MIPRO AD-708 是一款 UHF 寬頻四頻道自動增益控制天線分配器,專為多頻道無線麥克風與專業無線音訊系統所設計,可將兩組天線訊號穩定分配至最多四台無線接收機,大幅簡化天線架構,同時維持高度穩定的 RF 接收品質。對於舞台演出、會議系統、廣播製作、宗教場所與大型活動現場而言,AD-708 是建構多接收機系統時不可或缺的核心設備。
AD-708 支援 UHF 470 ~ 850 MHz 寬頻頻段,涵蓋目前主流無線麥克風與數位無線系統使用的頻率範圍,可靈活對應不同頻段規劃需求。其內建的自動增益控制(AGC)電路,能即時偵測同軸電纜因長距離傳輸所造成的訊號衰減,並自動進行補償,確保各接收機端獲得一致且穩定的 RF 訊號強度,避免因天線距離不同而導致接收靈敏度不均。
在射頻設計上,AD-708 採用超寬頻微帶增益補償架構,具備極低的內調失真(Intermodulation Distortion),可有效抑制多頻道同時運作時所產生的混頻干擾,特別適合高密度頻道配置的專業應用環境。這項特性在大型舞台或多支無線麥克風同時使用的情境下尤為關鍵,有助於維持乾淨、穩定且可預期的 RF 表現。
AD-708 亦支援系統串接擴充,透過串接輸出可再連接其他天線分配器,建構更大規模的多接收機系統,而不需額外增加天線數量,進一步降低天線佈線的複雜度。輸入端同時提供天線偏壓輸出,可直接為主動式天線或天線強波器供電,減少額外電源配置需求。
面板上的 LED 狀態指示燈,可即時顯示天線連線與系統運作狀態,讓工程人員能快速掌握現場 RF 架構是否正常運作。當搭配 MIPRO MPB-30 天線強波器使用時,AD-708 可協同補償長距離傳輸造成的訊號損耗,進一步提升整體系統的接收穩定度與可靠性。
