The AJA 3GDA is a professional 1x6 reclocking distribution amplifier engineered to ensure signal integrity in demanding broadcast and production environments. Its primary function is to take a single incoming 3G-SDI, HD-SDI, or SD-SDI video source and output six identical, independently buffered, and regenerated copies. The "reclocking" aspect is crucial: it actively reconstructs the digital signal's timing on each output, stripping away accumulated jitter and correcting any signal degradation that occurs over long input cable runs. This process guarantees that every downstream device—whether it's a monitor, router, recorder, or encoder—receives a pristine, stable, and broadcast-perfect signal, preventing glitches, dropouts, and synchronization issues that can arise from simply splitting a source passively.

Housed in a compact, rugged half-rack metal enclosure, the 3GDA is built for reliability in both rack-mounted installations and mobile production kits. Its operation is entirely transparent and requires no user configuration; it automatically detects the input signal format (SD, HD, or 3G) and handles the appropriate reclocking. The unit's robust design includes automatic cable equalization on the input to compensate for high-frequency loss, ensuring reliable performance even with suboptimal cabling. As a fundamental building block in any professional video infrastructure, the AJA 3GDA provides a simple, foolproof solution for expanding signal paths with absolute confidence, making it an indispensable tool for maintaining technical quality in facilities ranging from live production trucks to post-production suites and broadcast centers.
