AV mixers, which play a core role in audio-visual production is the A-PRO-4 that supports information sharing in real time, such as live video streaming via the internet. Particularly, the A-PRO-4 has professional-grade SDI, consumer-grade HDMI and analog video inputs, and one of the inputs has a built-in scaler that allows users to connect devices without worrying about resolutions or frame rates. For an external sound source, the unit has one stereo input available for adding a commentary or background music.
