Migumisiro Inogona Kukushamisa Iwe
Nhare dzehurukuro uye maitiro avo pamutinhimira inogona kunge iri nyaya yakakavhiringidza iyo inowedzera mukukurukurirana nguva nenguva. Apo paaitaura mukurukuri kadhi miedzo kuAllan Devantier, maneja weacoustic tsvakurudzo paHarman International (vaiti veHarman Kardon vanogamuchira , JBL neInfinity speakers , nemamwe mabhii akawanda ehurukuro), takapinda muhurukuro yakadzika. Zvingave zvichibvira kuratidzira kubva pane unyanzvi hwekugadzira - -kuda mumamiriro ezvinhu zvakanyanyisa - nhare dzekutaura dzinogona kuita kusiyana kwekuona mumanzwi ehurongwa hwako?
Zvimwe Nyaya Yenyaya
Chokutanga, kusazvidzivirira: hatine pfungwa yakasimba pamusoro pematareji anotaura. Takaita mapofu epofu (kumagazini yeThe Home Theater ) umo mapanepanhau akavandudza mafungiro ezvimwe zvematafura pamusoro pevamwe. Asi isu hatiwanzozvifungisisa nezvayo.
Vamwe vanhu vanogona kunzwa vanetseka nemativi ose maviri ehurukuro cable argument. Iko kune mabhuku anoramba achimanikidzira kuti mharidzo dzesimbi hadziiti mutsauko. Uye kune rumwe rutivi, unogona kuwana mamwe mavhesi akareba-ekupedzisira evanotaurira mazwi, mavara, maitiro ezvakasiyana-siyana mu "inzwi" rehurukuro dzetauriri. Zvinoratidzika kune vakawanda kuti mativi ose ari kudziviriridza nzvimbo dzakadzika panzvimbo pekuita mubasa rakatendeseka, rakasununguka kutsvaka chokwadi.
Zvichida kana iwe uri kushamisika, hezvino izvo zvatinoshandisa isu pachedu: dzimwe nhepfenyuro dzep pro dzinowanikwa neCanare, imwe inowanikwa mukati-rusvingo 14-gauge, zvigaro zvechina-conductor zvakarega kumhanya, uye zvimwe zvishoma zvese zvisingagadziri zvakagara zvakakomberedza.
Tinofanira kuwedzera kuti mumakore anopfuura makumi maviri ehurukuro yekuongorora, uye kuedza vatauriri vanobva pasi pe US $ 50 kusvika kune $ 20,000 pahuviri, isu tati tamboita kuti mumwe mugadziri ataure kuti ane hanya nezvezvinhu zvipi zviri kushandiswa.
Allan's Analysis
Chii chakawana Devantier chaive nechido apo patakatanga kutaura pamusoro pekuti mutauri wekambani angagona sei, muchirevo, shandura mhinduro dzenguva yehurukuro.
Mutauri wega wega anonyanya kushandiswa kwemagetsi-kusanganiswa kwekudzivirira, kukwanisa, uye kukwanisa kutarisa (tariro imwechete) kuti inunure unhu hwakanakisisa huri nani. Kana iwe uwedzera kuwedzera kumanikidzika , kukwana , kana kukanganisa , unoshandura hutsika hwehutano uye, nokudaro, inzwi rehurukuro.
Mukana wekutaura mutambo kabhadha hauna kukoshesa kukwana kana kukwanisa. Asi kupikisa kunosiyana-siyana, kunyanya nematare. Nokuti nezvimwe zvinhu zvose zvakaenzana; iyo yakaonda foni, iyo yakanyanya kupikisa.
Devantier akaenderera mberi nekukurukura nekutsvaga tsvakurudzo kubva kuna Floyd Toole uye Sean Olive, vashandi pamwe chete paHarman, avo vaiva panguva iyo vachishanda kuCanada National Research Council:
"Muna 1986 Floyd Toole naSean Olive vakabudisa tsvakurudzo pamusoro pekunzwika kwezvinyaradzo.Vakawana kuti vateereri vanonyanya kugadzikana neA-Q [high-bandwidth] resonances.Midrange peaks ye 0.3 decibels (dB) yakanzwika pasi pemamiriro ezvinhu akakodzera. Sezvo izwi rokumanikidza imhedheni richisiyana nehuwandu hwemashoko, dhigirii ye DC inotakura zvakanyanya. 4 ohms uye hurukuro yakanyanya kutaura ye 40 ohms uye kuti kupikisa kambo ndiyo chete chinhu; hazvirevi kutora uye kukwanisa, izvo zvinogona kuita kuti zvinhu zvisanyanya kuitika. "
"Inofanira kuve yakajeka kubva patafura iyi kuti mune mamwe mamiriro acho tambo uye hurukuro inopikisa inogona kuwirirana kukonzera kunzwisisika resonance."

Brent's Measurements
"Iwe unoziva, iwe unogona kuenzanisa izvi," Allan akati, achitaura munwe wake munzira iyo yaireva murairo kupfuura chirevo.
Tanga tichiita nguva yakawanda mhinduro mhinduro kune vatauri kubva muna 1997, asi tagara tichishandisa yakanaka, huru, mafuta hurukuro cables kuti isunganidze mukurukuri pasi pekuedzwa kune-amp-chimwe chinhu chisingasviki kukarurama kwechiyero.
