Mumazuva anomasisitimu eruzha,Hapana mubvunzo kuti ma amplifiers ndeimwe yezvinhu zvakakosha zvikuru. Hazvingokanganisi chete kunaka kweruzha, asi zvinosarudzawo mashandiro ese uye ruzivo rwemushandisi wesystem. Chinyorwa chino chichaongorora zvinhu zvikuru zvema amplifiers emagetsikuti zvikubatsire kunzwisisa kuti nei zvinhu izvi zvichikosha kudaro.
1. Simba rinobuda: Dhonza moyo wehwamanda
Rimwe remabasa makuru eamplifier nderekupa simba rakakwana rekufambisa speaker. Simba rinobuda rinoona kana system yeaudio ichigona kuchengetedza ruzha rwakajeka uye rusina kukanganiswa pamavhoriyamu akasiyana-siyana. Simba rinobuda reamplifier rinowanzo ratidzwa mu watts (W). Kusarudza amplifier yakakodzera kunoda kufunga nezvezvinhu zvinotevera:
Simba remutauri rakarongwa: Simba remutauri rinofanira kuenzana nesimba remutauri rakarongwa. Simba shoma rinogona kukonzera kusakwana kwenzwi uye kukanganisa, nepo simba rakawandisa richigona kukuvadza mutauri.
Kukura kwekamuri nenzvimbo inonzwika: Mumakamuri makuru kana munzvimbo dzisina ruzha rwakanyanya, ma amplifiers ane simba rakawanda anodiwa kuti ave nechokwadi chekuti ruzha rwakafanana uye rwakajeka.
Rudzi rwemimhanzi uye tsika dzekuteerera: Vashandisi vanofarira kuteerera mimhanzi ine simba guru vanogona kuda ma amplifiers ane simba rakawanda kuti varambe vaine ruzivo rwakadzama uye mafambiro emimhanzi yacho pahuwandu hwakawanda.
2. Kukanganiswa: Chinhu chisingaoneki chinouraya ruzha rwemhando yepamusoro
Kukanganiswa kwesimba chimwe chezviratidzo zvakakosha zvekuongorora mhando yema amplifiers emagetsi. Zvinoreva chero shanduko dzisina kufanira muchiratidzo chekupinda panguva yekuwedzera simba. Kune mhando dzinotevera dzekukanganiswa:
Harmonic distortion: Kuwanda kwema frequency anowanikwa panguva yekuwedzera ma signal. Kukanganisa uku kunogona kuita kuti ruzha rusave rwechisikigo uye kukanganisa kunaka kweruzha.
Kukanganiswa kwezwi pakati pemamodulation: frequency itsva inogadzirwa kana zviratidzo zvemafrequencies akasiyana zvasanganiswa muamplifier, izvo zvinogona kutungamira kumanzwi asingadiwe musignal yeaudio.
Kukanganiswa kweTrans-conductance: Hukama husina kurongeka pakati pekubuda kwesimba remagetsi nechiratidzo chekupinda, chinowanzoitika panguva yekuwedzerwa kwesimba.
Dhizaini yakanaka kwazvo yeamplifier inoderedza kukanganisa uku uye inopa ruzha rwakajeka uye rwechisikigo.
3. Kupindura kakawanda: Kudzorera hupamhi nehupamhi hweruzha
Mhinduro yefrequency inoreva huwandu hwefrequency hunogona kukwidziridzwa nepower amplifier zvinobudirira, inowanzo kuyerwa muHertz (Hz). Amplifier yakakodzera inofanira kupa amplification yakapfava uye yakafanana muaudio spectrum yese (kazhinji kubva pa20Hz kusvika 20kHz). Kuenzana kwemhinduro yefrequency kunokanganisa zvakananga mhedzisiro yekudzoreredzwa kweruzha:
Mhinduro yakaderera: inokanganisa kudzika uye kukanganiswa kwebass. Ma amplifiers ane mhinduro yakanaka yakaderera anogona kupa mhedzisiro yakasimba yebass.
Mhinduro yepakati pemafrequency: inonyanya kukanganisa mashandiro emanzwi nezviridzwa, uye ndiyo chikamu chikuru chemhando yeruzha.
