Aja 2x4 or 1x8 3G SDI Reclocking DA

The OG-3GDA-2x4 is an openGear compatible, state of the art 3G-SDI distribution amplifier. The incoming 3G-SDI signals on the input channels are automatically equalized and the outputs are automatically reclocked to four 3G-SDI outputs each or alternatively can function as a 1x 8-channel DA, allowing the same signal to be sent to eight destinations simultaneously. This dual input capability allows double the number of DAs in limited frame space.

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.


The 3G-SDI inputs are automatically equalized and the output(s) is automatically reclocked with best in class input jitter tolerance. SDI rates of 270Mb, 1.5Gb, and 3Gb are supported. Two SDIs inputs and eight SDI outputs are provided.

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.
