NAD Viso HP-50 Frequency Response

Heino maitiro andakayera maitiro eViso HP-50. Ndakashandisa GRAS 43AG nzeve / cheek simulator, Clio 10 FW audio analyzer, TrueRTA software yemakombiyuta inotakura laptop neInternet AudioPre USB interface, uye Musical Fidelity V-Can headphone amplifier. Ndakatarisa zviyero zvenzeve yekucherechedza nzeve (ERP), inenge iyo inzvimbo iyo nzvimbo yako yemichindwe inoputirana ne-axis yenzeve yako yekunzwa kana iwe uchisimudzira ruoko rwako kurwisana nenzeve yako-uye pamusoro pokuti chiso chemufambisi weCh-50 chikavhiringidza ungagara apo iwe uchipfeka. Ndakatamisa mapepa emakumbo kumativi ose munzeve / chekisi simulator kuti ndiwane nzvimbo iyo yakapa zvakanakisisa bass response uye yakanakisisa chigumisiro zvachose.

Icho chinyorwa chiri pamusoro chinoratidza mhinduro dzenguva dze HP-50 kuruboshwe (bhuu) uye kurudyi (tsvuku) mitsara. Ichi chiyero chakatorwa pachikwata chekuedzwa chakatarwa kusvika 94 dB @ 500 Hz, sezvakakurudzirwa muIEC 60268-7 mutsetse wepamusoro wekorofoni. Pane zvishoma kubvumirana pamusoro pezvinoti "zvakanaka" nguva zhinji mhinduro mu headphones, asi chati ichi chinokubvumira kuti uwane mafungiro evariro yekuti HP-50 inotarisana sei.

Mhinduro yeCh-50 inoratidzika yakajeka kana ichienzaniswa nemakorikoro akawanda wandakayera , nekanyoro uye yakawandisa kukurudzika pakuderera pakati pe 2 kHz ne8 kHz. Misiyano iri pasi pemisidhari yemiti miviri inogona kunge yakakonzerwa nekusiyana kwakakwana pane nzeve / cheek simulator; zvose zviri zviviri zvinomiririra zvakanakisisa mabhasiro anopindura wandakwanisa kuwana kubva kune imwe kero.

Kuziva kwe HP-50, kuenzaniswa nemushumo wemm 1 wakatarwa kuti yakarongwa 32 ohms impedance uye yakaenzana kubva pa300 Hz kusvika ku3 kHz, ndiyo 106.3 dB.

NAD Viso HP-50 vs. PSB M4U 1

Icho chinyorwa apa chinoratidza mhinduro dzenguva yakawanda dze HP-50 (bhuruu yebhuruu) inofananidzwa ne PSB M4U 1 (tsvaga tsvuku), iyo yakave yakataurwa zvakare naPauro Barton. Sezvaunogona kuona, zviyero zvakafanana chaizvo, ne HP-50 ine simba shoma pasi pe1 kHz uye zvishoma zvishoma simba rinosvika 2 kHz.

NAD Viso HP-50 Mhinduro, 5 vs. 75 Ohms

Frequency respond of the HP-50, channel right, when fed by amp (Musical Fidelity V-Can) ne 5 ohms output impedance (red trace), uye 75 ohms output impedance (green trace). Zvakanaka, mitsara inofanira kuwirirana zvakakwana - sezvavanoita pano - iyo inoratidza kuti HP-50's tonal hupenyu haingachinje kana iwe uchiiunyorera kune yakadzika yemhepo inosimudzira, sezvinowanikwa mumapuraneti akawanda uye emafoni asina mari.

NAD Viso HP-50 Kuparara Kwekuona

Kuora kwezvirwere (waterfall) chirongwa che HP-50, chiteshi chakanaka. Masero mashoma emabhuruu anoratidza zvinononoka, izvo zvinowanzosingadi. Iyi nyorofoni inoratidza zvishoma kwazvo (uye zvichida zvishoma chete kana zvese zvinonzwika) resonances pa 1.8 kHz uye 3.5 kHz.

NAD Viso HP-50 Distortion

Kushandiswa kweHarmic (THD) yeHP-50, kero yakarurama, yakayerwa pachiyero chekuedzwa chinotambidzwa nekupenya rwiyo rwepinki pamusana wevheji 100 dBA. Pasi apa mutsara uri pa chati, zviri nani. Zvichida zvaizoputira muganhu wezasi we chati. Kuparara kwe HP-50 kunonyanya kuderera, pakati pezvakanakisisa zvandakayera.

NAD Viso HP-50 Impedance

Kusagadzikana kwe HP-50, chiteshi chakanaka. Kazhinji, imhedheni isingagumi (kureva, yakadzika) pazvikamu zvose zviri nani. Imhedheni ye HP-50 inenge yakazara, inokwana 37 ohms.

NAD Viso HP-50 Isolation

Isolation yeViso HP-50, gwara rakarurama. 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. Kuparadzaniswa kweHC-50 kwakakosha nokuda kweputikiti yepamusoro-nzeve, kuderedza kunze kwekunzwika -15 dB pa 1 kHz uye ne -40 dB pa8 kHz. Cherechedza kuti hapana kukanganisa kunowanikwa pasi pemaodzanyemba 200 Hz, saka HP-50 haigoni kuita zvakawanda kugura jet injini yekunzwa.
