Muri uku kwezi, nzaba ntwaye ibirometero bike munsi ya Ford odometer nsuzuma ingaruka zibicuruzwa bya Ron Sutherland biheruka gutwarwa nubu: $ 3.800 transimpedance dynamic preamplifier yitwa SUTZ.Mu nzira, nzasubira kandi kuri $ 1250 Dynavector DV-20X2 ya karitsiye ya dinamike maze ndebe icyaba cyiza mumurongo wa karitsiye ya Dynavector: $ 2150 XX-2 MKII.
Hanyuma, nzajya nduhuka, mve mu modoka, kandi nzongera kumenyana na Lounge Audio ya $ 355 ya Copla preamp, nkaba ndayakoresheje nshishikaye kuva nasubiramo muri Gashyantare 2018, ariko sinigeze nandika kuva nayisuzuma.
Sutherland Engineering SUTZ namaze umwanya munini ngerageza kwiyumvisha urusaku rwa electromagnetique yose iterwa no kuzunguruka inkoni ihujwe na coil runaka mumashanyarazi.Natekereje ku byuma byanditseho ibiti biva mu rushinge ruto / cantilever / coil, kurambura insinga ya tension no kunyeganyeza coil binyuze mumirongo ihamye yingufu zakozwe na rukuruzi ntoya cyane.Mugihe ibishishwa byanyuze mumashanyarazi ya rukuruzi, umuyoboro uterwa n'uburebure bwazo.
Nize gushushanya igice cyamategeko ya Faraday mumashuri abanza.Mu mashuri yisumbuye, umwarimu yasobanuye amategeko ya Lenz, ndetse bikaba byari bigoye kubyumva: “Uburinganire bw’umubyigano uterwa n’imihindagurikire y’amazi ya magneti butera umuyoboro w’umuriro wa magneti utandukanye n’impinduka yabuteye.”
Igitangaje ni uko amategeko ya Lenz no kwanga magnetique byaje mu bwenge bwanjye mugihe nagerageje kwiyumvisha uburyo ibyiciro byamajwi bigenzurwa byakora nimpamvu byagira ingaruka kumajwi ya cassette murubu buryo.Uku kwibuka kwatumye ntanga igitekerezo ko gupakira amakarito yimodoka hamwe numuzunguruko mugufi (nta voltage yinjiza) byongera umuvuduko unyura mumashanyarazi ya karitsiye, ari nako bigabanya amategeko ya Lenz gusubira inyuma, bityo bikagabanuka kugirango bigere kumurongo munini ushoboka wa cantilever coil (akajambo k'epfo 1).
Hanyuma nagerageje kwiyumvisha uburyo iyi damping iriho yagereranwa na damping yatanzwe na gakondo ya shunt irwanya imbere ya stade ikora.Nahoraga ntekereza ko itandukaniro ryose mumitwaro / damping bigira ingaruka kuburyo stylus ikurikirana neza ibice byanditse, kandi naje gufata umwanzuro ko itandukaniro ryo gusiba (ibyo aribyo byose) bifite inshingano zo gutandukana mugukurikirana, guswera. urusaku, visceral umva Impamvu zirambuye no kugoreka intermodulation.
Kugeza ubu, nashize ahabona ibyiciro bya fono byapimwe, ibyiciro bitandukanye byo guhinduranya intambwe, hamwe na fonctionnement eshatu "transimpedance": Copla ya Lounge Audio ya $ 355, icyiciro cya fono ya Dynavector ya P75 MK3 kumadorari 895, hamwe na Little Loco ya Sutherland Engineering. $ 3.800.
Mu mateka, uburyohe bwanjye mugukina fonografiya bwatonesheje impinduka nini-nikel yo hejuru igerageza kurenza ikirere hamwe na filime ya RIAA tube EQs.Mperuka, nubwo, nagiye nkurikirana amakuru yo murwego rwo hasi, rwinshi cyane kuva muri Sutherland Engineering Ntoya ya Loko igenzurwa na fono ibyiciro nakoresheje hamwe na My Sonic Lab yohereza umusaruro muke (0.3mV), impedance nke (0 .6 ohm) Ultra Ikomeye EX dinamike.Loco ntoya isa niyongera buri kantu kose iyi cartridge itanga.Ugereranije nijwi rya Eminent EX kuri stage kuri Parasound Halo JC 3+ ya fono, combo yanjye My Sonic-Loco yakinnye nini (ukurikije ishusho n'umwanya w'amajwi) kandi yoroshye (ukurikije imiterere nubunini) - hamwe ikuzimu inyuma.Izi ni inyandiko zicecetse.
