Ubwino
Makina a maikolofoni opanda zingwe a Professional True Diversity UHF - kutumiza kwamphamvu kwambiri
Ndi ma frequency 100 omwe amatha kukonzedwa, ma frequency ambiri a 460-950 MHz, kulandira njira ziwiri, komanso kuthandizira zida zingapo kuti zigwiritsidwe ntchito nthawi imodzi, makina a maikolofoni opanda zingwe a UHF awa amagwiritsa ntchito ukadaulo wapamwamba wa PLL (Phase Locked Loop) popanga ma frequency. Mphamvu za makinawa zoletsa kusokoneza ndi zabwino kwambiri. Zimalepheretsa bwino kusokoneza ma frequency a wailesi, zimatsimikizira kukhazikika kwa chizindikiro ndi kuyera, ndipo ndizoyenera makonda aukadaulo monga misonkhano, zisudzo, ndi malangizo chifukwa cha kapangidwe kake ka antenna ndi mawonekedwe a "noise locking".
Ubwino
Lumikizani pafupipafupi mwanzeru
Pogwiritsa ntchito njira yolumikizirana ya infrared ya [IR] kamodzi kokha, ma frequency a transmitter ndi receiver amalumikizidwa okha, kuchotsa kufunikira kwa kusintha kwa ma frequency pamanja kovutirapo ndikutsimikizira kuti ntchitoyo ikuyenda bwino komanso molondola.
Kutumiza kokhazikika kwambiri
Kuwongolera kwa PLL phase-locked loop ndi kulondola kwa ma frequency apamwamba kwambiri a ± 0.0005% kumachotsa mavuto a ma frequency deviation, ndi ma frequency deviation apamwamba a ± 45KHz, kutsimikizira kuti palibe kusokonezeka kwa ma frequency kapena kuchedwa kwa mawu.
Mtunda wautali ndi kukhulupirika kwakukulu
Mtunda wotumizira mauthenga mpaka mamita 100 ukhoza kupezeka pamalo otseguka. Mayankho a pafupipafupi a maikolofoni oyendetsera mawu okhala ndi FM modulation ndi 45 Hz mpaka 18 KHz (± 3dB), ndipo kusokonezeka konse kwa harmonic kuli kochepera 0.4%. Mawu a munthu ndi zida zoimbira nyimbo zonse zili ndi mawu omveka bwino komanso osavuta kumva.
