Mu gihe ucuranga umuziki, biragoye gupfundikira imirongo yose y'amajwi ukoresheje indangururamajwi imwe gusa bitewe n'ubushobozi n'imiterere y'indangururamajwi. Iyo umurongo wose w'amajwi woherejwe kuri tweeter, frequency yo hagati, na woofer, "ikimenyetso cy'ikirenga" kiri hanze y'umuvuduko w'amajwi w'igikoresho kizagira ingaruka mbi ku kugaruka kw'amajwi mu gice gisanzwe cy'amajwi, ndetse gishobora no kwangiza tweeter na frequency yo hagati. Kubwibyo, abashushanya bagomba kugabanya umurongo w'amajwi mo ibice byinshi kandi bagakoresha indangururamajwi zitandukanye kugira ngo bacure imirongo itandukanye y'amajwi. Iyi ni yo nkomoko n'imikorere y'umurongo w'amajwi.

Itsindacrossoverni na "ubwonko" bw'indangururamajwi, bugira uruhare runini mu bwiza bw'amajwi. "Ubwonko" bwo mu ndangururamajwi mu ndangururamajwi ni ingenzi ku bwiza bw'amajwi. Amajwi asohoka mu ndangururamajwi. Agomba gutunganywa n'ibice by'urufunguzo biri mu nzirangururamajwi kugira ngo ibimenyetso by'imirongo yihariye ya buri gice bitambuke. Kubwibyo, ni mu buryo bwa siyansi kandi bushyize mu gaciro gusa imiterere itandukanye y'indangururamajwi ishobora guhindurwa neza no guhuza neza kugira ngo indangururamajwi zikore neza. Kuramo ubushobozi ntarengwa, bigatuma igisubizo cya buri murongo w'indangururamajwi kigenda neza kandi ishusho y'amajwi ikaba nziza.

Ukurikije ihame ry'imikorere, crossover ni urusobe rw'amajwi rugizwe na capacitors na inductors. Umuyoboro wa treble unyuza gusa ibimenyetso bya frequency yo hejuru kandi ugafunga ibimenyetso bya frequency yo hasi; umuyoboro wa bass unyuranyije n'umuyoboro wa treble; umuyoboro wo hagati ni filter ya band-pass ishobora gusa kwambutsa frequency hagati y'ingingo ebyiri za crossover, imwe iri hasi n'indi iri hejuru.

Ibice bigize crossover idafite ingufu bigizwe na L/C/R, ni ukuvuga L inductor, C capacitor, na R resistor. Muri byo harimo L inductance. Ikiranga ni ugufunga frequencies zo hejuru, igihe cyose frequencies zo hasi zirenze, bityo byitwa low-pass filter; imiterere ya C capacitor inyuranye gusa n'inductance; R resistor ntabwo ifite umwihariko wo gukata frequencies, ahubwo igamije ahantu runaka ha frequencies kandi frequencies band ikoreshwa mu gukosora, gupima curve, no kwiyongera no kugabanuka kw'ubushobozi bwo kumva.

Ishingiro ry'ikintuguhurira hamwe mu buryo butizewe ni urusobe rw'imiyoboro myinshi ikoresha ikoranabuhanga rya "high-pass" n'ikoresha ikoranabuhanga rya "low-pass". Imiyoboro ikoresha ikoranabuhanga rya "passive crossover" isa nkaho yoroshye, ifite imiterere itandukanye n'uburyo bwo kuyikora. Izatuma ikoranabuhanga ritanga ingaruka zitandukanye mu ndangururamajwi.
