1RU 4K/UltraHD/HD/SD Frame Sync/Converter, 1-Channel 4K/Ultra HD, or 4 Independent Channel HD/SD Frame Syncs




The 4-Channel 2K/HD/SD or 1-Channel 4K/UltraHD Frame Synchronizer from AJA offers incredible versatility and connectivity in a sleek 1RU frame for 4K/UltraHD and 2K/HD/SD conversion needs. Offering a wide range of connection options for both video and audio, this frame synchronizer can do the work of four separate devices in 2K/HD/SD or combine all processors and channels together for maximum flexibility for 4K/UltraHD productivity.

In single channel mode, the synchronizer will upscale your HD or SD materials to 4K/UltraHD and back, with a huge array of audio channels over Fiber, 3G-SDI, AES, and MADI for an incredible 272 x 208 matrix of audio possibilities.

In 4-Channel mode, it provides multi-channel conversion with up to 4-channels of simultaneous processing for 2K/HD and SD signals. The processing allows ROI (Region of Interest) scaling, color correction, proc amp controls, motion adaptive de-interlacing, and much more.

  • Single channel mode provides a full suite of 4K/UltraHD processing and up, down, cross-conversion to and from 2K, HD, or SD
  • 4-Channel mode offers 4 x 2K/HD/SD channels of simultaneous conversion and processing, all within a 1RU chassis for multi-channel high-density delivery
  • Panel design provides straightforward operation in single channel or four channel mode
  • All four VIDx buttons under Channel Select are lit up in four channel mode
  • VID1 is lit and VID2-4 are off in single channel mode
  • Legacy signals and archival material need to be integrated into the 4K environment
  • 4K sources need to be down-converted for current 2K/HD pipelines
  • Supports up, down, cross-conversion from SD, HD or 2K over 12G/6G/3G-SDI video to 4K or UltraHD video and back
  • Supports both Quadrant (Square Division) and 2SI (Two Sample Interleave) output formats
  • Hardware conversion technology ensures better image quality for your productions
  • Utilizes standard BNC as well as optional SFP inputs and outputs to integrate easily into a variety of workflows and facilities with support for SDI workflows all the way up to 12G
  • BNC and Fiber inputs and outputs accept 4K/UltraHD/2K/HD/SD resolution SDI signals in single channel mode
  • 2K/HD/SD inputs can be routed to multiple locations simultaneously without the need for any external signal distribution in four channel mode
  • Looping reference input allows the synchronizer to be locked to your house reference signal for rock-solid stability
  • Digital audio can be disembedded and embedded between SDI, MADI, and AES for an array of routing possibilities
