Ko te wehenga oro kaha e kiia ana ko te wehenga auau kaha.Ko te tohu ororongo o te kaihautu ka wehewehea i roto i te waahanga tukatuka pokapū o te ope i mua i te whakanuihia e te hiko hiko hiko.Ko te kaupapa ko te tohu ororongo ka tukuna ki te waahanga tukatuka pokapū (CPU) o te kaihautu, ka wehewehea te waahanga tukatuka pokapū o te tohu oro oro oro ki te tohu iti-auau me te tohu teitei-nui e ai ki te awhe whakautu auau, katahi ka whakauruhia nga tohu wehe e rua ki roto i te ara iahiko whakakaha, ka whakanuia wehea.Ko te tikanga wehenga auau he matihiko.

Ko te wehenga oro hāngū, e kīia ana ko te wehenga auau hāngū, ko te tohu oro e whakanuia ana e te iahiko whakakaha kaha ka wehea e te whiti whakawhiti, katahi ka uru ki te tweeter, ki te woofer ranei.Ko te maataapono ko te oro auau teitei ka tātarihia e te ara iahiko inductance, ka waiho te oro auau iti, katahi ka whakauru i te oro iti-auau ki te woofer.Ko te oro iti-auau ka tātarihia e te hikohiko hiko ka waiho te oro teitei, katahi ka whakauruhia ki te tweeter.Ko te tikanga wehenga auau ka whakatikahia e te parenga taurangi.

Ko te wehenga oro kaha ko te waahanga matua me te mahi wehenga auau hohe, ka taapirihia ranei he whakawhiti kaha mamati i muri i te putanga oro o te waahanga matua.Ko te tikanga, ko nga tauira teitei o te waahanga matua o Alpine he mahi wehenga auau kaha.Kei te tohuhia e nga tohu whakawhiti tika me te wehenga auau.He ma te tangi i muri i te wehenga auau.

He maha nga tangata e whakamahi ana i nga ororongo kaha.Ko nga kaikorero iti o te Walkman he kaikorero kaha, ara, ka taapirihia he huinga orooro ki te pouaka orooro whanui.Ina hiahia ana tatou ki te whakamahi, ko te atamira o mua anake ka hiahia, kaua ko te atamira o muri.Ko te mahi o roto e whakamahi ana i te tikanga wehenga oro hiko, me te whakakore i te raru o te taurite ki te atamira o muri e tika ana;te tukuoro hāngū he pūoro whānui kotahi anake te whatunga whakawhiti i roto.

Ko te atamira o mua ko te atamira o mua o te IC, transistor, me te ngongo korehau e kitea ana e tatou.He kaha whakakaha i te wa e uru ana te tohu katahi ka puta.Ka taea e tenei ahua o te atamira o mua te kaha ki te mahi hihiri, me nga ahuatanga o ia tauira he rereke ano nga taera.Ko te atamira o mua o mua he attenuator mana oro, ka iti ake te putanga mai i te whakaurunga, engari he iti ake te ahuatanga o te reo, he iti noa te rereketanga, kaore i rite ki te whakakaha o te atamira o mua he tino rereke.
