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 ku-central processing unit (CPU) yomsingathi, futhi iyunithi yokucubungula emaphakathi yesiginali yomsindo womsingathi ihlukaniswe isignali ye-low-frequency kanye nesignali ye-high-frequency ngokuya ngebanga lokuphendula imvamisa, bese amasiginali amabili ahlukanisiwe afakwa kusekethe yokukhulisa amandla futhi akhuliswe ngokwehlukana.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 .
