Ukuhlukaniswa komsindo okusebenzayo kubizwa nangokuthi i-active frequency division. Iwukuthi isignali yomsindo yomsingathi ihlukaniswa kuyunithi yokucubungula emaphakathi yomsingathi ngaphambi kokukhuliswa yisekethe yesikhulisi samandla. Isimiso siwukuthi isignali yomsindo ithunyelwa kuyunithi yokucubungula emaphakathi (CPU) yomsingathi, futhi iyunithi yokucubungula emaphakathi yesiginali yomsindo womsingathi ihlukaniswa isignali yefrikhwensi ephansi kanye nesignali yefrikhwensi ngokuya ngebanga lokuphendula imvamisa, bese amasignali amabili ahlukanisiwe afakwa kusekethe yokukhulisa futhi akhuliswe ngokuhlukana. Indlela yokuhlukanisa imvamisa iyidijithali.

I-Passive sound division, ebizwa nangokuthi i-passive frequency division, ukuthi isignali yomsindo ikhuliswa yisekethe ye-amplifier yamandla bese ihlukaniswa yi-passive crossover, bese ifaka ku-tweeter ehambisanayo noma i-woofer. Isimiso siwukuthi i-high frequency sound ihlungwa yi-inductance circuit, ishiya i-low frequency sound, bese ifaka umsindo we-low-frequency ku-woofer. Umsindo we-low-frequency uhlungwa yi-electrolytic capacitor futhi umsindo we-high-frequency ushiywe, bese ufakwa ku-tweeter. Indlela ye-frequency division ilungiswa nge-varistor resistor.

Ukuhlukaniswa komsindo osebenzayo kufanele kube iyunithi eyinhloko enomsebenzi wokuhlukanisa imvamisa esebenzayo noma wengeze i-digital active crossover ngemva kokuphuma komsindo kweyunithi enkulu. Ngokuvamile, amamodeli asezingeni eliphezulu eyunithi eyinhloko ye-Alpine anomsebenzi wokuhlukanisa imvamisa osebenzayo. Ibonakala ngamaphoyinti anembile we-crossover kanye nokuhlukaniswa kwama-frequency. Umsindo uhlanzekile ngemva kokuhlukaniswa kwamafrikhwensi.

Izipikha ezisebenzayo empeleni zisetshenziswa abantu abaningi. Izikhulisa-zwi ezincane ze-Walkman izikhulisa-zwi ezisebenzayo, okusho ukuthi, isethi yezikhulisa-zwi zengezwa ebhokisini lesikhulisazwi esijwayelekile. Uma sifuna ukuyisebenzisa, sidinga isiteji esingaphambili kuphela hhayi esangemuva. Ingaphakathi elisebenzayo lisebenzisa indlela yokuhlukanisa umsindo we-elekthronikhi, futhi iqeda inkinga yokumatanisa nesiteji sangemuva esifanele; isipikha sokwenziwa siyisipikha esijwayelekile esinohleloxhumano olulodwa kuphela ngaphakathi.

Isiteji sangaphambili esisebenzayo yisigaba sangaphambili se-IC, i-transistor, neshubhu lovacuum esivame ukulibona. Inomphumela okhulisayo lapho isignali ifakwa bese iphuma. Lolu hlobo lwesiteji sangaphambili lungasebenzisa ukusebenza okunamandla okuphezulu, futhi izici zemodeli ngayinye nazo ziyi-timbre ehlukile. Isiteji esingaphambili simane siyisifinyezo sokulawula ivolumu, okukhiphayo kuzoba kuncane kunokokufaka, kodwa isimo sokunikeza ithoni sincane, ngokuvamile umehluko omncane kuphela, akufani ne-amplifier yesiteji sangaphambili esisebenzayo sihluke kakhulu .
