Oppo Digital PM-1 Frequency Response
Ndakayera kushanda kweAppo Digital PM-1 nenzira yandinoyera imwe huru-ear headphones, ndichishandisa GRAS 43AG nzeve / cheek simulator, Clio FW audio analyzer, TrueRTA software yekombiyuta ye laptop paine M-Audio MobilePre USB audio interface, uye Musical Kuvimbika V-Can headphone amplifier. Ndakatarisa zviyero zvenzeve yekucherechedza nzeve (ERP), inenge iyo inzvimbo iyo nzvimbo yako yemichindwe inoputirana ne-axis yenzwi rako rekunzwa kana iwe uchisimudza ruoko rwako kurwisana nenzeve yako. Hapana mubhadharo weEQ - kureva, nzvimbo yakasiyana-siyana EQ - yakashandiswa. Zvose zviyero zvakagadzirwa nehutachiona hwehutu hwakagadzirwa.
Icho chinyorwa chiri pamusoro chinoratidza mhinduro yepamusoro ye PM-1 kuruboshwe (buluu) uye kurudyi (tsvuku) mitsara, ine nhamba yekuedzwa yakatarwa kusvika 94 dB @ 500 Hz. Hapana chirevo chezvakaitwa "zvakanaka" nguva zhinji mhinduro mumusoro, asi chiyero ichi chinoratidza kusanzwisisana kwezwi. Mazhinji headphones ane mhinduro yepamusoro pa 3 kHz kana zvakadaro (iyo inofungidzirwa kuti inzwi rwenhepfoni rakaita seyanoti vatauri muimba chaiye), uye ichi ichi, asi iyo 3 kHz peak isinganyatsonaka paine +6 dB (a Mugove wavo wakafanana ne12 + BD). Kune imwe imwe munyoro, uye yakanyanyisa, yakakwirira pane 8.8 kHz.
Kunzwa kweMDC-1, yakaenzana pakati pe 300 Hz ne3 kHz ne 1 mW chiratidzo chakatarwa kuti yakarongwa 32 ohms impedance is 101.6 dB, iyo yakakosha zvikuru ye planar magnetic headphone.
Kana iwe uine mhinduro kana mibvunzo pamusoro pezviyero izvi, tapota uzviise pabhuku rekutanga rinotaura nezvechinyorwa ichi.

Oppo Digital PM-1 vs. Audeze LCD-X vs. HiFiMan HE-6
Ichi chati chinoratidza nzira yakarurama-kanhiyo yepamhinduro yevatatu vekupedzisira-planar magnetic headphones: Oppo Digital PM-1 (bluu trace), Audeze LCD-X (tsvuku tsvuku) uye HiFiMan HE-6 (ruvara rwekutsvaga). Zvose zviyero zvitatu zvakafa zvakapetwa pakati pe50 Hz uye 1.5 kHz. Pamusoro pazvo, PM-1 inoparadzanisa musiyano pakati peLCD-X uye HE-6, iyo inoratidza kuti inogona kunge iri yakanyanya kutinhira-soro inopikisa muboka iri.

Oppo Digital PM-1 Kushandura Kwemavara, 5 vs. 75 Ohms Zvitubu
Izvi zvinoratidza mhinduro yepamusoro ye PM-1 mumugwagwa wakarurama apo inodyiswa zvakananga neMusical Fidelity V-Can amp 5-ohm output impedance (tsvuku tsvuku), uye 70 ohms kusimba yakawedzerwa kugadzira 75 ohms total output impedance (green tsvaga). Chigumisiro chakanaka pano chichange chiri mitsetse miviri inopera zvakakwana, iyo inogona kuratidza kuti PM-1's tonal balance haigadziri paunoshandura mafaira ekushandisa. Uye sezvaunogona kuona pano, mhinduro yeP-PM pane iyi muedzo yakanaka pedyo nekukwana.

Oppo Digital PM-1 Kuparara Kwemavara
Kuora kwemawere (waterfall) chirongwa che PM-1, chiteshi chakanaka. Yakareba bhuruu / ruvara rwemasvikiro rinoratidza zvinononoka, izvo zvinowanzosadikanwa. Ikosepuru iyi haina kuratidza resonances anocherechedza. (Hungu, iwe unoona kuora kwenguva refu mumabhasi, asi izvozvo zvinowanzoitika.) Cherechedza kuti chati chokutanga chandakatumira chakaratidzira kuparara kwenguva refu mukati mezwi rose remhanzi; pane chiyero chepakutanga ndinofunga kuti ndakakanganwa kuisa zvinhu zvidhori pamusoro pe PM-1 yakasununguka kumashure, izvo zvandinowanzoita nemashurefoni akazaruka kuitira kuti ruzha rwavo rurege kudzoka mubasa rangu.

