The 12G-AM is an 8-channel AES audio embedder/disembedder Mini-Converter with support for 12G-SDI input and output up to 4K/UltraHD.

AES Audio disembedding is always functional, providing four AES outputs. Audio embedding is user selectable, on a channel pair basis, to either pass 12G-SDI input audio or to embed input AES audio from the breakout cable.

The 12G-AM automatically detects and configures the input video standard.

Fiber models also available. Fiber models offer single link fiber I/O including LC and ST options.
