1.Isipikha: ukuze sikwazi ukumelana nomthelela wokushaya kwenhliziyo okunamandla okungazelelwe esignalini yohlelo ngaphandle komonakalo noma ukuhlanekezela. Nasi inani elibonakalayo okufanele libhekiswe kulo: amandla alinganiselwe esipikha esikhethiwe kufanele abe kathathu kunalawo esibalo sethiyori.
2. I-Power amplifier: uma iqhathaniswa ne-transistor power amplifier, indawo yokugcina amandla edingekayo ihlukile. Lokhu kungenxa yokuthi ijika lokulayisha ngokweqile le-tube amplifier libushelelezi. Ngesiqongo sesignali yomculo egcwele ngokweqile, i-tube amplifier ayivezi ngokusobala into ye-cutting wave, kodwa yenza isihloko se-peak sibe yindilinga. Yilokhu esivame ukukubiza ngokuthi iziqongo zokugunda eziguquguqukayo. Ngemva kwe-transistor power amplifier endaweni yokulayisha ngokweqile, ukuphambuka okungeyona i-linear kwanda ngokushesha, okukhiqiza ukusika okukhulu kwe-wave esignalini. Ayenzi i-peak ibe yindilinga, kodwa iyayihlanza kahle. Abanye abantu basebenzisa i-compound impedance yokumelana, i-inductance kanye ne-capacitance ukulingisa i-loudspeaker, futhi bahlole ikhono langempela lokukhipha lezinhlobo eziningana ze-transistor power amplifier ezisezingeni eliphezulu. Imiphumela ikhombisa ukuthi lapho umthwalo une-phase shift, kuba ne-power amplifier engu-100W, futhi amandla okukhipha angempela angama-5W kuphela lapho ukuphambuka kungu-1%! Ngakho-ke, ukukhethwa kwenani eligciniwe le-transistor power amplifier:
I-amplifier yokuthembeka okuphezulu: izikhathi eziyi-10
Isikhulisi samandla sezinga eliphezulu se-Civil: izikhathi ezingu-6
I-amplifier yamandla aphakathi nendawo: izikhathi ezi-3 izikhathi ezi-4
I-amplifier yamandla eshubhu ingaba yincane kakhulu kunesilinganiso esingenhla.
3. Kufanele kushiywe imajini engakanani ezingeni elimaphakathi lokucindezela komsindo kanye nezinga eliphezulu lokucindezela komsindo ohlelweni. Kufanele kuncike kokuqukethwe kanye nendawo yokusebenza yohlelo lokusakaza. Lokhu okungenani okungu-10dB okungadingeki, kumculo we-pop wesimanje, ukugxuma kwe-bungee kanye neminye umculo, kudinga ukushiya ukuphindaphinda okungu-20 ~ 25dB, ukuze uhlelo lomsindo lusebenze ngokuphepha nangokuqhubekayo.
