Slave Sync operation
When ‘SLAVE’ is shown in the Sync/Air setting section [25], the B2 unit senses the flash
release, as well as IR signals from most IR sync transmitters.
To activate slave sync, press the SYNC button [6] until ‘SLAVE’ is displayed.
Cable Sync operation
Sync via cable is possible in all sync modes. Connect a sync cable from the camera or flash
meter to the Sync Connector [15].
Modeling light
To turn on/off the modeling light on a lamp head, press the corresponding MODEL button
[9] or [12].
The modeling lights are automatically turned off after a settable period of inactivity (1-30
minutes).
1. To set the timer, press the SET button [7] until ‘SET TIMER’ is displayed.
2. Turn the ENERGY/SETTINGS dial 2 [14] to change the time.
Select freeze/normal mode
The B2 unit can operate in two modes to maximize the versatility in different shooting
situations.
•
Normal mode: Optimized color temperature stability over the entire energy range.
Best option for most types of shots.
•
Freeze mode: Optimized for shortest flash duration. Best option for shots where the
flash is used to freeze fast action. The color temperature might deviate and become
slightly bluer. The flash duration increases when two lamp heads are used.
Toggle between Freeze and Normal mode by pressing the MODE button [10].
