Maitiro ekusarudza amplifiers uye vatauri vebass magitare?

Iyo bass gitare yakakosha kupfuura amplifier yatinoibatanidza nayo? Uyu mubvunzo hausi panzvimbo, nekuti yakaderera-mhando bass inonzwika yakaipa pane yakanaka amplifier, asi chiridzwa chikuru chakasanganiswa neamp amp haizonzwika zvakanaka zvakare. Mugwaro rino, tichabata nemaamplifiers nemagudzanzwi.

Rambi kana transistor?

"Lamp" - tsika kwemakumi emakore, classic, rounder sound. Zvinosuruvarisa, kushandiswa kwechubhu amplifiers kunosanganisira kudiwa kwekutsiva machubhu nguva nenguva, iyo inowedzera zvakanyanya mari yekushanda yechubhu "furnaces", iyo ichiri kudhura kupfuura vakwikwidzi vavo. Makwikwi aya ane transistor amplifiers. Inzwi harienderane nechubhu amplifiers, kunyangwe nhasi tekinoroji iri kufamba nekukurumidza zvekuti mainjiniya ari kuswedera pedyo nekusvika kune sonic maitiro emachubhu kuburikidza ne transistors. Mu "transistors" haufanirwe kutsiva machubhu, uye kunze kweiyo, transistor "furnaces" inodhura kupfuura iyo tube. Mhinduro inonakidza ndeye hybrid amplifiers, kusanganisa chubhu preamplifier ne transistor simba amplifier. Iwo akachipa kupfuura chubhu amplifiers, asi achiri kutora mamwe e "tube" ruzha.

"Mumhanzi" vavakidzani

Iwe unofanirwa kufunga nezve iyo imwe neimwe chubhu amplifier inoda kushandurwa kusvika kune imwe nhanho kuti inzwike yakanaka. Transistor amplifiers haina matambudziko nazvo, inonzwika zvakanaka kunyangwe pakaderera vhoriyamu mazinga. Kana isu tisina vavakidzani vanotamba, semuenzaniso, hwamanda kana saxophone, kuparadzanisa "mwenje" inogona kuva dambudziko guru. Pamusoro pezvo, zvinowedzerwa nenyaya yekuti ma frequency akaderera ari nani kupararira pamadaro marefu. Kugara muguta, unogona kuita kuti hafu yevhavha irege kutifarira. Tinogona kutamba takanyarara kumba pane yakakura solid-state amplifier uye rock kunze kumakonzati. Iwe unogona nguva dzose kusarudza duku tube amplifier nehurukuro duku, asi zvinosuruvarisa pane imwe "asi". Pamabass magitare, vatauri vadiki vanonzwika zvakanyanya kupfuura hombe nekuti ivo havana kunaka zvakakwana kuendesa yakaderera ma frequency, asi zvimwe pane izvo gare gare.

Musoro + mbiru kana combo?

Combo iamplifier ine loudspeaker mune imwe imba. Musoro ndiyo unit inosimudzira chiratidzo kubva pachiridzwa, basa rekuunza iyo yakatokwidziridzwa chiratidzo kune gudzanzwi. Musoro uye mbiru pamwe chete murwi. Zvakanakira comba zviri nani kufamba. Nehurombo, vanoita kuti zviome kutsiva gudzanzwi, uyezve, ma transistors kana machubhu anooneswa zvakananga kune yakakwirira ruzha. Izvi zvinokanganisa basa ravo kusvika pamwero wakati. Mune akawanda combos ichokwadi kuti mutauri akaparadzana anogona kubatanidzwa, asi kunyangwe tikadzima yakavakirwa-mukati, isu tichiri kumanikidzwa kutakura iyo yose combo chimiro kana tichifambisa amplifier kubva kune imwe nzvimbo kuenda kune imwe nzvimbo, asi panguva ino ine mutauri akasiyana. Panyaya yemastacks, isu tine nharembozha uye mashoma nharembozha, izvo zvakabatana idambudziko rakaoma pakufambisa. Zvisinei, tinogona kusarudza gudzanzwi remusoro maererano nezvatinofarira. Mukuwedzera, ma-transistors kana machubhu mu "musoro" haaoneki kumanikidziro ezwi, nokuti ari mune imwe imba yakasiyana neine gudzanzwi.

Saizi yemutauri uye nhamba yemakoramu

Kune ma bass guitars, 15 ”speaker ndiyo yakajairwa. Izvo zvakakosha kuti utarise kuti iyo loudspeaker (izvi zvinoshandawo kune yakavakirwa-mukati gudzanzwi mu combach) ine tweeter. Kazhinji kacho i1 ”uye inowanikwa mukoramu imwe chete nemutauri mukuru. Izvo hazvifanirwe hazvo, asi nekuda kwazviri, iyo bass gitare inowana yakawedzera kutaurwa chikomo, yakakosha mukupwanya nemusanganiswa kana uchitamba neminwe yako kana minhenga, uye kunyanya neiyo clang maitiro.

