AJA 12G-AMA - Embedder/Disembedder 4K 12G-SDI and O.F.

AJA-12G-AMA

The 12G-AMA is a 4-channel analog audio embedder/disembedder Mini-Converter with support for 12G-SDI input and output up to 4K/UltraHD. Fiber models offer single link fiber I/O including LC and  ST options. 

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

Analog audio levels are selectable. The 12G-AMA automatically detects and configures the input video standard.
