AD-808 - UHF 寬頻四頻道發射天線整合器｜專業無線監聽與舞台應用首選
AD-808 是一款專為專業舞台演出與無線監聽系統所設計的 UHF 寬頻四頻道發射天線整合器。其核心功能在於將最多四台 UHF 發射器的 RF 訊號，整合並集中輸出至單一天線進行發射，大幅簡化多天線並存時所帶來的架設複雜度與潛在干擾問題。
在大型演唱會、巡演舞台、電視攝影棚或專業監聽系統中，當多組 In-Ear Monitoring（IEM）或無線發射器同時運作時，天線數量與擺放位置往往成為影響穩定度的關鍵。AD-808 透過內建 高線性寬頻放大電路，在整合多路訊號的同時，有效抑制互調失真（Intermodulation Distortion），降低訊號合併後可能產生的品質劣化，確保音訊傳輸的穩定性與清晰度。
此外，AD-808 的 0 dB 增益設計可在不額外放大 RF 功率的情況下，維持訊號原始動態與系統平衡，避免過度放大造成干擾外溢，特別適合需要嚴格控管 RF 環境的專業現場。面板配置的 LED 訊號指示燈，能即時顯示各輸入通道的功率狀態，讓工程人員在現場即可快速掌握系統運作情形。
整體而言，AD-808 是一款以「穩定、簡化、專業」為設計導向的 UHF 發射天線整合方案，能有效提升無線監聽與發射系統的可靠度，並讓舞台與機櫃配置更加整潔有序。
