head is connected to B half the energy is obtained if the SYM/ASYM switch is in position A 1/1
(1/2), B 1/2. If the switch is in the position A 1/2, B 1/4 a quarter of the chosen energy is
obtained.
Two lamp heads: The energy chosen with the MASTER [13] control can either be distributed
evenly through the two lamp heads (the SYM/ASYM switch in the position A1/1 (1/2), B 1/2)
or twice as much energy (equivalent to one f:stop) through A as B (the SYM/ASYM switch in the
position A 1/2, B 1/4). At any change of energy with the control MASTER [13] the ready lamp
[8] is put out. When the light is out, this is an indication that autodumping or recharging is
in progress.
Choice of Modelling Light
Pushing the button MOD.LIGHT [11] turns on the modelling light. To save the battery the
modelling light is automatically turned off after 20 seconds. To have the modelling light stay on
for a longer period of time push the button two or three consecutive times, which will give 40 and
60 seconds respectively. For every period of 20 seconds when the modelling light is turned on the
battery capacity decreases by the equivalent of two flashes at full energy. The maximum mod-
elling light is 100 W even if a ProHead with a 250 W halogen lamp is used. A ProHead or old-
er heads - Pro-7, PB or PF - can be used. The modelling light is automatically dimmed down to
100 W regardless of the nominal effect of the modelling light. The efficiancy (output) is higher
when using a 100W lamp. We therefore recommend to always use a 100W lamp also in the
ProHead.The modelling light is constant and does not vary with the energy chosen.
Connecting Camera & Flash Meter
The two sync sockets [6] allow the camera and flash meter to be connected simultaneously. The 5 M
sync cord can be extended without limitations with sync extension cords. Further sync connections
can be made with the Profoto sync interconnection cable or by so called ”hard wiring”. A slave
signal from the photocell can be forwarded through this cable to another flash generator.
