AJA LUT-box - Manual (Page 6)

LUT-box Mini-Converter v2.1r1 www.aja.com 6
Audio Integration Up to 8-channels of embedded SDI and HDMI audio output are supported. You can
select which SDI embedded audio input channels are used (Ch 1-8 or Ch 9-16), and can
choose to route all eight or just one pair of these channels to the HDMI output. Two
channels of analog audio output allow direct external monitoring without the need to
disembed the audio separately.
USB and MiniConfig
Support
AJA’s free MiniConfig 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.
DIP Switch Control DIP switches on the bottom of the unit allow local control of some features without a
computer. One of the DIP switches is a “Local/Remote” switch. When in the “Local” mode,
the remaining DIP switches support a subset of the user controls. When in the “Remote”
mode, the normal Mini-Converter non-volatile registers control the unit (as last set).
Universal Power Supply All AJA Mini-Converters ship with a Universal Power Supply that includes international
plug connections for use around the world.
5-year Warranty All AJA Mini-Converters are covered by a 5-year warranty and AJA's advanced
replacement policy. If a replacement is necessary, AJA will ship a new unit immediately
without the need to send the original unit back first, ensuring you are up and running
again as quickly as possible.

About LUT Data
Write and Read
The LUT-box has four areas that can store LUT data,1D LUT slots A and B, and 3D LUT slots
A and B. Externally accessed (via USB) LUT file data is written directly into a LUT-box slot,
where it acquires a proprietary internal data structure. The file name of the source of the
LUT data written into the slot is displayed on the MiniConfig LUT screen. Data residing in
one of the LUT-box slots can be read from that slot, and then be sent to an external
location via USB. When sending the data, you can select a LUT file format (.txt, .3dl, .lut,
.cube) for the data, and produce a file at that destination location that can be used with
other LUT-boxes and color management applications. This also makes it possible to
convert LUT files from one format to another. However, due to internal math rounding
errors, converted LUTs may not perfectly match each other, though any differences will
be extremely small.