Iyo hombe yegudzanzwi, zviri nani iyo inogona kubata yakaderera frequencies. Ndosaka vanoridza mabhesi vachiwanzosarudza masipika ane 15 “kana kunyange 2 x 15” kana 4 x 15 “zvitauriri. Dzimwe nguva masanganiswa ane 10 ”speaker anoshandiswawo. Iyo gumi neshanu "mutauri anopa mabhesi makuru, uye gumi" ane basa rekutyora mubhendi repamusoro (basa rakafanana rinoitwa nema tweeters akavakirwa muvakurukuri vane gumi neshanu" mutauri. Dzimwe nguva vatambi vebhesi vanotosarudza kuenda kunyange 15 x 10 "kana 15 x 2" kusimbisa kubudirira mubhendi repamusoro. Iyo bass inobuda imomo ichave yakaoma zvakanyanya uye yakanyanya kutariswa, izvo zvingave zvinodiwa muzviitiko zvakawanda.

Pane mimwe mitemo yekuchengeta mupfungwa pakusarudza makoramu. Ndichakupa nzira dzakachengeteka. Kune, hongu, vamwe, asi ngatitarisei kune avo vasiri panjodzi huru. Kana iwe usina chokwadi chechinhu chipi nechipi, bvunza nyanzvi. Kwete kutamba nemagetsi.

Kana zvasvika kune simba, tinogona kusarudza gudzanzwi rakaenzana nesimba reiyo amplifier. Isu tinogonawo kusarudza gudzanzwi rine simba rakaderera pane iyo amplifier, asi zvino iwe unofanirwa kuyeuka kusabvisa iyo amplifier zvakanyanya, nekuti unogona kukuvadza vatauri. Mukuwedzera, iwe unogona zvakare kusarudza gudzanzwi rine simba rakakwirira kupfuura amplifier. Muchiitiko ichi, haufanirwe kuwedzeredza nekubvisa amplifier, kuti urege kuikuvadza, nekuti zvinogona kuitika kuti isu tichaedza kushandisa zvizere kugona kwevatauri pamutengo wese. Kana tikashandisa mwero, zvinhu zvose zvinofanira kuva zvakanaka. Imwezve chinyorwa. Semuenzaniso, amplifier ine simba re 100 W, inotaura colloquially, "inopa" 200 W kune 100 W mutauri. mumwe nomumwe wavo.

Kana zvasvika kune impedance, yakati siyanei. Kutanga iwe unofanirwa kutarisa kana uine parallel kana serial yekubatanidza. Muzviitiko zvakawanda, zvinoitika zvakafanana. Saka kana tiine chinongedzo chakafanana kune amplifier, semuenzaniso ine impedance ye8 ohms, tinobatanidza imwe 8-ohm speaker. Kana ukafunga kushandisa magudzanzwi maviri, unofanira kushandisa 2 2 – ohm magudzanzwi eimwe amplifier. Nekudaro, kana isu tiine nhevedzano yekubatanidza, isu zvakare tinobatanidza imwe 16-ohm speaker kune amplifier ine impedance ye8 ohms, asi apa ndipo panopera kufanana. Munyaya yekubatanidza kwakatevedzana, maviri 8-ohm makoramu anogona kushandiswa kune imwechete amplifier. Zvimwe zvinosiyana zvinogona kuitwa, asi kukanganisa kunogona kuva nemigumisiro yakakomba. Kana iwe usiri 2% chokwadi, tevera iyi mitemo yakachengeteka.

Kutsvaga chii?

Bass amplifiers kazhinji inongova ne1 chiteshi chakachena, kana 2 chiteshi chakachena uye chakakanganiswa. Kana tikasarudza amplifier isina chiteshi chekukanganisa, isu tinorasikirwa nemukana wekuwana yakakanganiswa ruzha chete nekuda kweamplifier. Iri harisi dambudziko guru. Muchiitiko ichocho, ingotenga kukanganisa kwekunze. Unofanirawo kuteerera kururamiswa. Mamwe amplifiers anopa akawanda-bhendi EQ yemabhendi ega, asi mazhinji anongopa "bass - yepakati - treble" EQ. Kazhinji, mabass amplifiers akashongedzerwa ane limiter (yakanyanya kusetwa compressor), iyo inodzivirira amplifier kubva pakukanganiswa kusingadiwe. Uye zvakare, iwe unogona kuwana yakasarudzika compressor inoenzana vhoriyamu mazinga pakati pekutamba zvinyoro uye zvehasha. Dzimwe nguva modulation uye spatial mhedzisiro inovakwa mukati, asi izvi zvinongori zvekuwedzera uye hazvikanganise ruzha rwekutanga. Kana iwe uchida kushandisa ekunze modulation uye yakatenderedza mhedzisiro, tarisa kana iyo amplifier ine yakavakirwa-mukati FX loop. Iyo modulation uye spatial mhedzisiro inoshanda zvirinani neamp kuburikidza ne loop pane pakati pebass neamp. Iyo wah - wah, kukanganisa uye compressor inogara yakavharirwa pakati peamplifier nechiridzwa. Izvo zvakakosha kuti utarise kana iyo amplifier inopa musanganiswa kubuda. Iyo bass inowanzorekodhwa mutsara, uye pasina kuburitsa kwakadaro hazvigoneke. Kana mumwe munhu achida mahedhifoni anobuda, zvakakoshawo kuve nechokwadi kuti iri mune yakapihwa amplifier.

Summation

Izvo zvakakosha kubatanidza mabhesi kune chimwe chinhu chakakosha, nekuti basa reamplifier mukugadzira ruzha rakakura. Nyaya ye "chitofu" haifaniri kurerutswa kana uchida kunzwika zvakanaka.
