NAD I-Viso HP-50 Impendulo yokuphindaphinda

Nantsi indlela ndilinganise ngayo ukusebenza kwe-Viso HP-50. Ndasebenzisa i-GRAS 43AG indlebe / itekisi isimulator, i-analyzer yomsindo we-Clio 10 FW, ikhomputha yekhompyutheni esebenzisa isofthiwe ye-TrueRTA nge-interface yomsindo we-M-Audio MobilePre ye-USB kunye ne-Musical Fidelity V-Can. Ndiyilinganisa imilinganiselo yendawo yokubhekisela kwindlebe (ERP), ngokucacileyo kwinqanaba kwindawo apho intendelezo yakho inqumla ngayo i-axis ye-earal ear when you press your hand against your ear-and about where the face of the driver's HP-50. uya kuhlala xa ugqoke. Ndadlulisela iimvalo ngeenxa zonke kwindlebe / itekisi simulator ukufumana isikhundla esinikezela ngokusisiseko isiphumo kunye nesiphumo esiphezulu saso sonke.

Ishati ekhankanywe ngasentla ibonisa impendulo yexesha elide le-HP-50 kwicala lasekhohlo (oluhlaza okwesibhakabhaka) nelungileyo (obomvu). Lo mqathango uthathe kwizinga lokuvavanya elibhekiselelwe ku-94 dB @ 500 Hz, njengoko kunconywe kwi-IEC 60268-7 imilinganiselo yesilinganiselo somlomo. Kukho isivumelwano esincinane malunga nento ethi "ukulungeleka" impendulo kwi-headphones, kodwa le tshathi ikuvumela ukuba ufumene ingcamango yecandelo le-HP-50.

Impendulo ye-HP-50 ibonakala ifuthe xa kuthelekiswa neentloko zee-headphones endilinganiseleyo, ngomoya ovulekileyo kwaye unobanzi ngokubanzi phakathi kwe-2 kHz ne-8 kHz. Umahluko kwimpendulo yeendlela ezimbini mhlawumbi ngenxa yokungafani kakuhle kwindlebe / itekisi simulator; Bobabini bamele i-best bass impendulo endikwazi ukuyifumana kwinqanaba ngalinye.

Ukuqonda ubukhulu be-HP-50, ekulinganiselwe ngumbonakaliso we-1 mW obalwe kwi-32 ohms impedance kunye ne-300 Hz ukuya kwi-3 kHz, ngu-106.3 dB.

NAD Viso HP-50 vs PSB M4U 1

Isatshati apha ibonisa impendulo yempendulo ye-HP-50 (umkhondo wempuphu) ngokuthelekiswa ne-PSB M4U 1 (ulandelelwano oluhlaza), oluye lwachazwa nguPaul Barton. Njengoko ubona, imilinganiselo ifana kakhulu, ne-HP-50 ibe namandla angaphantsi kwe-1 kHz kunye namandla angaphezu kwe-2 kHz.

NAD Viso HP-50 Impendulo, 5 ngokumalunga nama-75

Ukuphendula ngokuphindaphindiweyo kwe-HP-50, isiteshi sokunene, xa sondliwa yi-amp (Umculo Fidelity V-Can) kunye ne-5 ohms impedance yokuphuma (umtsalane obomvu), kunye ne-75 ohms impedance yemveliso (ulandelelwano oluhlaza). Ngokufanelekileyo, imigca kufuneka ifakeke ngokugqibeleleyo-njengoko yenzayo apha-ebonisa ukuba umgca we-HP-50 weetaliti ayiyi kutshintsha xa uxhuma kwi-amplifier yomthombo ophantsi, njengalezo ezininzi kwii-laptops kunye ne-smartphone eziphantsi.

NAD Viso HP-50 UkuLawulwa kweMpawu

Ukubola kwe-spectral (waterfall) isicwangciso se-HP-50, isiteshi esifanelekileyo. Imijelo emide eluhlaza eluhlaza ibonisa ukuhlawulela, okungekho nto engathandekiyo. Le ngqununu ibonisa imincinci (kunye mhlawumbi nje kuphela ukuba iyonke ezwakalayo) i-resonances kwi-1.8 kHz ne-3.5 kHz.

NAD Viso HP-50 Ukuphazamiseka

I-distortion epheleleyo ye-Harmoni (THD) ye-HP-50, isiteshini sokunene, esilinganiswe kumgangatho wokuvavanywa usetyenziswe ngokudlala isandi se-pink kwizinga eliphakathi kwe-100 dBA. Umzantsi lo mgca usetshati, ngcono. Eyona nto yayiza kubakho umda wezantsi wetadi. Ukuphazamiseka kwe-HP-50 kuphantsi kakhulu, phakathi kweyona nto ifanelekileyo.

NAD Viso HP-50 Impedance

Ukunyanzeliswa kwe-HP-50, umzila ochanekileyo. Ngokuqhelekileyo, impedance ehambisanayo (okt, i-flat) kuzo zonke iifrikansi zibhetele. Impedance ye-HP-50 ibingaphantsi, ii-ohm ezingama-37.

I-VAD HP-50 Isolation

Ukukhutshwa kwe-Viso HP-50, umzila ochanekileyo. 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. Ukuhlukaniswa kwe-HP-50 kuvelele kwi-headphone ye-ear-ear, ekunciphiseni izandi zangaphandle -15 dB kwi-1 kHz kunye no -40 dB kwi-8 kHz. Qaphela ukuba akukho nciphiso ebonakalayo kwiimpawu ezingaphantsi kwe-200 Hz, ngoko i-HP-50 ayiyi kuyenza ininzi ekunqumeni ingxolo yenjini ye-jet.