Mhinduro yefrequency yakakwira: Inokanganisa kujeka uye mashandiro eruzivo rwemanotsi akakwira, uye amplifier yesimba ine mhinduro yakanaka yefrequency yakakwira inogona kuita kuti ruzha ruve pachena uye rwechokwadi.
4. Chiyero chechiratidzo kune ruzha (SNR): vimbiso yemhando yeruzha rwakachena
Chiyero cheSignal to Noise chiratidzo chinoyera chiyero chiri pakati pechiratidzo chinobatsira uye ruzha muchiratidzo chinobuda chepower amplifier, chinowanzo ratidzwa muma decibel (dB). Chiyero chepamusoro chesignal-to-noise zvinoreva kuti power amplifier inogadzira ruzha rushoma rwekumashure painowedzera chiratidzo, zvichiita kuti ruzha ruve rwakachena. Kusarudza power amplifier ine chiyero chepamusoro chesignal-to-noise kunogona kuderedza kupindira kwenzwi uye kupa ruzivo rwekuteerera rwakadzama.
5. Kugadzirwa kwecircuit yema amplifiers emagetsi: chinhu chikuru pakusarudza mashandiro
Dhizaini yemuchina wekusimbisa simba inokanganisa mashandiro awo uye kunaka kweruzha. Kune magadzirirwo akasiyana-siyana emuchina wekusimbisa:
Amplifier yeKirasi A: Neruzha rwemhando yepamusoro asi kushanda kwayo kwakaderera, yakakodzera masisitimu epamusoro-soro eaudio anotevedzera ruzha rwemhando yepamusoro.
Amplifier yeClass B: Inoshanda zvakanyanya asi ine kukanganisa kukuru, inowanzoshandiswa mumasisitimu enzwi ari pakati nepakati kusvika pasi.
Kirasi AB amplifier: Inosanganisa zvakanakira Kirasi A neKirasi B, iine kushanda kwepamusoro uye ruzha rwemhando yepamusoro, uye parizvino ndiyo dhizaini huru yeamplifier.
Kirasi D amplifier: Nekushanda kwakanyanya uye saizi diki, yakakodzera michina inotakurika uye masisitimu emazuva ano emitambo yemumba.
Dhizaini yega yega yedunhu ine zvayakanakira nezvayakaipira, uye kusarudza mhando yeamplifier inokodzera zvaunoda kwakakosha.
6. Mabasa uye mashandisirwo ema amplifiers emagetsi: kusangana nezvinodiwa zvakasiyana-siyana
Ma amplifiers emazuva ano haangodi chete ruzha rwemhando yepamusoro, asiwo anoda kupa mabasa akapfuma uye ma interfaces kuti aenderane nemamiriro akasiyana-siyana ekushandiswa. Semuenzaniso:
Ma "input interfaces" akawanda, akadai seRCA, fiber optic, coaxial, HDMI, nezvimwewo, anoita kuti zvive nyore kubatanidza michina yakasiyana-siyana ye "audio source".
Kubatana kusina waya: senge Bluetooth neWiFi, zviri nyore kubatanidzwa nemafoni uyemasisitimu edzimba akangwara.
Rutsigiro rwemachiteshi akawanda: rwakakodzeramasisitimu emitambo yepamba, zvichipa ruzivo rwekurira rwakanyura zvakanyanya.
Kusarudza amplifier yakanaka kunoda kutariswa kwakazara kwezvinhu zvakaita sekubuda kwesimba, kukanganiswa, mhinduro yefrequency, chiyero chesignal-to-noise, dhizaini yedunhu, mashandiro, uye ma interfaces. Nenzira iyi chete tinogona kuve nechokwadi chekuti system yeaudio inoshanda zvakanaka uye ruzivo rwemushandisi rwakanaka. Ungave uri munhu anofarira mimhanzi kana kuti munhu anofarira theatre yepamba, kunzwisisa uye kuteerera zvinhu izvi zvakakosha kuchakubatsira kusarudza amplifier inokukodzera zvakanyanya, zvichiita kuti chiitiko chega chega chekuteerera chive chinonakidza.
