The AJA 12G-AMA-TR is a 4-channel analogue audio embedder/disembedder mini-converter, supporting 12G-SDI input and output up to 4K/UltraHD. It is fitted with a single-link LC fibre transceiver. Audio disembedding runs continuously, always delivering four analogue outputs, while embedding is user-selectable on a channel-pair basis — either passing the incoming SDI audio through or embedding analogue audio supplied on the breakout cable. Fibre-equipped models across the 12G-AMA range are available with LC or ST connectors, in transmitter, receiver or transceiver configurations. Configuration is via USB and AJA's Mini-Config software, or DIP switches.
