Universal Compatibility:
Thunderbolt™ 3 via USB-C

Io X3 Plus provides two Thunderbolt 3 ports for true Thunderbolt flexibility.

Thunderbolt 3 doubles the speed of the previous Thunderbolt 2 standard with up to 40 Gps of throughput and utilizes the universal USB-C connection standard for true simplicity over a single cable for today's leading Mac and PC workstations and laptops.

Thunderbolt™ 3 features:

  • Thunderbolt™ and power on one cable
  • USB-C connector and cables (small, reversible)
  • 40 Gb/s: Thunderbolt™ 3 – double the speed of Thunderbolt™ 2


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 X3 provides this support for your 2K and HD HDR pipelines to HDMI and SDI compatible displays in software v16.2 with HLG and HDR10 support with HDR Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.3 and HD.

AJA Control Room software and Io X3 adds support for HDR metadata capture from an incoming SDI or HDMI signal. The captured .mov video file will have embedded HDR metadata, allowing the file to be played back at its intended dynamic range.

AJA Control Room software and Io X3 Plus also provides HDR Auto Playback Detection. Embedded HDR metadata in a recorded .mov file is read and used to automatically set the HDR format on the monitor(s) connected to the HDMI and/or SDI outputs.

Support for file-based .mov HDR outputs with metadata from Adobe Premiere Pro / Adobe Media Encoder HDR files is also available. Screening those rendered outputs is a simple and high-quality experience with AJA Control Room. Every frame is presented in its full-quality, at the timing intended, and with the proper HDR format set correctly and automatically.

v16.2 Desktop Software also offers HDR input from HDMI for capturing HDR gaming content and more.

Use Case: NLE Workflow for Io X3

Io X3 offers broad support for all major NLE applications, including Apple Final Cut Pro, Avid Media Composer and Adobe Premiere Pro with a host of practical and easy to use features, shown in this NLE workflow diagram. The Io X3 sits at the center of the NLE workflow, connected directly to the host laptop via super fast Thunderbolt 3. The NLE software is running on the host laptop, with the output of the time line being shown via both the HDMI port and the 3G-SDI port simultaneously, with support for HDR and SDR monitoring. The analog audio jack on the front of the unit provides easy headphone monitoring, whilst at the same time a standard Tascam DB-25 loom connects an analog mixer and microphone to the workflow, with the front panel VU meters responding to the independent channel levels. An AJA Ki Pro Ultra 12G is connected for real time recording of the NLE output to Apple ProRes or Avid DNxHD codecs for archive or hand-off. Whether editing promos, news footage, sports, long form content or any other demanding video environment content, Io X3 is your perfect partner.

Use Case: OBS Workflow for
Io X3

Io X3 is directly compatible with OBS Studio, offering a comprehensive toolkit for mixing live video and taking the program content out to streaming destinations. Io X3 again sits at the center of the workflow pictured opposite, providing the necessary video I/O for a 4 camera source program. Via Io X3's multi-channel support, the 4 HD cameras are connected directly to the 3G-SDI ports of the Io X3 which is connected via Thunderbolt 3 to the host PC or laptop. The host computer runs the OBS Studio software and allows you to view all incoming HD sources in a single multiview via the HDMI port to any display. Audio can be monitored via the built-in analog headphone port. The final PGM stream is output from our switched sources via the host computer.
