Kana zvasvika pamichina yekuteerera, amplifier inoita basa rakakosha pakuona mhando yeruzha rwese rwesystem. Pakati pezvakawanda zvinodiwa izvotsanangura mashandiro eamplifier, huwandu hwemhinduro dzema frequency ndeimwe yematanho akakosha. Kunzwisisa kuti huwandu hwemhinduro dzema frequency hunokanganisa seikunaka kweruzhazvinogona kubatsira vanhu vanofarira kunzwa uye vateereri vakawanda kuti vasarudze zvine ruzivo pavanenge vachisarudza michina yekuteerera.

Chii chinonzi frequency response?

Mhinduro yefrequency inoreva huwandu hwemafrequence anogona kuburitswa neamplifier zvinobudirira. Inowanzo kuyerwa muHertz (Hz) uye inoburitswa sehuwandu, senge 20 Hz kusvika 20 kHz. Huwandu uhwu hunofukidza huwandu hwemafrequence anonzwika kuvanhu uye hunowanzoonekwa sehunobva pa20 Hz (bass yakaderera) kusvika ku20 kHz (treble yepamusoro). Amplifier ine frequency response range yakakura inogona kudzokorora spectrum yakakura, zvichivandudza zvakanyanya ruzivo rwekuteerera.

Kukosha kweFrequency Response Range

1. Kuburitswa kweBass: Mugumo wakaderera wefrequency spectrum, kazhinji uri pasi pe100 Hz, ndipo panogara mafrequency ebass. Amplifier inogona kunyora nemazvo mafrequency aya akaderera ichaita kuti pave nehupfumi hwakawanda uye hwakawanda.ruzivo rwekurira zvine mutsindo.Kune marudzi anodabass yakadzika, zvakaita semimhanzi yemagetsi, hip-hop, uye mimhanzi yekare, amplifier ine mhinduro yefrequency inosvika ku20 Hz inogona kuvandudza zvakanyanya kunaka kweruzha.

2. Kujeka kwepakati pemanzwi: Mafrequency epakati pemanzwi (anenge 300 Hz kusvika 3 kHz) akakosha pakujeka kwenzwi uye nzwi rezviridzwa. Amplifier inobudirira muhuwandu uhwu inoita kuti manzwi nezviridzwa zvinzwike zvakanaka.zvinonzwika zvakajekauye zvakafanana nehupenyu. Kana mhinduro yefrequency yakaganhurirwa kune iyi range, ruzha ruchava rusina kujeka uye rusina kujeka, zvichikanganisa ruzivo rwese rwekuteerera.

3.Treble Detail: Mafrequency akakwira, kunyanya ari pamusoro pe3 kHz, anobatsira mukuita kuti ruzha ruve rwakajeka uye ruve rwakajeka. Zviridzwa zvakaita secymbals, nyere, uye violin zvinoburitsa ruzha rwuri muchikamu ichi. Amplifier inogona kunyora mafrequency aya nemazvo inogona kupa nzvimbo neruzivo, zvichivandudza kunaka kweruzha. Kusakwana kwemhinduro yemafrequency muchikamu chetreble kunogona kukonzera kusviba kanaruzha rusina hupenyu.

Maitiro ekupindurwa kwema frequency anokanganisa kunaka kweruzha

Rudzi rwemhinduro yemafrequency eamplifier runokanganisa zvakananga kuti inobereka sei mhando dzakasiyana dzezviratidzo zvemanzwi.Heano mamwe enzira huru dzinoshandiswa nefrequency response pakuita kuti ruzha ruve rwakanaka:

1. Kukanganiswa uye Kuchinja Ruvara: Kana amplifier ikasakwanisa kuburitsa mamwe mafrequency, inogona kukonzera kukanganiswa kana ruvara kunzwi. Semuenzaniso, kana amplifier ikasagona kubata mafrequency akaderera zvakanaka, inogona kuburitsa bass yakakanganiswa isina kujeka. Kukanganiswa uku kunonyanya kuonekwa munzvimbo dzakaoma uko zviridzwa zvakawanda zviri kurira panguva imwe chete.

2. Dynamic Range: Annzvimbo inoshanduka yeamplifierzvinoreva musiyano uripo pakati pemavhoriyamu akanyarara uye ane ruzha rwakanyanya rwaanogona kubereka. Frequency response range inowanzoreva dynamic range yakakura, iyo inobvumira amplifier kubata nuances dzakapfava uye crescendos dzine simba pasina kukanganisa. Kugona uku kwakakosha kune marudzi anovimba nedynamic contrast, senge mimhanzi yekare nejazz.

3. Mhinduro yePasi: Mhinduro yefrequency haingorevi chete kukura kweruzha pamafrequencies akasiyana, asiwo inosanganisira mhinduro yephase, inova nguva yemafungu eruzha. Maamplifier asina mhinduro yakanaka yechikamu anogona kukonzera matambudziko enguva, zvichiita kuti ruzha rusawirirane kana kuti rusawirirane. Izvi zvinonyanya kukanganisa mu stereo setup, uko mifananidzo chaiyo nenzvimbo yeruzha zvakakosha kuneruzivo rwekuteerera rwakadzama.

4. Kuenderana ne masipika: Mhinduro yefrequency yeamplifier inofanirawo kuenderana nemaspika ayo. Kana amplifier ine mhinduro shoma yefrequency, ingasashandise zvizere mashandiro espika yemhando yepamusoro. Kusiyana neizvi, amplifier yemhando yepamusoro ine mhinduro yefrequency yakakura inogona kushandisa zvizere mashandiro espika kusvika pakukwanisa kwayo kwakanyanya.

Kusarudza Amplifier Yakakodzera

Rinikusarudza amplifier, zvakakosha kufunga nezvehuwandu hwemhinduro dzema frequency pamwe chete nezvimwe zvinhu zvakaita se total harmonic distortion (THD), signal-to-noise ratio (SNR), uye simba rinobuda. Amplifier inoshanda zvakanaka haina chete mhinduro ye frequency yakakura asiwo ine distortion yakaderera uyesimba guru rinobudakufambisa maspika zvinobudirira.

Kune vanoda kunzwa, zvinokurudzirwa kuteerera ma amplifiers akasiyana munzvimbo inodzorwa kuti vaongorore kunaka kweruzha rwavo. Tarisa kuti amplifier inoburitsa sei bass, middle-range, uye treble frequency zvakanaka. Amplifier yakanaka inofanira kupa ruzha rwakaringana mu frequency yese, zvichikonzera kunzwa kunonakidza.

Mukupedzisa

Muchidimbu, huwandu hwemhinduro dzemafrequency eamplifier chinhu chakakosha chinokanganisa zvikuru kunaka kweruzha. Mhinduro yakakura yemafrequency inobvumira kuburitswa kwebass kuri nani, kujeka kwepakati, uye ruzivo rwe treble, zvese izvi zvinobatsira kune ruzivo rwakanyanya uye runonakidza rwekuteerera. Nekunzwisisa kukosha kwemhinduro yemafrequency, vatengi vanogona kuita sarudzo dzakagadzirwa neruzivo pavanenge vachisarudza maamplifiers, vachiona kuti vanowana mhando yepamusoro yeruzha kubva kumaaudio system avo. Ungave uri muteereri asina kurongeka kana kuti munhu anofarira kuteerera, kuteerera mhinduro yemafrequency kunogona kusimudzira ruzivo rwako rwekuteerera.
