With 12G-SDI, Blackmagic Design‘s ATEM Talkback Converter 4K accepts high-resolution video from up to eight studio cameras or ATEM Camera Converters and allows the control room to interact with the camera operators. The 12G-SDI connections can support video with resolutions up to 4096 x 2160 at 60 fps and rout those individual signals to a switcher via SDI outputs, to a program monitor via its own SDI output, and back to the camera operator while carrying talkback audio over a single cable. Talkback audio can be captured via a microphone plugged into the XLR jack on the front, or a headset mic plugged into the appropriate jack, also on the front panel.
This unit can be upgraded to accept fiber optic connections, which carry, bi-directional 4K video, audio, and talkback for up to 28 miles without signal degradation. And because of its 1 RU size, it can easily fit into industry standard rack-mount equipment and furniture.
