- Mana whakaputa: ko te waeine he W, nā te mea he rerekē ngā tikanga ine a ngā kaihanga, nō reira kua rerekē ngā ingoa o ētahi huarahi. Pērā i te mana whakaputa whakatauranga, te mana whakaputa mōrahi, te mana whakaputa puoro, te mana whakaputa puoro tihi.

- Mana puoro: e pā ana ki te kore e neke ake te whakapōturitanga putanga i te uara kua tohua o te āhua, ka tere te whakaputanga o te mana whakakaha i runga i te tohu puoro.

- Mana Tino Kaha: e pā ana ki te mana puoro mōrahi ka taea e te whakakahaoro te whakaputa ina whakatikatikaina te rōrahi o te whakakahaoro ki te mōrahi me te kore he whakapōturitanga.

- Mana Putanga Whakatauria: Ko te mana putanga toharite ina 10% te whakapōturitanga o te harmonic. E mōhiotia ana hoki ko te mana whai hua mōrahi. I te nuinga o te wā, he nui ake te mana tihi i te mana puoro, he nui ake te mana puoro i te mana whakatauria, ā, ko te mana tihi he 5-8 ngā wā o te mana whakatauria.

- Urupare Auau: E tohu ana i te whānuitanga auau o te whakakaha mana, me te nui o te kore taurite i roto i te whānuitanga auau. Ko te pihi urupare auau ka whakaatuhia i roto i ngā tiipere (db). Ko te urupare auau o te whakakaha HI-FI kāinga he 20Hz–20KHZ tāpiri atu, tango atu rānei i te 1db. Ko te whānui ake o te whānuitanga, ko te pai ake. Ko ētahi o ngā urupare auau whakakaha mana pai rawa atu kua mahia i waenganui i te 0 – 100KHZ.

- Te nui o te whakapōturi: Ko te whakakaha mana tino pai ko te whakakaha tohu tāuru, me te whakahoki pono tonu. Heoi, nā ngā take maha, he maha ngā wā ka puta he rerekē ngā nekehanga o te whakapōturi i te tohu i whakakahangia e te whakakaha mana ki te tohu tāuru, arā, he whakapōturi. Ki te whakaatuhia hei ōrau, ko te iti ake te pai. Ko te katoa o te whakapōturi o te whakakaha HI-FI kei waenga i te 0.03% -0.05%. Kei roto i ngā whakapōturi o te whakakaha mana ko te whakapōturi harmonic, te whakapōturi intermodulation, te whakapōturi cross, te whakapōturi cutting, te whakapōturi transient, te whakapōturi intermodulation transient me ētahi atu.

- Ōwehenga tohu-ki-haruru: e pā ana ki te taumata o te ōwehenga tohu-ki-haruru o te putanga whakakaha mana, me te nui ake o te db, ko te pai ake. Ko te ōwehenga tohu-ki-haruru whakakaha mana HI-FI whānui o te whare neke atu i te 60db.

- Ātete putanga: Ko te ātete ā-roto ōrite o te pūorooro, e kiia nei ko te ātete putanga

Whakakaha Kaha o ngā hongere PX Raupapa 2

Te tiaki i te whakakaha hiko：

1. Me whakanoho e te kaiwhakamahi te whakakaha oro ki tētahi wāhi maroke, hauhautanga hoki, kia kore ai e mahi i roto i tētahi taiao makuku, pāmahana teitei, me te waikura.

2. Me whakanoho e te kaiwhakamahi te whakakaha oro ki roto i tētahi tēpu, kāpata rānei e haumaru ana, e kore e ngāwari ki te taka, kia kore ai e pā, e hinga rānei ki te whenua, kia kore ai e kino te mīhini, kia kore ai hoki e puta he aituā nui atu nā te tangata, pērā i te ahi, te ru hiko me ērā atu.

3. Me karo ngā kaiwhakamahi i ngā taiao wawaotanga hikohiko kino, pērā i te koroheketanga o te papa o te rama fluorescent me ētahi atu wawaotanga hikohiko irahiko ka whakararuraru i te hōtaka CPU o te mīhini, ka kore e taea e te mīhini te mahi tika.

4. Ina honoa te waea PCB, kia mahara kia kaua e tawhiti rawa te waewae hiko me te wai, ka taea te tāpiri i te 1000 / 470U ki tōna waewae.
