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.

Video Path Delay
Video Out is a delayed, reclocked version of Video In, at the same frame rate, etc. Video Out is undefined when no input.
- Video Latency, time measured between video input and video output connector:
- 12G = 3.2 µsec
- 6G = 3.2 µsec
- 3G level B (Dual Stream HD mode) = 6.3 µsec
- 3G level A = 3.2 µsec
- HD (1.5 Gb) = 6.3 µsec
