Professional Connectivity

The latest Thunderbolt 2 technology allows even greater bandwidth between host computer systems and properly engineered Thunderbolt devices. AJA’s Io 4K takes full advantage of this improved throughput to allow capture and output of video signals from SD to 4K and everything in between. Io 4K supports 4K, UltraHD, 3G-SDI, Dual Link, HD-SDI and SD-SDI as well as UHD and HD over HDMI 1.4a for both capture and output. A dedicated, real time, always-on HD-SDI output allows Io 4K to simultaneously output to HD monitors when working at 4K or UHD resolutions, providing cost-effective monitoring options in addition to full resolution outputs.

Futureproof

HD SD Io 4K supports your current SD and HD workflows and provides a path to move to higher resolution productions whenever the need arises. The real time down-converter also means you can work at higher resolutions and easily create lower resolution deliverables without the need to recapture or re-edit – all at a size that’s easy to take on-set or in the field. Use Io 4K to capture AJA Raw over SDI at 4K up to 60fps to provide outstanding post production quality for even the most demanding color or visual FX requirements.

Powerful

Thunderbolt 2 technology increases the available bandwidth that can be carried on a single Thunderbolt cable. Io 4K capitalizes on this increased capacity to allow up to 4K signals to be captured and output. With dual Thunderbolt 2 ports, Io 4K can daisy chain additional devices together such as high-resolution displays and high-capacity storage for a complete, portable solution that’s powerful enough to meet the demands of professional production

AJA io 4K Connectors

Compatible

AJA’s industry-proven drivers and application plug-ins provide tight integration with leading post- production and delivery tools such as Apple Final Cut Pro X, Adobe Creative Cloud, AJA Control Room, Telestream Wirecast 5 and more. Io 4K gives you the flexibility to use the software tools that are appropriate for your workflow while maintaining consistent, high-quality hardware capture and output that’s ideal for your workflows now and into the future.

Monitor 4K in HD

When working at 4K resolutions, Io 4K outputs a high-quality HD-SDI down-converted signal on a dedicated BNC connector. This HD signal can be used to output 4K projects directly to HD recorders for broadcast and for easy viewing of 4K images on HD monitors during post-production.

Integrated Audio

Embedded 16-channel SDI and 8-channel HDMI audio are supported as well as analog audio outputs via a standard DB-25 connection. Stereo monitoring is also possible with 2 x RCA outputs and a front panel mini-TRS headphone jack.

Sync up

Io 4K can be locked to an external reference for integration into larger productions, or feed LTC in and out to ensure footage captured with Io 4K has the proper timecode.

Machine control

An RS-422 port allows control of tape decks for frame-accurate captures and layoffs.

Extensive software support

AJA hardware is supported by an extensive list of professional software for editing, visual effects, graphics and more allowing the same AJA device to be used by many different applications on the same system. In addition, AJA provides several free applications that enable you to utilize the power of your AJA hardware even without having to run a particular software package. This allows you to create unique workflows without tying up valuable resources unnecessarily.
