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

Professional 12G-SDI Audio Embedding and Disembedding

The AJA 12G-AMA-T is a high-performance 4-channel analog audio embedder/disembedder Mini-Converter designed for demanding 4K/UltraHD workflows. This specific model includes an integrated single-link LC Fiber Transmitter, enabling professionals to extend high-resolution 12G-SDI signals over long distances with ease.

The device offers exceptional flexibility: audio disembedding is always active, providing four analog outputs, while audio embedding is user-selectable on a channel-pair basis. This allows you to either pass the original 12G-SDI input audio or replace it with analog audio sourced from the included breakout cable.

Advanced Video and Audio Control

Equipped with automatic video standard detection, the 12G-AMA-T simplifies setup by instantly configuring itself to match the input signal. Users can fine-tune analog audio levels via the AJA Mini-Config software or utilize the external DIP switches for quick adjustments in the field. The compact, rugged design ensures it fits into any production environment, from broadcast trucks to studio racks.
