DAC ine mahedhifoni amplifier iFi NEO iDSD
iFi NEO iDSD musanganiswa wekuteerera, mupfungwa izere yeshoko. Mudziyo weaudio unosanganisa DAC, preamplifier uye yakadzikama yemusoro amplifier, ine mukana wekutumira isina waya data. Ichi chishandiso chine inotonhorera kwazvo yemagetsi kuzadza, iyo isina marudzi ese ezvinhu zvekuvandudza ruzha nemasefa. Mainjiniya ekambani haana kuchengetedza pane chero chinhu pano. Mhedzisiro ndeyekuita kusina mhosva kunze kwebhokisi.
iFi NEO iDSD DAC uye Amplifier - Overview, Features
Chishandiso ichi chinozvikudza gumi nematanhatu-yakakosha XMOS microcontroller inogamuchira data kubva ku USB uye S/PDIF zvekupinza. Kusiyana nemidziyo yakapfuura kubva kukambani, inoshandisa chip ine kaviri kumhanya kwewachi uye kana ndangariro. Kuti ubvise jitter, GMT femto-wachi inoiswa, inoshanda pamwe chete neakangwara memory buffer. Iyo DSD16 chip kubva kuBurr-Brown ndiyo inokonzera ruzha.
NEO iDSD yakavakirwa symmetrical "PureWave" dunhu rinoshanda mune mbiri mono ine mapfupi masaini nzira kuti uwane yakasarudzika mutsara uye sonic kuchena, pamwe nekubvisa crosstalk. Iyo huru inoshanda amplifier itsika OV2637A. Volume control inoitwa ne discrete analog resistive circuit. Iyo inodzorwa neiyo microprocessor control, kuti uwane yakanyanya kurongeka.
Musoro wemusoro unobuda unoitwa uchishandisa OV4627A J-Fet transistor uye W990VSI attenuator. Izvo mukuwedzera kune yemhando yepamusoro inopa yakaderera mwero weruzha uye kukanganisa. Ehe, izvi zvinoitika pamichina yepamusoro-yekupedzisira audio, uye iFi NEO iDSD iri pachena mune elite. Iyo yemusoro amplifier nhanho inogona kupa pamusoro pe1000mW yemagetsi ekubuda mu32 ohms.
Iyo yepamusoro Qualcomm QCC5100 Bluetooth chipset inotsigira ese emazuva ano macodecs. Uyezve, inotumira ruzha mumhando yepamusoro, kusvika ku24bit / 96kHz. Kurerutsa kudzora, chishandiso chakashongedzerwa neremote control uye yeOLED kuratidza iri pane yekumberi panhi. Nenzira, chigadziro chinogona kuiswa kune horizontally kana vertically. Saka, iyo ratidziro inotenderera otomatiki kune yakasarudzwa kesi yekutarisa. Kuitwa kwakanaka kwazvo.

Iyo NEO yakatevedzana mhinduro yepakati kubva kumugadziri weBritish iFi, pakati pehunyanzvi PRO akatevedzana uye bhajeti ZEN michina. Mukuita kweNEO iDSD, zvaive zvichikwanisika kupa vanoda mimhanzi nehurongwa hwakaenzana maererano nemhando yemhando uye mutengo. Iko kune chikamu chevashandisi chicharamba chakazvipira kune iFi zvigadzirwa, uye chimwe chikamu chinonzwisisa padanho ripi kukwana mukunzwika kunotanga.
