Oppo Digital PM-1 Ukuphendula ngokuphindaphindiweyo
Ndalinganisa ukusebenza kwe-Oppo Digital PM-1 ngendlela endilinganisela ngayo i-headphone ye-earphone, usebenzisa i-GRAS 43AG indlebe / itekisi simulator, umhlalutyi we-Clio FW, i-computer ephathekayo ene-TrueRTA software kunye ne-M-Audio MobilePre ye-USB isikhombisi-ndlela, kunye ne-Musical Fidelity V-Ingaba i-headphone amplifier. Ndiyilinganisa imilinganiselo yendawo yokubhekisela kwindlebe (ERP), malunga nendawo kwindawo apho intendelezo yakho inqumla ngayo i-axis ye-earal ear when you press the hand against your ear. Akukho mbuyekezo ye-EQ-okt, i-diffuse-field EQ - yaqeshwa. Zonke iimilinganiselo zenziwe kunye nezixhobo zesikhumba ezenziwe ngefestile.
Ishati ekhankanywe ngasentla ibonisa impendulo yempendulo ye-PM-1 ngakwesobunxele (iibhakabhaka) nakwesokudla (iibomvu), kunye nezinga lokuhlola elibhekiselelwe kuma-94 dB @ 500 Hz. Akukho mgangatho wento ethi "ukulungiswa" kwempendulo kwi-headphone, kodwa lo mlinganiso ukhombisa ukungahambi kwendlebe. Uninzi lwee-headphone zineempendulo eziphakamileyo kwi-3 kHz okanye kunjalo (oko kucatshulwa ukuba kwenziwe isandi sekhonophone njengalezi zithethi egumbini langempela), kwaye le nto yenza, kodwa i-3 kHz incopho yayo ithathaka ngo-+6 dB ( Uninzi lwabo lufana no -12 dB). Kunomnye umnene, kwaye uncinci kakhulu, uphazamise kwi-8.8 kHz.
Ukuqonda ubuchule be-PM-1, obulinganiselwe phakathi kwe-300 Hz kunye ne-3 kHz kunye ne-1 mW isalathisi esibalwe kwi-32 ohms impedance i-101.6 dB, ephakamileyo ephezulu kwi-headphone magnetic.
Ukuba unayo nayiphi na imibono okanye imibuzo malunga nale mi miselo, nceda uyifake kwiblogi yasekuqaleni ibhekise kule nqaku.

Oppo Digital PM-1 vs Audeze LCD-X vs HiFiMan HE-6
Le tstshana ibonisa impendulo yesiganeko esilungileyo seentloko ezintathu eziphezulu eziphambili ze-headphone: i-Oppo Digital PM-1 (ulandelelwano oluhlaza okwesibhakabhaka), i-Audeze LCD-X (umkhondo obomvu) kunye neHiFiMan HE-6 (ulandelelwano oluhlaza). Yonke imilinganiselo emithathu ifanele ifile iplani phakathi kwe-50 Hz ne-1.5 kHz. Ngaphezulu, i-PM-1 iyahlula ngokuhlukileyo phakathi kwe-LCD-X kunye ne-HE-6, ebonisa ukuba ingaba yintloko yekhonsompophi engenamdla kule ndawo.

Oppo Digital PM-1 Ukuphindaphinda kwamaxesha, 5 ngokumalunga neminyaka engama-75
Oku kubonisa iimpendulo ezivakalayo ze-PM-1 kwisiteshi esifanelekileyo xa sondliwa ngqo kwi-Musical Fidelity V-Can-5-ohm impedance yomkhiqizo (umbala obomvu), kunye noxinzelelo lwama-ohms angama-70 wongezwa ukudala i-oh ohm 75 i-impedance yemveliso (eluhlaza ulandelelwano). Umphumo ogqityiweyo apha uza kuba yimigca emibini eyahlukana ngokupheleleyo, eya kubonisa ukuba ibhalansi ye-tonal ye-PM-1 ayitshintshi xa utshintsha iifayile zendalo. Kwaye njengoko ubona apha, umphumo we-PM-1 kulo mvavanyo ukhangelelene kakhulu.

I-Oppo ye-Digital PM-1 I-Distectral Decay
Ukubola okubonakalayo (intsalela yamanzi) isicwangciso se-PM-1, isiteshi esifanelekileyo. Imibala eluhlaza okomhlaza / eluhlaza okwakubomvu kubonisa ukuhlawulela, okuqhelekanga okungafunekiyo. Le fowuni ingabonakali ziboniso eziphawulekayo. (Ewe, ubona ukubola kwexesha elide, kodwa oko kuyinto evamile.) Qaphela ukuba isatiyibrari yangaphambili ndiyibonakalise ukubola okude kuyo yonke ibhanki yomsindo; kwisilinganiselo sokuqala ndicinga ukuba ndilibale ukubeka izinto ezidityanisiweyo kwi-PM-1 evulekile, ebendidla ngokuyenza nge-headphones evulekile ukuze isandi sabo singabuyi kubuyiselwa ebhabheni lam.

