Xa kufikwa kuizixhobo zomsindo, iamplifier idlala indima ebalulekileyo ekumiseleni umgangatho wesandi ngokubanzi wenkqubo. Phakathi iinkcukacha ezininzi ukubachaza ukusebenza kweamplifier, uluhlu lwempendulo ye-frequency yenye yezona pharamitha ezibalulekileyo. Ukuqonda ukuba uluhlu lwempendulo yefrikhwensi luchaphazela njaniumgangatho wesandiinokunceda i-audiophiles kunye nabaphulaphuli ngokubanzi benze izigqibo ezinolwazi xa bekhetha izixhobo zomsindo.

Yintoni impendulo rhoqo?

Impendulo yefrikhwensi ibhekiselele kuluhlu lwezandi ezinokuthi iamplifier ivelise kwakhona ngempumelelo. Ngokuqhelekileyo kulinganiswa kwi-Hertz (Hz) kwaye ibonakaliswe njengoluhlu, olufana ne-20 Hz ukuya kwi-20 kHz. Olu luhlu lugubungela i-spectrum yee-frequencies ezivakalayo ebantwini kwaye ngokuqhelekileyo ithathwa njengesuka kwi-20 Hz (eyona bass iphantsi) ukuya kuma-20 kHz (elona treble liphezulu). I-amplifier enoluhlu olubanzi lweempendulo zefrikhwensi inokuvelisa i-spectrum ebanzi, iphucula kakhulu amava okuphulaphula.

Ukubaluleka koluhlu lokuphendula rhoqo

1. I-Bass Reproduction: Isiphelo esisezantsi se-frequency spectrum, ngokuqhelekileyo ngaphantsi kwe-100 Hz, apho i-bass frequencies ihlala khona. I-amplifier enokuthi ivelise ngokuchanekileyo la maza aphantsi iya kubangela ubutyebi, ngakumbiamava esandi esintywilayo.Kwiintlobo ezifunayoi-bass enzulu, ezifana ne-elektroniki, i-hip-hop, kunye nomculo weklasikhi, i-amplifier ene-frequency response efikelela kwi-20 Hz inokuphucula kakhulu umgangatho wesandi.

2. Ukucaca okuphakathi: Iifrikhwensi zeMidrange (malunga ne-300 Hz ukuya kwi-3 kHz) zibalulekile ekucaciseni ilizwi kunye ne-timbre yendalo yezixhobo. I-amplifier egqwesileyo kolu luhlu iqinisekisa ukuba amazwi kunye nezixhoboisandi esicacileyokunye nobomi. Ukuba impendulo yefrikhwensi ikhawulelwe kolu luhlu, isandi siya kuba nodaka kwaye singacacanga, sichaphazela amava okuphulaphula ngokubanzi.

3.Treble Detail: Iifrikhwensi eziphezulu, ngakumbi ezo zingaphezulu kwe-3 kHz, zinegalelo kwinkcukacha kunye nokucaca kwesandi. Izixhobo zomculo ezifana namacangci, iifluti, neevayolin zivelisa izandi kolu luhlu. I-amplifier enokuthi ivelise ngokuchanekileyo ezi zihlandlo zinokunika indawo kunye neenkcukacha, ukuphucula umgangatho wesandi ngokubanzi. Ukunganeli kwempendulo yefrikhwensi kuluhlu lwetreble kunokubangela ukuba buthuntu okanyeisandi esingaphiliyo.

Indlela impendulo yefrikhwensi echaphazela ngayo umgangatho wesandi

Uluhlu lwempendulo ye-amplifier luchaphazela ngokuthe ngqo indlela evelisa ngayo iindidi ezahlukeneyoiimpawu zesandi.Nazi ezinye zeendlela eziphambili zokuphendula rhoqo okuchaphazela umgangatho wesandi:

1. Ukugqwetheka kunye neMibala: Ukuba iamplifier ayikwazi ukuvelisa amaza athile athile, isenokubangela ukugqwetheka okanye umbala kwisandi. Umzekelo, ukuba i-amplifier ayikwazi ukuphatha amaza aphantsi kakuhle, inokuvelisa i-bass egqwethekileyo engacacanga. Oku kugqwetheka kubonakala ngokukodwa kwiipaseji ezinzima apho izixhobo ezininzi zidlala ngaxeshanye.

