AJA OG-3G-AMA Specifications

OG-3G-AMA

An openGear 8-Channel analog audio embedder/disembedder, OG-3G-AMA supports 3G-SDI input
and output up to 1080p 60, and automatically detects and configures to the input video standard.
It uses 3-pin terminal block connectors that can be set to perform audio input or output
functionality. Analog audio levels and audio embedding/disembedding are selectable, with
embedding/disembedding on a channel pair basis to pass 3G-SDI input audio or embed input
analog audio from 3-pin terminal block connectors.

Designed for use in high density openGear 2RU frames including AJA’s OG-X-FR frame, new
DashBoard Software support on Windows®, macOS® and Linux® offers remote control and
monitoring of the openGear architecture and provides convenient and industry-standard
configuration, monitoring and control options over a PC or local network.
