Extron MVX 系列矩阵切换器设计用于传输最常见的带立体声音频的高分辨率计算机视频信号。MVX 系列支持从 4x4 至 16x16 不等的输入/输出尺寸，提供宽带切换功能，通过 15 针 HD 插座实现各类计算机视频的便捷连接。在 MVX 系列产品中，4x4 至 8x8 尺寸的型号接受通过 3.5 mm 微型立体声插孔传输的非平衡立体声音频，而 12x8 至 16x16 尺寸的型号接受通过螺丝锁定器传输的平衡或非平衡立体声音频。所有型号都支持通过螺丝锁定器输出平衡或非平衡立体声音频。使用预端接电缆组件（如 Extron 带音频的 VGA 电缆）可以省却压接操作，使安装过程更为快速便捷。
