Ko te wehenga oro hohe e kiia ana ko te wehenga auau hohe. Ko te wehenga oro o te kaihautū ko te wehenga auau oro i roto i te wae tukatuka matua o te kaihautū i mua i te whakanuia e te ara iahiko whakakaha mana. Ko te kaupapa matua ko te tuku i te tohu oro ki te wae tukatuka matua (CPU) o te kaihautū, ā, ko te wae tukatuka matua o te tohu oro kaihautū ka wehea ki te tohu auau-iti me te tohu auau-tiketike e ai ki te awhe urupare auau, kātahi ka whakaurua ngā tohu e rua kua wehea ki roto i te ara iahiko whakanui, ā, ka whakanuia motuhaketia. Ko te tikanga wehenga auau he matihiko.

Ko te wehenga oro korekore, e kiia ana hoki ko te wehenga auau korekore, ko te whakanui i te tohu oro e te ara iahiko whakakaha mana, kātahi ka wehea e te whakawhiti korekore, kātahi ka whakaurua ki te tweeter, ki te woofer rānei e rite ana. Ko te kaupapa matua ko te tātari i te oro auau teitei e te ara iahiko whakaawe, ka waiho te oro auau iti, kātahi ka whakauru i te oro auau iti ki te woofer. Ka tātarihia te oro auau iti e te pūnga hiko, ā, ka waiho te oro auau teitei, kātahi ka whakaurua ki te tweeter. Ka whakatikatikaina te tikanga wehenga auau e te ātete taurangi.

Me noho te wehenga oro hohe hei wae matua me te mahi wehenga auau hohe, me tāpiri rānei he whakawhiti mamati hohe i muri i te putanga oro o te wae matua. Ko te tikanga, ko ngā tauira teitei o te wae matua Alpine he mahi wehenga auau hohe. Ko tōna āhuatanga he tohu whakawhiti tika me te wehenga auau. He ma te oro i muri i te wehenga auau.

He tokomaha ngā tāngata e whakamahi ana i ngā pūorooro kaha. Ko ngā pūorooro iti o te Walkman he pūorooro kaha, arā, he huinga whakakaha e tāpirihia ana ki te pouaka pūorooro whānui. Ina hiahia tātou ki te whakamahi, ko te atamira o mua anake te mea e hiahiatia ana, kaua ko te atamira o muri. Ka whakamahia e te pūorooro o roto he tikanga wehewehe oro hiko, ā, ka kore e raru te taurite ki te atamira o muri e tika ana; ko te pūorooro kore mahi he pūorooro whānui me te whatunga whakawhiti kotahi anake i roto.

Ko te atamira mua hohe ko te atamira mua o te IC, te transistor, me te ngongo korehau e kitea whānuitia ana e tātou. He pānga whakakaha tōna ina whakaurua te tohu, kātahi ka tukuna. Ka taea e tēnei momo atamira mua te whakaatu i te mahi hihiri teitei, ā, he rerekē hoki ngā āhuatanga o ia tauira. Ko te atamira mua kore hohe he whakaiti whakahaere oro noa iho, ka iti ake tōna putanga i te whakaurunga, engari he iti ake te āhua o te whakaputa oro, he iti noa te rerekētanga i te nuinga o te wā, he rerekē rawa atu i te whakakaha atamira mua hohe.
