Ke koho ʻana i kahi amplifier no kāu ʻōnaehana leo

I ka nānā mua ʻana, ʻike paha ʻaʻole maʻalahi ke kaʻina o ke koho ʻana i kahi amplifier i loko o kahi kaʻa no nā mea ʻōlelo a i ʻole subwoofer. Akā ʻo ka loaʻa ʻana o kahi aʻo pōkole "Pehea e koho ai i kahi amplifier" ʻaʻole ia e pilikia. ʻO ke kumu o ka amplifier no ka ʻōnaehana leo, ʻo ia ka lawe ʻana i kahi hōʻailona haʻahaʻa haʻahaʻa a hoʻololi iā ia i kahi hōʻailona kiʻekiʻe e hoʻokele i ka mea haʻiʻōlelo.

He ʻokoʻa paha lākou i ka helu o nā kaha amplification, ka mana a me ke kumukūʻai. ʻO nā mea hoʻonui ʻelua a me ʻehā-channel i ka makemake nui loa ma waena o nā kaʻa. A i kēia manawa e pane mākou i ka nīnau pehea e koho ai i kahi amplifier i kahi kaʻa i nā kikoʻī hou aku.

Nā papa hoʻonui kaʻa

ʻO ka mea mua, makemake wau e kamaʻilio e pili ana i nā papa amplifier, i kēia manawa he nui ka nui o lākou, akā e noʻonoʻo mākou i ʻelua mau mea nui i maʻamau i nā ʻōnaehana leo kaʻa. Inā makemake ʻoe i kēia kumuhana i nā kikoʻī hou aku, ma ka hope o ka ʻatikala aia kahi wikiō e kamaʻilio e pili ana i nā papa āpau o nā amplifiers kaʻa i loaʻa i kēia manawa.

• Mea hoʻonui papa AB. Loaʻa i kēia mau mea hoʻonui ke kani maikaʻi loa, me ka pilina kūpono ua hilinaʻi lākou a paʻa. Inā loaʻa ka mana kiʻekiʻe o kahi amplifier papa AB, a laila loaʻa iā ia ka nui o ka nui, ʻo kēia mau amplifiers he haʻahaʻa haʻahaʻa ma kahi o 50-60%, ʻo ia hoʻi inā hānai ʻia nā 100 watts iā lākou. ka ikehu, a laila e hiki i ka manawa o 50-60 watts i nā mea ʻōlelo. Hoʻololi wale ʻia ke koena o ka ikehu i ka wela. ʻAʻole hiki ke hoʻokomo i nā amplifier papa AB ma kahi pani pani, inā ʻaʻole, i ka wā wela, hiki ke hele i ka pale.
• Mea hoʻonui papa D (hoʻonui kikohoʻe). ʻO ke kumu, loaʻa ka papa D i nā monoblocks (hoʻokahi-channel amplifier), akā aia pū kekahi ʻehā a me ʻelua-kanal no ka hoʻopili ʻana i nā acoustics. He nui nā pono o kēia amplifier. Ke hoʻohālikelike ʻia me ka papa AB, me ka mana like, loaʻa iā ia nā ʻāpana koʻikoʻi. Hiki i ka pono o kēia mau mea hoʻonui ke hiki i 90%, ʻaʻole ia e wela. Hiki i ka papa D ke hana paʻa ma lalo o ka haʻahaʻa ohmic haʻahaʻa. Maikaʻi nā mea a pau, akā ʻoi aku ka maikaʻi o ke kani o kēia mau mea hoʻonui i ka papa AB.

Hoʻopau mākou i kēia ʻāpana me kahi hopena. Inā ʻoe e ʻimi nei i ka maikaʻi leo (SQ), a laila ʻoi aku ka pololei o ka hoʻohana ʻana i nā amplifier papa AB. Inā makemake ʻoe e kūkulu i kahi ʻōnaehana leo nui, a laila ʻoi aku ka maikaʻi o ke koho ʻana i nā amplifier Class D.

