Kuyambira Edison ndi Berliner mpaka lero. Zaukadaulo za turntable.

Onani Turntables mu sitolo ya Muzyczny.pl

Mu gawo ili la mndandanda wathu, tiwona mbali zaukadaulo za turntable, zinthu zake zofunika kwambiri komanso momwe zimakhudzira phokoso la analogi la ma vinyl record.

Makhalidwe a singano za galamafoni

Kuti singano ikhale bwino mu groove ya mbiri ya vinyl, iyenera kukhala ndi kukula ndi mawonekedwe oyenera. Chifukwa cha mawonekedwe a nsonga ya singano, timawagawa kukhala: ozungulira, elliptical ndi shibaty kapena singano zabwino. Singano zozungulira zimatha ndi tsamba lomwe mbiri yake ili ndi mawonekedwe a gawo la bwalo. Mitundu ya singano iyi imayamikiridwa ndi a DJs chifukwa amamatira bwino ku groove ya mbiriyo. Kuipa kwawo, komabe, ndikuti mawonekedwe a singano amayambitsa kupsinjika kwamakina m'mitsempha, ndipo izi zimatanthawuza kusabereka bwino kwa kudumpha kwakukulu pafupipafupi. Komano, singano za elliptical zimakhala ndi nsonga yooneka ngati ellipse kuti zikhale mozama muzolembazo. Izi zimachepetsa kupsinjika kwamakina ndipo motero kuwononga pang'ono kwa mbale poyambira. Singano za kudula uku zimadziwikanso ndi gulu lalikulu la ma frequency opangidwanso. Shibata ndi singano za mzere wabwino zimakhala ndi mawonekedwe apadera, omwe amapangidwa kuti azigwirizana ndi mawonekedwe a groove ya zolemba. Singano izi zimaperekedwa kwambiri kwa ogwiritsa ntchito kunyumba.

Makhalidwe a cartridge ya phono

Kuchokera pamalingaliro aukadaulo, cholemberacho chimasamutsa kugwedezeka kwazomwe zimatchedwa phono cartridge, zomwe zimasinthanso kukhala ma pulses amagetsi amagetsi. Titha kusiyanitsa mitundu ingapo yodziwika bwino yoyika: piezoelectric, electromagnetic (MM), magnetoelectric (MC). Zida zakale za piezoelectric sizigwiritsidwanso ntchito ndipo zoyika za MM ndi MC zimagwiritsidwa ntchito kwambiri. Mu makatiriji a MM, kugwedezeka kwa cholembera kumasamutsidwa ku maginito omwe amanjenjemera mkati mwa makoyilo. M'makoyilowa, mphamvu yamagetsi yofooka imapangidwa ndi kugwedezeka.

Zoyikapo za MC zimagwira ntchito m'njira yoti ma koyilo azigwedezeka pa maginito osasunthika omwe amayendetsedwa ndi singano. Nthawi zambiri muma amplifiers okhala ndi phono input, titha kupeza masiwichi a MC kupita ku MM, omwe amagwiritsidwa ntchito kugwiritsa ntchito mtundu woyenera wa cartridge. Ma cartridge a MC pokhudzana ndi MM ndi abwino kwambiri pamawu amtundu, koma nthawi yomweyo amafunikira kwambiri pankhani ya phono preamplifier.

Zolephera zamakina

Ziyenera kukumbukiridwa kuti turntable ndi wosewera wamakina ndipo amakumana ndi zolephera zamakina. Kale pakupanga zolemba za vinyl, nyimbo zoimbira zimachitidwa chithandizo chapadera chomwe chimachepetsa nthawi yowonjezereka ya zizindikiro. Popanda chithandizochi, singanoyo sikanakhala ndi kulumpha kwakukulu kwafupipafupi. Zachidziwikire, chilichonse chimayenera kukhala chokhazikika bwino, chifukwa zojambulira zokhala ndi kuponderezedwa kwambiri pakuwongolera sizimveka bwino pa vinyl. Cholembera chomwe chimadula bolodi la amayi chimakhalanso ndi malire ake amakina. Ngati chojambulira chili ndi ma frequency ochulukirapo okhala ndi matalikidwe okwera, sichingagwire bwino pa rekodi ya vinyl. Njira yothetsera vutoli ndi kuwachepetsera pang'ono kudzera mu kusefera pafupipafupi.

Dynamika

Kuthamanga kwa turntable spin kumakhazikika pa 33⅓ kapena 45 revolutions pamphindi. Choncho, liwiro la singano wachibale ndi poyambira zimasiyanasiyana malinga ndi singano pa chiyambi cha mbale pafupi m'mphepete kapena kumapeto kwa mbale pafupi pakati. Pafupi ndi m'mphepete, liwiro ndilokwera kwambiri, pafupifupi mamita 0,5 pamphindi, ndi mamita 0,25 pamphindi pafupi ndi pakati. Pamphepete mwa mbaleyo, singanoyo imasuntha kawiri mofulumira ngati pakati. Popeza kuti mphamvu ndi kuyankha pafupipafupi zimadalira liwiro ili, opanga ma analogi amayika nyimbo zamphamvu kwambiri kumayambiriro kwa chimbalecho, komanso zodekha mpaka kumapeto.

Vinyl bass

Apa zambiri zimatengera dongosolo lomwe tikuchita. Kwa chizindikiro cha mono, singano imangoyenda mopingasa. Pankhani ya chizindikiro cha stereo, singano imayambanso kusuntha molunjika chifukwa ma groove akumanzere ndi kumanja amasiyana mawonekedwe, chifukwa chake singanoyo imakankhidwira m'mwamba ndi kulowa mkati mwa groove. Ngakhale kuphatikizika kwa RIAA kumagwiritsidwa ntchito, ma frequency otsika amapangitsanso kupotoza kwakukulu kwa cholembera.

Kukambitsirana

Monga mukuonera, palibe malire oletsa kujambula nyimbo pa rekodi ya vinyl. Amapangitsa kuti zikhale zofunikira kusintha ndikukonza zinthuzo musanazisunge pa disk yakuda. Mutha kudziwa za kusiyana kwa mawu pomvera chimbale chomwechi pa vinyl ndi pa CD. Njira ya galamafoni imakhala ndi malire ambiri chifukwa cha makina ake. Chodabwitsa n'chakuti, ngakhale zili ndi malire awa, nthawi zambiri nyimbo za vinyl zimakhala zosangalatsa kumvetsera kusiyana ndi zina zomwe zimajambulidwa pa CD. Apa ndipamene matsenga a phokoso la analogi amachokera.
