NAD Viso HP-50 Kawirikawiri Yankho

Apa ndi momwe ndinayeza ntchito ya Viso HP-50. Ndagwiritsa ntchito GRAS 43AG khutu / masaya simulator, analyzer ya Clio 10 FW, kompyuta yotchedwa TrueRTA yolemba kompyuta lapakompyuta ndi M-Audio MobilePre USB mawonekedwe a ma audio, ndi Musical Fidelity V-Can kumutu wamakono. Ndinayesa ndondomeko ya mapulogalamu a khutu (ERP), pafupi ndi malo omwe mutambasula pakhomo lanu pakhomo lanu lakumvetsera pamene mutseketsa dzanja lanu kumbali yanu - komanso momwe nkhope ya HP-50 ikuwombera mungakhale pansi pamene muvala. Ndinasuntha makutu pamutu / tsaya simulator kuti ndipeze malo omwe amapereka yankho yabwino kwambiri komanso zotsatira zake zonse.

Mndandanda pamwambapa ukuwonetsa machitidwe ambiri a HP-50 kumanzere (buluu) ndi kumanja (ofiira) njira. Kuyeza kumeneku kunatengedwa pa mlingo woyesedwa wa 94 dB @ 500 Hz, monga momwe tikulimbikitsira muyeso ya IEC 60268-7. Sitikugwirizana ponena za zomwe "zabwino" zowonongeka pamasewero, koma tchatichi chimakulolani kuti mukhale ndi maganizo enieni a momwe HP-50 ikuyendera.

Yankho la HP-50 likuwoneka ngati laling'ono poyerekeza ndi ma headphone ambiri omwe ndayesera , ndizowonjezera komanso zozama kwambiri pakuyenda pakati pa 2 kHz ndi 8 kHz. Kusiyanitsa kwapansi pazitsulo ziwirizi mwina chifukwa cha kusiyana kwa khutu / tsaya simulator; Zonsezi zimayimira njira yabwino kwambiri yomwe ndinayankhira kuchokera kumsewu uliwonse.

Kuzindikira kwa HP-50, kuyesedwa ndi chizindikiro cha 1 mW chowerengedwa kuti chiwerengero cha 32 ohm impedance ndi cha 300 Hz kufika 3 kHz, ndi 106.3 dB.

NAD Viso HP-50 vs. PSB M4U 1

Tchatichi pano chikuwonetsa machitidwe ambiri a HP-50 (buluu) poyerekeza ndi PSB M4U 1 (green trace), yomwe inanenedwa ndi Paul Barton. Monga momwe mukuonera, miyesoyi ndi yofanana, ndi HP-50 yokhala ndi mphamvu pang'ono pokhapokha 1 kHz ndi mphamvu zina zozungulira 2 kHz.

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

Mafupipafupi a HP-50, njira yoyenera, podyetsedwa ndi amphamvu (Musical Fidelity V-Can) ndi 5 ohms output impedance (red trace), ndi 75 ohms output impedance (green trace). Momwemonso, mizere iyenera kuchitika bwino - monga momwe imachitira pano - zomwe zikusonyeza kuti khalidwe la HP-50 la tonal silidzasintha ngati mutayigwirizanitsa ndi amplifier yamtundu wotsika, monga omwe ali pa laptops ambiri ndi mafoni otsika mtengo.

NAD Viso HP-50 Kutayika kwa Maonekedwe

Cholinga cha mapulaneti otchedwa HP-50, njira yoyenera. Mizere yayitali ya buluu imasonyeza kuwonetserana, komwe kawirikawiri sikuyenera. Chojambulachi chikuwonetseratu kwambiri (ndipo mwinamwake kokha pang'ono ngati kamvekedwe) ma resonances pa 1.8 kHz ndi 3.5 kHz.

NAD Viso HP-50 Kupotoza

Kusiyana kwa harmonic (THD) ya HP-50, kanjira yolondola, yoyezedwa pamsingo woyesedwa ndi kusewera phokoso la pinki pamsinkhu wa 100 dBA. M'munsimu mzerewu uli pa tchati, ndi bwino. Momwemo zikanakhalira pansi malire a tchati. Kusokonezeka kwa HP-50 ndi kotsika kwambiri, pakati pa zabwino zomwe ndaziyeza.

NAD Viso HP-50 Impedance

Kusagwirizana kwa HP-50, njira yoyenera. Kawirikawiri, mpweya wosasinthasintha (mwachitsanzo, wokhazikika) pafupipafupi ndi bwino. Impedance ya HP-50 ndi yozama, yopanga 37 ohms.

NAD Viso HP-50 Kutenga

Kutulutsidwa kwa Viso HP-50, njira yoyenera. Misewu yomwe ili pansipa 75 dB imasonyeza kuchepetsedwa kwa phokoso lakunja - mwachitsanzo, 65 dB pamatanthawuzo amatanthawuza kuchepetsa -10 dB kumvekedwe kwakunja pafupipafupi. Pansi mzera uli pa tchati, ndi bwino. Kudzipatula kwa HP-50 kumakhala kosavuta kumvetsera pamutu, kumachepetsa phokoso kunja kwa -15 dB pa 1 kHz komanso ndi -40 dB pa 8 kHz. Zindikirani kuti palibe kuchepa kwakukulu pafupipafupi 200 Hz, kotero HP-50 sichidzachita zambiri pofuna kutulutsa phokoso la injini ya jet.
