In 10-Channel and 17-Channel Modes these settings also determine the base color temperature of
the fixture’s white light output. In these modes you can use color mixing on top of this color
temperature.
Dimming curves
Four dimming modes are available:
LINEAR
The increase in light intensity appears to be linear as DMX value is
increased.
SQUARE LAW light intensity control is finer at low levels and coarser at high levels.
INV SQ LAW
(Inverse square law) light intensity control is coarser at low levels and finer
at high levels.
S-CURVE
light intensity control is finer at low levels and high levels and coarser at
medium levels.
To set the fixture’s dimmer curve, select DIMMER CURVE from the PERSONALITY menu and
press ENTER to confirm. Use the UP and DOWN buttons to select the desired mode. Press
ENTER to save your selection.
PWM Frequency
Sets the frequency of the PWM dimming used on the fixture. It can sometimes be necessary to
change this if flickering is seen on TV cameras running at a high shutter speed.
The PWM frequency settings available range from 600 Hz to 2400 Hz. The default frequency is
1200 Hz.
No Data Mode
This option sets what will happen when DMX data is not present.
To set No Data Mode, select NO DATA MODE from the PERSONALITY menu and press ENTER
to confirm. Use the UP and DOWN buttons to select:
BLACKOUT
– If data connection is lost, fixture blacks out.
HOLD
– If data connection is lost, fixture obeys the last DMX commands received on all
channels (default).
Press ENTER to confirm.
Cooling Mode
This option sets whether cooling fan speed is regulated depending on fixture temperature or
whether the cooling fans run at a constant speed.
To set cooling mode, select COOLING MODE from the PERSONALITY menu
and press ENTER
to confirm. Use the UP and DOWN buttons to select:
REGULATED FANS
– Fan speed is controlled by fixture temperature. Fans only run at the
speed necessary to keep the fixture within its normal operating temperature range. Light
output is not reduced unless full fan speed is not enough to keep the fixture within its safe
operating temperature range.
FULL
– Fans are set to constant full speed. Light output is not reduced unless full fan speed is
not enough to keep the fixture within its safe operating temperature range.
LOW
– Fans are set to constant low speed. The maximum light output available is reduced by
approx. 15% and fan noise is significantly reduced.
