Nā ʻokoʻa ma waena o XLR Audio a me XLR DMX

I kekahi lā, hoʻomaka kēlā me kēia o mākou e ʻimi i nā kaula kūpono i hoʻopau ʻia me kahi plug XLR kaulana. Ke nānā nei mākou i nā huahana o nā hōʻailona like ʻole, ʻike mākou i ʻelua mau noi nui: Audio a me DMX. Ke nānā aku nei - ua like nā kaula, ʻaʻole ʻokoʻa kekahi i kekahi. ʻO ka mānoanoa like, nā plugs like, ke kumu kūʻai ʻokoʻa wale nō, no laila pono ke uku? ʻOiaʻiʻo, nui ka poʻe a hiki i kēia lā ke nīnau iā lākou iho i kēia nīnau. E like me ka mea i ʻike ʻia - ma waho o ka helehelena māhoe, nui nā ʻokoʻa.

hoʻohana

ʻO ka mea mua, pono e hoʻomaka me kāna mau noi kumu. Hoʻohana mākou i nā kaula leo XLR no nā pilina ma ke ala leo, nā pilina nui o ka microphone / microphones me ka mixer, nā mea hana ʻē aʻe e hana ana i ka hōʻailona, ​​​​ka hoʻouna ʻana i ka hōʻailona mai ka mixer i ka mana amplifiers, etc.

Hoʻohana nui ʻia nā kaula XLR DMX e kāohi i nā mea uila naʻauao. Mai kā mākou mea hoʻomālamalama kukui, ma o nā kaula dmx, hoʻouna mākou i nā mea ʻē aʻe i ka ʻike e pili ana i ka ikaika o ka māmā, ka hoʻololi ʻana o ke kala, e hōʻike ana i kahi ʻano i hāʻawi ʻia, a me nā mea ʻē aʻe. hana.

Building

Loaʻa nā ʻano ʻelua i ka insulation mānoanoa, ʻelua uea a me ka pale. Hoʻohana ʻia ka insulation, e like me ka mea i ʻike ʻia, e pale i ka conductor mai nā kumu o waho. Hoʻopili ʻia nā kaula a ʻōwili ʻia, mālama ʻia i loko o nā pahu paʻa, hehi pinepine a kūlou. ʻO ke kumu ke kū'ē maikaʻi i nā mea i'ōleloʻia ma luna a me ka maʻalahi. Hana ʻia ka pale pale e pale i ka hōʻailona mai ka hoʻopili electromagnetic mai ke kaiapuni. ʻO ka pinepine ma ke ʻano o ka alumini alumini, keleawe a i ʻole alumini braid.

ʻO nāʻokoʻa nui

Hoʻolālā ʻia nā uwea microphone no nā hōʻailona leo, kahi o ke alapine i hoʻololi ʻia ma ka laulā 20-20000Hz. ʻO ke alapine hana o nā ʻōnaehana DMX ʻo 250000Hz, ʻoi aku ka nui, ʻoi aku ka "kiʻekiʻe".

ʻO kekahi mea ʻo ka impedance hawewe o kahi kaula i hāʻawi ʻia. Ma nā uwea DMX he 110 Ω, ma nā uwea leo ma lalo o 100 Ω. ʻO nā ʻokoʻa o nā impedances e alakaʻi i ka hoʻohālikelike ʻana i ka nalu maikaʻi ʻole a, no laila, nalowale ka ʻike i hoʻouna ʻia ma waena o nā mea hoʻokipa.

Hiki ke hoʻohana like ʻia?

Ma muli o nā ʻokoʻa kumukūʻai, ʻaʻohe mea e hoʻohana i nā kaula DMX me kahi microphone, akā ʻo ke ʻano ʻē aʻe, hiki iā ʻoe ke ʻike pinepine i kēia ʻano o ka mālama kālā, ʻo ia hoʻi ka hoʻohana ʻana i nā kelepona leo ma ka ʻōnaehana DMX.

Hōʻike ka hoʻomaʻamaʻa hiki ke hoʻohana like ʻole me ka nānā ʻole i kā lākou hoʻohana ʻana a ʻaʻohe pilikia no kēia kumu, akā naʻe, hiki ke ʻae ʻia kēlā ʻano kumu ma lalo o kekahi mau kūlana, e like me ka laʻana o nā ʻōnaehana kukui maʻalahi i hoʻolako ʻia me nā mea ʻaʻole ākea a me ka pili pōkole. mamao (a hiki i kekahi mau mika).

Loaʻa

ʻO ke kumu nui o nā pilikia a me nā hemahema o nā ʻōnaehana i kūkākūkā ʻia ma luna nei he mau kaula haʻahaʻa haʻahaʻa a me nā pilina ʻino, ʻo ia ke kumu he mea nui e hoʻohana i nā kaula wale no kahi noi kikoʻī a hoʻolako ʻia me nā mea hoʻohui maikaʻi.

Inā loaʻa iā mākou kahi ʻōnaehana kukui nui e pili ana i nā mea he nui, he mau kakini a i ʻole mau haneli mau mika o nā uea, pono ia e hoʻohui i nā kaula DMX i hoʻolaʻa ʻia. E mālama pono kēia i ka ʻōnaehana a hoʻopakele iā mākou mai nā manawa hopohopo ʻole.
