Nta:
- Siv UHF520-690MHz zaus band kom tsis txhob cuam tshuam zaus;
- Yooj yim thiab yooj yim rau kev khiav lag luam;
- Tsis siv neeg infrared zaus, kom lub transmitter thiab receiver tau synchronize xa thiab txais;
- 200 raws nrog PLL zaus synthesis stabilization system;
- 4 pawg ntawm kev ywj pheej RF thiab IF systems nrog 4 tus kav hlau txais xov zoo siab;
- Qhov tseeb high zaus lim yog siv los lim tawm tawm-ntawm-band cuam tshuam cov teeb liab mus rau qhov siab tshaj plaws.
- High zaus Circuit Court tsim nrog hloov dua siab tshiab zaus, nrog tsis tshua muaj siab rhiab heev;
- Ntau lub squelch tswj Circuit Court tsis lees txais kev cuam tshuam sab nraud;
- Microphone siv dual boost tsim, roj teeb lub zog poob tsis cuam tshuam rau lub zog xa mus
- Tshwj xeeb tsim lub suab compression thiab expansion Circuit Court zoo heev txhim kho lub teeb liab-rau-suab nrov piv.
- Cov qauv tsim tshwj xeeb hauv Circuit Court, loj dynamic, dav zaus teb, tsis tshua muaj suab nrov;
- Kev ua haujlwm engineering, kev tshaj tawm hauv tsev kawm ntawv, kev tshaj tawm pej xeem, chaw ua si, thiab lwm qhov chaw ua haujlwm nyob deb;
- Ua haujlwm nrug: ntau tshaj 100m sab hauv tsev thiab 260m sab nraum zoov;
