The Micro Studio Camera 4K includes an iPhone style headphone socket with mic so you get full talkback support. You can also use standard noise canceling headsets, like those from Bose, Sennheiser and more to hear the technical director without distraction from the audience. Because the camera has an SDI connection to the switcher and an SDI connection from the switcher the talkback audio is embedded into channels 15 and 16 of the SDI signal and you get two way communication. If you’re setting up fixed cameras, talkback makes it easy to walk from camera to camera and plug in your headset to communicate with the rest of the crew to get the best angles and framing.
