The AJA D5DA is a compact, high-quality SD-SDI (Serial Digital Interface) distribution amplifier designed for professional broadcast and video production environments. This device takes one standard definition SDI video input and provides five identical, reclocked outputs. Its primary function is to distribute a single video source to multiple destinations, such as monitors, recorders, switchers, and other processing gear, without any signal loss or degradation. The automatic input equalization ensures that signals arriving over long cable runs are restored before being reclocked and distributed.

The unit is built to AJA's high standards for reliability and performance in mission-critical applications. Its small size makes it easy to integrate into existing rack systems or portable production kits. The D5DA supports a range of standard definition formats including 525/60 (NTSC) and 625/50 (PAL) at a 270 Mb bit rate. The self-configuring input detection and robust construction make it a dependable workhorse for video engineers needing simple, effective signal distribution.
