Manufacturers hais lus tsis tshua indulge lawv cov kiv cua thwmsim. Xws li txawv hauj complexity thiab, thiaj li, nqi. Raws li, lub tuam txhab tsis xav kom raug ntxaum mastering paub cov kev taw qhia. Tab sis lub sij hawm yog tseem ua lag luam los ntawm lub sij hawm thawj qauv, uas yog impressive thiab tsos, thiab nrog kev ua tau zoo. Le caag rau qhov kev siv ntawm ib tug kev txuj lom thiab tsim tej zaum yuav sib txawv, tab sis lub ntsiab lub hom phiaj tseem tib yam - kom tau raws li cov neeg xav tau ntawm cov suab paj nruag. Nyob rau hauv qhov kev txiav txim, lub hais lus system Yamaha NS 6490 yog contradictory kev xav. Nws yog pom tseeb tias lub creators muab yug mus rau ib tug tshwj xeeb nyob rau hauv ntau txoj kev, qhov kev loj hlob, tab sis cov kev xyaum ntawm kev siv tsis yog raws li txaus nyiam li tej lus cog tseg elegant tsos thiab tshaj tawm hais tias cov yam ntxwv.

General ntaub ntawv hais txog cov kab

Model tshwj xeeb tshaj yog tsab uas koom rau acoustics pheej yig, tab sis positioned raws li ib tug tag nrho peb-txoj kev system, nruab nrog cov ntxaij lim dej tsis inductances rau ib co ntim. Raws li cov ntaub ntawv ntawm lub chaw tsim tshuaj paus, qhov no configuration tau siv nyob rau hauv thiaj li yuav txo tau distortion, tab sis nyob rau hauv lub kawg, ua tsaug rau cov kev siv ntawm cov kev txwv, tab sis tus nqi tau poob. Nyob rau hauv ib tes, nws yuav tsis phem, tab sis ntawm qhov tod tes, cov neeg siv yuav tsum tau ntawm nws tus kheej los txhim kho lub qauv Yamaha NS 6490. Finalization nquag tsuas yog siv rau cov ntxaij lim dej, tab sis rukastym audiophiles kuj pom zoo them sai sai mus rwb thaiv tsev. Raws li rau lub suab, lub tswvyim txawv hais txog nws. Muab qhov kuj tsis tshua muaj kev ntseeg nyob rau hauv lub ya, qhov zoo yog heev tolerable.

Thiab nws yog ib tug muab hais tias tej frills tsis muab rau nyob rau hauv lub tsim. Ntxiv mus, kaw ntaus kem pom tau hais nyob rau hauv ib tug yooj yim yam los ntawm pheej yig khoom. Muaj ntau cov tswv ntawm lub cev, los ntawm txoj kev, yuav tau kawm nyob rau hauv lub phab ntsa ntawm lub vaj tse pa chipboard. Txawm li cas los, styling yuav pom nyob rau hauv ib tug txawv sis. Ua ntej ntawm tag nrho cov, nyob rau hauv lub "piano" tsim ntawm pem hauv ntej sab thiab silvery week. Tu siab, lub xeem ncej no kuj ua nyob rau hauv cov nyiaj txiag cov kev xaiv uas pheej yig yas.

tsim nta

Diffusers woofer 20 cm mid-range hais lus feature cellulose uas, nyob rau hauv lem, muaj ib tug polymer txheej. Polymer tsim thiab lub tweeter diaphragm, uas yog muab nrog txee txhua Yamaha NS 6490 Dub. Xyuas tseem nco ntsoov tus ntse zoo ib nrig txog kev pom nov ntawm nqaij tawv acoustics thiab loj loj, uas yog tsuas yog 3 kg. Tej zaum nws yog ib tug zoo lub tswv yim, tab sis lub tiav poob yog tsis zoo tshaj plaws txoj kev - los ntawm kev siv ntawm zoo cov ntaub ntawv uas nyob rau hauv lub vaj tse nyob thiab lub teb tsis tuaj kawm ntawv ntawm lub suab-absorbing insulator. Suab Pib ntsais koj teeb rau kev kho ob emitters ntaus electrolytic capacitor, uas yog sawv cev los ntawm tus txheej txheem cov ntxaij lim dej nrog lub kom muaj nuj nqis ntawm lub caij txom nyem ntawm tus nqes hav ntau ntawm txog 6 dB. Ob leeg systems paired txhua muaj siab lub taub hau npaug offset nyob rau hauv txoj kev ntug ntawm sab vaj huam sib luag, uas siv npaum ntawm cheeb tsam. Tag nrho cov hais lus yog nruab nrog sib nqus cov ntxaij vab tshaus zoo zoo.

