• The Godox smartphone app must be paired with a Godox A1 flash trigger via Bluetooth and then can be used to:
  • set the light outputs of each group of lights on each radio channel, including LED lights
  • provide control over multi-flash stroboscopic settings
  • use the smartphone's camera to take a shot and trigger the lights via the A1 transceiver
• When used in conjunction with a camera with an X1T transmitter, the X1T will need the August 2017 firmware which presumably allows a mode whereby the X1T transmitter's power settings are not used, but it is only used to trigger the lights when the camera fires - the power settings instead are controlled via the smartphone via an A1 transmitter
  • “To add C.Fn custom settings. The transmitter’s parameters that set by Godox APP are not changed. And the transmitter is only for triggering”

  • 600Ws powerful portable studio type LiIon flash giving GN 87m ISO 100 AD-R7 standard reflector
    • Compared to the Profoto B1, the AD600B¹⁾:
      • gives 1EV more power when using 7“ reflector and same spread of light (although same output when tested with Godox vs Profoto softboxes)
      • has shorter flash durations and less shot-to-shot variation in output level (B1 had +/- 0.1EV)
      • is lighter, smaller, much more affordable and with much more affordable lighting accessories
      • HSS works at all power ranges not just at the higher ranges
      • gives 500 shots on a full battery compared to only 200 shots
      • transmitter has a hotshoe on it whereas the Profoto one doesn't
      • can use an AC adapter
      • can use one or two onto a remote head to give 600Ws/1200Ws remote head output
      • has a variety of other TTL controllable flash styles whereas Profoto only has studio type flashes
      • but the B1 recycles faster with more accurate color (the AD600 color changes by ~300K at different outputs) and has a better head for applying gels
  • 11.1V 8700mAh LiIon battery pack attaches to rear of unit and takes 4hrs to re-charge but gives 500 full shots and recycle of 0.01-2.5sec (can attach an optional AC adapter after removing the battery)

  • flash duration 1/220th - 1/10,000th sec; strobe multi flash up to 100 times at up to 100Hz
  • NOT able to be mounted on camera - requires a light stand but does incorporate an umbrella holder (although need to buy the optional Godox reflector with umbrella slot in correct position)
  • can be hand held, preferably via the optional AD H-600 / H-600B remote flash head which is much lighter but does drop maximal power output by 1/3rd EV
  • optionally, if you own two AD600 units, you can combine the power output of each into one 1200Ws H-1200 head with a 1200W bulb to get an extra 0.7EV light compared to a straight AD600B or 1EV more compared to a H-600B
    • see https://www.youtube.com/watch?v=IO77XTfaFOI
  • optional PB-600 portable bag to help carry and operate the controls of the AD600 while using the H-600 head, and the bag helps to keep dust and rain from the unit
