UHF 調(diào)頻真分集系列：采用PLL真分集接收電路，確保接收機(jī)唯一接收本系統(tǒng)發(fā)射的信號(hào)，紅外對(duì)頻，性能穩(wěn)定，聲音清晰，保真度高，動(dòng)態(tài)范圍大，工作距離達(dá)到200米，適合戶外專業(yè)演出使用。

UHF selectable frequency series: PLL true diversity circuit which ensures a high sensitivity and stable reception to the transmitted signal. Infrared frequency, wide frequency response and strong rejection to noise disturbance thanks to audio compression/expansion technology which results in zero noise output and increased dynamic range. Perfect for outdoor professional performance.
