Thaum ua nkauj nkauj, nws yog ib qho nyuaj rau npog txhua zaus bands nrog tsuas yog muaj kev txwv rau lub peev xwm thiab tej zaum yuav muaj kev cuam tshuam nrog lub zog thiab tej zaum tseem yuav ua rau lub sijhawm ua kom zoo dua qub Yog li ntawd, cov neeg tsim qauv yuav tsum faib cov sudio zaus band rau ntau seem thiab siv cov neeg sib txawv los ua si ntau zaus. Qhov no yog keeb kwm thiab ua haujlwm ntawm cov crossover.

Tuscrnyiaj txiagKuj yog "lub hlwb" ntawm tus hais lus, uas ua si lub luag haujlwm tseem ceeb hauv qhov zoo ntawm lub suab zoo. Cov crossover "lub hlwb" nyob rau hauv lub amplifier hais lus yog qhov tseem ceeb rau lub suab zoo. Suab tawm los ntawm lub hwj chim ua kom nrov dua. Nws yuav tsum tau ua los ntawm cov taub lim hauv cov crossover kom tso cai rau cov cim ntawm qee qhov chaw kom dhau. Yog li ntawd, tsuas yog los ntawm kev tshawb fawb thiab rationally tsim tus neeg hais lus hla kev tuaj yeem hloov pauv tau zoo thiab ua kom zoo rau cov neeg hais lus. Unleash lub peev xwm siab tshaj plaws, ua cov kev teb ntau ntawm txhua zaus band ntawm txhua lub suab du thiab lub suab hom muaj tseeb.

Los ntawm lub ntsiab cai ua haujlwm, cov txheej txheem txheej txheem yog lub tshuab lim uas muaj kev tsim cov khoom lag luam thiab cov inductors. Cov treleble channel tsuas yog dhau ntawm cov teeb tsa siab-zaus thiab cov cim qis zaus; Cov ntses hluav taws xob yog qhov sib txawv ntawm cov trreble channel; Lub sijhawm nruab nrab-taws yog ib qho band-dhau lim uas muaj peev xwm tsuas zaus dhau ntawm ob qho kev hla hla, ib qho qis thiab ib qho siab.

Cov Cheebtsam ntawm Crosser passover yog tsim ntawm L / C / R, uas yog, L indostror, ​​C Mroasitor, thiab R resistor. Ntawm lawv, L induction. Tus yam ntxwv yog los thaiv cov nquag nquag, ntev npaum li cov hauv qab qis dua, yog li nws tseem hu ua cov lim dej qis; Cov yam ntxwv ntawm C Capritor yog tsuas yog qhov fab ntxeev ntawm kev ua txhaum; Tus Resistor tsis muaj tus yam ntxwv ntawm kev txiav tej zaus, tab sis yog tsom rau cov ntsiab lus tshwj xeeb thiab kev nkhaus, thiab kev sib txig sib luag thiab txo qis.

Lub ntsiab lus ntawm apassive crossover yog ib txoj kev nyuaj ntawm ntau-pass thiab back-pass lim voj voog. Passive crossitive zoo li yooj yim, nrog cov qauv sib txawv thiab cov txheej txheem ntau lawm. Nws yuav ua cov txheej txheem txheej txheem ua rau cov neeg hais lus sib txawv.
