Modeling light
The Modeling Light Switch [9] is used to turn on/off the modeling light for channel A and
B simultaneously. When the modeling light is on, the Modeling Light Switch knob [9] is
illuminated.
The Modeling Light Control [7] is used to select one of four modeling light alternatives:
• PROP: The modeling light intensity for each lamp head is automatically adjusted to
correspond in proportion in-between the generators set energy and maximal energy.
• ½ PROP: The modeling light intensity is adjusted automatically in proportion as for PROP
when the energy level is changed, but with half modeling light intensity of the designated
energy. Half proportional modeling light is used when generators of different sizes are
used together; Pro-8a 1200 Air shall be set to ½ PROP and Pro-8a 2400 Air to PROP.
• MAX: The modeling lamp gets the maximal intensity, regardless of the flash light energy
settings.
• MAX PROP: Maximal proportional modeling light is used when maximal light is needed on
one channel (the one with highest energy level). The highest set channel will get maximal
intensity and the other will correspond proportionally. Therefore the modeling light may
change on a channel which is not adjusted.
If Pro Studio2 is used to control the generators, a Smart Prop func tion is available. It is similar
to the MAX PROP setting, but the intensity proportions match all lamps and generators.
Sync signaling
The Pro-8a generator can be synchronized with the camera in different ways; via cable,
via Photocell / IR-slave or via the Profoto Air radio system (LPA radio system available on
special order). Both systems can not be integrated in the same generator.
• The two Sync Connectors [2] allow the camera and a flash meter to be connected
simultaneously. The 5 meter sync cable can without restrictions be elongated with a sync
extension cable. The bidirectional optical isolated Profoto sync interconnection cable is
recommended to be used to prevent ground reference interference when connecting sync
cables between different generators.
• The Photocell/IR-slave [3] sense signals from most IR sync transmitters as well as from
other flash light as a Slave and synchronize the unit.
• The Profoto Air remote radio control system is integrated in all Pro-8a generators,
meaning that the generators are prepared to be synchronized or controlled either via Air
Remote, Air Sync or via the Profoto Studio 2 computer program and Air USB.
The Sync Control [5] is used to control the sync signaling:
• RADIO: The generator is set to sync via radio.
