The AJA 3G-AMA is a 4-Channel analog audio Embedder/Disembedder with support for 3G-SDI input and output up to 1080p 60. Audio disembedding is always functional, providing 4 analog outputs. Audio embedding is user selectable, on a channel pair basis, to either pass 3G-SDI input audio or to embed input analog audio from the breakout cable. Analog audio levels are selectable. The 3G-AMA automatically detects and configures to the input video standard.
