MIPRO AD-708 UHF 寬頻四頻道自動增益控制天線分配器|兩組天線分給四台接收機、自動補償纜線損耗,多支無線麥克風系統的天線整合核心

MIPRO AD-708 是一台 UHF 寬頻四頻道天線分配器,可把兩支天線(A/B)收到的訊號分配給最多四台 UHF 無線麥克風接收機,讓多台機架型接收機共用一組天線,不必每台各插兩支天線;支援 UHF 470~850 MHz 寬頻範圍,並可透過串接輸出再接一台分配器擴充系統。全機架寬(19 吋)1U 金屬機箱,適合舞台演出、會議系統、宗教場所與大型活動中多支無線麥克風同時運作的環境。

AD-708 內建自動增益控制電路,能偵測並補償同軸電纜造成的訊號衰減,讓每台接收機都拿到一致穩定的 RF 訊號;採用超寬頻微帶增益補償設計,內調失真極低,能有效排除多頻道同時運作時的混頻干擾。輸入接頭提供 DC 8.3 V/230 mA 天線偏壓,可直接為 MIPRO 主動式天線或 MPB-30 強波器供電,搭配強波器時可自動補償長距離傳輸損耗。

產品特色
