Simba uye Utera - Chikamu 1

Iyo yaFebruary yemagazini yeAudio yakaburitsa bvunzo yekufananidza yevashanu stereo amplifiers yePLN 20-24 zviuru. zloty. Ivo vanogona kutoverengerwa seyepamusoro-yekupedzisira, kunyangwe iyo pricing framework isiri kudzorwa nemitemo yakasimba. Uye kunyangwe paine anodhura zvakanyanya amplifiers - kunyanya iyo "preamplifier - simba amplifier" musanganiswa, pakati peakabatanidzwa amplifiers iwo akanyanya dhizaini.

Zvakakodzera kuvatarisa zvishoma "mashortcuts". Ndedzipi dzakakosha mhinduro dzinogona kuwanikwa padenga iri? Ndezvipi zvakanakira zvavo pamusoro pemidziyo yakachipa? Dziri dzemazuva ano here, dzinoshanda zvakasiyana-siyana, dzakasimba, dzakasimba kana, pamusoro pezvose, dzakanyanyisa, dzichiunza nemutengo chete mazano ehutano?

An audiophile acharatidzira panguva ino: iyo chaiyo mhando yeamplifier kana chero mudziyo weodhiyo hauyerwe neiyo yakayerwa simba, nhamba yezvigadziko uye mabasa, asi inoongorora nyaya idzi zvichienderana nekurira!

Hatisi kuzopokana nazvo zvachose (zvishoma kwete panguva ino). Tichanzvenga dambudziko rinounzwa nenzira iyi, yatakatenderwa nechinangwa nenzvimbo yechidzidzo chino. Tichatarisa pane yakachena tekinoroji, tichikurukura nyaya dzakawanda.

Digital inputs

Nekukosha kuri kukura kwemasaini edhijitari masosi, akawanda uye akawanda amplifiers ane zvigadzirwa zvemadhijitari, uye nekudaro edhijitari-kune-analog anoshandura. Ngatitsanangure, kana zvikaitika, kuti mupfungwa iyi hatitarise CD player se "digital source", sezvo yakashongedzerwa neD / A converter uye inogona kutumira chiratidzo cheanalog kune amplifier. Saka zviri kunyanya nezvemakomputa, malaptop, maseva, nezvimwewo, patinogara tichichengeta mamwe emaraibhurari emimhanzi yedu kakawanda uye kakawanda. Kushanda kwavo kunogoneka neakasiyana-siyana akagadziridzwa masisitimu, asi panofanira kunge paine D / A inoshandura kumwe kunhu mavari - ingave seyakazvimiririra mudziyo kana sehurongwa hwakavakirwa mune chimwe chishandiso.

Imwe yemhinduro dzinogoneka uye dziri nyore ndeyekuisa DAC mune amplifier, seamplifier inofanirwa kuve iripo mune yega yega odhiyo system, kazhinji zvakare ichiita se "dzimbahwe", inounganidza zvikwangwani kubva kwakasiyana-siyana - saka ngaitorewo dhijitari. zviratidzo. Nekudaro, iyi handiyo yega uye inosunga mhinduro, sezvinoratidzwa nebvunzo iyi (kunyangwe yakanyanyisa uye isingamiriri zvakanyanya kune ese amplifiers). Vanosvika vatatu pavashanu vakaedzwa amplifiers vaive vasina DAC pabhodhi, izvo zvisiri zvinonyadzisa kana chikonzero chekurumbidza. Zvinogona kuguma kwete zvakanyanya kubva ku "kunonoka", asi kubva mumutemo uye kufungidzira kuti muridzi wepamusoro-kirasi system achave achida kutenga yakaparadzana, yakakwana yepamusoro-kirasi DAC, isingagutsikane nedunhu rakavakwa mukati. iyo yakabatanidzwa.

Arcam A49 - inoshanda chete pamasaini eanalogi, asi ndiyo yakanyanya kukwana mune izvi: ine phono yekupinda (MM) uye headphone kubuda.

