AJA's 12G-AMA-R is a 4-channel analog audio embedder/disembedder MiniConverter. It supports 12G-SDI input and output up to 4K/UltraHD single link, with fiber I/O including LC and ST options.
Analog audio can be embedded and disembedded simultaneously. Audio disembedding is always functional, providing four analog outputs. Audio embedding is user selectable, on a channel pair basis, to either pass SDI embedded audio or to embed input analog audio from the breakout cable. Analog audio operating levels are selectable, via USB connection and Mini-Config software.
The ability to pass incoming ancillary data makes it possible to embed up to 16 channels of audio by cascading four units. Horizontal ancillary data (HANC) packets in compliance with SMPTE 291M can also be passed through or removed at the input.
The 12G-AMA automatically detects and configures to the input video standard. 12G-SDI formats up to and including 4096x2160p 60 YCbCr 4:2:2 are supported (see "Appendix A Specifications" on page 22 for a complete listing). SDI video passes through the device with minimal delay. Pass through embedded SDI audio supports up to 16 channels.
