AJA 12G-SDI 8-Channel AES Embedder / Disembedder with ST Fiber Tx SFP (12G-AM-T-ST)

Professional 12G-SDI Audio Integration

The AJA 12G-AM-T-ST is a high-performance 8-channel AES audio embedder/disembedder Mini-Converter designed for the most demanding 12G-SDI workflows. Supporting video resolutions up to 4K/UltraHD, this model features an integrated ST Fiber Transmitter SFP, enabling reliable signal extension over long distances via fiber optic cabling.

Audio management is exceptionally flexible: disembedding is always active across four AES outputs, while 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 input AES audio from the included breakout cable. The device automatically detects and configures the input video standard, ensuring a seamless setup in complex broadcast or live event environments.
