　　MLS 406、MLS 406MA 和MLS 406SA MediaLink® 切换器是易于使用的六路输入多格式有源切换器.

　　作为用于单投影机教室和会议室的简约型解决方案，三种型号都提供复合视频、S- 视频、计算机视频和音频切换功能。MLS - MediaLink 切换器设计用来与 MLC - MediaLink 控制器一起工作，有助于低成本的集成。也可以作为独立的切换器使用。

特性

　·集成式的单声道音频放大器提供 20 watts rms 给 4 或 8 ohm 扬声器或提供 16 watts rms 给 70/100 volt 的分散式音频系统；同时通过隔离的螺丝端子输出经过放大的单声道音频信号。

　·280 MHz (-3 dB) RGB 视频带宽

　·可通过MLC - MediaLink 控制器、前面板按钮或 RS-232 来控制

　·本地监视器输出

　·通过RS-232 控制音频输入增益和衰减

　·固定及可变的线路电平音频输出

　·辅助/ 混合音频输入

　·音量可通过RS-232 或 MLC - MediaLink 控制器进行调节

　·响度控制