Mu buryo butunguranye rero ndumiwe: nigute nabona guceceka kwumuzunguruko mugufi hamwe na microdata idafite ingano ntiriwe mpatirwa kureka CinemaScope na tekinoroji ya RIAA?
Nasobanuriye iki kibazo inshuti yanjye Chad Stelly, wazanye ikibazo inshuti yacu dusanzwe Ron Sutherland wo muri Sutherland Engineering (akajambo k'epfo 2);Ron yahise asubiza ati: “Nabikemuye!”Icyumweru kimwe, ninjiye.Ron aherutse kuvumbura, "SUTZ" transimpedance preamplifier, kugeza kuri 47 kΩ yimuka ya magnet yinjiza ya Tavish Design Adagio all-tube phono icyiciro.
Ijambo rya SUTZ riva muri Sutherland Engineering rikoresha chassis imwe ya 17 x 2 x 13 ″ kimwe na Lokoro Ntoya nasobanuye muri Mutarama 2022.Mubyukuri, SUTZ isa neza na Loko nto imbere no hanze.kimwe kimwe gisimbuka-gikora inyungu igenamiterere nka Ntoya.Mbajije inyungu SUTZ ifite, Ron anyandikira ko SUTZs zose zizaza zifite ibice bitanu byunguka, ariko aransebya.Transimpedance amplifier nta "nyungu" kuko ibice byinjiza (amps) bidahuye nibisohoka (volt).“(Akajambo k'epfo 3)
Mbere yuko ntangira, nkwiye kuvuga ko itsinda ryibigize nkoresha aribyo nise sisitemu ya tube yose "real-fi": cartridge ya fono na transformateur-intambwe ihujwe na 10.5 ″ ukuboko kwa Thomas.Schick Dr.Muri iri genzura, nahoraga nibutswa uburyo nakunze iyi sisitemu nuburyo yanditse hamwe nijwi ryuzuye kandi byafashwe amajwi kuruta sisitemu zose nubatse kuva natangira kwandika kuri Stereophile.
Dynavector DV-20X2 Kuva nabisubiramo muri Gramophone Inzozi # 10, nta cassette yo mucyumba cyanjye yakinnye disiki nyinshi kurenza $ 1,250 Dynavector DV-20X2.Njye namaze amasaha amagana ayikinisha byibuze icumi.Irakina uburyo nkunda amakarito ahindagurika: guhina, kwihuta, no gushishoza.Afite mojo-vivo ihagije kugirango akore amajwi afite ingufu hamwe na transfert zikarishye, byose mugihe aruhutse rwose.Kuri iki giciro, amakarito make arashobora gukora byombi.Abantu benshi ntibashobora.
Ndetse nigihe cyose cyakoreshejwe, 20X2 iracyafite imbaraga zo gukora ibishoboka byose kugirango itange umuziki uturika ariko utuje, usubizemo ubudahemuka imwe muma majwi meza kandi azwi cyane yakozwe na injeniyeri w’umurima David Lewiston: Golden Rain LP “Ketjak: Ramayana Monkey Chant” (LP Nonesuch Explorer).H72028).Inzibacyuho zikomeye z'abihayimana 200 baririmbaga icyarimwe ziratangaje, nubwo nari nzi ko zigiye guturika gutaka kwa 'tak'.Abihayimana mu gikari batunganijwe mu ruziga, ibyo bikaba byumvikana iyo urebye.Mu bice bituje, ijisho ryanjye rikunda kwerekana aho abihayimana ku giti cyabo baririmba ku mpera zuru ruziga.Igihe abamonaki bahagarika gusakuza, ijwi ry’ibidukikije mu gikari ryatumye mbona kandi numva bahari.Cartridges hamwe nuru rwego rwubushishozi ntibisanzwe kururu rwego.
