AJA Io 4K

AJA Io® 4K

Io 4K capture and output hardware offers a full set of professional video and audio connections with support for the latest 4K and UltraHD devices and High Frame Rate workflows. The powerfule Thunderbolt 2 interface enables Io 4K to handle a wide range of formats from SD to HD, UHD and full 4K over both SDI and HDMI and support 4K frame rates up to 50p/60p. With full-sized BNC connectors for 4K input and output as well as HDMI in and out, Io 4K can handle professional 4 x SDI 4K signals as well as capturing and outputting 4K over HDMI for use with more affordable 4K equipment. 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.

Io 4K features full 10-bit, broadcast-quality, motion adaptive SD to HD up-conversion, HD to HD cross-conversion, HD to SD down-conversion, and automatic HD/SD 12-bit component analog output. Since all conversion functionality is hardware-based, it's available on ingest or playback.

Thunderbolt 2 technology provides an incredible amount of bandwidth on a single Thunderbolt cable. Io 4K capitalizes on this increased capacity to allow up to 4K signals at frame rates up to 50p/60p 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.