Ehe, iwe unogona kuzviona zvakasiyana, ndiko kuti, tarisira yakakwira-kirasi amplifier kuti ive yemazuva ano uye yakawanda sezvinobvira. Nekudaro, zvinoenderana nezvido zvemunhu uye pfungwa yehurongwa hwese. Icho chokwadi ndechekuti mune amplifiers kubva kumitengo yakaderera (kunze kweiyo yakachipa), yakavakirwa-mukati madhiraivha anotonyanya kuwanda, saka yekutanga mhedziso pamusoro peanodhura akabatanidzwa amplifiers ndeyekuti mundima iyi havaratidzi pamwe chete mukana wavo. pamusoro pemhando dzakachipa.

Nekudaro, pane zviitiko, uye zvakaitikawo muyedzo yedu, apo amplifier yakanyatsoshongedzerwa, ichishandisa azvino dhijitari maseketi, ayo atisingazosangana nawo (zvichida kwete izvozvi) mumadhizaini akachipa, kunyangwe kutamba chinzvimbo chemutambi werukova. (kunze kwekushandura dhijitari kuita analog, kukwanisawo kuburitsa mafaera, ayo aunoda mamwe marongero). Saka kana isu tichitsvaga yemazuva ano uye "inotonhorera" amplifier, tichaiwana nekukurumidza pamatengo epamusoro, asi ... iwe unofanirwawo kuitsvaga ipapo, kwete kuitora kutanga kubva kubhangi - mutengo wega. hazvivimbisi izvozvo.

Phono-danho

Chimwe chidimbu chakakosha chemidziyo mune yemazuva ano amplifier ndeye turntable yekupinza (ine MM / MC cartridges). Kwemakore akawanda pamiganhu yekufarira, yakawana zvakare kukosha kwayo, hongu, pamhepo yekuvandudzwa kweiyo turntable pachayo.

Rega tikuyeuchidze muchidimbu kuti chiratidzo chinobva kuMM / MC cartridges chine maparamita akasiyana zvachose pane chiratidzo kubva kune icho chinonzi. linear, iyo iyo amplifier "mutsara" inogadziriswa inogadzirirwa. Chiratidzo chakananga kubva kubhodhi (kubva kuMM / MC inopinza) ine yakaderera nhanho uye isiri-mutsara hunhu, inoda kururamiswa kwakakomba uye kuwana kusvika kumiganhu yechiratidzo chemutsara uye inogona kupihwa kune mutsara wekupinda yeamplifier, kana zvakananga kumaseketi ayo ezasi. Mumwe anogona kubvunza kuti sei phono-matanho asina kuvakwa mumaturntable (seD / A anoshandura akavakirwa kuita maCD player), kuitira kuti chiratidzo chemutsara chiyerere chakananga kubva kuturntable? Munguva pfupi yapfuura, mamwe ma turntables ane akavakirwa-mukati kuenzana akaonekwa, asi kwemakore chiyero chave chakasimbiswa kuti mushandisi anofanira kutarisira kururamisa pachake; pamwero waanogona uye ane hanya nawo.

Iwo chaiwo maitiro ekururamisa uye kukwidziridzwa kwechiratidzo chinouya kubva kucartridge kunofanirwa kuenderana neayo paramita, uye izvi hazvina kunyatso kudzorwa nezviyero (zviri mukati memiganhu yakafara). Mazhinji emakaturiji ane maparamendi ari padyo nehunhu hunotsigirwa zvakanaka nemaseketi akakurumbira akaiswa mune akasanganiswa amplifiers (ngatidaidze iyo yakakosha mhinduro). Nekudaro, kuwana mibairo yakanakisa, kunyanya nemakaturiji ekumusoro-soro, inoda zvese zvakanatswa kuenzana zvigadziriso uye yakaringana yemhando yepamusoro dunhu rese. Basa rakadaro rinoitwa neakaparadzana phono nhanho, muchimiro chezvishandiso zvakazvimirira, zvidiki uye zvakakura, kazhinji nekutonga kweakawanda paramita. Nekuda kweiyo pfungwa yekuvaka yakakwira-kirasi sisitimu, umo marekodhi evinyl achaita basa rakakosha, kusiiwa kweMM / MC kururamisa dunhu mune yakasanganiswa amplifier kunonzwisisika, zvakafanana nekushaikwa kweD / A inoshandura dunhu. . Imhaka yekuti munhu haafanire kutarisira - kunyangwe kubva kune yakanakisa yakasanganiswa amplifier - kushanda kweyakanyanya uye yakaomesesa phono-stage. Chingave chinodhura chinhu cheiyo yepamusoro-yekupedzisira dhizaini, isingakodzeri kune ruzhinji rwevashandisi.