Oppo Digital PM-1 Kuparadzaniswa vs. Frequency pa100 dBA
Kushandiswa kwehutachiona huse (THD) we PM-1, yakasara, yakayerwa pamwero wekuyera we 100 dBA (marcelline trace) uye 90 dBA (verte trace). Zvamunoda kuona pano ndeyendaneti inotsika zvakanyanya pane chati. I-PM-1 haina kusvibiswa kwepedyo-zero inowanikwa mumusoro weAudeze, asi PM-1 inoratidzira kukanganisa chete mubato rakanyatsopenya pakati pe 220 ne300 Hz, richikwira kusvika kuma6% pa100 dBA uye 2 pfumbamwe pa 90 dBA.
Ndakaona mamwe magwaro uye mafungiro pamusoro peizvi kuenzanisa paIndaneti, uye ndinoda kusimbisa zvinhu zvishoma izvo zvakakosha kunzwisisa chirongwa ichi-icho, kufanana nezvakawanda zvisinganzwisisiki, zvakajeka kusanzwisisa zvisiri izvo.
Chokutanga, 100 dBA inzwi rakanyanya kuteerera. Ndinosarudza iyo sezinga rangu rekuedza kwete nokuti inonyatsoteerera nhamba, asi nekuti iyo imwe iyo mamwe mafoni anokwanisa kubereka asina kukanganisa uye vamwe haagoni. Ndaiwanzoyera mutsara wega wega pamatunhu akaderera asi ndakaona kuti pakunzwa kwemazuva ose, kukanganisa kwakange kusiripo kune chero ipi zvayo yakakura.
Chechipiri, pandakanga ndichikwanisa kuenzanisa misoro yakasiyana-siyana uye kuenzanisa nemigumisiro yechiyero kune maonero ekuzviisa pasi kwevateereri vepanzwi rekuti ndakashandisa, ndakadzidza kuti zvakadini uye zvipi zvekusavhiringidza zvaive nyore nyore kuzvinzwa. Muzviyero zvangu (174 headphones kusvika nhasi), ndakaona kuti vateereri vanotaura kupesana kwekunzwa mumatambudziko akawandisa, akadai se headphones anokwira kusvika ku10 muzana kana akareba THD mumabhasi.
Chechitatu, isu tichiri muchikwata chepakutanga chekunzwisisa kwekusavhiringidza kwezviyero zvevatori vemapurisa. Ndinofunga kuti mhizha iyi yaita zvakanaka kwazvo neEECA-2010 subwoofer yakabuda / kukanganisa zviyero , asi zvisingaiti, kukanganiswa kwezviyero zvevatoriki vemazwi hazviwanzoitwa. Tinozviita ne headphones nokuti zviri nyore kuparadzanisa vatengesi kubva pamigumisiro yeruzhinji rwezvakatipoteredza; ine vatauri, iyo inoda imba ye anechoic. Asi bedzi nokuti tinoita zviyero hazvirevi kuti tine kunzwisisa kwakakwana kwezvavanoreva.
Chechina, ndinoziva vanhu vazhinji vanoita mitambo yemusoro, uye avo vese vandinoziva vanononoka kutora mhedziso chaiyo kubva pazviyero zvavo. (Sezvo vanhu vose vanoita sayenzi vanofanira kunge vari.) Nyaya yemusoro inenge ichiri mucheche; isu takagadzikana uye tisina kukwana, saka vese vadzidzisi vanomanikidzwa kuti vatevere kutonga kwake uye nzira dzakanakisisa, uye kugadzirisa matanho ake kune ipi zvayo yemichina yaanayo. Saka kana iwe usati wamboita chigadziro chemapurogiramu muhupenyu hwako uye uri kukwevera marudzi ose ehumwe, zvivimbo zvekutenda kubva pane zvakagadzirirwa zvikwereti zvemusoro, iwe uri kufungidzira ruzivo rwako uye unyanzvi.

Oppo Digital PM-1 Imhedheni
Kubata kwekukwirira (tsvina yakajeka yemavara) uye chikamu (chiedza chemavara tsvuku) cheMDC-1, chiteshi chakanaka. Zviri nani kana miviri iyi ichiita sechinhu chakaita sechinhu chakabvira nokuti zvinokonzerwa nemhepo yakadzika pamativi ose zvinowanzokupa mhinduro yakajeka paunoshandura mafaira. Uye zvirokwazvo, PM-1 inenge yakareba seyemusoro-soro inosvika, ine impedance ye 32 ohms (yakafanana neyero) kune iyo yose band audio, uye kusagadzikana kwechikamu chekuchinja.

Oppo Digital PM-1 Isolation
Heino nharaunda isina simba yemafuroni akazaruka. Icho chinyorwa apa chinoratidza kuparadzana kwekambani ye PM-1 yakarurama, kureva, kukwanisa kwayo kubvisa kunze kwezwi. Mazinga ari pasi pe75 dB anoratidza kucheneswa kwekunze kwezwi - kureva, 65 dB pane chati zvinoreva -10 dB kuderedza mumanzwi kunze kune iyo nguva inonzwika. Icho chasi pasi mutsetse chiri pa chati, zviri nani. Kubatana kwe PM-1 kunonyatsonaka kudarika chiyero chekuvhara kwe planar magnetic headphone, kunyange zvakadaro, pane hazvirevi kusungirirwa pazvikamu zviri pasi pe 3 kHz.
