Ha u bapala 'mino, ho thata ho koahela lihlopha tsohle tsa maqhubu ka sebui se le seng feela ka lebaka la bokhoni le mefokolo ea sebopeho sa sebui. Ka hona, baqapi ba tlameha ho arola sehlopha sa maqhubu a molumo ka likarolo tse 'maloa mme ba sebelise libui tse fapaneng ho bapala lihlopha tse fapaneng tsa maqhubu. Ena ke tšimoloho le mosebetsi oa crossover.

Thecrossoverhape ke “boko” ba sebui, bo phethang karolo ea bohlokoa boleng ba molumo. "Boko" ba crossover ho libui tsa amplifier bo bohlokoa ho boleng ba molumo. Phatlalatso ea molumo ho tsoa ho amplifier ea matla. E tlameha ho sebetsoa ke likarolo tsa filthara ho crossover ho lumella matšoao a maqhubu a ikhethileng a yuniti ka 'ngoe hore a fete. Ka hona, ke feela ka ho rala crossover ea mahlale le ka mokhoa o utloahalang, litšobotsi tse fapaneng tsa likarolo tsa sebui li ka fetoloa hantle 'me motsoako oa ntlafatsoa ho etsa libui. Tlosa bokhoni bo boholo, ho etsa hore karabelo ea khafetsa ea sehlopha se seng le se seng sa maqhubu a be bonolo le karolo ea setšoantšo sa molumo e nepahale.

Ho latela molao-motheo oa ts'ebetso, crossover ke marang-rang a filthara a entsoeng ka li-capacitor le li-inductors. Mocha oa treble o fetisa mats'oao a maqhubu a phahameng feela mme o thibela mats'oao a maqhubu a tlase; mocha oa bass o fapane le mocha oa treble; mocha o bohareng ke sefahla sa li-band-pass se ka fetisang maqhubu pakeng tsa lintlha tse peli tsa crossover, e 'ngoe e tlaase le e phahameng.

Likarolo tsa crossover ea passive li entsoe ka L / C / R, ke hore, L inductor, C capacitor, le R resistor. Har'a bona, L inductance. Tšobotsi ke ho thibela maqhubu a phahameng, hafeela maqhubu a tlaase a feta, kahoo e boetse e bitsoa "low-pass filter"; litšoaneleho tsa C capacitor li fapane feela le inductance; R resistor ha e na tšobotsi ea ho itšeha khafetsa, empa e lebisitsoe ho lintlha tse itseng tsa maqhubu 'me The frequency band e sebelisoa bakeng sa ho lokisa, ho lekanngoa curve, le ho eketseha ha kutloisiso le ho fokotseha.

Taba ea mantlha ea apassive crossover ke motsoako oa li-circuits tse 'maloa tse phahameng le tse tlaase. Li-crossovers tsa passive li bonahala li le bonolo, ka meralo e fapaneng le mekhoa ea tlhahiso. E tla etsa hore crossover e hlahise liphello tse fapaneng ho libui.
