Description
The AJA 12G-AMA Analog Audio Embedder/Disembedder (4 Channel) is a 4-channel analog audio embedder/disembedder Mini-Converter with support for 12G-SDI input and output up to 4K/UltraHD. Fibre models offer single link fibre 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.
AJA Mini-Converters are small enough to fit behind a monitor, in the back of a rack or directly on a camera rig. A locking power connector can't accidentally pull loose, and an optional P-TAP power cable allows for battery power in remote locations.
AJA’s free Mini-Config software can be used with any USB-enabled AJA Mini-Converter and provides an easy-to-use graphical interface with detailed information about the current input and output formats. Control all the parameters of any supported AJA Mini-Converter as well as loading firmware updates from AJA that add new features and functionality.
