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

Professional 12G-SDI Audio Embedding and Disembedding

The AJA 12G-AMA-TR is a high-performance 4-channel analog audio embedder/disembedder Mini-Converter designed for demanding 12G-SDI workflows. Supporting video resolutions up to 4K/UltraHD, this device allows for the seamless integration of analog audio into digital signals or the extraction of audio for external monitoring and processing. This specific model includes an integrated LC Fiber Transceiver, enabling the extension of 12G-SDI signals over long distances with professional-grade reliability.

Audio disembedding is always active, providing four analog outputs. Audio embedding is user-selectable on a channel pair basis, allowing you to either pass the original 12G-SDI input audio or embed new analog audio from the included breakout cable. The 12G-AMA-TR automatically detects and configures the input video standard, ensuring a streamlined setup in any production environment.
