Professional connectivity

Have the connectivity required for today’s variety of productions. Io 4K supports 4K, UltraHD, 3G-SDI, Dual Link, HD-SDI and SD-SDI as well as UltraHD and HD over HDMI 1.4a for both capture and output. The HDMI output is also able to accurately display HDR 10, HLG to support emerging HDR workflows.

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.

Futureproof

Io 4K offers broad and futureproof support for formats all the way from SD to 4K. The realtime down-converter also means you can work at higher resolutions and easily create lower resolution deliverables without the need to recapture or re-edit.

With applicable streaming software, you can utilize all 4x 3G-SDI connections for live stream switching from multiple input sources.

HDR

HDR or High Dynamic Range, provides the ability to display a wider and richer range of colors, much brighter whites, and much deeper, darker blacks than standard signals allow. This gives your imagery a more ‘dynamic’ look and allows for natural true to life colors to be communicated to your audience.

Io 4K provides this support for your 4K/UltraHD/2K and HD HDR pipelines to HDMI compatible displays in software v12.5 and above by offering HDR 10 support with HDR Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.3. Desktop Software v13 introduces HLG support over HDMI for the latest versions of Adobe Premiere CC.

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 postproduction.

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, compatible with Thunderbolt 3, 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.

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.

Workflow

Connect your digital sources via 3G-SDI to Io 4K for capture to a wide variety of formats.

Monitor via HDMI output (HDR10, HLG, Dolby Vision* and HDR10+*, and master to destinations using high quality professional SDI outputs, machine control and analog or tri-level reference. _{**Dolby Vision and HDR10+ integration available when using the AJA SDK}

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.
