Extron MLS 100A MediaLink® 切换器是一台结构紧凑、4 路输入1 路输出的有源音频切换器，通过螺丝锁定器输入及输出.
输入1至4 提供非平衡音频，还有一个附加输入作有源辅助线路电平单声道输入，它可与其他四个可选输入中的其一混合。通过RS-232 或MLC 206 MediaLink 控制器，可方便控制MLS 100A 的输入切换及音量控制。此切换器还可以通过面板输入按键或RS-232 控制。
特性
·4 个螺丝锁定器作可切换音频输入，每个输入都具有独立的增益和衰减
·附加输入接受单声道线路电平信号，可与4 个输入中的其一混合
·当与MediaLink 系统集成或作为第三方RS-232 控制系统的一部分时，音量控制可调
·通过面板按键或RS-232 控制
·可机架安装，MLS 100A 装在1U 高、1/4 机架宽的金属机箱内
