AJA 3G-AMA 4-channel analog audio Embedder/Disembedder

AJA 3G-AMA 4-channel analog audio Embedder/Disembedder Overview

The 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.

Video Output Formats

Video Out is a delayed, reclocked version of Video In, at same frame rate, etc. Video Out is undefined when no input.

• Video Latency, time measured between video input and video output connector:

•  3G level A = 3.2 usec
•  3G level B = 6.1 usec
•  HD (1.5 Gb) = 6.3 usec
•  SD (270 Mb) = 17.2 usec
