Final Take

Hannun ƙirar fitowar wutar lantarki na iya zama alamar ladabi a takarda, amma T748 yana bada iko mai yawa fiye da mafi yawan ɗakuna kuma yana ba da sauti mai ban mamaki. Ayyuka masu dacewa da nake son hadawa sun haɗa da: Tsarin saitunan sarrafa bayanai, tsarin saiti na atomatik, sauyawa ta 3D, da fassarar bidiyo na analog-to-HDMI (kodayake ba a bayar da cikakken aikin bidiyo da upscaling) ba.

T748 kuma ya yi babban aiki a duka ɓangaren sitiriyo da cikakken kewaye da sauti. Babu wata alamar nuna ɓatawa ko ɓoyewa a manyan kundin kuma ina tsammanin hada da magoya bayan kwantar da hankali biyu shine babban ra'ayi - injin yana da kyau a kwatanta da yawancin masu karɓa na karɓa.

T748 yana samar da saiti da zaɓuɓɓukan haɗaka, ba tare da yawan fasalulluka da haɗi ba, amma bai ƙunshi wasu zaɓuɓɓuka waɗanda zan sa ran a cikin kimar darajarsa ba, irin su shigarwar phono mai ɗorewa ko bayanan audio na analog na 5.1 / 7.1.

Idan girmamawa akan aikin sauti da sassauci, ba tare da shigarwar phono na al'ada ba don wani sauti mai mahimmanci kuma ba 5.1 ko 7.1 tashoshin analog na analog ba yana da dadi ga mai karɓar mai jihohi a cikin tashar farashin $ 900.
