AJA 12G-AMA-R 12G-SDI embedder/disembedder audio analogico con XLR a 4 canali

The AJA 12G-AMA-R is a professional 12G-SDI analog audio embedder and disembedder, designed for broadcast and production environments. It supports simultaneous embedding and disembedding of 4-channel analog audio over a single 12G-SDI link, with reclocked loop-through and processed SDI outputs. The unit features four balanced XLR inputs and outputs, switchable between line and mic levels, and is powered via 5-20V DC with an included universal power supply.

Advantages

Compact and robust, the 12G-AMA-R simplifies audio integration in 4K/UltraHD/2K/HD/SD workflows. Its reclocked loop-through output ensures signal integrity, while the processed output allows for flexible audio routing. The USB control interface via AJA Mini-Config software provides easy setup and monitoring.
