Pehea e koho ai i nā amplifier a me nā mea ʻōlelo no nā kī kī bass?

ʻOi aku ka mea nui o ke kīkā bass ma mua o ka amplifier kahi a mākou e hoʻopili ai? ʻAʻole kūpono kēia nīnau, no ka mea, e kani maikaʻi ka bass haʻahaʻa ma ka amplifier maikaʻi, akā ʻaʻole maikaʻi ka mea kani maikaʻi i hui pū ʻia me kahi amp maikaʻi ʻole. Ma kēia alakaʻi, e hana mākou i nā amplifier a me nā leo kani.

Ke kukui a me ka transistor?

"Lamp" - he kuʻuna no nā makahiki he ʻumi, kani maʻamau a puni. ʻO ka mea pōʻino, ʻo ka hoʻohana ʻana i nā amplifiers tube e pili ana i ka pono e hoʻololi i nā paipu i kēlā me kēia manawa, kahi e hoʻonui nui ai i nā kumukūʻai hana o nā " umu ahi", ʻoi aku ka maikaʻi ma mua o ko lākou mau mea hoʻokūkū. Aia kēia hoʻokūkū me nā transistor amplifier. ʻAʻole kūlike ke kani i nā mea hoʻonui tube, ʻoiai i kēia lā ke neʻe wikiwiki nei ka ʻenehana a ke hoʻokokoke nei nā ʻenekinia e hiki i nā ʻano sonic o nā paipu ma o nā transistors. I loko o nā "transistors" ʻaʻole pono ʻoe e hoʻololi i nā paipu, a ma waho aʻe, ʻoi aku ka liʻiliʻi o nā " umu ahi" transistor ma mua o nā paipu. ʻO kahi hopena hoihoi ʻo nā mea hoʻonui hybrid, e hui pū ana i kahi pahu preamplifier me kahi transistor power amplifier. Ua ʻoi aku ka liʻiliʻi ma mua o nā mea hoʻokani pila, akā hoʻopaʻa mau i kekahi o ke kani "tube".

"Musikal" hoalauna

Pono ʻoe e noʻonoʻo me ka pono e hoʻohuli ʻia kēlā me kēia pahu amplifier i kahi pae e kani maikaʻi ai. ʻAʻohe pilikia o nā mea hoʻonui transistor me kēlā, kani maikaʻi lākou ma nā pae haʻahaʻa haʻahaʻa. Inā ʻaʻohe o mākou mau hoalauna e pāʻani ana, no ka laʻana, ka pū a i ʻole ka saxophone, ʻo ka wehe ʻana i ka "kukui" hiki ke lilo i pilikia nui. Eia hou, ua hoʻonuiʻia e kaʻoiaʻiʻo o nā alapine haʻahaʻa iʻoi aku ka maikaʻi o ka hoʻolahaʻana i nā mamao lōʻihi. Noho i ke kūlanakauhale, hiki iā ʻoe ke hana i ka hapalua o ka poloka e hoʻōki i ka makemake iā mākou. Hiki iā mākou ke pāʻani mālie ma ka home ma luna o kahi mea hoʻonui paʻa paʻa a paʻa i nā ʻaha mele. Hiki iā ʻoe ke koho i kahi mea hoʻonui liʻiliʻi liʻiliʻi me kahi ʻōlelo liʻiliʻi, akā naʻe, aia kekahi "akā". Ma nā kīkā bass, ʻoi aku ka maikaʻi o nā leo liʻiliʻi ma mua o nā mea nui no ka mea ʻaʻole lawa lākou e hoʻopuka i nā alapine haʻahaʻa, akā ʻoi aku ka nui ma hope.

Poʻo + kolamu a hui pū paha?

