NOTE ABOUT MEASURING COLOUR TEMPERATURE (CCT)
SWORD Series incorporate the innovative VELVETLight technology based
on high-power LED triplets + Fresnel lens + CPU control software to
obtain the wide range of calibrated colour temperatures combined with a
high colour rendering index CCT.
We
We must remark that traditional color meters still in use today are
designed for a full spectrum source such as incandescent lights and
therefore cannot be used to accurately read the correlated color
temperature (CCT) of the light emitted by VELVETLight LED light fixtures.
The eventual diversions to green display as CC05M or CC10M in hand-held
color meters are due to these unaccuracy on reading of the light emitted
by LED and must not be considered.
To
To precisely measure the light emitted by VELVETLight and other LED light
fixtures a spectrometer specially calibrated for LED sources must be used.
VELVETLight guarantees pure white light and correct colorimetry of the
light delivered by its high power LED luminaries which have been
calibrated in laboratory according to CIE 13.3-1995 international standards
for measurement of the CRI and chromatic coordinates (x, and CIE-1931).
The
The reliability of this digital equipment is supported by the calibration
VELVETLight has made in laboratory by spectrophotometer, which
precision is half-yearly calibrated according to the National Institute of
Standards (NIST) of the United States and of the Physikalisch-Technische
Bundesanstalt (PTB) of Germany.
In
In order that the advanced VELVETLight luminaries could be used together
with other light sources, we have accurately calibrated both the CCT and
the chromatic coordinates to match them with traditional light sources
following tungsten and daylight standards.
The digital Control Unit allows a further and precise green/magenta
correction.
VELVET SWORD series are LED panels housing 16 high power LED
(SWORD2) / 32 high power LED (SWORD4). They have been specially
designed and their colorimetry calibrated for professional photography,
cinematography and television industry use.

Once you have chosen the desired address number push the “32K/56K”
button to save the selection.
Keep in mind the following points regarding DMX control:
• VELVET DMX protocol uses 2 channels per fixture
• After the DMX address is entered the fixture will automatically assign
the following channel
•
• If you wish to control several VELVET fixtures at the same values you will
have to set them to the same address
• If you wish to control several VELVET fixtures independently you will
have to offset their address by 2 channels. Example
fixture1 address 001 -- fixture2 address 003 -- fixture3 address 005
When you connect your console to VELVET you will be able to control the
fixtures through 2 channels:
COLOUR TEMPERATURE From 2.7 to 6.5 (from 2700Kelvin to 6500Kelvin)
COLOUR TEMPERATURE From 2.7 to 6.5 (from 2700Kelvin to 6500Kelvin)
Fader=0 (2.7) means 2700Kelvin / Fader=100 (6.5) means 6500Kelvin
DIMMER
Do not use microphone cables or other general purpose two-core cables designed for audio
or signal use. They are not suitable for DMX 512. Problems due to wrong cabling may not
be immediately perceptible. Microphone cables may appear to work fine, but systems built
with such cables may fail or be susceptible to random errors. Cable must comply with
RS-485 DMX protocol (EIA485).
A DMX terminator should be plugged into the final, empty, OUT connector of the last slave on
the daisy chain. A terminator is a stand-alone male connector with a built-in 120 Ω resistor,
matching the cable characteristic impedance, connected across the primary data signal pair.
