AJA 12G-SDI, 4-Channel Balanced Audio Embedder / Disembedder with Fiber Options (12G-AMA)

Professional 12G-SDI Audio Integration

The AJA 12G-AMA is a high-performance 4-channel analog audio embedder/disembedder Mini-Converter. It supports 12G-SDI input and output for resolutions up to 4K/UltraHD at 60p. This device is essential for workflows requiring precise audio mapping and signal conversion in professional broadcast and post-production environments.

Versatile Audio Management

Audio disembedding is always active, providing four analog outputs. Embedding is user-selectable on a channel-pair basis, allowing you to pass 12G-SDI input audio or embed new analog audio from the included breakout cable. The 12G-AMA automatically detects and configures the input video standard for seamless operation.
