Professional Connectivity: 12G-SDI and HDMI 2.0

Today's workflows demand speed, bandwidth and simplicity. Io 4K Plus supports 4K, UltraHD, 12G/6G/3G/1.5G-SDI, Dual Link, HD-SDI and SD-SDI as well as UltraHD and HD over HDMI 2.0 for both capture and output. The HDMI output is also able to accurately display HDR 10 and HLG to support emerging HDR workflows.

12G-SDI and HDMI 2.0 bring both power and simplicity to your projects, with the ability to use single cables for both input and output for the most demanding workflows. 12G-SDI is backwards compatible with SDI sources, covering all your bases through a single port. HDMI 2.0 allows high raster and frame rate capture and the ability to display the same to affordable and beautiful HDMI 2.0 displays.

Universal Compatibility: Thunderbolt™ 3 via USB-C

Io 4K 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 and port for today's leading Mac and PC workstations and laptops, ideal for Video and Audio I/O as provided by the Io 4K Plus.

Monitor 4K/UltraHD in HD

When working at 4K resolutions, Io 4K Plus 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.

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 Plus provides this support for your 4K/UltraHD/2K and HD HDR pipelines to HDMI compatible displays in software v14 with HLG and HDR 10 support with HDR Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.3 and HD.

v14.2 Desktop Software offers HDR input from HDMI 2.0 input for capturing PlayStation and PlayStation Pro game play and more.

Workflow

Connect your digital sources via 12G-SDI to Io 4K Plus for capture to a wide variety of formats. Monitor via HDMI 2.0 output (HDR10, HLG, Dolby Vision*), and master to destinations using high quality professional SDI outputs, machine control and analog or tri-level reference.

*Dolby Vision integration available when using the AJA SDK.

Integrated Digital Audio, Analog Audio Flexibility

Embedded 16-Channel SDI and 8-Channel HDMI audio are supported as well as analog audio inputs, outputs or both via a standard DB-25 connection.

Stereo monitoring is also possible with a front panel mini-TRS headphone jack.

With desktop software v14 analog audio can be configured for flexibility when needing to record voice overs and more with the ability to choose how the DB-25 connection on Io 4K Plus is configured:

  • 8-Channel, 24 and 16-bit D/A analog audio, 48 kHz sample rate, balanced, using industry standard 8x XLR on DB-25 breakout cable (cable not included)
