Paunenge uchiridza mimhanzi, zvakaoma kuvhara ma frequency mabhendi nemukurukuri mumwe chete nekuda kwesimba uye zvimiro zvemutauri. "Iyo iri kunze kwefrequency mhinduro yeyuniti ichakanganisa kudzoreredza kwechiratidzo mune yakajairika frequency bhendi, uye inogona kukuvadza iyo tweeter uye yepakati-frequency.Naizvozvo, vagadziri vanofanirwa kupatsanura odhiyo frequency bhendi muzvikamu zvinoverengeka uye kushandisa vatauri vakasiyana kuridza akasiyana mabhendi.Iyi ndiyo mavambo uye basa re crossover.

Thecrossoverihwowo "uropi" hwemukurukuri, iyo inoita basa rinokosha muhutano hwemhando yezwi.Iyo crossover "brains" mumatauriri eamplifier yakakosha kune ruzha rwemhando.Audio kubuda kubva kune simba amplifier.Inofanirwa kugadziridzwa nezvikamu zvesefa mucrossover kuti zvibvumire masaini emamwe mafrequency echikamu chimwe nechimwe kupfuura.Naizvozvo, chete nesainzi uye zvine hungwaru dhizaini crossover yemukurukuri inogona kugadziridzwa maitiro akasiyana ezvikamu zvemukurukuri uye musanganiswa wakagadziridzwa kuita vatauri.Sunungura iyo yakanyanya kugona, ichiita kuti frequency yekupindura yega yega frequency bhendi ipfave uye chikamu chemufananidzo wekurira chakarurama.

Kubva pamusimboti wekushanda, iyo crossover ndeye sefa network inoumbwa ne capacitors uye inductors.Iyo treble chiteshi inongopfuura yakakwira-frequency masaini uye inovhara yakaderera-frequency masaini;iyo bass chiteshi inopesana neye treble chiteshi;iyo yepakati-renji chiteshi ibhendi-pass sefa iyo inogona kungopfuura frequencies pakati peiyo mbiri crossover point, imwe yakaderera uye imwe yakakwirira.

Izvo zvikamu zve passive crossover inoumbwa neL / C / R, kureva, L inductor, C capacitor, uye R resistor.Pakati pavo, L inductance.Hunhu hwunovharisa mafrequency epamusoro, chero bedzi iyo yakaderera frequencies ichipfuura, saka inonziwo low-pass filter;maitiro eC capacitor anongopesana neiyo inductance;iyo R resistor haina hunhu hwekucheka frequency, asi yakanangwa kune yakatarwa frequency mapoinzi uye Iyo frequency bhendi inoshandiswa kugadzirisa, yakaenzana curve, uye senitivity kuwedzera uye kuderera.

Hunhu hwe apassive crossover inzvimbo yakaoma yakawanda-yepamusoro-pasi uye yakaderera-pasi sefa masekete.Passive crossovers anoita kunge ari nyore, ane akasiyana magadzirirwo uye maitiro ekugadzira.Ichaita kuti crossover ibudise zvakasiyana-siyana muvatauri.
