Slave mode with the mecablitz 45 CL-4 or
60 CT-4 additionally requires the use of the
SCA 3000C connecting cable (optional extra)!
2.2 Radius and maximum distance range in
slave mode
Since slave flash units are controlled by weak flash
pulses from the controller (master), the ambient
light level should be as low as possible. Moreover,
the sensor of the slave adapter should be directed
at the main subject. If, after firing the test flash,
there is no acknowledgement by one or more
slaves, then the rotary base of the slave must be
turned in the direction of the controller so that
renewed test flash firing triggers the acknow-
ledging flashes. For longer distances between con-
troller and slave the rotary base or sensor of the
slave should always face the controller.
Depending upon the ambient light level, the re-
flectance of the subject and the spatial conditions,
an action radius (distance from controller to slave)
of between 5 m and 10 m should be taken into
account. The maximum range, i.e. the maximum
distance between controller and subject, or be-
tween slave and subject, depends primarily on the
ISO sensitivity, the number of slave units used, the
selected aperture, filters and bounce diffusers (on
the mecablitz), the spatial conditions and the distri-
bution of the slave units within the room. It is
therefore hardly possible to give a generalized
statement concerning the range of a remote set-
up. Consequently, with regard to range, please
refer to the guide values listed in the technical data
of the operating instructions for the given flash
unit.
