Description
AJA 4K/UltraHD to HD-SDI and HDMI Down-Converter
Scaling Converters
Overview
AJA’s 4K2HD down-converts professional SDI 4K/UltraHD signals to HD resolution using AJA’s high quality scaling for cost effective monitoring and conversion. 4K2HD’s HD-SDI and HDMI outputs are both live all the time, producing fantastic looking HD images for on-set monitoring or direct-to-air broadcast. 4K2HD outputs SDI and HDMI simultaneously. 4K2HD supports high frame rate (HFR) 4K inputs at 50 and 60fps and gets converted to HD outputs at 50 and 60fps for accurate viewing. 4K2HD’s configuration options can extract an HD resolution image from the 4K input to provide a one-to-one pixel image for 4K focus checks on HD displays. Configuration can be set remotely via AJA Mini-Config software control over USB.

Real Time Down-Conversion
4K2HD uses real time processing and AJA’s high quality scaling algorithms to down-convert professional 4K or UltraHD signals using four SDI connections to HD resolution, producing fantastic looking HD images for on-set monitoring or direct-to-air broadcast.
Simultaneous HD-SDI and HDMI Outputs
4K2HD’s HD-SDI and HDMI outputs are live all the time, allowing use of both professional SDI monitors as well as low cost HDMI monitors simultaneously. No matter what monitors you have on hand, 4K2HD can use them for on the spot 4K viewing.
High Frame Rate Support
Many 4K productions are opting for higher frame rates of 50 and 60fps. 4K2HD supports high frame rate (HFR) 4K inputs and converts the HD output to a matching frame rate for accurate viewing so what you shoot is what you see.
Center Cut Extraction
4K2HD can be configured to extract an HD resolution center cut from the 4K input. This provides a one-to-one pixel image that can be used to check focus on 4K shoots without the need for a full 4K monitor.
USB and Mini-Config Support
AJA’s free Mini-Config software can be used with any USB enabled AJA Mini-Converter and provides an easy to use graphical interface with detailed information about the current input and output formats. Control all the parameters of any supported AJA Mini-Converter as well as loading firmware updates from AJA that add new features and functionality.
Universal Power Supply
All AJA Mini-Converters ship with a universal power supply that includes international plug connections for use around the world.
Compact and Portable
AJA Mini-Converters are small enough to fit behind a monitor, in the back of a rack, or directly on a camera rig. A locking power connector can’t accidentally pull loose and an optional P-TAP power cable allows for battery power in remote locations.
