Caution – Burn Hazard – Hot Parts!
Do not touch hot parts with bare fingers! Modeling lamps, flash tubes and certain metal parts emit
strong heat when used! Do not point modeling lamps or flash tubes too close to persons.All lamps may
on rare occasions explode and throw out hot particles! Make sure that rated voltage for modeling lamp

The light output can totally be adjusted over 11 f-stops (0.1-10.0) but the range is
depending on Mode Control [13] setting.
By setting the Mode Control [13] to FREEZE, the energy range of outlet A is restricted to
0.1-5.8 (1-54.4Ws). If both outlets (A and B) are used the maximum output from each
outlet is 4.7 (25.4Ws).The maximum output of outlet B is always limited to 4.7 (25.4Ws)
in FREEZE mode. FREEZE mode is configured to get extremely short flash duration. See
more in section Flashduration &Mode control.
By setting the Mode Control [13] to NORMAL,the energy range of outletA is restricted to
2.0-10.0 (3.9-1000Ws).If both outlets are used the maximum output from each outlet is

By setting the Mode Control [13] to MASTER, the energy level will be simultaneously
adjusted for outlets A and B. Either Control A [16] or Control B [17] can then be used to
adjust the energy level for both outlets.

The maximum modeling light in total for both outlets is 500 W. The modeling light is
automatically max 500W,regardless of the nominal effect of the lamp heads.
The Model Buttons [18] are used to turn on/off the modeling light for outlet A and B
respectively. When the modeling light is turned on, M is shown in the corresponding

Synchronization& Control throughProfoto Air
The ProfotoAir radio system is fully integrated in the Pro-B4 generator,allowing wireless
remote synchronization and control from the camera.ProfotoAir has the fastest wireless
transmissionofanywirelesssyncsystemandhasanoperatingrangeofupto300meters1.
For more info check www.profoto.com
For sync/control via radio, the Profoto Air receiver in the generator must be activated
and a radio channel must be selected. Eight (1-8) sync channels are available and each
channel can be divided into 6 (A-F) logic groups for remote control.The group selection
allows a large light bank with several lamp heads, for example the background light, to
be controlled as one light source.Channel/Group setting and activation of the ProfotoAir
receiver is reached from the Sync Control [10].