ʻO Combo kahi mea hoʻonui me ka leo leo i loko o ka hale hoʻokahi. ʻO ke poʻo ka ʻāpana e hoʻonui ai i ka hōʻailona mai ka mea kani, ʻo ia ka hana e lawe i ka hōʻailona i hoʻonui ʻia i ka leo kani. ʻO ke poʻo a me ke kolamu he pūʻulu. ʻO nā pono o ka comba ʻoi aku ka maikaʻi o ka neʻe ʻana. ʻO ka mea pōʻino, paʻakikī lākou i ka hoʻololi ʻana i ka leo kani, a ma waho aʻe, ʻo nā transistors a i ʻole nā ​​​​paipu e hōʻike pololei ʻia i ke kaomi kani kiʻekiʻe. He hopena maikaʻi ʻole kēia i kā lākou hana ma kekahi ʻano. I loko o nā hui he nui he ʻoiaʻiʻo hiki ke hoʻopili ʻia kahi ʻōlelo ʻokoʻa, akā inā mākou e hoʻopau i ka mea i kūkulu ʻia i loko, e koi ʻia mākou e lawe i ka ʻōnaehana combo holoʻokoʻa i ka neʻe ʻana o ka amplifier mai kahi a kahi, akā i kēia manawa me kahi ʻōlelo hoʻokaʻawale. I ka hihia o nā stacks, loaʻa iā mākou kahi poʻo kelepona a me nā kolamu kelepona liʻiliʻi, ʻo ka hui pū ʻana he pilikia paʻakikī no ka lawe ʻana. Eia nō naʻe, hiki iā mākou ke koho i ka leo kani poʻo e like me kā mākou makemake. Eia kekahi,ʻaʻole iʻikeʻia nā transistors a iʻole nā ​​paipu i loko o ke "poʻo" i ke kani kani, no ka mea, aia lākou i loko o kahi hale'ē aʻe ma mua o nā leo kani.

Nui a me ka helu o nā kolamu

No nā kīkā bass, he 15 "mea ʻōlelo maʻamau. He mea pono e hoʻolohe inā ua hoʻolako ʻia ka leo kani (e pili pū ana kēia i ka leo kani i kūkulu ʻia i ka combach) me kahi tweeter. I ka hapanui o nā hihia he 1 "a aia ma ke kolamu like me ka mea haʻi'ōlelo nui. ʻAʻole pono ia, akā hoʻomaikaʻi iā ia, loaʻa ka puʻu bass i kahi puʻu i ʻōlelo ʻia, koʻikoʻi i ka haki ʻana i ka hui ʻana i ka wā e pāʻani ai me kou mau manamana lima a i ʻole ka hulu, a me ka ʻenehana clang.

ʻOi aku ka nui o ka leo kani, ʻoi aku ka maikaʻi o ka hiki ke mālama i nā alapine haʻahaʻa. ʻO ia ke kumu e koho pinepine ai ka poʻe bassist i nā leo leo me 15 "a i ʻole 2 x 15" a i ʻole 4 x 15 "mea kani. I kekahi manawa hoʻohana pū ʻia nā hui pū me kahi ʻōlelo 10 ”. Hāʻawi ka 15 "speaker i ka bass nui, a ʻo ka 10" ke kuleana no ka haki ʻana i ka hui luna (kahi hana like e pāʻani ʻia e nā tweeters i kūkulu ʻia i loko o nā mea haʻiʻōlelo me kahi "speaker" 15). I kekahi manawa hoʻoholo nā mea pāʻani bass e hele i ka 2 x 10 "a i ʻole 4 x 10" e hoʻoikaika i ka holomua ma ka hui luna. ʻOi aku ka paʻakikī o ka bass e puka mai ana mai laila, a makemake paha i nā manawa he nui.

Aia kekahi mau lula e hoʻomanaʻo i ke koho ʻana i nā kolamu. E hāʻawi wau iā ʻoe i nā ala palekana loa. Aia kekahi, ʻoiaʻiʻo, nā mea ʻē aʻe, akā e kālele kākou i ka poʻe i pilikia ʻole. Inā maopopo ʻole ʻoe i kekahi mea, e nīnau i kahi loea. ʻAʻohe ʻakaʻaka me ka uila.

I ka hiki ʻana i ka mana, hiki iā mākou ke koho i kahi leo kani e like me ka mana o ka amplifier. Hiki iā mākou ke koho i kahi leo kani me ka mana haʻahaʻa ma mua o ka amplifier, akā pono ʻoe e hoʻomanaʻo ʻaʻole e hoʻokaʻawale nui i ka amplifier, no ka mea hiki iā ʻoe ke hōʻino i nā mea ʻōlelo. Eia kekahi, hiki iā ʻoe ke koho i kahi leo kani me ka mana kiʻekiʻe ma mua o ka amplifier. I kēia hihia, ʻaʻole pono ʻoe e hoʻonui me ka wehe ʻana i ka amplifier, i ʻole e hōʻino ʻia, no ka mea e hoʻāʻo paha mākou e hoʻohana i ka mana piha o nā mea haʻiʻōlelo i nā koina āpau. Inā hoʻohana mākou i ka haʻahaʻa, pono nā mea a pau. Hoʻokahi palapala hou. No ka laʻana, ʻo kahi amplifier me ka mana o 100 W, me ka ʻōlelo colloquially, "hāʻawi" 200 W i kahi ʻōlelo 100 W. kēlā me kēia o lākou.