2. Uluhlu lweDynamic: AnUluhlu oluguqukayo lweamplifieribhekisa kumahluko phakathi kowona mthamo uthuleyo nongxolayo unokuvelisa kwakhona. Uluhlu olubanzi lweempendulo zefrikhwensi ngokubanzi luthetha uluhlu olukhulu oluguquguqukayo, oluvumela i-amplifier ukuba iphathe iinuances ezifihlakeleyo kunye ne-crescendos enamandla ngaphandle kokuphazamiseka. Esi khono sibalulekile kwiintlobo ezixhomekeke kuthelekiso oluguquguqukayo, njengomculo weklasiki kunye nejazz.

3. Impendulo yeSigaba: Impendulo yefrikhwensi ibhekisa kungekuphela nje kububanzi besandi kwiifrikhwensi ezahlukeneyo, kodwa ikwabandakanya impendulo yenqanaba, elilixesha lesandi.amaza omsindo. Izikhulisi ezinempendulo yesigaba esibi zinokubangela iingxaki zexesha, zenze isandi singahambelani okanye singahambelani. Oku kuyingozi ngakumbi kulungiselelo lwesitiriyo, apho umfanekiso ochanekileyo kunye nendawo yesandi ibalulekile kwiamava okuphulaphula ngokunzulu.

4. Ukuhambelana ne izithethi: Ukuphendula rhoqo kweamplifier kufuneka kwakhona ihambelane nezithethi eziziqhubayo. Ukuba i-amplifier inempendulo yefrikhwensi encinci, ayinakusebenzisa ngokupheleleyo ukusebenza kwesithethi esikumgangatho ophezulu. Ngokwahlukileyo, i-amplifier yomgangatho ophezulu kunye nempendulo ebanzi ye-frequency inokusebenzisa ngokupheleleyo ukusebenza kwesithethi kumandla ayo aphezulu.

Ukukhetha iAplifier eLungileyo

Niniukukhetha iamplifier, kubalulekile ukuqwalasela uluhlu lweempendulo ze-frequency kunye nezinye iinkcukacha ezifana ne-harmonic distortion (THD), i-signal-to-noise ratio (SNR), kunye nokuphuma kwamandla. I-amplifier esebenza kakuhle ayinayo impendulo ebanzi kuphela kodwa kunye nokuphazamiseka okuphantsi kunyeimveliso yamandla aphezuluukuqhuba ngempumelelo izithethi.

Kwi-audiophiles, kuyacetyiswa ukuba umamele i-amplifiers ezahlukeneyo kwindawo elawulwayo ukuvavanya umgangatho wabo wesandi. Nika ingqalelo kwindlela iamplifier evelisa ngayo i-bass, i-mid-range, kunye ne-treble frequency. I-amplifier efanelekileyo kufuneka inike isandi esilungeleleneyo kuyo yonke i-spectrum yefrikhwensi, okukhokelela kumava amnandi okuphulaphula.

Ukuququmbela

Isishwankathelo, uluhlu lwempendulo ye-frequency ye-amplifier yinto ephambili echaphazela kakhulu umgangatho wesandi. Impendulo ebanzi yefrikhwensi ivumela ukuveliswa kwakhona kwe-bass, ukucaca okuphakathi koluhlu, kunye neenkcukacha ezijikelezayo, zonke ezinegalelo ekuntywilisweni ngakumbi kunye namava okuphulaphula. Ngokuqonda ukubaluleka kokuphendula rhoqo, abathengi banokwenza izigqibo ezinolwazi xa bekhetha i-amplifiers, beqinisekisa ukuba bafumana owona mgangatho wesandi ubalaseleyo kwiinkqubo zabo zomsindo. Nokuba ungumphulaphuli nje oqhelekileyo okanye i-audiophile enzulu, ukunikela ingqalelo kwimpendulo rhoqo kunokuthatha amava akho omsindo ukuya phezulu.
