The AD200 has 3 flash modes: Manual, TTL, and Multi (Stroboscopic). Manual outputs the user's choice of power, modeling light, first or second curtain sync, etc. Multi controls the stroboscopic rate up to 90 times (90 Hz). TTL takes advantage of the flash head's built-in X1 receiver. Optional TTL transmitters are available for Nikon, Canon, Sony, Lumix, and Fujifilm cameras. They will also detect a separately purchased LED head. The 32-channel wireless system controls flash mode, first and second curtain sync, High-Speed Sync up to 1/8000 second, power level, modeling lamp, and ready beeper at distances up to 328'. Firmware updates are obtainable on the Godox website.
