Ungayicwangcisa njani i-amplifier yenkqubo ye-line array?

1, Impedance kufuneka ihambelane

Ukudibanisa i-Impedance kubhekisa kwinto yokuba i-rate rated output impedance ye-power amplifier kufuneka ihambelane ne-rate rated impedance yesithethi se-line array. I-output impedance ye-amplifier eqhelekileyo ixhasa i-8 Ω kunye ne-4 Ω, ngelixa ezinye ii-amplifier zixhasa i-2 Ω. Izithethi ze-line array zihlala zine-output impedance ukusuka kwi-16 Ω ukuya kwi-8 Ω. Ukuba izithethi ezimbini ze-line array ziqhagamshelwe ngaxeshanye kwitshaneli, i-impedance yesithethi se-line array ye-16 Ω iya kuba yi-8 Ω, njalo njalo. Ke ngoko, i-output impedance kunye nenani loqhagamshelo oluhambelanayo lwesithethi se-line array kufuneka luhambelane ne-output impedance ye-power amplifier.

2, Amandla kufuneka afane

Umgangatho othile wokwabiwa kwamandla ee-amplifiers zamandla kunye nezithethi ze-line array kukuba phantsi kweemeko ezithile ze-impedance, amandla alinganisiweyo e-power amplifier kufuneka abe mkhulu kunamandla alinganisiweyo ezithethi ze-line array. Amandla alinganisiweyo e-power amplifier kwiindawo zokukhulisa iinkomfa kufuneka abe yi-1.2-1.5 ngokuphindwe kayi-speakers ze-line array. Ukuba yimeko eneziphumo ezinkulu ezitshintshayo, amandla alinganisiweyo kufuneka abe yi-1.5-2 ngokuphindwe kayi-speakers ze-line array. Ngokulandela lo mgangatho wokumisela, kunokwenzeka ukuqinisekisa ukuba i-amplifier isebenza kwimeko yayo efanelekileyo ngelixa ikwaqinisekisa ukhuseleko lwesithethi se-line array.