I ka hiki ʻana i ka impedance, ʻokoʻa iki. Pono mua ʻoe e nānā inā loaʻa iā ʻoe kahi pilina parallel a serial. I ka nui o na hihia, hana like ia. No laila, inā loaʻa iā mākou kahi pilina like me ka amplifier, e laʻa me ka impedance o 8 ohms, hoʻohui mākou i hoʻokahi leo 8-ohm. Inā hoʻoholo ʻoe e hoʻohana i 2 leo kani, pono ʻoe e hoʻohana i 2 16 – ohm leo kani no ka mea hoʻonui like. Eia nō naʻe, inā loaʻa iā mākou kahi pilina moʻo, hoʻopili pū mākou i kahi mea ʻōlelo 8-ohm i kahi amplifier me kahi impedance o 8 ohms, akā eia kahi e pau ai nā mea like. I ka hihia o kahi pilina moʻo, hiki ke hoʻohana ʻia ʻelua kolamu 2-ohm no ka amplifier like. Hiki ke hana ʻia kekahi mau ʻokoʻa, akā hiki i ka hewa ke loaʻa nā hopena koʻikoʻi. Inā ʻaʻole ʻoe maopopo he 4%, e hahai i kēia mau lula palekana.

He aha ka mea e nānā ai?

ʻO ka maʻamau ʻo Bass amplifier he 1 wale nō kaila maʻemaʻe, a i ʻole 2 awāwa i maʻemaʻe a ʻino. Inā koho mākou i kahi amplifier me ka ʻole o kahi kaila distortion, e nalowale mākou i ka hiki ke loaʻa i kahi kani distorted wale nō e hoʻomaikaʻi i ka amplifier. ʻAʻole kēia he pilikia nui. I kēlā hihia, kūʻai wale i ka distortion waho. Pono ʻoe e nānā i ka hoʻoponopono ʻana. Hāʻawi kekahi mau mea hoʻonui i ka EQ multi-band no nā hui pākahi, akā hāʻawi ka hapa nui i ka "bass - mid - treble" EQ. ʻO ka manawa pinepine, ua hoʻolako ʻia nā bass amplifier me kahi limiter (kahi compressor hoʻonohonoho kūikawā), ka mea e pale ai i ka amplifier mai ka distortion makemake ʻole. Eia hou, hiki iā ʻoe ke loaʻa i kahi compressor maʻamau e hoʻohālikelike i nā pae leo ma waena o ka pāʻani mālie a me ka hakakā. I kekahi manawa, kūkulu ʻia ka modulation a me nā hopena spatial, akā he mau mea hoʻohui wale nō kēia a ʻaʻole pili i ke kani kumu. Inā makemake ʻoe e hoʻohana i ka modulation waho a me nā hopena hoʻopuni, e nānā inā loaʻa i ka amplifier kahi loop FX i kūkulu ʻia. ʻOi aku ka maikaʻi o ka modulation a me nā hopena spatial me ka amp ma o ka loop ma mua o waena o ka bass a me ka amp. Hoʻopili mau ʻia ka wah – wah, distortion a me ka compressor ma waena o ka amplifier a me ka mea kani. He mea nui e nānā inā hāʻawi ka amplifier i ka mea hoʻohui hui. Hoʻopaʻa pinepine ʻia ka bass i ka linearly, a me ka ʻole o ka puka ʻana he mea hiki ʻole. Inā makemake kekahi i kahi puka headphone, pono nō hoʻi e hōʻoia i loko o ka amplifier i hāʻawi ʻia.

Loaʻa

He mea pono ke hoʻohui i ka bass i kahi mea waiwai, no ka mea he nui ke kuleana o ka amplifier i ka hana ʻana i ke kani. ʻAʻole pono e hoʻohaʻahaʻa ʻia ka pilikia o ka "stove" inā makemake ʻoe e kani maikaʻi.
