Blackmagic Design ATEM Talkback Converter 4K

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.

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 unmute 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.

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.
