MS-8, a simple switcher equipped with the same built-in scaler as an A-PRO-4. All you have to do is to connect all the video sources to the MS-8 unit and then you can switch between them just by pressing respective buttons as needed. Even if connected video sources are of heterogeneous formats, the built-in scaler optimally manages them to present all the visual contents. The unit is equipped with two-channel stereo inputs for external audio input. The USB terminals can output streams for live video streaming.
