Kev tshaj lij UHF wireless microphone system - kev sib kis siab, ruaj khov tiv thaiv kev cuam tshuam
Lub tshuab microphone UHF wireless no siv cov thev naus laus zis PLL (Phase Locked Loop) uas siv thev naus laus zis siab heev, muab 200 qhov chaw hloov kho zaus, npog ntau qhov zaus ntawm 460-950MHz, txhawb nqa kev txais ob txoj kev sib txuas, thiab ua tau raws li qhov xav tau ntawm ntau lub cuab yeej rau kev siv tib lub sijhawm. Lub kaw lus muaj peev xwm tiv thaiv kev cuam tshuam zoo heev. Los ntawm kev tsim qauv antenna thiab "suab nrov xauv", nws tiv thaiv kev cuam tshuam RF ib puag ncig, ua kom lub teeb liab huv thiab ruaj khov, thiab tsim nyog rau cov xwm txheej kev tshaj lij xws li kev ua yeeb yam, kev sib tham, thiab kev qhia ntawv.
Cov txiaj ntsig tseem ceeb
Kev sib dhos zaus ntse
Ib qho nias [IR] infrared synchronization function, nias kom synchronize zaus ntawm tus txais rau lub transmitter, tshem tawm qhov kev hloov kho zaus tes tsis zoo thiab ua kom muaj kev ua haujlwm zoo thiab raug.
Kev sib kis tau ruaj khov siab
± 0.0005% qhov tseeb ntawm qhov zaus siab heev, ua ke nrog PLL theem-xauv lub voj voog tswj, tshem tawm cov teeb meem zaus sib txawv, nrog rau qhov siab tshaj plaws zaus sib txawv ntawm ± 45KHz, kom ntseeg tau tias tsis muaj kev cuam tshuam zaus lossis qeeb hauv suab.
Kev sib txuas lus ntev ntev siab fidelity
Hauv qhov chaw qhib, qhov kev sib kis tau mus txog 100 meters. Lub microphone dynamic directional unit, ua ke nrog FM modulation, muaj qhov teb zaus ntawm 45Hz ~ 18KHz (± 3dB), nrog rau qhov kev cuam tshuam tag nrho ntawm
Kev teeb tsa parameter kev tshaj lij
√ Tus Txais: Tsim ob txoj kev sib txuas, rhiab heev> 105dB, txhawb nqa 80MHz bandwidth, haum rau ntau qhov chaw teeb liab txais tos; 100-240V dav voltage muab, sib xws nrog cov qauv fais fab thoob ntiaj teb.
√ Xaus xa: xaiv tau 8mW/12mW RF fais fab, yoog tau raws li qhov xav tau ntawm ib puag ncig sib txawv; Siv 2 lub roj teeb AA, lub roj teeb lub neej tuaj yeem kav ntev txog 8 teev, thiab tus qauv tsim hluav taws xob tsawg (120mA) txuas ntxiv lub sijhawm siv.
√ Kev ua raws li kev nyab xeeb: Kev tawg harmonic
