AJA 12G-AMA 12G-SDI 4-Channel Balanced Audio Embedder with Fiber Options

Overview
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.

12G-AMA Workflow
The 12G-AMA in this workflow diagram is receiving 4K video and embedded audio via 12G-SDI. At the same time, the 12G-AMA is disembedding analog audio to the analog audio I/O for mixing.

The output of the mixer is then embedded into the SDI stream being output via the 12G-SDI port of the 12G-AMA. This 12G-SDI output is fed directly to a Ki Pro Ultra 12G to record the original 4K video with the newly embedded, mixed audio.

Supplied Breakout Cable
The included breakout cable supports 1-channel of analog audio per XLR connector for 4-Channels of input and 4-channels of output simultaneously.

USB and Mini-Config Support
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.

Compact and Portable
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.