Xyuas ntawm lub suab zoo

Interestingly, thawj lub tswv yim ntawm cov feem ntau ntawm cov neeg siv ntawm cov qauv no yog dag ntxias. Thiab qhov no kuj siv rau qhov zoo thiab tsis zoo rau cov kev mloog. Tab sis txawm yog cov khees coj kev siv cov qauv Yamaha NS 6490, xyuas ntawm lub suab nyob rau hauv tag nrho cov zoo. Acoustics qha cov feem ntau crisp, ntshiab thiab sib sib zog nqus ntses bass thaj tsam. Tsis tas li ntawd, cov qauv yog cai kom muaj ib tug zoo momentum thoob plaws hauv lub ntau yam. Zoo cwj pwm txawv ua thiab ua si hard pob zeb nrog nrov songs. acoustics tswv tuab lub suab ntawm uas music, raws li ib tug txhav, kaj thiab lub siab lub ntsws. Qhov no siv tau kuj yuav shock, thiab hluav taws xob guitar.

Tsis li ntawd, straightforward teeb meem no nrog cov classical repertoire.

Feem ntau yog cov menyuamuas ntawm ib tug dynamic pab Yamaha NS 6490 txhua hais tias me ntsis txuag qhov teeb meem no. Nyob rau hauv kev, cov neeg siv tau qhia hais tias nws yog kaj thiab haib acoustics, uas muaj peev xwm txaus los mus sau lub suab ntawm cov chav mus txog 60 m ^2.

acoustic kev kawm

Rau ib tug pib nws muaj nqis ntsoov teev ib tug heev theem siab ntawm rhiab heev, uas muaj peev xwm khav tsis yog txhua qauv nyob rau hauv nws chav kawm ntawv. Qhov no cov yam ntxwv yog 93,5 dB, uas lom zem ntau piav txog cov kev zoo thiab kev ncaj ncees ntses bass thaj tsam ua si hnyav suab paj nruag. Nws zoo nkaus li zoo thiab srednenizkochastotny site - Txawm li cas los, raws li cov kev loj hlob nqi nce, ua uas tsis yog-uniformity yam ntxwv. Tsis tas li ntawd nyob rau hauv lub keeb kwm yav dhau ntawm kev nce ntawm rhiab heev nyob rau hauv lub chav 3000-6000 Hz yuav tshwm sim thiab ib tug nkag siab ntawm brightness playback. Nws yuav tsum tau muab sau tseg tias brightness Yamaha NS 6490 acoustics amenable mus npaum hloov los ntawm kev pauv qhov chaw ntawm txhua. Piv txwv li, lub orientation ntawm ib tug 45-degree angle eliminates lub ntxiv puab flare. Thaum zaus theem ntawm 3000 thiab 5000 Hz cim kev los afterglow. Raws li hais distortion, lub basses yog zoo tsis tuaj kawm ntawv - yam tsawg kawg yog tus mloog tus impedance yog negligible. Qhov no kuj siv rau lwm yam zaus ntau ntau, nyob rau hauv tas li ntawd mus rau lub resonant seem - lawv pab kom paub daws tsuas muaj zoo amplifier.

Finalization ntawm txhua

Txawm tias nws cov qeb hais lus daws zoo nrog lub hom phiaj ntawm tu tub tu kiv, muaj coob tus neeg tsis meej pem heev heev yooj yim acoustic tsim. Raws li kws txawj nco ntsoov, koj yuav ua rau kom cov muaj suab tej zaum los ntawm ib tug yooj yim txawj tej yam ntxiv system Yamaha NS 6490. Finalization lim capacitors txawj tej yam ntxiv yuav tsum tau ua lub suab smoother thiab ruaj khov, thiab cov kev taw qhia ntawm ib tug damping khoom, raws li cov neeg siv, xa cov shortcomings nyob rau hauv lub qis ntau.

Rau realization ntawm txoj kev ua no yuav tsum tau cov purchase ntawm capacitors 400 V rau HF thiab MF cable, uas nws tus ntoo khaub lig seem tej zaum yuav 1.04 hli ^2, thiab cov damping khoom. Raws li, qhov muab xam yuav tsum tau ua li cas rau upgrade cov txhua ob. Tab sis ua ntej embarking rau ib tug kho dua yuav tsum coj mus rau hauv tus account uas cov nyhuv tej zaum yuav chim. Piv txwv li, ntawm cov txhim kho raws li ib tug tshwm sim ntawm renovation thiab muaj ib qho kev nce ntses bass thaj tsam hum tshem tawm rau siab kawg volume ntawm cov nuj nqis ntawm lub damping khoom. Tab sis peb yuav tsum xav thiab tsis kaj siab distortions nyob rau hauv qhov nruab nrab ntau. Yog hais tias qhov no tshwm sim yog zoo siab, ces koj yuav tau pib kom rework AC Yamaha NS 6490. tsev nyob disassembly yog ua li cas feeb - los ntawm dismantling fasteners. Tom ntej no, tshiab ntsiab muab ib tug kev twb kev txuas los ntawm soldering nrog ib tug tin-nyiaj - qhov no siv rau cov lus qhia nyob ntawm tej.
