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.

Precision Signal Processing

The unit features chips that use 10-bit processing, and are switchable between SD and HD, for a clean signal.
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.

Talkback and Tally

The unit features a built-in speaker and mic inputs, as well as a headphone jack for when you need privacy, or the area is too loud. When connected to the ATEM Camera Converter without needing to worry about walkie talkies. Using the talkback feature, the unit uses audio channels 15 and 16 of the SDI stream for talkback communication.
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.

Optional Optical Fiber Connectors

The ATEM Talkback Converter 4K can be upgraded to use standard single mode optical fiber cable with standard LC connectors to allow you to transmit SD and HD video signals up to 28 miles away. Standard copper wire SDI cables have a limit of several hundred feet before the signal breaks up, converting the SDI signal to optical, and sending it along optical cable greatly increases the distance of your cable runs.
