The transmitter for using the freemask system to create quick and easy cut-outs. Designed for Hensel units with a built-in freemask radio receiver, such as the Expert D, Nova D/DL, Porty L, or Integra Plus series. While this transmitter is specifically designed for freemask applications, it can also be used for standard studio work (subject to minor limitations regarding the firing rate). The freemask transmitter sends a secondary radio signal via the specific F-channels required for freemask background illumination.

When used with compatible built-in radio receivers, it allows you to adjust flash output and control the modeling light. You can operate using three distinct channels plus an "All" channel. The transmitter is compact and lightweight, and can be easily mounted onto the camera's accessory shoe. Alternatively, you can use the included sync cable.