Asi zvakadini kana tikatsiva mutsara, zvishoma zvishoma zvichitaura hurukuro cable? Chingave chinogona kuenzaniswa here? Uye ingadai ichange iine kusiyana kwerudzi urwo rwaizoteererawo here?
Kuti tione, takayera kutarisa kwemazwi eRevel F208 musheti wekukurukura achishandisa Clio 10 FW audio analyzer nematafura matatu akasiyana-siyana:
- iyo Linn cable ye-12 yakave yakashandiswa kwekutaura zvidzidzo kwemakore mashanu apfuura kana zvakadaro
- iri shoma 12-gauge yaMonoprice cable
- 24-gauge RCA cable
Kuti kuderedze ruzha rwezvakatipoteredza, zviyero zvakaitwa mukati. Hazvinawo maikorofoni kana mukurukuri kana chimwe chinhu chiri muimba yacho chakasimudzirwa. Takashandisa kambo yakawedzerwa yakareba FireWire kuitira kuti kombiyuta nevanhu vose vangave vari kunze kwekamuri. Takadzokorora zvakare muedzo wega wega kazhinji kuti tive nechokwadi chokuti ruzha rwezvakatipoteredza haruna kunyatsobata maitiro. Sei uchichenjerera? Nokuti taiziva kuti taizove tichienzanisa kusiyana kwezvinhu zvisinganzwisisiki - kana chero chinhu chingagona kuyerwa zvachose.
Takazotora mhinduro ne Linn cable uye takaiparadzanisa nemhinduro yematare eMonoprice neRCA. Izvi zvakaguma mune girafu rairatidza kusiyana kwemajairo emagumisiro anokonzerwa nemhando imwe neimwe. Isu takabva tashandisa 1/3-octave kushandura kubatsira kuti tisava nehupfumi hwenharaunda yakasvibira.
Icho chinoitika kuti Devantier akanga akarurama - tinogona kuyera izvi. Sezvaunogona kuona mu chati, zvigumisiro nematafura maviri-gauge zvaingova zvakasiyana zvakasiyana. Shanduko huru yakange iri kukura kwepamusoro +0.4 dB pakati pe 4.3 uye 6.8 kHz.
Izvi zvinonzwika here? Zvichida. Ungada here? Zvichida kwete. Kuti uzviise nenzira yakajeka, iyo inenge 20 kusvika ku30 muzana yemushanduko inowanzoenzaniswa patakaongorora mutauriri uye uye pasina grille .
Asi kushandura kumatare 24-gauge kwakagadzirisa zvikuru. Nokuti kutanga, yakaderedza huwandu, hunoda normalizing yehutano hwemhinduro yekuenzanisa nekuikuridzira +2.04 dB saka inogona kuenzaniswa neyeri kubva ku Linn cable. I-24-gauge yekambani yekupikisa yakavewo nemigumisiro yakajeka pamusana pemhinduro. Semuenzaniso, iyo inodha mabhasi pakati pe50 ne 230 Hz nepamusoro pe--1.5 dB pa 95 Hz, pakati pe2,5 uye 4.7 kHz nechepamusoro pe--1.7 dB pa 3.1 kHz, uye kuderedzwa kunoputika pakati pe6 ne20 kHz nepamusoro -1.4 dB pa13.3 kHz.
Izvi zvinonzwika here? Hongu. Ungada here? Hongu. Ungada here kutinhira kuri nani nekanyoro yakanyora kana imwe yemafuta? Hatizivi. Pasinei nokuti, shanduro yepamusoro ye stereo yakagadziriswa yekushandisa tambo 12-kana 14-gauge iri kutarisa zvakanaka.
Uyu muenzaniso wakanaka kwazvo. Nepo pangave pane zvishomanana zvisinganzwisisiki zvakasimba -kudzivisa hurukuro cables kunze uko, inenge dzose dzeseti dzesimbi dze-14-gauge kana kuti dzakadzika-zvakakwana kushorwa kuti chero sonic anomalies inotanga kuve inofanira kunge isina kudarika (uye zvichida inaudible). Asi zvakakosha kucherechedza kuti takayera zvishoma uye zvakadzokorora kushandiswa kwemashoko, kunyange nemataipi maviri akavhara muhukuru uye sarudzo. Uyewo, cherechedza kuti Revel F208 hurukuro ine mhedziso yepamusoro ye 5 ohms (yakaenzana). Izvi zvinenge zvichinyanya kuzivikanwa ne 4-ohm mutauri uye zvishoma zvichitaurirwa ne 8-ohm speakers, izvo zvinowanzosiyana nemarudzi.
Saka chii chidzidzo chokubvisa pane izvi? Kunyanya, usashandise makanda akacheka mune chero sarudzo iyo iwe une hanya nehuhu hunhu . Uyewo, zvichida usakurumidza kutonga avo vanoti vanoti vanopesana pakati pevatauri tambo. Ichokwadi, vazhinji vavo vari kuwedzeredza zviitiko izvi - uye zvizivo kubva kumagetsi ekukwirira makambani kazhinji zvinowedzera kuwedzeredza izvi. Asi kuverenga uye kuedza kwakaitwa zvinoratidza kuti vanhu vari kunyatsonzwa mutsauko pakati pematare .