Nekudaro, imwe chete yeashanu akaedzwa amplifiers ine inopindurwa yekupinda, uye mune yakanyanya mwero vhezheni, yeMM cartridges. Kutaura zvazviri, kupinza kwakadaro kunokwana 95% yevashandisi vese veanalog, uye zvichida hafu yevashandisi veanalog mumitambo yepamusoro-yepamusoro - anenge munhu wose anoda turntable nhasi, asi vanhu vashomanana vanodzingirira inzwi rayo pamutengo wakakwirira. Zvakadaro, mamiriro akadai (mumwe chete kubva pavashanu) anoodza mwoyo zvishoma. Iyo yakakosha MM kuenzana, kunyangwe kwekutanga kwakanaka kutamba neanalog, yaisazokuvadza chero yakasanganiswa amplifier, isingadhure kana kudhura.

Gato Audio DIA-250S - yemazuva ano, ine chikamu chedhijitari (USB, coaxial uye optical inputs), kunyange nekuwedzera kweBluetooth, asi pasina phono kupinza uye headphone kubuda.

Headphone kubuda

Zvingaite sekunge munguva dzekuzivikanwa kukuru kwemahedhifoni, yakasanganiswa amplifier inofanirwa kuve nekubuda kwakaringana. Uye zvakadaro… mhando mbiri chete dzaive nadzo. Pano, iyo (isina kusimba) kururamisa zvakare ipfungwa yekushandisa yakasarudzika michina, mune iyi kesi mahedhifoni amplifiers, ayo anogona kupa iri nani ruzha mhando pane ine mwero wedunhu rakavakirwa mune yakabatanidzwa amplifier. Nekudaro, vazhinji vashandisi veanodhura zvakanyanya masisitimu, anosanganisira amplifiers uye magudzanzwi, vanobata mahedhifoni seimwe nzira, backup yekuteerera nzira, havashandisi mari yakawanda pavari, uye kunyange zvishoma havadi kushandisa zvakanyanya pane yakakosha mahedhifoni amplifier. ... Vanongoda kubatanidza mahedhifoni avo "kune imwe nzvimbo" mahedhifoni (kwete kubatanidza midziyo inotakurika).

Bluetooth inobva kune imwe paramende yakasiyana zvachose. Imwe yeashanu amplifiers yakashongedzerwawo nayo, uye zvechokwadi ndeimwe yeaya maviri ane chikamu chedhijitari. Muchiitiko ichi, hazvisi zve "kuvhura" kune dzimwe nzvimbo dzemhando yepamusoro-soro, asi nezvemazuva ano munharaunda yekukurukurirana, kunyange zvazvo hutano hwakanyanya kuderedzwa nemiganhu yeBluetooth standard pachayo; Haisi iyo audiophile yekuwedzera, asi haufanire kuishandisa. Uye zvakare - rudzi urwu rwegajeti (kunyangwe ingave ichiyedza uye inobatsira kune vakawanda) inowoneka mune zvakachipa amplifiers. Saka kunyangwe zvichiri kushoma, hakusi kukwezva kwatinofanira kubhadhara pamusoro pePLN zviuru makumi maviri. zloty...

