Overview of the AJA 3GDA

The AJA 3GDA is a compact and cost-effective 1x6 3G-SDI reclocking distribution amplifier designed to distribute a single SDI signal to multiple outputs without loss of quality. Manufactured by AJA Video Systems, it is built for professional video environments where reliable signal distribution is required.

Signal Distribution Capability

The device takes one SDI input and reproduces it across six separately buffered outputs. Each output delivers an identical signal, ensuring consistent quality across all connected devices such as monitors, switchers, recorders, or encoders.

Format Support and Compatibility

The 3GDA supports 3G-SDI, HD-SDI, and SD-SDI formats. Its format-agnostic design with automatic input detection allows it to integrate seamlessly into mixed-format production environments that still rely on legacy and mid-range SDI standards.

Reclocking and Signal Integrity

The built-in reclocking feature regenerates the SDI signal at standard data rates, reducing jitter and maintaining signal stability. Combined with cable equalization, it helps preserve signal quality over longer cable distances.

HDR and Metadata Pass-Through

The device supports pass-through of SDI ancillary data, including HDR metadata. This ensures that important metadata required for advanced imaging workflows remains intact throughout the distribution chain.

Design and Portability

The miniature form factor allows the 3GDA to be deployed in tight spaces such as behind monitors, inside racks, or mounted on camera rigs. It includes a locking power connector to prevent accidental disconnection and supports universal power input for global use.

Use Cases

The 3GDA is commonly used in broadcast studios, live production setups, and post-production environments where a single SDI signal needs to be distributed reliably to multiple endpoints without signal degradation.