Ka helu o nā kaha hoʻonui.

ʻO ka mea nui aʻe ka helu o nā kaha amplifier, pili ia i ka mea hiki iā ʻoe ke hoʻopili iā ia. He mea maʻalahi nā mea a pau, akā e nānā pono kākou:

         

• ʻO nā mea hoʻonui hoʻokahi-channel, ua kapa ʻia lākou he monoblocks, ua hoʻolālā ʻia lākou e hoʻopili i nā subwoofers, ʻoi aku ka nui o ka papa D a me ka hiki ke hana i ka haʻahaʻa haʻahaʻa. Hoʻonohonoho ʻia nā hoʻonohonoho (filter) no ka subwoofer, ʻo ia hoʻi, inā ʻoe e hoʻopili i kahi ʻōlelo maʻalahi i ka monoblock, e hana hou ia i ka bass o kēia manawa.

 

• Nā mea hoʻonui ʻelua-kanal, e like me kāu e manaʻo ai, hiki iā ʻoe ke hoʻohui i kekahi mau mea ʻōlelo iā ia. Akā ʻo ka hapa nui o nā amplifiers ʻelua-kanal hiki ke hana ma ke ʻano bridged. ʻO kēia ka wā e hoʻopili ʻia ai kahi subwoofer i ʻelua mau kahawai. Loaʻa i kēia mau amplifiers nā hoʻonohonoho āpau (filter), ʻo ia hoʻi he hoʻololi HPF lākou, hana hou kēia ʻano i nā alapine kiʻekiʻe o kēia manawa, a i ka wā e hoʻololi ai i ka kānana LPF, e hoʻopuka ka amplifier i nā alapine haʻahaʻa i ka hopena o kēia manawa (pono kēia hoʻonohonoho no kahi subwoofer) .
• Inā maopopo iā ʻoe ke ʻano o ka amplifier ʻelua-channel, a laila maʻalahi nā mea a pau me ʻehā-channel, ʻo ia nā mea hoʻonui ʻelua ʻelua, ʻo ia hoʻi, hiki iā ʻoe ke hoʻohui i ʻehā mau mea ʻōlelo iā ia, a i ʻole 2 mau mea ʻōlelo a me kahi subwoofer, i nā manawa liʻiliʻi ʻelua subwoofers. pili, akā ʻaʻole mākou e paipai e hana i kēia. E wela loa ka amplifier a i ka wā e hiki mai ana hiki ʻole ke hoʻohana.
  
  ʻEkolu a me ʻelima amplifiers kakaikahi loa. He mea maʻalahi nā mea a pau maʻaneʻi, hiki iāʻoe ke hoʻohui iʻelua mau mea'ōlelo a me kahi subwoofer i kahi mea hoʻonuiʻekolu-channel, 4 mau mea'ōlelo a me kahi subwoofer i kahi amplifierʻelima. Loaʻa iā lākou nā kānana a pau no ka hoʻopaʻa ʻana i nā ʻāpana i pili iā lākou, akā ma ke ʻano he kānāwai, liʻiliʻi ka mana o kēia mau amplifier.

I ka pau ʻana, makemake wau e ʻōlelo i kēia. Inā he mea hou ʻoe i ka leo kaʻa a makemake ʻoe e kiʻi i ka leo kiʻekiʻe, kaulike, aʻo mākou iā ʻoe e koho i kahi amplifier ʻehā. Me ia, hiki iā ʻoe ke hoʻohui i nā mea ʻōlelo mua a me kahi subwoofer passive. Hāʻawi kēia iā ʻoe i kahi mua ikaika maikaʻi, kākoʻo ʻia e kahi loulou subwoofer.

Mana hoʻonui.

