AJA 12G-AMA 12G-SDI Audio Embedder/Disembedder with Analog Audio

The AJA 12G-AMA is a professional Mini-Converter that embeds or disembeds up to four channels of analog audio over a single 12G-SDI connection. Supporting SDI standards from SD to 12G, it handles video formats up to 4K/UltraHD at 60p. The unit features one 12G-SDI input with a loop-through output and a processed output, plus four balanced XLR analog audio inputs and outputs. Control is via USB 2.0 using AJA Mini-Config software or DIP switches. Powered by +5V DC (AJA DWP-U-R1 universal power supply included), it consumes only 4.5W typical. Ideal for broadcast, production, and post-production environments requiring reliable audio embedding or disembedding.

Advantages

Compact and robust Mini-Converter design ensures easy integration into any setup. Supports the latest 12G-SDI standard for 4K/UltraHD workflows while maintaining backward compatibility with 6G, 3G, HD, and SD-SDI. Four balanced analog audio channels provide high-quality 24-bit/48 kHz audio. Loop-through output allows daisy-chaining without signal degradation. Low power consumption and included universal power supply make it field-ready.
