User manual PROFOTO PRO-3A

[. . . ] For this reason our flash equipment is widely used in rental studios in Paris, London, New York, and Tokyo and also the most rented flash all over the world. Some photographers can tell just from seeing a picture, if Profoto equipment has been used Professional photographers around the world have come to value Profoto's expertise in lighting and light-shaping. Our extensive range of Light Shaping Tools offers photographers unlimited possibilities for creating and adjusting their own light. Every single reflector and accessory creates its special light and the unique Profoto focusing system offers you the possibility to create your own light with only a few different reflectors. [. . . ] A clear "beep" will also sound to indicate that the charging is completed. This setting also enables the sound indicating that a switch is pressed or a control is turned. Speed control The versatile recycling speed settings make it possible to efficiently utilize the mains power supply by adjusting and optimizing the maximum possible speed and load without blowing fuses. The generator's amperage load from the mains power supply corresponds proportionally to the speed setting. The Speed Control [18] is used to select one of four recycling speed settings: · 25% The slow recycling speed is four times as long as the MAX recycling speed. This alternative shall be selected when the generator is connected to a mains power supply with weak fuses, when you are uncertain as to how well the mains power supply is fused and when weak gas generators are used for charging. It may allow tree or four generators to be connected to the same wall outlet or fuse group. · 50x The fast recycling speed is twice as long as the MAX recycling speed. This setting may allow two generators to be connected to the same wall outlet or fuse group. · 75% The extra fast recycling speed is slightly longer than the extremely fast MAX recycling speed. It reduces load by 25% and may prevent sensitive types of fuses to blow. A cold generator may not work properly or may even brake and will lose capacity (flash output). There is also a risk of failure because of condensation when a cold generator is moved to a warmer surrounding. Remember that the generator has a great temperature storing mass and will not adapt to the indoor normal surrounding temperature until after 1­3 hours. Never use a Pro-8a generator that has been stored in abnormal temperatures for more than 1 hour. A well insulated case or transport box will prolong the time of storage in abnormal temperature to 2 or 3 hours. Never operate the generator inside a case or transport box due to lack of ventilation. Never expose any flash equipment to wet or humid environments or extreme electromagnetic fields. www. profoto. com Pro-8a 2400 Air ­ Pro-8a 1200 Air 11 ready lamp/Test function The ready lamp and test button functions are combined. Pro-8a 2400 Air ­ Pro-8a 1200 Air 12 Additional information color Temperature The color temperature of Pro-8a is calibrated to correspond to daylight and, because of the PiPE (patent pending) technology, it remains perfectly constant and reliable from flash to flash and over the entire power range, regardless of the chosen power output and the number of flash heads used. This makes the Pro-8a generators perfectly suited for all kinds of critical assignments, even with high-resolution digital cameras and backs. In combination with all actual Pro flash heads and light shaping tools the Pro-8a generators give neutral and extremely stable color. Please note that other factors, like reflections from surrounding objects and ambient lights with non neutral color characteristic, may influence the light color temperature and spectra. Combining flash tubes and/or glass covers with different coatings can make distinctive color temperature adjustments if needed. [. . . ] Wireless remote control For Air Remote control, both radio channel and group have to be set. For wireless use with Profoto Studio 2 and AIR USB, only radio channel has to be set. The radio channel and group setting for the individual lamp head is shown separately in Flash Light Energy Display A [6] or B [17] as a radio channel number (1­8) followed by a group letter (A­F). 3. Turn Flash Light Energy Control A [8] or B [19] clockwise/ counterclockwise to increase/decrease the radio channel number. [. . . ]
