Qala ukulenga kunoma yiluphi uhlobo lokuqopha, lokuprakthiza noma lwensiza yokusebenza bukhoma futhi uzokuzwa amagama athi 'ileveli yemakrofoni' kanye 'neleveli yomugqa' aphonswa kakhulu.
Ileveli yemakrofoni isho okokufaka lapho imibhobho axhunyiwe, kanti ileveli yomugqa isho okokufaka kwanoma iyiphi enye idivayisi yomsindo noma insimbi.
Umehluko omkhulu phakathi kwemakrofoni nokungena ngaphakathi kufaka okulandelayo:
- Umsebenzi: Ama-mics ajwayele ukusetshenziselwa ama-microphone ngenkathi i-line in isetshenziselwa izinsimbi
- Okufakwayo: I-mics isebenzisa okokufaka kwe-XLR ngenkathi ulayini usebenzisa a Jack okokufaka
- Amazinga: Amazinga ayahluka ngokuya ngokuthi yiziphi izinsimbi ezihlala kuzo
- voltage: Amandla ezinhlobo zesiginali ahluka kakhulu
Lo mbhalo uzobheka ngokujulile umehluko phakathi kombhobho nolayini ukuze ube nolwazi oluhle oluyisisekelo lobuchwepheshe bomsindo.
Yini iMic Level?
Izinga leMic libhekisa kumandla ombane akhiqizwa lapho imakrofoni ithatha umsindo.
Ngokuvamile, lokhu kuyizinkulungwane ezimbalwa nje ze-volt. Noma kunjalo, ingahluka ngokuya ngezinga lomsindo nebanga ukusuka kumakrofoni.
Uma kuqhathaniswa namanye amadivayisi womsindo, ileveli yemakrofoni ngokuvamile ibuthakathaka kakhulu futhi imvamisa idinga i-preamplifier noma i-mic ukulinganisa ulayini ukuyisiza ifike ezingeni lomugqa kuzinsimbi.
Lokhu kutholakala njengamadivayisi wesiteshi esisodwa neziteshi eziningi.
Isixubi singasetshenziselwa lo msebenzi futhi empeleni siyithuluzi elithandwayo lomsebenzi ngoba lingahlanganisa amasiginali amaningi kokukhipha okukodwa.
Izinga le-mic livame ukukalwa ngezilinganiso ze-decibel dBu ne-dBV. Imvamisa iwela phakathi kuka -60 no -40 dBu.
Liyini Line Line?
Izinga lomugqa licishe liphindwe ka-1,000 XNUMX liqine njengeleveli yemakrofoni. Ngakho-ke, laba bobabili abavami ukusebenzisa umphumela ofanayo.
Isiginali ihamba isuka kusitampu iye esikhulisweni esikhiqiza umsindo ngezipikha zayo.
Kunamazinga womugqa amabili ajwayelekile afaka okulandelayo:
- -10 dBV yemishini yabathengi efana neDVD neMP3 players
- +4 dBu okokusebenza kochwepheshe njengokuxuba amatafula nempahla yokucubungula amasiginali
Uzothola nezimpawu zomsindo kumazinga wezinsimbi nezipikha. Izinsimbi ezinjengesigingci namabhasi zidinga ukuqiniswa kuqala ukuze zikhuphule zifike ezingeni lomugqa.
Amazinga esikhulumi se-post amplification yilokho okuphuma ku-amp kuya kuzipikha.
Lezi zinevolthi ephakeme kakhulu kuneleveli yomugqa futhi idinga izintambo zesipikha ukudlulisa isignali ngokuphepha.
Ukubaluleka Kwamazinga Okumatanisa
Kubalulekile ukufanisa idivayisi efanele nokufakwayo okulungile.
Uma ungakwenzi lokho, ngeke uthole umphumela oyifunayo, futhi ungazibeka engcupheni yokuziphoxa esimweni sobungcweti.
Nazi ezinye izibonelo zalokho okungahamba kabi.
- Uma uxhuma imakrofoni ngokufaka kwezinga lomugqa, ngeke uthole noma yimuphi umsindo. Lokhu kungenxa yokuthi isiginali yemakrofoni ibuthakathaka kakhulu ukushayela okokufaka okunamandla.
- Uma uxhuma umthombo wezinga lomugqa kokufakwayo kweleveli yemakrofoni, kuzokwehlula amandla okufakwayo okuholela kumsindo ohlanekezelwe. (Qaphela: Kwamanye ama-mixers asezingeni eliphakeme, okokufaka kweleveli kanye nokufakwayo kwezinga le-mic kungashintshana).
Amacebiso Awusizo
Nawa amanye amathiphu angakusiza uma usesitudiyo.
- Okokufaka kwileveli ye-mic ngokuvamile kunezixhumi ze-XLR zesifazane. Okokufaka kwezinga lomugqa kungowesilisa futhi kungahle kube ama-RCA jacks, i-3.5mm jack jack, noma i-¼ ”jack jack.
- Ngoba isixhumi esisodwa singena kwesinye, lokho akusho ukuthi amazinga ayafana. Ezimweni eziningi, okokufaka kuzomakwa ngokucacile. Lokhu kumakwa kufanele kube ukuya kwakho.
- I-attenuator noma ibhokisi le-DI (Direct Injection) lingasetshenziswa ukunciphisa i-voltage kudivayisi. Lokhu kungaba wusizo uma udinga ukuxhuma ileveli yomugqa ezintweni ezinjengezirekhoda zedijithali namakhompyutha anokufaka kwe-mic kuphela. Lezi zingathengwa ezitolo zomculo futhi zize ngezinguqulo zekhebula ezinama-resistors akhelwe ngaphakathi.
Manje njengoba wazi izisekelo ezithile zomsindo, uwulungele kangcono umsebenzi wakho wokuqala wobuchwepheshe.
Yiziphi ezinye zezifundo ezibalulekile onomuzwa wokuthi ama-techs kufanele azi?
Ukufunda kwakho okulandelayo: Ama-Consoles ahamba phambili weSitudiyo sokurekhoda abukeziwe.
NginguJoost Nusselder, umsunguli we-Neaera kanye nomkhangisi wokuqukethwe, ubaba, futhi ngiyathanda ukuzama izinto ezintsha ngesiginci enhliziyweni yesifiso sami, futhi kanye nethimba lami, bengilokhu ngidala izindatshana zebhulogi ezijulile kusukela ngo-2020. ukusiza abafundi abathembekile ngokurekhoda namathiphu esiginci.
