The switcher features four multiview outputs with up to 16 routable windows that can display inputs, keyed video, graphics, and stills from the media pool, as well as the program output. Each input connects to a built-in FairLight audio mixer, supporting up to 298 channels of audio. There are also two MADI inputs and four MADI outputs for audio mixing and routing.

Reference and Control

The switcher has a reference input, and each input features a frame synchronizer, frame rate converter, and format converter, allowing you to mix and match cameras that do not have genlock capabilities.
