User manual PROFOTO ACUTE 600E

[. . . ] We check that they pass the quality and capacity levels the most demanding photographers require. For this reason our flash equipment is the standard in most rental studios in New York and Tokyo and the most rented flash all over the world. The system consists of a variety of generators built and designed to meet the demands of the most demanding photographers on this planet. Yet the most important thing is the light you create and it is then essential that the system offers freedom to create your own light. [. . . ] The 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. The Acute2 head is supplied with a frosted UV-coated glass cover and a Zoom reflector. Combined with the UV-reducing quartz flash tube the frosted glass cover offers the recommended colour temperature for daylight type film. Distinctive colour temperature adjustments can be obtained by combining glass covers with different coatings. The following glass covers are available: 10 15 33 Glass Cover, frosted, UV-coated (standard) 10 15 35 Glass Cover, frosted, extra UV-coated, -300°K 10 15 34 Glass Cover, frosted, uncoated 10 15 37 Glass Cover, clear, UV-coated 10 15 39 Glass Cover, clear, extra UV-coated, -600°K 10 15 36 Glass Cover, clear, uncoated 10 20 02 250W, 120V Halogoen, Mini-Can 10 20 13 250W, 240V Halogen, Mini-Can 10. Acute2 twin The Acute2 twin is used to obtain even shorter flash duration, very quick recycling or to fire 2400 Ws out of one single head. 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. If you require shorter flash duration and you for example need 1200 Ws, you connect the Acute2 twin to the B sockets on the Acute 1200 e generator and fire 600 Ws from each tube. The flash duration at 1200 Ws with an Acute head is 1/320 while it is only 1/560 with an Acute2 twin. If, on the contrary, you require faster recycling, you power the Acute2 twin with 2 Acute generators. The recycling is faster since each generator need to recharge less energy. Flash duration and recycling for an Acute2 twin at a certain power setting ­ for example 1200 Ws ­ compares with a Acute head powered with 600 Ws. Since the modelling light is powered from the mains supply it is important to check that the rated voltage for the modelling lamp corresponds with the mains supply. When removing a flash tube, unfold the stainless steel ribbon before pulling it straight out of its socket. After inserting the new flash tube, lock the flash tube into place by folding the stainless steel ribbon around the clasp. 10 15 18 Glass Cover, frosted, UV-coated (standard) 10 15 19 Glass Cover, frosted, extra UV-coated, -300 gr K 10 15 20 Glass Cover, frosted, uncoated 10 15 21 Glass Cover, clear, UV-coated 10 20 07 500W, 120V, Halogen, Mini-can 10 20 15 500W, 240V, Halogen, Mini-can 11. Acute2 ring The Acute2 ring is an entirely mobile source of light. The interior diameter of 100mm provides plenty of space for professional camera lenses. Since the camera holder can be tilted forward 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 light in cramped areas, such as the interior of an automobile. Many fashion photographers also use the Acute 2 ring to find new angles and capture details. The ring flash provides a very distinct, directed light, but can be complemented by a soft light reflector, which increases the light source, thereby producing a soft light with little shadow. For close-ups, there is a reflector that focuses the light 50 cm in front of the camera lens. This means 4 flashes a minute at 2400 Ws, 8 flashes at 1200 Ws, 16 flashes at 600 Ws, etc. [. . . ] Connecting Camera and Flash meter Synchronise by connecting the sync cable from the camera or flash meter to the sync socket (11). The 5 metre sync cord can without restrictions be elongated with a sync extension cable. Sound signal The acoustic signal "beeps" when the unit is fully recycled. Automatic Safety Function If the unit is under intensive use with frequent flashing for an extreme long period of time, the recycling will stop completely. [. . . ]
