The OG-3GDA-1x9 is a state of the art, openGear compatible, 3G-SDI distribution amplifier. The incoming 3G-SDI signal is reclocked and distributed to each of the nine 3G-SDI outputs, allowing the same signal to be sent to multiple destinations simultaneously.

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


The 3G-SDI input is automatically equalized and the outputs are automatically reclocked with best in class input jitter tolerance. SDI rates of 270Mb, 1.5Gb, and 3Gb are supported. One SDI input and nine SDI outputs are provided. A 10x BNC rear openGear connector module is included.

openGear Compatibility

The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rackframe products.

Flexible I/O

The modular rear panel allows custom I/O connections per card (included with individual cards).


The optional redundant power supply provides a secondary power source in the event of a primary power failure.

Ethernet Access

A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.
