Maikolofoni Opanda Waya a RC-U8021-Ruoca Professional Dual Channel

● Ma frequency 200 UHF angasankhidwe, ndi ntchito yoletsa kusokonezedwa ndi antenna
● Dinani batani la 【IR】 kuti muyike yokha ma frequency olandirira ku chotumizira.
● Kapangidwe ka PLL〔Phase Lock Loop frequency control〕 kamatsimikizira kudalirika kwa ma transmission, "Noise Lock" squelch imatseka bwino RF yosochera.

    Maikolofoni opanda zingwe a UHF aukadaulo - kutumiza mwachangu, kotetezeka komanso kotetezeka

    Dongosolo la maikolofoni opanda zingwe la UHF ili ndi ukadaulo wapamwamba wa PLL (Phase Locked Loop) wopangira ma frequency, womwe umapereka ma frequency point 200 osinthika, womwe umakhudza ma frequency osiyanasiyana a 460-950MHz, umathandizira kulandira njira ziwiri, komanso kukwaniritsa zosowa za zida zingapo kuti zigwiritsidwe ntchito nthawi imodzi. Dongosololi lili ndi luso labwino kwambiri loletsa kusokoneza. Kudzera mu kapangidwe ka antenna grading ndi ntchito ya "noise locking", limateteza bwino kusokoneza kwa RF kwa chilengedwe, limawonetsetsa kuti chizindikirocho chili choyera komanso chokhazikika, ndipo ndi loyenera zochitika zaukadaulo monga zisudzo, misonkhano, ndi kuphunzitsa.

    Lumikizani pafupipafupi mwanzeru

    Ntchito yolumikizirana ya infrared ya [IR] dinani kamodzi kokha, dinani kuti mugwirizanitse ma frequency olandila ku transmitter yokha, kuchotsa kusintha kosasangalatsa kwa ma frequency amanja ndikuwonetsetsa kuti ikugwira ntchito bwino komanso molondola.

    Kutumiza kokhazikika kwambiri

    Kulondola kwa ma frequency okwera kwambiri a ± 0.0005%, kuphatikiza ndi PLL phase-locked loop control, kumathetsa mavuto a ma frequency deviation, ndi ma frequency deviation apamwamba a ± 45KHz, kuonetsetsa kuti palibe kusokoneza ma frequency kapena kuchedwa kwa mawu.

    Kukhulupirika kwakutali

    Mu malo otseguka, mtunda wotumizira uthenga ukhoza kufika mamita 100. Maikolofoni yolumikizira mawu, pamodzi ndi FM modulation, ili ndi mayankho a pafupipafupi a 45Hz ~ 18KHz (± 3dB), ndi kusokonezeka kwathunthu kwa harmonic kwa

    Kapangidwe ka akatswiri

    √ Wolandila: Kapangidwe ka njira ziwiri, mphamvu yowunikira> 105dB, imathandizira bandwidth ya 80MHz, yoyenera kulandira zizindikiro zambiri; magetsi a 100-240V, ogwirizana ndi miyezo yamagetsi yapadziko lonse lapansi.

    √ Kutumiza kumapeto: Mphamvu ya 8mW/12mW RF yosankha, yosinthika kuti ikwaniritse zofunikira zosiyanasiyana zachilengedwe; Yoyendetsedwa ndi mabatire awiri a AA, moyo wa batri ukhoza kukhala mpaka maola 8, ndipo kapangidwe kake ka mphamvu yochepa (120mA) kamawonjezera nthawi yogwiritsira ntchito.

    √ Kutsatira malamulo a chitetezo: Harmonic radiation

    Zochitika zomwe zingagwiritsidwe ntchito

    Kaya ndi masewero a pa siteji, nkhani zamakampani, nkhani za m'kalasi, kapena mawayilesi amoyo akunja, maikolofoni opanda zingwe iyi imatha kupereka chithandizo chokhazikika komanso chodalirika cha mawu aukadaulo. Kapangidwe kake kopepuka ka transmitter, ntchito yosavuta yolumikizirana, komanso moyo wa batri wokhalitsa kumapangitsa kuti kutumiza mawu kukhale kwaulere komanso kugwira ntchito bwino.
    Sankhani mfundo yaikulu, sankhani momveka bwino - pangani phokoso lililonse kukhala lomveka bwino!
