2CH Wireless Handheld Microphone System

Txheej txheem cej luam

Lub kaw lus wireless siv UHF band wireless kis tau tus mob, ob lub kav hlau txais xov thiab ob txoj hauv kev kom tau txais cov teeb liab, thiab muaj 200 txoj kev xaiv, uas yooj yim rau ntau lub tshuab siv tib lub sijhawm thiab yooj yim zam ntau yam cuam tshuam. Rack-mounted receiver yog ib qho yooj yim rau nruab rau ntawm qhov chaw.

Ob-channel receiver siv ob lub kav hlau txais xov, tus qauv tsim tawm, thiab tsis siv neeg taug qab kev siv thev naus laus zis los xyuas kom meej tias lub kaw lus tswj kev ruaj ntseg zoo ntawm txhua zaus. Nws yog txawm peem rau nrog ob handheld condenser microphones, siv high-zoo dynamic pickups, thiab advanced suab kis tau tus mob technology los xyuas kom meej tias lub rooj sib tham chav tsev muaj meej suab zoo thiab siab fidelity.

Nta

UHF zaus band kis tau tus mob teeb liab, infrared zaus txuam, phau ntawv zaus xaiv yog yooj yim rau ntawm qhov chaw debugging;
Siv ruaj khov PLL digital theem-locked voj synthesis thev naus laus zis thiab ntse digital circuit kom tsis txhob cuam tshuam ntau zaus;
Ob txoj kev tuaj yeem tau txais cov teeb liab mus txog 200 raws, uas yog universal rau handheld duav packs, muaj zog tiv thaiv kev cuam tshuam, thiab muaj peev xwm sib txuas lus thiab siv ib leeg nyob rau hauv cov channel, qhia ib tug humanized high-tech tsim;
Txhua channel tau nruab nrog tus lej ID tshwj xeeb los txhim kho kev cuam tshuam kev cuam tshuam, txhawb nqa txog 12 units siv tib lub sijhawm (xws li 12 receivers thiab 24 transmitters);
Dual-screen LCD zaub screen, qhia zaus channel, RF lub zog, tsis hais, sab hauv polarization ntawm tus kav hlau txais xov, lub sijhawm tiag tiag lub zog thiab hloov cov ntsiab lus ntawm txhua qhov taw qhia hauv cov ntawv qhia zaub mov, lub sij hawm tawm tswv yim ntawm cov txheej txheem ua haujlwm;
Nws muaj qhov hloov suab nrov tshem tawm Circuit Court kom tsis txhob muaj qhov cuam tshuam loj ntawm lub suab thaum tig rau ntawm qhov hloov, ua kom muaj kev nyab xeeb ntawm lub suab nrov tom qab thiab hais lus;
Nws muaj ib qho tseem ceeb tsis siv neeg tshawb nrhiav rau qhov tsis siv neeg zaus cov ntsiab lus thiab ib qho tseem ceeb ntawm kev kaw haujlwm;
Nrog rau kev mob siab rau condenser microphone core thiab nws tus kheej tsim suab ua tshuab, nws zoo txhim kho qhov kev ncua deb thiab kev hais lus meej, nrog cov suab nrov nruab nrab thiab siab zaus, ntau qhov sib txawv, lub suab sib nqus thiab tuab, thiab cov suab nrov ntawm tib neeg, muab kev sib tham zoo dua;
Siv nrug: Qhib ib puag ncig: 80-100 meters Complex ib puag ncig: 50-80 meters
