Fires the flash manually. The button also serves as the ready
light indicator, visually showing when the flash is 100% recycled.

Ready Light
5. 1/2 Proportional
Same as proportional, but modeling light begins at 1/2
power. This is especially useful when mixing 1200 and 2400
flash generators on the set.

Profoto D4 – Computer Control Panel D4
11
Designed from the ground up with the commercial
photographer in mind,the Profoto D4 offers automatic,
proportional modeling lights proportionality at the touch
of a button. Each of the four lamp head connections has
independent modeling light control, but the ability to turn
each individual modeling light off from the pack is only the
start. There are five different unique settings for the
modeling lights:
1. Smart Max Proportional
Regardless of where the power is set for each individual
generator, if several D4 generators are used, the heads of the
generator working with most power will automatically have
max. proportional modeling lights, and the heads of subsequent
generators will show the output ratio proportional to it.
2. Max Proportional
Regardless of where the power is set for each individual lamp
head on a single pack, the lamp head receiving the most power
will automatically have a full power modeling light, and
subsequent heads will show the output ratio proportional to it.
3. Max
Modeling light is on full power regardless of the flash output
settings.
4. Proportional
As the power is raised or lowered, the modeling light dims
or brightens proportionally to show a true lighting ratio
between the lamp heads.
Switching to normal recycle draws less current and extends
the recycling time. This is ideal when shooting at locations
that have low amp fuses.
Power Indicator Display
Controls the On/Standby function of the packs from the
computer.
Master Power Control
Often the fine-tuning of lights requires an overall power
adjustment. With conventional flash generators, raising
the power of all individual channels would require the
photographer to manually adjust each channel individually
by the same amount. With the new Profoto D4, the Master
Power control button makes overall power adjustments
quick and easy. Using the sophisticated software, it’s also
possible to adjust the power of all or different groups of D4
connected to a computer at the same time.
Memory Recall
Three presets allow you to record commonly used set-ups
directly in the generator’s memory for easy duplication in
the future. By locking-in all of the settings, the Profoto D4
remembers individual head power settings, modeling light
settings, as well as auxiliary features, like sequence and
delay. It stores them safely until you recall them for use or
erase them. In addition, after turning off and/or disconnecting
the generator from the mains, the last settings are stored
automatically. If the generator(s) are controlled via
a computer, only the computer memory limits the possible
number of recorded set-ups.
Allows the photographer to select the type of visual and/or
acoustical indication desired when the pack is fully charged.
