AJA 12G-SDI Input and Output up to 4K / UltraHD with ST Fiber Transmitter (12G-AMA-T-ST)

Overview

The AJA 12G-AMA-T-ST is a high-performance 4-channel analog audio embedder/disembedder Mini-Converter designed for demanding 12G-SDI workflows. Supporting resolutions up to 4K/UltraHD, this model includes an integrated ST Fiber transmitter, enabling the extension of high-bandwidth signals over long distances with professional reliability.

Audio disembedding is always functional, providing four analog outputs, while audio embedding is user-selectable on a channel pair basis. This allows operators to either pass 12G-SDI input audio or embed analog audio from the included breakout cable. The device features automatic detection of input video standards for seamless integration into any production environment.
