Kana zvasvikamidziyo yekuteerera, iyo amplifier inoita basa rakakosha pakuona iyo yakazara ruzha mhando ye system. Pakati pezvakawanda zvinotsanangurwa izvotsanangura kuita kweamplifier, frequency response range ndeimwe yeanonyanya kukosha parameters. Kunzwisisa kuti frequency response range inobata seisound qualityinogona kubatsira audiophiles uye vateereri vese kuita sarudzo dzine ruzivo pakusarudza michina yekuteerera.

Chii chinonzi frequency response?

Frequency mhinduro inoreva huwandu hwemafrequency ayo amplifier inogona kunyatso kubereka. Inowanzoyerwa muHertz (Hz) uye inoratidzwa senge renji, senge 20 Hz kusvika 20 kHz. Iri renji rinovhara huwandu hwemafrequency anonzwika kuvanhu uye inowanzoonekwa sekubva pa20 Hz (bhesi rakaderera) kusvika ku20 kHz (yepamusoro treble). Iyo amplifier ine yakakura frequency mhinduro renji inogona kubereka yakafara spectrum, ichivandudza zvakanyanya ruzivo rwekuteerera.

Kukosha kweFrequency Response Range

1. Bass Reproduction: Iyo yakaderera yekupedzisira yefrequency spectrum, kazhinji iri pasi pe100 Hz, ndiko kunogara mabhesi. Iyo amplifier inokwanisa kunyatso kubereka aya akadzika ma frequency anozoguma nekupfuma, kwakawandainonyudza ruzha ruzivo.Zvemhando dzinodabass yakadzika, zvakadai semagetsi, hip-hop, uye classical music, amplifier ine frequency response inoenda ku20 Hz inogona kuvandudza zvakanyanya kunaka kwezwi.

2. Midrange Clarity: Midrange frequencies (inenge 300 Hz kusvika 3 kHz) inokosha pakujeka kwezwi uye manzwiro echisikigo ezviridzwa. Amplifier inokunda mune iyi chiyero inovimbisa kuti mazwi uye zviridzwainzwi rakajekauye sehupenyu. Kana mhinduro yefrequency yakaganhurwa kune iyi mutsara, ruzha rwunoita madhaka uye rusina kujeka, ruchikanganisa kuterera kwese.

3.Treble Detail: Mafambiro epamusoro, kunyanya ayo ari pamusoro pe3 kHz, anobatsira kune zvakadzama uye kujeka kwenzwi. Zviridzwa zvakaita semakandira, nyere, uye violin zvinoburitsa kurira mumutsara uyu. Iyo amplifier inokwanisa kunyatso kubereka aya mafrequency inogona kupa nzvimbo uye ruzivo, ichivandudza huwandu hweruzha rwemhando. Kusakwana kwefrequency mhinduro mu treble renji kunogona kukonzera kugomara kanainzwi risina upenyu.

Kupindura kwefrequency kunokanganisa kunaka kwenzwi

An amplifier's frequency response range inokanganisa zvakananga kuti inobereka sei marudzi akasiyana emasaini masaini.Hedzino dzimwe dzenzira huru dzefrequency response inokanganisa kunaka kwezwi:

1. Kumonya uye Mavara: Kana amplifier isingakwanisi kubereka mamwe mafrequency, inogona kuunza kukanganisa kana kuti ruvara kune ruzha. Semuenzaniso, kana iyo amplifier isingakwanise kubata yakaderera ma frequency zvakanaka, inogona kuburitsa yakashatiswa bass isina kujeka. Uku kukanganisa kunonyanya kuoneka mundima dzakaoma umo zviridzwa zvakawanda zviri kurira panguva imwe chete.

2. Dynamic Range: Anamplifier's dynamic rangeinoreva musiyano pakati pemavhoriyamu akanyarara uye ane ruzha zvakanyanya anogona kubereka. Iyo yakafara frequency mhinduro renji inowanzoreva yakakura simba renji, iyo inobvumira iyo amplifier kubata zvidiki nuances uye ane simba crescendos pasina kukanganisa. Kugona uku kwakakosha kumhando dzinotsamira pakusiyana kwakasiyana, semumhanzi wekirasi uye jazz.

3. Phase Response: Frequency mhinduro hairevi chete kukura kweruzha pama frequency akasiyana, asi inosanganisirawo mhinduro yechikamu, inova nguvamasaisai enzwi. Amplifiers ane yakashata chikamu chekupindura anogona kukonzera matambudziko enguva, kuita kuti ruzha risawirirane kana kusawirirana. Izvi zvinonyanya kukuvadza mukuseta stereo, uko kufungidzira kwakaringana uye ndima yekurira kwakakosha kuneruzivo rwekuteerera rwakanyura.

4. Kuenderana ne vatauri: Iyo frequency mhinduro yeamplifier inofanirwawo kuenderana nevatauri vainotyaira. Kana iyo amplifier ine shoma frequency mhinduro, inogona kusashandisa zvizere kuita kwemutauri wemhando yepamusoro. Sezvineiwo, yemhando yepamusoro amplifier ine yakakura frequency mhinduro inogona kushandisa zvizere kuita kwemukurukuri kusvika pakugona kwayo.

Kusarudza Amplifier Yakarurama

Rinikusarudza amplifier, zvakakosha kuti titarise frequency renji yekupindura pamwe nezvimwe zvakatemwa senge zvachose harmonic distortion (THD), chiratidzo-ku-ruzha ratio (SNR), uye kubuda kwesimba. Iyo inonyatsoita amplifier haina chete yakafara frequency mhinduro asiwo yakaderera kukanganisa uyesimba guru rinobudakutyaira zvinobudirira vakurukuri.

Kune maaudiophiles, zvinokurudzirwa kuteerera kune akasiyana amplifiers munzvimbo inodzorwa kuti uongorore mhando yavo yekurira. Ngwarira kune kuti iyo amplifier inoburitsa sei bass, yepakati-renji, uye treble frequency. Iyo yakanaka amplifier inofanira kupa ruzha rwakadzikama mukati mese frequency spectrum, zvichikonzera chiitiko chekuteerera chinonakidza.

Mukupedzisa

Muchidimbu, iyo frequency mhinduro renji yeamplifier chinhu chakakosha chinokanganisa zvakanyanya kunaka kwekurira. Mhinduro yefrequency yakawanda inobvumira kubereka kuri nani kwebass, kujeka kwepakati-renji, uye treble ruzivo, zvese izvi zvinobatsira kune inonyudza uye inonakidza yekuteerera chiitiko. Nekunzwisisa kukosha kwekupindura kwema frequency, vatengi vanogona kuita sarudzo dzine ruzivo pakusarudza maamplifiers, vachiona kuti vanowana yakanakisa ruzha rwemhando kubva kumaodhiyo avo masisitimu. Kunyangwe iwe uri muteereri anongoteerera kana akarevesa audiophile, kuterera kune frequency mhinduro kunogona kutora yako yekuteerera kukwirisa.
