I ka wā e pāʻani ai i ke mele, paʻakikī ke uhi ʻana i nā kaha alapine a pau me hoʻokahi wale nō mea haʻiʻōlelo ma muli o ka hiki a me nā palena o ke kūkulu ʻia ʻana o ka mea haʻiʻōlelo. No laila, pono nā mea hoʻolālā e hoʻokaʻawale i ke kāʻei alapine leo i mau ʻāpana a hoʻohana i nā mea ʻōlelo like ʻole e pāʻani i nā ʻāpana alapine like ʻole. ʻO kēia ke kumu a me ka hana o ka crossover.

ʻO kacrosoverʻo ia hoʻi ka "lolo" o ka mea haʻiʻōlelo, kahi mea nui i ka maikaʻi o ka maikaʻi o ke kani. He mea koʻikoʻi ka "lolo" crossover i loko o nā mea leo hoʻonui i ka maikaʻi o ke kani. Puke leo mai ka mana hoʻonui. Pono e hana ʻia e nā ʻāpana kānana i loko o ka crossover e ʻae i nā hōʻailona o nā alapine kikoʻī o kēlā me kēia ʻāpana e hele. No laila, ma ka hoʻolālā ʻepekema a me ka noʻonoʻo pono ʻana i ka crossover e hiki ai ke hoʻololi maikaʻi ʻia nā ʻano like ʻole o nā ʻāpana leo a hoʻoponopono ʻia ka hui ʻana e hana i nā mea haʻiʻōlelo. E hoʻokuʻu i ka mea hiki ke loaʻa, e hoʻomaʻamaʻa i ka pane alapine o kēlā me kēia alapine alapine a pololei ka pae kiʻi kani.

Mai ke kumu hana, ʻo ka crossover kahi kānana kānana i haku ʻia me nā capacitors a me nā inductors. ʻO ke kahawai treble wale nō ke hele i nā hōʻailona alapine kiʻekiʻe a poloka i nā hōʻailona haʻahaʻa; ʻo ke kahawai bass ka mea kū'ē i ke kahawai treble; ʻO ke kahawai waena waena he kānana band-pass e hiki ke hele i nā alapine wale nō ma waena o nā kiko kea ʻelua, hoʻokahi haʻahaʻa a hoʻokahi kiʻekiʻe.

ʻO nā ʻāpana o ka crossover passive i haku ʻia me L / C / R, ʻo ia hoʻi, L inductor, C capacitor, a me R resistor. I waena o lākou, L inductance. ʻO ka hiʻohiʻona ka pale ʻana i nā alapine kiʻekiʻe, ʻoiai ka lōʻihi o ka hala ʻana o nā alapine haʻahaʻa, no laila ua kapa ʻia ʻo ia he kānana haʻahaʻa; ʻO nā hiʻohiʻona o ka capacitor C ke kū'ē wale i ka inductance; ʻAʻole i loaʻa i ka R resistor ke ʻano o ka ʻoki alapine, akā ua kuhikuhi ʻia i nā kiko alapine kikoʻī a hoʻohana ʻia ka band frequency no ka hoʻoponopono ʻana, ka pihi hoʻohālikelike, a me ka hoʻonui a me ka emi ʻana o ka naʻau.

ʻO ke kumu o ahoʻopaʻa paʻa he paʻakikī o kekahi mau kaapuni kānana kiʻekiʻe a me ka ala haʻahaʻa. He mea maʻalahi nā crossovers passive, me nā hoʻolālā like ʻole a me nā kaʻina hana. E hana ia i ka crossover i nā hopena like ʻole i nā mea haʻi'ōlelo.
