Lapho udlala umculo, kunzima ukumboza wonke amabhande amvamisa ngesipika esisodwa ngenxa yokuthola umkhawulo we-tweeter. Ngakho-ke, abaklami kufanele bahlukanise ibhendi yemvamisa yomsindo zibe izingxenye eziningana futhi basebenzise izikhulumi ezahlukahlukene ukuthi badlale ama-band avamisile. Le yimvelaphi nomsebenzi we-crossover.

Le khasicrosporFuthi "ubuchopho" besipika, esidlala indima ebalulekile kwikhwalithi yekhwalithi yomsindo. I-Crossover "ubuchopho" kwizikhulumi ze-amplifier zibalulekile kwikhwalithi yomsindo. Ukukhishwa komsindo kusuka ku-amplifier yamandla. Kufanele kucutshungulwe yizinto zokuhlunga ezise-crossover ukuvumela amasiginali amafrikhwensi athile ophiko ngalunye adlule. Ngakho-ke, kuphela ngokwesayensi nangokwesayensi i-Crossover Crossover angaguqulwa ngayo ngezenzo ezahlukahlukene futhi inhlanganisela eyenziwe kahle ukwenza izikhulumi. Vula amandla amakhulu, okwenza ukuphendula imvamisa kwebhendi ngayinye yokuvama kanye nesigaba sezithombe zomsindo zinembile.

Ukusuka kwisimiso esisebenzayo, i-Crosrover inethiwekhi yokuhlunga eyakhiwa ama-capacitors kanye nabamangazayo. Isiteshi se-Treble sidlula amasiginali afinyelela kufriji eliphezulu kuphela futhi uvimbe amasiginali aphansi aphansi; Isiteshi seBass siphambene nesiteshi esishisayo; Isiteshi saphakathi nendawo siyisihlungi se-band-pass esikwazi ukudlula amaza phakathi kwamaphuzu amabili ase-crossoover, aphansi futhi aphezulu.

Izakhi ze-crossover ezingenangqondo zakhiwa i-L / C / R, okungukuthi, l inductor, c capacitor, kanye nokuphikiswa. Phakathi kwazo, ukungenelela. Isici sokuvimba amaza aphezulu, inqobo nje uma amafrikhwensi aphansi adlula, ngakho-ke kubizwa nangokuthi isihlungi esiphansi sokudlula; Izici ze-C Capacitor ziphambene nje nokuqanjwa; I-R Resistor ayinaso isimilo sokunciphisa imvamisa, kepha ihloselwe amaphuzu athile okuvama kanye nemvamisa ye-Frequency isetshenziselwa ukulungiswa, ukulingana kwejika, nokwanda kokuzwela nokuncipha.

Umnyombo weI-Passive Crossover kuyinkimbinkimbi yemijikelezo eminingana edlula ephezulu kanye ne-low-pass. Ama-crossover angenangqondo abonakala elula, anemiklamo ehlukene nezinqubo zokukhiqiza. Kuzokwenza i-crossover ikhiqize imiphumela ehlukile kwizikhulumi.
