Sony's MCX-500 8-Input 4-Video Channel Global Production Streaming/Recording Switcher is much more than just a portable 8-input switcher. It is a global system that supports both 60 and 50 Hz production formats, so you can work with it virtually anywhere in the world. Four 3G-SDI inputs, two HDMI, and two composite (CVBS) inputs each feature a discrete frame synchronizer, allowing you to mix input sources. The unit internally processes the input footage at 1080i.