XLR zvigadziko

Ngatitaureiwo nezve XLR mhando sockets (yakaenzana), iyo inopedzisira iri chinhu chemidziyo kazhinji inowanikwa mune anodhura amplifiers pane anochipa. Ese mamodheru mashanu ebvunzo yakataurwa ane XLR yekupinda (zvakare pa "nguva dzose" maRCA), uye matatu zvakare ane XLR yakabuda (kubva muchikamu chepreamplifier). Saka zvinoratidzika kuti kune amplifier ye20 zviuru. PLN ingave chirema, kushaikwa kwezvinhu zvakadaro, kunyangwe kukosha kwavo kunokwanisa kukurukurwa. Mune imwe yeakaedzwa amplifiers iyo XLR sockets chikamu chezvinonzi yakadzikama, ichikubvumidza kuti utumire uye kukwidziridza masaini muchiyero chakazara chedunhu. Mune mamodheru akaedzwa, siginecha inopihwa kune iyo XLR yekupinza inokurumidza desymmetrized uye inofambiswazve nenzira imwechete nemasaini anopihwa kune isina kuenzana RCA mapipu. Saka pane chete mabhenefiti ekufambiswa kwechiratidzo mune yakaenzana fomu (iyo, chokwadi, iwe unodawo sosi mudziyo une XLR inobuda), iyo isinganyanyi kukanganiswa nekukanganiswa kwekunze. Nekudaro, izvi zvine basa rakakosha kana iri yekubatana kwenguva refu uye munzvimbo izere nezvinokonzeresa - nekudaro iri chiyero mu studio tekinoroji, nepo muaudiophile system inoramba iri "fancy". Mukuwedzera, zvinogona kuderedza kunaka, nokuti mamwe madesimmetrization maseketi (chiratidzo mushure mekuisa) anogona kunge ari tsime rekuwedzera ruzha. Chenjerera nekushandiswa kwe XLR mapipu uye usafunge kuti vanozopa mhedzisiro iri nani.

Hegel H360 - yakafara mikana yechikamu chedhijitari (inogashira kwete chete PCM kuburikidza ne USB, asiwo Flac uye WAV mafaera kuburikidza neLAN). Nehurombo, zvakare pano hapana chekupinza cheturntable kana kubuda kwehedhifoni.

Chete mune zvinodhura amplifiers dzimwe nguva tinowana mamwe mabasa, akarongwa mumenyu (pamwe chete neakawanda kana kushoma kuratidzwa), zvichibvumira mushandisi kuseta kunzwisiswa kwemunhu ega ega, azvipe mazita avo, nezvimwe zvakadaro, zvinokwezva zvakadaro hazvina kudikanwa kuti munhu wese afare, uye hazvisi zvechigarire kuva zvinosungirwa kunyangwe pakati pepamusoro-kirasi amplifiers. Nekudaro, muboka rakaedzwa, hapana aive nazvo, kunyangwe mana anga aine zviratidziro, asi kungoratidza ruzivo rwekutanga (chiratidzo cheiyo yakasarudzwa yekupinda, vhoriyamu level, uye mune imwe nyaya zvakare sampling frequency yedhijitari yakapihwa, uye mune imwe nyaya chete chiyero chevhoriyamu, asi nekururama kunoshamisa - kusvika hafu decibel).

Mugamuchiri ari nani?

Kupfupisa iyo inoshanda sphere, iyo yakaedzwa amplifiers seboka haina kufadza nechero chinhu, ichifunga nezvemitengo yavo. Mamwe acho akanyanya kukosha, ayo, zvisinei, akakwana kune akawanda maaudiophiles, angave ari kuvaka "minimalist" sisitimu (semuenzaniso ine CD inoridza uye magudzanzwi chete) kana yakagadzirira kutenga hunyanzvi michina inogadzirirwa kune zvinodiwa nemunhu (DAC, phono). -stage, headphone amplifier). Izvo "zvinoodza mwoyo" zvezvivakwa zvakakurukurwa zvinogona kuwedzerwa kuti nhasi vanogamuchira AV vanogona kuzvirumbidza nemidziyo iri nani - nemidziyo iri muchikamu chinokurukurwa pano, tisingaverenge hupfumi hwekuwedzera hune chekuita nekugadziriswa kwemasaini uye multichannel ruzha. Vese vane mahedhifoni anobuda, ese ane D / A anoshandura (nekuti anofanirwa kunge aine mapipu edhijitari, kusanganisira USB), mazhinji acho ane mapipu edhijitari, iwo akashata chete haana kana iri nyore yekuridza mutambi (LAN yekupinda), uye vazhinji vane zvakare nyore, asi zvakadaro - phono-stage ...

Iyo chokwadi chekuti ese akaedzwa amplifiers anodzorwa kure haifanire kutombotaurwa, nekuti ndicho chinhu chakakosha nhasi.

Yekupedzisira yemhando yekuongorora ichiri yakavhurika. Mukati memwedzi tichakurukura matunhu emukati uye maparameter echikamu chinonyanya kukosha - magetsi amplifiers emhando idzi. Mushure mezvose, sezvinoreva zita, iyo amplifier yakagadzirirwa kukwidziridza ...
