AJA 12G-SDI Input and Output up to 4K / UltraHD with LC Fiber Receiver (12G-AMA-R)

Professional 12G-SDI Audio Embedding and Disembedding

The AJA 12G-AMA-R is a high-performance 4-channel analog audio embedder/disembedder Mini-Converter designed for demanding 4K/UltraHD workflows. This model features an integrated LC Fiber Receiver, enabling the reception of 12G-SDI signals over long distances with minimal signal degradation. Whether in a studio or a live environment, the 12G-AMA-R provides the reliability and high-bandwidth capabilities required for modern 12G-SDI infrastructure.

Versatile Audio Integration

Audio disembedding is always functional, providing four analog outputs for immediate routing or monitoring. Audio embedding is user-selectable on a channel pair basis, allowing you to either pass 12G-SDI input audio or embed new analog audio from the included breakout cable. With selectable analog audio levels, this converter adapts seamlessly to various professional and consumer audio environments.

Advanced Video Support and Auto-Detection

The 12G-AMA-R automatically detects and configures the input video standard, supporting resolutions from SD and HD up to 4K and UltraHD at frame rates up to 60p. Its compact form factor ensures it fits into tight spaces, while the rugged construction is built for the rigors of field use.
