MDA 5V

主要特性

Extron MDA 5V 是一款紧凑的 1 路输入、5 路输出复合视频分配放大器。它通过一个 BNC 插座接收复合视频，并通过五个 BNC 插座将放大的信号输出至 45 m (150') 远的距离。

MDA 5V 可安装在机架或桌下，并随附一个外置电源。它小巧的尺寸能轻松地安装在新的和已有的视音频系统，包括董事会议室、培训中心、家庭剧院、指挥控制中心和舞台租赁等环境。

特性

• 通过 BNC 插座接受并分配复合视频信号
• 输入环出
• 400 MHz (-3 dB) 视频带宽，满载
• 可安装在机架、桌下和投影机上，每个机架能安装 4 个
• 随附外置  Extron Everlast™  电源，产品编号 #70-1175-01 — 该全球通用型电源具有经验证的高可靠性和低功耗，能够降低运行成本
• Extron Everlast 电源可享受 7 年部件及人工保修
