                                Studio / Sync

                                In this submenu, define how flashes are to be triggered:

                                RFS on The trigger signal is transmitted by radio.
                                RFS off No trigger signal via radio.
                                Studio address Set a number between 1 and 99.
                                You must also set the selected number on your broncolor RFS radio transmitter.
                                If you switch to a different studio address, you may experience unwanted flash firings or radio interference*.
                                Lamp address

                                Lamp address:

                                The control range is 1 to 40.

                                The broncolor RFS 2.1, RFS 2.2 and RFS 3 radio transmitter systems allow you to control several groups of flash devices (one after the other).

                                The assignment to groups is based on the lamp address (this also applies to the bronControl app).

                                 

                                For more info, check out the relevant operating instructions:

                                •    RFS 2.1
                                •    RFS 2.2
                                •    RFS 3
                                •    bronControl app

                                The photo cell sensitivity is low.

                                The photocell sensitivity is high.
                                Cell off No flash triggered by light pulse.

                                 

                                *In the event of problems and undefined malfunctions of broncolor RFS devices, strong frequency interference may be disrupting radio communication between the devices. In this case, find a better location for your devices to avoid possible frequency interference from baby monitors, video bridges, microwaves, cordless DECT phones, WLAN or Bluetooth devices, or use a different studio channel.

                                If you set the same studio address on several broncolor flash units (and on the RFS radio transmitter), they will all respond to the commands from the radio transmitter.

                                RFS and cell can also be active at the same time.
                                Alternatively, you can also trigger the flash via the built-in sync socket (wired method).

                                Tip:
                                The sync socket is always active.
                                The sync cables (item no. 34.111.00; 5 m) and (item no. 34.112.00; 10 m) can be plugged into the sync socket for triggering via cable. for triggering via cable.
