Isigaba somsindo esisebenzayo sibizwa nangokuthi isigaba semvamisa esisebenzayo. Kungukuthi isiginali yomsindo womgcini ihlukaniswe engxenyeni ephakathi yokucubungula umgcini ngaphambi kokukhuliswa yi-Power Amplifier Circtuit. Umgomo ukuthi isiginali yomsindo sithunyelwa kwiyunithi ephakathi nendawo (i-CPU) yomgcini, futhi iyunithi eliphakathi nendawo lesiginali eliphakeme kakhulu lihlukaniswe ngesiginali yokuphendula okuphansi, bese kuthi izibonakaliso ezimbili ezihlukaniswe zifakwa ekukhuliseni nasekukhuliseni ngokwengeziwe. Indlela yokuhlukaniswa imvamisa iyidijithali.

I-Passive Sound Division, okubizwa nangokuthi i-Passive Frequency Division, ukuthi isiginali yomsindo ikhuliswe yi-Power Amplifier Circuit bese ihlukaniswa yi-crossover ebonakalayo bese ihlukaniswa yi-trossover ephambene, bese ifaka ku-tweeter noma woofer okuhambisanayo. Umgomo ukuthi umsindo wemvamisa ophakeme uhlungwa umjikelezo we-intanethi, ushiye imvamisa ephansi, bese ufaka umsindo ophansi ophansi ku-woofer. Umsindo we-Low-Frequency uhlungwa yi-electrolytic capacitor kanye nomsindo wemvamisa ephezulu kwesokunxele, bese kufakwa ku-tweeter. Indlela yokuhlukaniswa imvamisa ilungiswe yi-prostior eguquguqukayo.

Isigaba se-Active Sound kufanele kube yiyunithi enkulu enomsebenzi wokuhlukaniswa imvamisa noma engeza i-Digital esebenzayo esebenzayo ngemuva kokukhishwa komsindo weyunithi enkulu. Ngokuvamile, amamodeli aphezulu okuphela kwe-Alpine Main Unit anomsebenzi wokuhlukaniswa imvamisa. Ibonakala ngamaphuzu anembile we-Crossover kanye ne-Frequency Division. Umsindo uhlanzekile ngemuva kokuhlukaniswa imvamisa.

Amazwi asebenzayo asetshenziswa ngabantu abaningi. Amazwi amancane ama-WALKMAN asebenza ngamazwi asebenzayo, okungukuthi, iqoqo lama-amplifiers angezwa ebhokisini le-LientialsPeaker elijwayelekile. Lapho sifuna ukuyisebenzisa, sidinga kuphela isigaba sangaphambili hhayi isigaba sangemuva. I-Active yangaphakathi isebenzisa indlela yokuhlukaniswa ngomsindo kagesi, futhi isusa inkathazo yokufanisa nesigaba esifanele esingemuva; I-Passive LightsPeaker iyi-modispeaker ejwayelekile enezinto zokusebenzisa inethiwekhi eyodwa kuphela ngaphakathi.

Isiteji sangaphambili esisebenzayo yisigaba sangaphambili se-IC, transtoror, kanye neshubhu le-vacuum esivame ukubona. Inomphumela owengeziwe lapho isinali lifakwa bese kukhishwa khona. Lolu hlobo lwesigaba sangaphambili lungasebenzisa ukusebenza okunamandla okuphezulu, futhi izici zemodeli ngayinye nazo zihlukile. Isiteji sangaphambili se-Passive simane nje siyinto yokulawula ivolumu, ukuphuma kwaso kuzoba mncane kunokufakwa, kepha ithoni enikeza isimo ayincane, imvamisa umehluko omncane kuphela, hhayi ukuthi i-amplifier engaphambili esebenzayo ihluke kakhulu.
