DAC e nang le headphone amplifier iFi NEO iDSD
iFi NEO iDSD ke motsoako oa molumo, ka kutloisiso e felletseng ea lentsoe. Thepa ea molumo e kopanya DAC, preamplifier le e leka-lekaneng ea li-headphone amplifier, le monyetla oa ho fetisetsa data e se nang mohala. Ena ke sesebelisoa se nang le lintho tse pholileng haholo tsa elektronike, tse se nang mefuta eohle ea lintho ho ntlafatsa molumo le li-filters. Baenjiniere ba k'hamphani ha baa ka ba boloka letho mona. Sephetho ke ts'ebetso e se nang sekoli ka ntle ho lebokose.
iFi NEO iDSD DAC le Amplifier - Overview, Features
Sesebelisoa se ithorisa ka 16-core XMOS microcontroller e amohelang lintlha tse tsoang ho USB le S/PDIF. Ho fapana le lisebelisoa tse fetileng tsa k'hamphani, e sebelisa chip e nang le lebelo la oache habeli le makhetlo a mane a ho hopola. Ho felisa jitter, ho kentsoe GMT femto-clock, e sebetsang hammoho le buffer ea memori e bohlale. Chip ea DSD1793 e tsoang Burr-Brown e ikarabella bakeng sa molumo.
NEO iDSD e ipapisitse le potoloho ea "PureWave" e ts'oanang e sebetsang ka har'a mono o le mong o nang le litselana tse khutšoane tsa mats'oao ho fihlela mohala o ikhethang le bohloeki ba sonic ha o ntse o tlosa crosstalk. Amplifier ea mantlha ea ts'ebetso ke tloaelo ea OV2637A. Taolo ea molumo e etsoa ke potoloho ea discrete ea analog. E laoloang ke taolo ea microprocessor, ho fumana ho nepahala ho phahameng.
Sephetho sa li-headphone se sebelisoa ho sebelisoa transistor ea OV4627A J-Fet le W990VSI attenuator. Hore ho phaella ho boleng bo phahameng ho fana ka boemo bo tlaase ba lerata le ho sotha. E, sena se etsahala ka lisebelisoa tsa molumo tse phahameng, 'me iFi NEO iDSD e hlakile ka har'a batho ba phahameng. Sethala sa amplifier ea li-headphone se ka fana ka matla a fetang 1000mW a tsoang ho 32 ohms.
Qualcomm QCC5100 Bluetooth chipset e tsoetseng pele e tšehetsa li-codec tsohle tsa sejoale-joale tsa audio. Ho feta moo, e fetisa molumo oa boleng bo holimo, ho fihlela ho 24bit / 96kHz. Ho nolofatsa taolo, sesebelisoa se na le "remote control" le pontšo ea OLED e ka pele. Ka tsela, sesebelisoa se ka kenngoa ka holimo kapa ka holimo. Kahoo, ponts'o e its'etleha ka tsela e iketsang ho ea boemong bo khethiloeng. Ts'ebetsong e ntle haholo.
