I-DAC ene-headphone amplifier iFi NEO iDSD
I-iFi NEO iDSD iyinhlanganisela yomsindo, ngomqondo ophelele wegama. Imishini yomsindo ihlanganisa i-DAC, i-preamplifier kanye ne-balanced headphone amplifier, nethuba lokudluliswa kwedatha okungenantambo. Lesi isisetshenziswa esinokugcwalisa okupholile kwe-elekthronikhi, esingenazo zonke izinhlobo zezinto zokuthuthukisa umsindo nezihlungi. Onjiniyela benkampani abazange bonge lutho lapha. Umphumela uwukusebenza okungenasici ngaphandle kwebhokisi.
I-iFi NEO iDSD DAC kanye ne-Amplifier - Uhlolojikelele, Izici
Idivayisi ine-16-core XMOS microcontroller eyamukela idatha esuka ku-USB kanye nokokufaka kwe-S/PDIF. Ngokungafani nemishini yangaphambilini evela enkampanini, isebenzisa i-chip enejubane lewashi eliphindwe kabili kanye nenkumbulo ephindwe kane. Ukuze kuqedwe i-jitter, i-GMT femto-clock ifakiwe, esebenza ngokuhambisana nesigcinalwazi sememori esihlakaniphile. I-chip ye-DSD1793 yaseBurr-Brown inesibopho somsindo.
I-NEO iDSD isuselwe kumjikelezo we-"PureWave" olinganayo osebenza nge-mono embaxambili enezindlela zesignali ezimfushane ukuze kuzuzwe umugqa okhethekile kanye nobumsulwa be-sonic ngenkathi futhi isusa i-crosstalk. I-amplifier eyinhloko yokusebenza i-OV2637A yangokwezifiso. Ukulawulwa kwevolumu kwenziwa yisifunda esiphikisayo se-analog. Okulawulwa yi-microprocessor control, ukuthola ukunemba okuphezulu.
Ukukhishwa kwe-headphone kusetshenziswa i-OV4627A J-Fet transistor kanye ne-W990VSI attenuator. Lokho ngaphezu kwekhwalithi ephezulu kunikeza izinga eliphansi lomsindo nokuhlanekezela. Yebo, lokhu kwenzeka emishinini yomsindo ephezulu, futhi i-iFi NEO iDSD ngokusobala isezingeni eliphezulu. Isiteji se-headphone amplifier singahlinzeka ngaphezu kwe-1000mW yamandla okukhiphayo ku-32 ohms.
I-chipset ye-Qualcomm QCC5100 ye-Bluetooth ethuthukisiwe isekela wonke ama-codec alalelwayo esimanje. Ngaphezu kwalokho, idlulisa umsindo ngekhwalithi ephezulu, kuze kufike ku-24bit / 96kHz. Ukuze kube lula ukulawula, idivayisi ifakwe isilawuli kude nesibonisi se-OLED esibekwe kuphaneli engaphambili. Ngendlela, idivayisi ingafakwa ngokuvundlile noma iqonde. Ngakho-ke, isibonisi siphenduka ngokuzenzakalelayo siye kumacala akhethiwe. Ukuqaliswa kuhle kakhulu.

Uchungechunge lwe-NEO luyisixazululo esimaphakathi esivela kumkhiqizi waseBrithani i-iFi, phakathi kochungechunge lwe-PRO lochwepheshe kanye nesabelomali semishini ye-ZEN. Ekusebenzeni kwe-NEO iDSD, kwakungenzeka ukunikeza abathandi bomculo ngesistimu elinganiselayo ngokwekhwalithi yomsindo kanye nentengo. Lapho ingxenye yabasebenzisi izohlala izinikele kumikhiqizo ye-iFi, futhi enye ingxenye izoqonda ukuthi isiphi isigaba ukuphelela emsindweni kuqala.
