Profoto 1200 manuale d’uso

Acute2 manual Profoto, Stockholm, Sweden.[...]

W ar ning Profoto generators and lamp heads are parts of a complete professional lighting system. Please read the instr uction manual carefully before use. Flash tubes and modelling lamps emit considerable heat and may cause injur y if not handled properly . Note, always unplug the lamp cable from the generator before changing the modelling lamp or[...]

Thanks for showing us your confidence by investing in an Acute2 system. For more than three decades we have sought the per fect light. What pushes us is the conviction that we can offer even the most demanding photographer yet better tools. Before our products are shipped we have them pass an extensive and strict testing pro- gram. We check that th[...]

” A photographer ’ s tools are a natural part of the crea- tive process. Like a painter ’ s br ush, an artist ’ s chisel or a musician ’ s instr ument, their form and design should reflect their function, they should have the right feel, and they should be aesthetically pleasing ” . Profotos founders Eckhard Heine och Conny Dufgran, At [...]

7 The Acute2 series The system chart shows how the wide Profoto line of accessories fit together with generators and heads. R eflectors and heads can be combined in a number of varieties. The common denomi- nator is the lamp head diameter , which is the base of the Profoto line of products. The lines indicate the possible combinations that Profoto [...]

The flash heads 10 All Profoto lamp heads are designed for maximum light shap- ing purposes. The light source (both the flash tube and the mod- elling lamp) is mounted high and free in the flash head. This makes it easier for you to adjust the light and use your creativity . The flash head has a built in holder for the umbrella. The reflectors lock[...]

11 The Acute2 head is fan cooled and it has an automatic voltage selector for the fan. The dimmer controlled modelling light is powered directly from the mains and it is therefore important to check that the rated voltage for the lamp corresponds with the mains supply . A 250 W E11 Mini-can halogen lamp is included in standard deliveries. The Acute[...]

Acute2 twin 12 The Acute2 twin is used to obtain even shorter flash duration, ver y quick recycling or to fire 4800 Ws out of one single head. An Acute2 twin has two flash tubes. As the flash duration is shorter at low power switch settings, and as only half of the desired power is used in each tube, consequently shorter flash duration is obtained.[...]

The Acute2 ring is an entirely mobile source of light. The interior diameter of 100mm provides plenty of space for pro- fessional camera lenses. Since the camera holder can be tilted for ward and backwards, as well as upwards and downwards, most cameras can be attached. The Acute 2 ring gives a shadowless light and it makes an excellent source of l[...]

16 W arning! Never use ordinar y household extension cords to extend the length of the power cable. They may overheat. Contact your Profoto distributor for proper equipment. Connecting lamp heads One, two or three lamp heads can be connected to the sockets marked A, B and B (15). When connecting the lamp plug, align the white dots on the plug with [...]

17 Energy distribution The energy can be controlled over a 6 f-stop range or 7 when using 2 heads connected to the B sockets. The energy output through the outlets A (17) and B (19,20) is controlled by the A+B / A<->B switch (13), the switches A and B (12+14) and the dial BRACKET (15). The nominal energy of the flash unit is divided equally i[...]

21 Energy Control With the dial BRACKET (15) the total energy can, irrespective of the energy distribution, be reduced to 1/4, i.e. two f-stops. The flash duration, recycling and colour temperature is affect- ed by using the dial BRACKET . When using the bracketing dial (15) to reduce the energy you need to dump excess energy by pushing down the te[...]

22 Charging and recycling Check that the voltage selector (7) and the frequency - selector(8) matches the mains supply voltage. T urn on the main switch POWER (1). The recycling time is ver y short. V ariations may occur depend- ing on the selected flash energy and the mains power supply . The shortest recycling time is obtained with low flash ener[...]

24 Gas generator Most gas generators with an output of 2000W or more can operate an Acute2 generator . Please note that you must use a ProGas2 unit between the gas generator and the Acute2 generator to prevent damage to these two units if the gas generator operates at 230V . For more detailed information please see below or contact your local Profo[...]
