Chipangizo chomwe chimagawa ma audio signals ofooka m'ma frequency osiyanasiyana, omwe ali patsogolo pa power amplifier. Pambuyo pa kugawa, ma power amplifier odziyimira pawokha amagwiritsidwa ntchito kukulitsa chizindikiro chilichonse cha audio frequency band ndikuchitumiza ku speaker unit yofanana. Zosavuta kusintha, kuchepetsa kutaya mphamvu ndi kusokoneza pakati pa ma speaker units. Izi zimachepetsa kutaya kwa ma signal ndikukweza mtundu wa mawu. Koma njira iyi imafuna ma power amplifier odziyimira pawokha pa circuit iliyonse, yomwe ndi yokwera mtengo komanso yokhala ndi circuit yovuta. Makamaka pamakina omwe ali ndi subwoofer yodziyimira pawokha, ma electronic frequency dividers ayenera kugwiritsidwa ntchito kusiyanitsa chizindikiro ndi subwoofer ndikutumiza ku subwoofer amplifier.

DAP-3060III 3 mu 6 kunja kwa purosesa ya digito ya audio

Kuphatikiza apo, pali chipangizo chotchedwa digito audio processor chomwe chili pamsika, chomwe chingathenso kugwira ntchito monga equalizer, voltage limiter, frequency divider, ndi delayer. Pambuyo poti chizindikiro cha analog chopangidwa ndi analog mixer chalowetsedwa mu purosesa, chimasinthidwa kukhala chizindikiro cha digito ndi chipangizo chosinthira AD, kukonzedwa kenako nkusinthidwa kukhala chizindikiro cha analog ndi DA converter kuti chitumizidwe ku amplifier yamagetsi. Chifukwa chogwiritsa ntchito digito processing, kusinthako kumakhala kolondola kwambiri ndipo chiwerengero cha phokoso chimakhala chotsika. Kuphatikiza pa ntchito zomwe zakwaniritsidwa ndi equalizers zodziyimira pawokha, voltage limiters, frequency dividers, ndi delayers, digital input gain control, phase control, ndi zina zotero zawonjezedwanso, zomwe zimapangitsa kuti ntchitozo zikhale zamphamvu kwambiri.
