NAB 2014: AJA has announced Kona 4, the latest generation of its professional desktop video and audio I/O cards.

Kona 4 supports formats from SD to HD, 2K and 4K with full 10-bit 4:2:2 and 4:4:4 colour spaces and offers support for high frame rate 4K/UltraHD up to 60p and HFR Ultra HD HDMI output.

Kona 4 features 10-bit scaling and a hardware downstream keyer, as well as bi-directional 3G-SDI connections that can be used for input and output.

The HDMI 2.0b monitoring output allows high frame rate Ultra HD monitoring.

Additionally the card offers LTC I/O, genlock input, RS-422 control, configurable 3 x BNC HD/SD analogue video output and 8-channel AES audio I/O

AJA President Nick Rashby said: Kona 4 represents a huge breakthrough, delivering cost-effective high frame rate 4K at up to 60p to the desktop.

“Upon release, Kona 4 has already been integrated into top of the line product offerings from Autodesk, Cisco, Codex and Colorfront, which is a huge testament to its performance and reliability.”
