The Transmitter Freemask Set from Hensel comes with a transmitter for the camera and two special receivers, which only receive signals for the freemask channels (F1 - F3). The transmitter is compatible with the current Strobe Wizard Plus radio trigger, channel 1-3 + all. You can simply turn the existing flash units into freemask-ready equipment with the help of the freemask radio set.
Note! Please take this into account as the flash units for the foreground motif also need to be triggered.
