Paunenge uchiridza mimhanzi, zvakaoma kufukidza mabhendi ese emafrequency nespika imwe chete nekuda kwesimba uye zvipingamupinyi zvemutauri. Kana bhendi rese remafrequency rikatumirwa zvakananga kutweeter, mid-frequency, uye woofer, "signal yakawandisa" iri kunze kwemhinduro yemafrequency yeyuniti ichakanganisa kudzoreredzwa kwemasaini mubhendi remafrequency rakajairika, uye inogona kutokuvadza tweeter nemid-frequency. Naizvozvo, vagadziri vanofanirwa kupatsanura bhendi remafrequency ekuteerera kuita zvikamu zvakati wandei uye kushandisa masipika akasiyana kutamba mabhendi akasiyana emafrequency. Aya ndiwo mavambo nebasa recrossover.

Iyocrossoverzvakare "pfungwa" dzemutauri, izvo zvinoita basa rakakosha mukunaka kweruzha. "Uropi" hwecrossover mumaspika eamplifier hunokosha pamhando yeruzha. Kubuda kweaudio kubva kuamplifier yesimba. Inofanira kugadziriswa nezvikamu zvefirita mucrossover kuti zviratidzo zvemafrequencies chaiwo eyuniti yega yega zvipfuure. Saka, chete nekugadzira crossover yemutauri nenzira yesainzi uye ine musoro ndipo panogona kugadziriswa hunhu hwakasiyana hwemayuniti emutauri zvinobudirira uye musanganiswa wacho ugadziriswe kuti maspika aite zvakanaka. Bvisa mukana wepamusoro, zvichiita kuti mhinduro yefrequency yebhendi yega yega yefrequency ive yakatsetseka uye chikamu chemufananidzo weruzha chive chakarurama.

Kubva pakushanda kwayo, crossover ine network yekusefa ine ma capacitors nema inductors. Nzira ye treble inongopfuura masaini e high-frequency chete uye inovhara masaini e low-frequency; nzira ye bass inopesana ne treble channel; nzira yepakati i filter ye band-pass inogona kungopfuura ma frequency pakati pema crossover points maviri, imwe yakaderera neimwe yakakwirira.

Zvikamu zvepassive crossover zvinoumbwa neL/C/R, kureva L inductor, C capacitor, uye R resistor. Pakati pazvo, L inductance. Hunhu hwacho ndehwekuvharira mafrequency akakwira, chero bedzi mafrequency akaderera achipfuura, saka inonziwo low-pass filter; hunhu hweC capacitor hwakangopesana neinductance; R resistor haina hunhu hwekucheka mafrequency, asi yakanangwa pane chaiwo mafrequency points uye Frequency band inoshandiswa kugadzirisa, equalization curve, uye sensitivity inowedzera uye inoderera.

Chinangwa chekuchinjika kusingashande imhando ye "high-pass" uye "low-pass" filter circuits dzakati wandei. "Passive crossovers" dzinoita sedzakapusa, dzine magadzirirwo akasiyana uye maitiro ekugadzira. Izvi zvinoita kuti "crossover" ibudise mhedzisiro dzakasiyana mumaspika.