ʻO ka mana kekahi o nā palena nui loa. ʻO ka mea mua, e noʻonoʻo kākou i ka ʻokoʻa ma waena o ka mana helu a me ka mana kiʻekiʻe. ʻO ka mea hope, ma ke ʻano he lula, ua hōʻike ʻia ma ka hihia amplifier, ʻaʻole ia e like me ka ʻoiaʻiʻo a hoʻohana ʻia ma ke ʻano he promo pass. I ke kūʻai ʻana, e hoʻolohe i ka mana helu (RMS). Hiki iā ʻoe ke ʻike i kēia ʻike ma nā ʻōlelo kuhikuhi, inā ʻike ʻia ke kumu hoʻohālike, hiki iā ʻoe ke ʻike i nā ʻano ma ka Pūnaewele.

I kēia manawa he mau huaʻōlelo e pili ana i ke koho ʻana i ka mana o ka amplifier a me nā mea ʻōlelo. Makemake ʻoe e aʻo hou e pili ana i ke koho ʻana i ka leo? E heluhelu i ka ʻatikala "pehea e koho ai i nā acoustics kaʻa". Loaʻa i nā mea kamaʻilio kaʻa ka mana helu, ma nā kuhikuhi i kapa ʻia ʻo RMS. ʻO ia, inā loaʻa i ka acoustics ka mana helu o 70 watts. A laila e like ka mana nominal o ka amplifier, mai 55 a 85 watts. ʻO ka laʻana ʻelua, he aha ke ʻano o ka amplifier e pono ai no kahi subwoofer? Inā loaʻa iā mākou kahi subwoofer me ka mana helu (RMS) o 300 watts. Pono ka mana o ka amplifier he 250-350 watts.

Paukū hopena. ʻOi aku ka maikaʻi o ka mana nui, akā ʻaʻole pono ʻoe e alualu iā ia, no ka mea, aia nā amplifiers me ka liʻiliʻi o ka mana, a ʻoi aku ka maikaʻi o ka pāʻani a ʻoi aku ka leo ma mua o nā mea kūʻai ʻole akā me kekahi hana exorbitant.

inoa mea hana.

 

I ke kūʻai ʻana i kahi amplifier, he mea nui e hoʻolohe i ka mea hana hana. Inā kūʻai ʻoe i kahi huahana hana lima, ʻaʻole hiki iā ʻoe ke hilinaʻi i ka maikaʻi leo maikaʻi. ʻOi aku ka maikaʻi o ka huli ʻana i nā hōʻailona pupule i kū i ka mākeke no ka manawa lōʻihi a ua loaʻa mua ka mahalo a me ka waiwai i ko lākou inoa. No ka laʻana, nā hui e like me Hertz, Alpine, DLS, Focal. Mai nā mea kālā hou aku, hiki iā ʻoe ke hoʻohuli i kou manaʻo i nā hōʻailona e like me; Alphard, Blaupunkt, JBL, Ural, Swat, etc.

Ua hoʻoholo anei ʻoe i ke koho o ka amplifier? ʻO ka ʻatikala aʻe e pono ai ʻoe "pehea e hoʻopili ai i kahi amplifier kaʻa."

Pehea e koho ai i ka amplifier ma ke kaʻa (wikiō)

Nā mea hoʻonui no SQ. Pehea e koho ai i ka amplifier ma ke kaa

ʻOiaʻiʻo, ʻaʻole kēia nā hōʻailona āpau e pono ai ʻoe e hoʻolohe i ke koho ʻana i kahi amplifier, akā ʻo lākou nā mea nui. Ma hope o nā ʻōlelo aʻoaʻo i hōʻike ʻia ma ka ʻatikala, hiki iā ʻoe ke koho i kahi amplifier kūpono no kāu ʻōnaehana leo. Lana ko mākou manaʻo ua pane mākou i kāu nīnau e pili ana i ke koho ʻana i kahi amplifier no nā mea haʻiʻōlelo a i ʻole kahi subwoofer, akā inā loaʻa iā ʻoe nā manaʻo maopopo ʻole a makemake paha, e hauʻoli mākou e pane iā ia ma nā ʻōlelo ma lalo!
