ʻO ka mea hoʻonui leo kahi mea hana hou i ka hōʻailona leo hoʻokomo i ka mea hoʻopuka e hana i ke kani. ʻO ka nui o ka hōʻailona hōʻailona a me ka pae o ka mana e pono-ʻoiaʻiʻo, maikaʻi a haʻahaʻa haʻahaʻa. ʻO ke kaha leo e pili ana i 20Hz a 20000Hz, no laila pono ka amplifier i kahi pane pinepine pinepine ma kēia pae (ʻoi aku ka liʻiliʻi i ka wā e hoʻokele nei i kahi mea kamaʻilio pinepine ʻia, e like me ka woofer a i ʻole ka tweeter). Kaukaʻi ʻia i ka palapala noi, ʻokoʻa ka pae o ka mana, mai ka pae milliwatt o nā pepeiao pepeiao a i nā watts o ke kīwī TV a PC paha, i nā ʻumi o ka watt home a me ka leo kaʻa "mini" home, i ka home ikaika loa a me ka leo kalepa. ʻO ka ʻōnaehana’s mau haneli watts lawa nui e kū i nā koi kani o ka kinima holoʻokoʻa a i ʻole ka hale hālāwai

ʻO ka mea hoʻonui leo kekahi o nā mea nui o nā huahana multimedia a hoʻohana ākea ʻia i ke kahua o nā uila uila o nā mea kūʻai. Ua lanakila mau nā mea hoʻonui leo leo Linear i ka mākeke amplifier leo kuʻuna ma muli o kā lākou haʻahaʻa haʻahaʻa a me ke ʻano o ke kani maikaʻi. I nā makahiki i hala aku nei, me ka hoʻolaha ʻana o nā hāmeʻa uila hiki ke halihali e like me MP3, PDA, nā kelepona paʻalima, a me nā kamepiula puke, ʻaʻole hiki i ka pono a me ka nui o nā mea hoʻonui mana laina ke hoʻokō i nā koina o ka mākeke, ʻoiai ua hoʻonui nui ʻia nā mea hoʻonui Class D kaulana no ko lākou kūlana kiʻekiʻe a me ka liʻiliʻi. Punahele No laila, he mea nui ka hana kiʻekiʻe Class D power amplifiers waiwai nui a me nā manaʻolana mākeke.

ʻO ka hoʻomohala ʻana o nā mea hoʻonui leo i loaʻa i ʻekolu mau manawa: ka paipu uila (Tube Tube), transistor bipolar, a me ka paipu hopena kahua. ʻO ke kani leo kani o ka paipu, akā nui ia, hoʻohana nui i ka mana, kūpaʻa ʻole, a me ka pane maikaʻi ʻole pinepine ʻole; ʻO ka bipolar transistor leo amplifier ka laulā alapine ākea, ka laulā nui ikaika, ka hilinaʻi kiʻekiʻe, ke ola lōʻihi, a me ka pane pinepine pinepine maikaʻi, akā ʻo kāna hoʻohana mana kūpaʻa a me ke kūʻē ʻana he nui loa ia, a paʻakikī paʻakikī ka hoʻomaikaʻi ʻana. ʻo ka leo hoʻonui leo FET he leo mellow like me ka paipu uila, a ākea kona laulā hōʻeuʻeu, a ʻo ka mea nui, liʻiliʻi kona kūʻē, hiki ke hoʻokō i ka pono kiʻekiʻe.
