Active phokoso kugawa amatchedwanso active frequency division.Ndikuti chizindikiro cha audio cha wolandirayo chimagawidwa m'chigawo chapakati chokonzekera cha wolandirayo chisanakulitsidwe ndi dera la amplifier mphamvu.Mfundoyi ndi yakuti chizindikiro cha audio chimatumizidwa ku central processing unit (CPU) ya wolandirayo, ndipo gawo lapakati lopangira ma audio audio limagawidwa kukhala siginecha yotsika kwambiri komanso yothamanga kwambiri malinga ndi momwe amayankhira pafupipafupi, ndiyeno zizindikiro ziwiri zolekanitsidwa zimalowetsedwa mu gawo lokulitsa ndikukulitsidwa padera.Njira yogawa ma frequency ndi digito.

Kugawikana kwa phokoso lopanda phokoso, komwe kumatchedwanso passive frequency division, ndikuti siginecha yomvera imakulitsidwa ndi gawo la amplifier mphamvu kenako ndikugawidwa ndi passive crossover, kenako ndikulowetsa ku tweeter kapena woofer.Mfundoyi ndi yakuti phokoso lapamwamba kwambiri limasefedwa ndi dera la inductance, kusiya phokoso laling'ono, kenako ndikulowetsa phokoso laling'ono ku woofer.Phokoso lotsika kwambiri limasefedwa ndi electrolytic capacitor ndipo phokoso lapamwamba limasiyidwa, kenako ndikulowetsa kwa tweeter.Njira yogawanitsa pafupipafupi imasinthidwa ndi resistor variable.

Kugawa kwa mawu kogwira kuyenera kukhala gawo lalikulu lokhala ndi gawo logawa pafupipafupi kapena kuwonjezera cholozera cholumikizira cha digito pambuyo potulutsa mawu agawo lalikulu.Nthawi zambiri, mitundu yapamwamba kwambiri ya Alpine main unit imakhala ndi ntchito yogawa pafupipafupi.Imadziwika ndi mfundo zolondola za crossover komanso kugawa pafupipafupi.Phokoso limakhala loyera pambuyo pakugawa pafupipafupi.

Zokuzira mawu zogwira ntchito zimagwiritsidwa ntchito ndi anthu ambiri.Zokweza mawu zing'onozing'ono za Walkman ndi zokuzira mawu zogwira ntchito, ndiye kuti, seti ya zokulirakulira zimawonjezedwa ku bokosi la zokuzira mawu.Tikafuna kugwiritsa ntchito, timangofunika siteji yakutsogolo osati kumbuyo.Zomwe zimagwiritsidwa ntchito mkati zimagwiritsa ntchito njira yogawanitsa phokoso lamagetsi, ndikuchotsa zovuta zofananira ndi gawo loyenera lakumbuyo;chowuzira cholumikizira ndi cholumikizira chamba chomwe chili ndi netiweki imodzi yokha mkati mwake.

Gawo lakutsogolo logwira ntchito ndi gawo lakutsogolo la IC, transistor, ndi vacuum chubu zomwe timaziwona nthawi zambiri.Zimakhala ndi mphamvu yokulitsa pamene chizindikirocho chikulowetsedwa ndikutuluka.Gawo lakutsogolo lamtunduwu limatha kukhala ndi magwiridwe antchito apamwamba, ndipo mawonekedwe amtundu uliwonse amasiyananso ndi timbre.Gawo lakutsogolo limangokhala chowongolera voliyumu, zotulutsa zake zimakhala zazing'ono kuposa zomwe zalowetsedwa, koma mawonekedwe operekera mamvekedwe amakhala ochepa, nthawi zambiri amangosiyana pang'ono, osati ngati amplifier yogwira yakutsogolo ndiyosiyana kwambiri.
