Ratidza Mutengo Wakakwana Wemasimba YeNyika Yako
Imwe yezvinonyanya kunyanya kuitika muhurukuro iri kutarisa kuti chii chinokurisa amplifier yako inotaura inoda. Kazhinji, vanhu vanoita sarudzo yakadaro zvichibva pane zvisinganzwisisiki uye dzimwe nguva zvisinganzwisisiki mutauri uye zvigadziridzo zvinogadziriswa . Vakawanda vanowedzera kutevera mafungiro pamusoro pekuti mazamu nevanotaura vanoshanda sei. Takapedza makore tichiedza uye tichiyera vatauri - pamwe takawana shure--mavara mazano kubva pakutaurirana nezviuru zveanjiniya nevanotengesa mumabhizimisi e-audio - saka heino izvo zvaunofanirwa kuziva!
Chokwadi Pamusoro Pekutaura Simba Simba Kuchengeta Mazita
Kutanga, zvakakosha kunzwisisa kuti kutaura kwemasimba kugadzirisa zvido zvinowanzorehwa. Kazhinji, iwe unongoona "simba guru" zvisinganzwisisi nezvekuti sei yakagadzirwa sei. Icho ndicho chakanyanya kuenderera mberi chiyero here? Average level? Peak level? Uye inochengetedza kwenguva yakareba sei, uye nemhando ipi yemashoko? Idziwo mibvunzo inokosha.
Zvinosuruvarisa, kwakave kune mitemo yakawanda uye inopesana yekuyera sangano rekugadzirisa masimba, yakabudiswa ne Audio Audio Society (AES), Electronics Industries Association (EIA) uye International Electrotechnical Commission (IEC). Izvo zvinoshamisika kuti sei munhu wepakati pevamwe angagumisa zvishoma kuvhiringidzika.
Pamusoro pezvo, vazhinji vevakiki vatakambotaura navo havasi kutevera mitemo iyi; ivo vanongotanga kuverenga. Kazhinji, chisarudzo ichi chinobva pane simba rekushandisa kwe subwoofer. (Simba kugadzirisa zvinyorwa pamusoro pevatambi vanokanganisa vatauriri, vakadai sewaofers uye tweeters, vanonyanya kuenzaniswa uye vane chinangwa kudarika zvinyorwa zvevakaperera vakakwana.) Dzimwe nguva kutaura kwemasimba kugadzirisa kunobva pakushambadzira. Iwe unogona kuona kana munhu anogadzira kupa mutauriri anodhura kune simba rinopfuura rekugadzirisa kutarisana nemukurukuri-mutengo wakadzika, kunyange zvazvo vose vari vaviri vanoshandisa yeoofer imwe chete.
Bhuku Rezvokudya vs. Amplifier Power
Zvakakosha kunzwisisa kuti mumamiriro ezvinhu akawanda, 200-watt amp inopa simba rakafanana sa 10-watt amp. Ichi ndechokuti kuteerera kwose kunowanikwa pamwero wepamusoro, uko pasi pe1 watt nesimba rakakwana kune vatauri . Kupinda muhurukuro yakapiwa mutoro pane imwe nzvimbo yakagadzirirwa, zvese zvinokurudzira zvinopa simba rakafanana remasimba - chero bedzi ivo vachikwanisa kuunza simba guru iroro.
Saka ndiyo chaiyo inogadziridza iyo iyo inofanirwa, kwete simba rekusimudzira. Kana iwe usati uchinge uchinge wakagadzirisa hurongwa hwako kusvika kumazinga apo ivhu risina kugadzikana, yako amp angatomboti yakabudisa kupfuura 10 kana 20 watts. Nokudaro, iwe unogona kuchengetedza zvakakwana 1-watt amplifier mudiki 2-inch inotaura. Ingotendeuka iyo yepamusoro pane izvo mukurukuri anogona kuita.
Izvo zvausingafaniri kuita ndevha amp-powered amp - iti, 10-kana 20-watt model - mudivi rinowirirana uye shandura inzwi richikwira. Iko-powered-amp-power inogona kukanganisa (kukanganisa), uye kukwegura kwemagetsi ndeye chikonzero chinonyanya kukosha chekutauri kukanganisa. Apo yako yakagadzirisa iri kuvhara, inonyatsokonzera dhigirii yepamusoro DC yakananga mumutauri. Izvi zvinogona kupisa kunze kwezwi revatyairi vevatauri rinowedzera pakarepo!
Nzira Yokuverenga Nhamba yeiyo Amp Unoda
Kuvhiringidza sezvo zvose izvi zvingaita sezviri nyore, zviri nyore kuverenga kuti chii chamakukura chamunoda. Uye chikamu chakanakisisa ndechokuti iwe unogona kuita izvi mumusoro wako. Izvo hazvizove zvakakwana, nokuti iwe uchange uchitenderera pane zvakataurwa kubva kumukurukuri uye kukurudzira, izvo zvisinganzwisisiki uye dzimwe nguva kuwedzererwa. Asi zvichakuvharira zvakakwana. Heino nzira yekuzviita nayo:
- Tora kukosha kwekunzwisisa kwemukurukuri , iyo inoratidzwa mumagetsi (dB) pa 1 watt / 1 mita. Kana yakanyorwa se-muimba kana hafu-space spec, shandisa iyo nhamba. Kana iri anechoic spec (yakafanana neyo inowanikwa mune zvimwe zviongorori zvemukurukuri) add +3 dB. Nhamba yaunayo iye zvino ichakuudza zvakajeka kuti mukurukuri achamhanya sei pachigaro chako chekunzwa nechitinha che-1-watt.
- Zvatinoda kusvika kune huwandu hwesimba hunodiwa kutora zvishoma 102 dB, iyo inofanana nepamusoro pevanhu vakawanda vanoda kufara. Izvo zvakanyanya sei izvozvo? Wambove uri mumutambo mukuru wemafirimu? Nhandare yakanyatsogadziriswa inoshandiswa paanotarisa yepamusoro ichakupa inenge 105 dB yega yega. Izvo zvinonzwika zvikuru -zvinokurudzira kupfuura vanhu vakawanda vanoda kunzwa - ndicho chikonzero nei nzvimbo dzemafirimu dzisingawanzoiti mafirimu pamitambo yakawanda yakakwirira. Saka 102 dB inogadzirira zvakanaka.
- Heino chinhu chinokosha chaunoda kuziva; kuti uwane iyo yakawanda +3 dB yehuwandu, iwe unoda kuwedzera simba re amp amp. Saka kana iwe uine hurukuro ine-in-room senitivity ye 88 dB pa 1 watt, ipapo 2 watts ichakutora 91 dB, 4 watts ichakutora 94 dB, nezvimwe zvakadaro. Ingoverengera kubva ipapo: 8 watts inokuwana iwe 97 dB, 16 watts inokutora 100 dB, uye 32 watts inokuwana iwe 103 dB.
Saka izvo zvaunoda ndeyekusimudza zvinokwanisa kutora 32 watts. Zvechokwadi, hapana anoita 32-watt amp, asi 40- kana 50-watt receiver kana amplifier anofanira kuita zvakanaka. Kana iyo yaunoda kana yawakagamuchira ichibudisa, iti, 100 watts, usanetseka pamusoro payo. Yeuka, pamusana pekuteerera mazinga nevanowanzoti vakurukuri, chero ipi zvayo iri kubudisa kunze kwema 1 watt, zvakadaro.
