwephono okuzinikezele, noma isethi 5.1 / 7.1 izilinganiso eziningi zesiteshi somzila we-T748.
