Professional SeriesUHF Dual ChannelWireless Microphone System

專業系列特高頻雙頻道無線話筒系統

The U-3550 is a dual channel, non-diversity, PLL synthesized wireless microphone system operates in the frequency range of UHF 760 - 950 MHz, It has a built-in sophisticated CPU that can automatically differentiate the receiving signal strength from the 2 antennas of the receiver and adjust the system to the antenna that has stronger signal receiving to avoid signal dropouts and noise interference. The system is also equipped with the latest “NOISE LOCK” dual-squelch circuitry to prevent undesired random noise interference.Upgraded receiver panel with easy-to-read displays and the all-new robust, ergonomic design handheld transmitter offers up to 24 hours battery life with dual AA-3 size alkaline batteries.System offer choices of handheld microphone transmitter or body-pack transmitter with lavalier and headset microphone for different applications.

U-3550 是一台雙頻道非分集式無線話筒系統、採用相位鎖定頻率技術、工作在 UHF 760 - 950 兆赫的頻段範圍、系統內設有一個完善的中央處理器、它能自動地區別來自兩支天線所接收的信號強度及調整系統選擇一個較強的接收信號以避免信號丟失和雜訊的幹擾。系統同時裝備有最新的 “噪音鎖定” 雙重消雜音電路、它可以消除隨機的噪音幹擾。經改良的接收機面板其顯示更能一目了然、全新設計的手持話筒發射器外型優美管身更為紮實堅固、採用兩只市面最普遍的 AA-3 鹼性電池使用時間長達二十四小時。系統設有手持話筒發射器組合、領夾式話筒配腰包式發射器組合及頭戴式話筒配腰包式發射器組合以供選擇。