I-Oppo Digital PM-1 Ukuphambana kunye nokuphindaphinda kwi-100 dBA
I-distortion epheleleyo ye-Harmoni (THD) ye-PM-1, isiteshini esisele, esilinganiswe kumgangatho wokuvavanya we-100 dBA (ulandelelwano lwe-orange) kunye ne-90 dBA (ulandelelwano oluhlaza). Oko ufuna ukukubona apha umgca ohamba phantsi kakhulu kwitshathi. I-PM-1 ayinakho ukuphazamiseka okukufutshane kweso sihloko se-Audeze, kodwa i-PM-1 ibonisa ukuphazamiseka kuphela kwibhande elincinci eliphakathi kwe-220 ne-300 Hz, ephakama ukuya kuma-6 ekhulwini kwi-100 DBA kunye ne-2 pesenti kwi 90 dBA.
Ndibone ukuhlaziya kunye nokucamngca malunga nale milinganiselo kwiifom ye-intanethi, kwaye ndifuna ukugxininisa izinto ezimbalwa eziyimfuneko ukuqonda le milinganiselo - leyo, njengamanani amaninzi e-acoustical, kulula ukuyichaza ngokucacileyo.
Okokuqala, i-100 dBA yinqanaba eliphezulu lokuphulaphula. Ndiyakhetha loo nqanaba lokuvavanya kungekhona kuba libala lokuphulaphula ngokwenene, kodwa kuba lizinga elithile i-headphones inokuvelisa ngaphandle kokuphazamiseka kwaye abanye abakwazi. Ndandisebenzisa ukulinganisa zonke iifowuni kumanqanaba aphantsi kodwa ndafumanisa ukuba kumazinga avakalayo okuphulaphula, ukuphazamiseka akuzange kubekho nakweyiphi na iqondo eliphambili.
Okwesibini, xa ndikwazi ukulinganisa i-headphone ezininzi kwaye ndiyithelekise iziphumo zendlela yokulinganisa ekuziphatheni kwamapolisa aphulaphuleyo, ndafunda ukuba zininzi kwaye ziphi iintlobo zokuphazamiseka ezazivakalayo. Kwimilinganiselo yam (i-headphone 174 ukuya kutsho), ndifumene ukuba abaphulaphuli babika ukuphazamiseka kwendlebe kwiimeko ezigqithiseleyo kuphela, njengee-headphones ezenyukela kuma-10 ekhulwini okanye kwi-THD ephezulu.
Okwesithathu, sisesekwinqanaba lokuqala lokuqonda imilinganiselo yokuphazamiseka kwezicatshulwa zomsindo. Ndicinga ukuba le shishini lenze ngokufanelekileyo kakuhle ne- CEA-2010 ye-subwoofer ephumayo / imilinganiselo yokuphambukisa , kodwa ngaphandle koko, imilinganiselo yokuphambukisa ye-transducers yomsindo ayifanekiyo. Sizenza nge-headphones kuba kulula ukuhlukanisa abaguquleli kwimiphumo yengxolo yendalo; kunye nezithethi, eziza kufuna i-anechoic. Kodwa ngenxa yokuba senza imilinganiselo ayithethi ukuba sinokuqonda ngokupheleleyo iimpembelelo zabo.
Okwesine, ndiyazi abantu abaninzi abenza imilinganiselo yekhanda, kwaye bonke abo ndibaziyo banqwenela ukufumana izigqibo ezithile kwiimilinganiselo zabo. (Njengoko bonke abantu basebenzisa isayensi kufuneka babe.) Isilinganiselo somnxeba sisengumntwana; sinamathela kwimigangatho engapheliyo kwaye engaphelelanga, ngoko ke zonke iingcali zinyanzeliswa ukuba zilandele isigwebo sakhe kunye nezenzo ezifanelekileyo, kwaye zilungelelanise ubuchule bakhe kwisiphi na izixhobo zokusebenza. Ngoko ukuba awuzange wenze umlinganiselo wephonephone ebomini bakho kwaye udweba zonke iintlobo zezigqibo ezithile, ezithembekileyo ezivela kwisethi yemilinganiselo ye-headphones, utyhila ulwazi lwakho nobugcisa.

Oppo Digital PM-1 Impedance
Ubungakanani bemfudu (umkhondo omnyama omgca) kunye nesigaba (ukukhanya okuluhlaza okomhlaza) we-PM-1, isiteshi esifanelekileyo. Kungcono ukuba zombini le mijelo ibonakala njengeplani njengoko kunokwenzeka ngenxa yokuba impedance epholileyo kuzo zonke iifrikansi ngokuqhelekileyo ikunika impendulo engaguquguqukanga xa utshintshe izixhobo zendalo. Kwaye, ngokuqinisekileyo, i-PM-1 ihamba njenge-headphones ifumaneka, nge-impedance ye-32 ohms (efanayo nokulinganisa) kuyo yonke ibhanki yomsindo, kunye nokuguquka kwesigaba esingenanto.

Oppo Digital PM-1 Isolation
Nantsi indawo ebuthakathaka yecomputer evulekile. Ishati apha ibonisa ukuhlukaniswa kwesitishi sokunene se-PM-1, oko kukuthi, ukukwazi ukukhusela isandi sangaphandle. Amanqanaba angaphantsi kwe-75 dB abonisa ukunyanzelwa kwengxolo engaphandle - okt, i-65 dB kwitshathi kuthetha ukunciphisa -10 dB kwizandi ezingaphandle kweso sandi. Umgca wezantsi usetshati, ngcono. Ukutsala kwe-PM-1 kunencinci kunomlinganiselo wesicatshulwa se-magnetic plan back-back, nangona kunjalo, akukho phantse ukuhlala kwiindawo eziphantsi kwe-3 kHz.
