AJA: The new UHD-equipped Ki Pro Ultra 12G recorder/player

It offers single-channel 4K/UHD at up to 50/60p for recording and playback to and from Apple ProRes or Avid DNxHR, with flexible connectivity options including 12G-SDI, HDMI v2.0 (with HFR 4:4:4 and HDR capabilities) and optional fibre input and outputs. Alternatively it provides up to four channels of simultaneous HD recording up to 1080 50/60p with independent ProRes profiles per channel. It supports high dynamic range, with HLG and HDR10 recording and playback.

“Demand for 12G-SDI solutions is soaring as production professionals strive to create more streamlined workflows with enough bandwidth to carry higher fidelity HDR, high frame rate and 4K/Ultra HD signals over a single cable,” said Nick Rashby, president, AJA Video Systems. “Building upon the same framework of the production-proven Ki Pro Ultra Plus, we’ve developed the next-generation Ki Pro Ultra 12G to offer recording and playback of the highest quality video signals with 12G-SDI connectivity to streamline recording and playback – whether on set, in live venues or within a broadcast studio.”

The unit can display multi-matrix HD video for up to four channels during record over SDI monitor out, HDMI out, and on the built-in display. There is also multi-channel audio support (up to 64 channels) via embedded SDI or HDMI, AES/EBU and analogue, with enhanced super out and front panel audio monitoring with media status and per channel audio metering.

Built-in Ki Protect ensures recordings aren’t lost in a power failure. It also has two 12v 4-pin XLR redundant power inputs, with one power supply included.

Its WebUI enables file transfer and remote monitoring, configuration and control via a standard web browser, with users able to control multiple units from a single web interface, ideal for multi-camera and synched recordings. It records to rugged, high-capacity AJA Pak SSD media, the same used on previous Ki Pro Ultra products. The compact 2RU high, half rack width unit costs $3,995.
