Ukuhlukaniswa komsindo okusebenzayo kubizwa nangokuthi ukuhlukaniswa kwemvamisa esebenzayo. Kungukuthi isignali yomsindo yesikhungo ihlukaniswe kuyunithi yokucubungula ephakathi yesikhungo ngaphambi kokuba ikhuliswe yisekethe ye-amplifier yamandla. Umgomo uwukuthi isignali yomsindo ithunyelwa kuyunithi yokucubungula ephakathi (i-CPU) yesikhungo, kanti iyunithi yokucubungula ephakathi yesignali yomsindo yesikhungo ihlukaniswe ibe isignali yemvamisa ephansi kanye nesignali yemvamisa ephezulu ngokwebanga lokuphendula kwemvamisa, bese kuthi izimpawu ezimbili ezihlukanisiwe zifakwe kusekethe yokukhulisa futhi zikhuliswe ngokwehlukana. Indlela yokuhlukanisa imvamisa idijithali.

Ukuhlukaniswa komsindo ongasebenzi, okubizwa nangokuthi ukuhlukaniswa kwemvamisa engasebenzi, ukuthi isignali yomsindo ikhuliswa yisekethe ye-amplifier yamandla bese ihlukaniswa yi-crossover engasebenzi, bese ifakwa kwi-tweeter noma i-woofer ehambisanayo. Umgomo uwukuthi umsindo wemvamisa ephezulu uhlungwa yisekethe ye-inductance, kushiye umsindo wemvamisa ephansi, bese kufakwa umsindo wemvamisa ephansi ku-woofer. Umsindo wemvamisa ephansi uhlungwa yi-capacitor ye-electrolytic bese kushiywa umsindo wemvamisa ephezulu, bese kuba ukufakwa kwi-tweeter. Indlela yokuhlukaniswa kwemvamisa ilungiswa yi-resistor eguquguqukayo.

Ukuhlukaniswa komsindo okusebenzayo kumele kube yiyunithi eyinhloko enomsebenzi wokuhlukaniswa kwemvamisa esebenzayo noma kufakwe i-digital active crossover ngemuva kokukhishwa komsindo kweyunithi eyinhloko. Ngokuvamile, amamodeli aphezulu eyunithi eyinhloko ye-Alpine anomsebenzi wokuhlukaniswa kwemvamisa esebenzayo. Ubonakala ngamaphuzu okuwela anembile kanye nokuhlukaniswa kwemvamisa. Umsindo uhlanzekile ngemva kokuhlukaniswa kwemvamisa.

Izipikha ezisebenza kahle empeleni zisetshenziswa abantu abaningi. Izipikha ezincane ze-Walkman ziyizipikha ezisebenza kahle, okungukuthi, isethi yama-amplifier ifakwa ebhokisini lesipikha esijwayelekile. Uma sifuna ukuyisebenzisa, sidinga kuphela isigaba sangaphambili hhayi isigaba sangemuva. I-active internal isebenzisa indlela yokuhlukanisa umsindo kagesi, futhi iqeda inkinga yokufanisa nesigaba sangemuva esifanele; isipikha esingasebenzi siyi-loudspeaker ejwayelekile enenethiwekhi eyodwa kuphela ye-crossover ngaphakathi.

Isigaba sangaphambili esisebenzayo yisigaba sangaphambili se-IC, i-transistor, kanye ne-vacuum tube esivame ukuyibona. Sinomphumela wokukhulisa lapho isignali ifakwa bese ikhishwa. Lolu hlobo lwesigaba sangaphambili lungasebenza kahle kakhulu, futhi izici zemodeli ngayinye nazo zihlukile nge-timbre. Isigaba sangaphambili esingasebenzi simane nje siyi-attenuator yokulawula ivolumu, umphumela waso uzoba mncane kunowokufaka, kodwa isimo sokunikeza ithoni sincane, ngokuvamile umehluko omncane kuphela, hhayi njenge-amplifier yesigaba sangaphambili esisebenzayo ehluke kakhulu.
