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.
Camera operators can be selected individually if desired, and communication can be controlled by a push button, or locked open. Mute and un-mute buttons on the front of the unit allow you to control who hears what.
The unit passes SDI Tally signal information back to the cameras along with any SDI Program signal from available switchers.
The unit features eight independent simultaneous SDI to optical and optical to SDI converters (with the optional fiber terminals), when used in conjunction with the ATEM Camera Converter the unit can also be used as four independent SDI or Fiber to HDMI converters.
