Bowens® Mount Modifiers Modifying the light from your S1 is key to creating dynamic images. The S1 can be used with any light modifier with a Bowens® S-Type mount. To attach a Bowens® mount modifier to the S1, simply insert the three prongs of the modifier ring into the mount and rotate clockwise until you hear a click.
They will also not allow you to use HSS or TTL. A sync cable is included with your S1 and can be plugged into the sync port on the rear left side of the flash unit and the corresponding sync port on your camera.
Your S1 is packed with 500Ws of power. This power is adjustable over a 9-stop range and can be adjusted in 1/10th of a stop intervals. Use the power adjustment dial on the back of your S1 to adjust the power from 10.0 (full power) to 2.0 (lowest power) in manual mode.
CELL When using a multiple light setup with your Interfit S1 and a sync cord or a third-party remote, turn on the “CELL” button to activate the optical slave function. This will allow the light to be triggered by the light of your other flashes.
Mounting to a Light Stand Your S1 will mount to most standard light stands with a 5/8” stud. Unscrew the Stand Mount Knob until the mount fits onto the light stand. Make sure to turn the Stand Mount Knob until tight.
