Phantom Power Compatibility: XLR vs. TRS
Phantom simba izwi rakajairika muindasitiri yekuteerera. Inzira yekusimbisa maikorofoni inoda simba rekunze kuti rishande. Phantom simba ndeye DC voltage inopfuudzwa nepamaikorofoni tambo kuti isimbise maikorofoni. Nepo XLR ma-connectors ari iwo akajairika nzira yekupfuura phantom simba, haisiriyo nzira chete. Muchikamu chino, tichakurukura kana phantom simba rinoshanda chete neXLR kana kwete.
XLR vs. TRS Connectors
XLR zvibatanidza zvakagadzirirwa kutakura zvakadzikama masaini masaini uye anowanzo shandiswa maikorofoni. Vane mapini matatu: positive, negative, uye pasi. Simba rePhantom rinotakurwa pamapini akanaka uye asina kunaka, uye pini yepasi inoshandiswa senhovo. TRS connectors, kune rumwe rutivi, ine maviri conductor uye pasi. Iwo anowanzo shandiswa mahedhifoni, magitare, uye zvimwe zvekuteerera.
Phantom Simba uye TRS Connectors
Nepo XLR maatanidzi ari iwo akajairika nzira yekupfuudza phantom simba, TRS zvinongedzo zvinogona kushandiswa zvakare. Nekudaro, haazi ese maTRS makubatanidza akagadzirirwa kutakura phantom simba. TRS zvibatanidza zvakagadzirirwa kutakura phantom simba zvine chaiyo pini kumisikidzwa. Iyi inotevera mimwe mienzaniso yeTRS yekubatanidza iyo inogona kutakura phantom simba:
- Rode VXLR+ series
- Kutasva SC4
- Kutasva SC3
- Kutasva SC2
Izvo zvakakosha kuti utarise iyo pini yekumisikidza usati washandisa TRS yekubatanidza kupfuudza phantom simba. Kushandisa chinongedzo chisina kunaka chinogona kukanganisa maikorofoni kana midziyo.
Ko Phantom Simba Ingozi kune Giya Rako?
Phantom simba inzira inowanzoshandiswa yekusimbisa maikorofoni, kunyanya condenser maikorofoni, nekutumira voltage kuburikidza netambo imwechete inotakura chiratidzo chekuteerera. Kunyange ichiwanzo chikamu chakachengeteka uye chinodiwa chebasa redhiyo rehunyanzvi, pane dzimwe njodzi uye kufunga kwekurangarira.
Kudzivirira Magiya Ako
Pasinei nenjodzi idzi, simba rephantom rinowanzo chengeteka chero richishandiswa nemazvo. Hedzino dzimwe nzira dzekuchengetedza giya rako:
- Tarisa giya rako: Usati washandisa phantom simba, ita shuwa kuti giya rako rese rakagadzirirwa kuzvibata. Tarisa nemugadziri kana kambani kana usina chokwadi.
- Shandisa tambo dzakadzikama: Tambo dzakadzikama dzakagadzirirwa kudzivirira kubva kune ruzha rusingadiwe uye kukanganisa, uye inowanzodiwa pakushandisa simba rephantom.
- Dzima simba rephantom: Kana usiri kushandisa maikorofoni inoda simba rephantom, ita shuwa yekudzima kuti udzivise chero kukuvara kunogona kuitika.
- Shandisa musanganisi ane phantom simba rekudzora: Musanganisi ane ega ega ega ega ega ega ega anogona kubatsira kudzivirira chero netsaona kukuvara kugiya rako.
- Iva neruzivo: Kana iwe uri mutsva pakushandisa phantom simba, zvinokurudzirwa zvakanyanya kuti ushande neane ruzivo nyanzvi yekuteerera kuti uve nechokwadi chekuti uri kuishandisa nemazvo uye zvakachengeteka.
The Bottom Line
Phantom simba chikamu chakajairika uye chinodiwa chebasa redhiyo rehunyanzvi, asi rinotakura dzimwe njodzi. Nekunzwisisa njodzi idzi uye kutora matanho anodiwa, unogona kushandisa zvakachengeteka simba rephantom kuti uwane ruzha rwaunoda pasina kukuvadza giya rako.
