Zipangizo za Karaoke kuwonjezera pa okamba, zida zanyimbo ndizofunikira kwambiri, mtundu wa amplifier wokha ndiyofunikanso. Ntchito ya KTV iyenera kuphatikizidwa ndi kukula kwa chipinda chanu ndi zida zokongoletsera. Madera osiyanasiyana azipinda azigwiritsa ntchito zokulitsira mphamvu zamagetsi. Tcherani khutu pakufanana kwa mkuzamawu ndi wolankhulira.

Mphamvu yama amplifier ophatikizira a karaoke opangidwa koyambirira koyambirira amakhala ochepa, ndipo oyankhula amathandizira ndi omwe amalankhula zazing'ono zamagetsi okhala ndi chidwi chachikulu. Vuto lofala kwambiri ndikulira kwa mayankho. Cholinga chake ndikuti kusungidwa kwamagetsi sikokwanira pomwe voliyumu ndiyokwera, zomwe zimapangitsa kusokonekera kwakukulu kwa ma siginolo. Kuphatikiza apo, kupotoza kwa wokamba nkhani mwamphamvu ndi mayankho, ndipo kupotoza kumakwezedwa mozungulira, ndikubweretsa kulira kwa mayankho. Kwenikweni, chifukwa chachikulu cha kubuula ndi kusokonekera. Kuchepetsa kupotoza kumachepetsa mwayi wakubweza mayankho. Komabe, sizinganenedwe kuti sipadzakhala kulira kwa mayankho. Pokhapokha phindu lomwe likupezeka, phindu likakhala lokwanira, zimabweretsa mayankho akulira. Izi zikutanthauza kuti, karaoke power amplifier ayenera kusankha mphamvu yayikulu momwe angathere. Komabe, mphamvu yamphamvu yama amplifier, imamveka kulira kwamphamvu. Kupyolera muzochitikira, njira iliyonse mkati mwa 8 Ω 450W ikhoza kusankhidwa.

Chipinda chochepera ma 18 mita lalikulu ndichopangidwa mwaluso kwambiri pachikhalidwe cha karaoke amplifier.

Chifukwa chachiwiri chogwiritsira ntchito chopangira mphamvu ndi purosesa ya DSP ndikuti njira yokhotakhota yogwiritsira ntchito makina imakhala ndi mayankho ochepa (ochepera 8kHz) komanso kuchepa kwazitsanzo zochepa, zomwe zimapangitsa kusowa kwazinthu m'chilengedwe chomwe chimafuna mphamvu zambiri. Mafupipafupi a DSP a 48K ndi mafupipafupi 20hz-23khz amabweretsa mawu abwinoko komanso kusintha kwapakatikati komanso kotsika kwamphamvu. Ichi ndichifukwa chake sitingathe kuyimba anthu, tikangogwiritsa ntchito zokulitsira mphamvu za DSP, mawu awo amakongoletsa mwadzidzidzi, kukopa kwamaginito, kukopa, ndikumveka bwino.

Chifukwa chachitatu chogwiritsira ntchito chopangira mphamvu ndi purosesa ya DSP ndikuti DSP processor processor imatha kusunga ma data angapo, ndipo itha kubweretsanso zotsatira zowoneka bwino za "reverb", kupatsa ogula zambiri chidziwitso, kuzindikiradi karaoke yodzipangira ya ogula, ndikuchepetsa kwambiri kufunikira kwa ntchito kwa DJ.

Kunena zowona, m'chipinda chayekha pansi pa 18 mita mainchesi, ngati titangowunika mtundu wamalankhulidwe, malingaliro okonzedwa bwino achikhalidwe sakhala otsika poyerekeza ndi a DSP, koma amawoneka olimba komanso ofewa. DSP imakhala ndi kununkhira kwa digito, komwe sikofewa mokwanira. Ngati LPF ya DSP yasinthidwa kukhala 8kHz, kuyerekezera pakati pa ziwirizi ndikowonekera kwambiri. Chosiyanitsa chachikulu ndikulimba kwapafupipafupi, chidwi ndi makulidwe.

Kusankhidwa kwa chophatikizira champhamvu cha karaoke ndi kapangidwe ka kutsogolo ndi kumbuyo makamaka kumadalira zosowa zenizeni za chipinda chofunsira. Zipinda zapakati pa 18 mita mita, ndikulimbikitsidwa kuti musankhe DSP yophatikizira zida zamagetsi zama 200W; kwa zipinda zokhala ndi malo opitilira 18 mita lalikulu mpaka pafupifupi 25 square metres, njira zitatu 200 W DSP karaoke power amplifier zitha kusankhidwa kuti zichulukitse wokamba chapakati ngati mawu oyambira amkati amunthu; chipinda chayekha chokhala ndi ma mita opitilila 25 chikuyenera kuganiziridwa Malinga ndi momwe chipinda chimakhalira, zinthu monga kuthamanga kwa mawu, kufanana pamunda ndikukhazikitsanso gawo lamunda zimaganiziridwa makamaka. Mphamvu yoyenera imasankhidwa ndikuphatikiza mawonekedwe a wokamba nkhani ndi gawo lakumbuyo zokulitsira mphamvu za wokamba nkhani wamkulu. Makina opititsa patsogolo mphamvu yamagetsi yamagetsi angapo atha kugwiritsidwa ntchito pochepetsa mtengo wa wokamba mawu wothandizira wotsika.
