Thanks for showing us your confidence by investing in an Acute2 system. For more than three decades we have sought the perfect 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 program. 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 Acute/D4 head in particular offer you this possibility . The light source, both the flash tube and the modelling light, is placed high and free in the flash head. This makes it easier for you to adjust the light and use your creativity. The reflectors are moveable and lock easily into place. By moving the position of the reflector you can get a higher or lower concentration of light in the center or more of a flood light. This is not new, of course. Our flash heads have always been designed that way. What is new, however, is our new glass cover, which is designed to increase precision. The Acute/D4 head and the Acute/D4 twin are supplied with a frosted and UV-coated cover glass, which together with the flash tube, produce a colour temperature adapted to daylight colour film. There are glass covers with varying filtration, for greater diversity. The whole Acute2 system is modular. Every single reflector and accessory creates its special light and the unique Profoto focusing system offers you a possibility to create your own light with only a few different reflectors. "A photographer's tools are a natural part of the creative process. Like a painter's brush, an artist's chisel or a musician's instrument, their form and design should reflect their function, they should have the right feel, and they should be aesthetically pleasing".

Reflectors and heads can be combined in a number of varieties. The common denominator is the lamp head diameter, which is the base of the Profoto line of products. The lines indicate the possible combinations that Profoto equipment offers.

The light source (both the flash tube and the modelling 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 easily into place and by moving the reflector different types of light shaping is achieved. All Profoto reflectors and accessories fit the Acute/D4 head´s. A UV-reduced quartz flash tube is included with all Acute/D4 head´s. The flash tube has two metal pins. When removing a flash tube, pull it straight out of the sockets. When inserting a new flash tube, check that the trigger wire clasps properly around the flash tube (please see mounting instructions in package). In case the head overheats the modelling light automatically switches off. When the temperature has dropped sufficiently the modelling light will switch on again. Acute2 generators accept all Acute Alfa, Acute2 and the new Acute/D4 head and Acute/D4 twin. ATTENTION! Always control the model light via the head's dimmer if an Acute Alfa head is used and set the model light control of the Acute2 generator to "MAX". NOTE! Always unplug the lamp cable from the generator before changing modelling lamp or flash tube. Acute/D4 head The Acute/D4 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/ D4head 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 10 15 35 10 15 34 10 15 37 10 15 39 10 15 36 10 20 02 10 20 13 Glass Cover, frosted, UV-coated (standard) Glass Cover, frosted, extra UV-coated, -300°K Glass Cover, frosted, uncoated Glass Cover, clear, UV-coated Glass Cover, clear, extra UV-coated, -600°K Glass Cover, clear, uncoated 250W, 120V Halogen, Mini-Can 250W, 240V Halogen, Mini-Can 10 11 Acute/D4 twin The Acute/D4 twin is used to obtain even shorter flash duration, very quick recycling or to fire 4800 Ws out of one single head. An Acute/D4 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. If you require shorter flash duration and you for example need 1200 Ws, you connect the Acute/D4 twin to the B sockets on the Acute2 1200 generator and fire 600 Ws from each tube. The flash duration is shorter than if a standard Acute/D4head is used. The flash duration at 1200 Ws with an Acute/D4 head is 1/560 while it is only 1/1000 with an Acute/D4 twin. If, on the contrary, you require faster recycling, you power the Acute/D4 twin with two Acute2 generators. The recycling is faster since each generator need to recharge less energy. To get 4800 Ws from one head you connect the Acute/D4 twin to two Acute2 2400 generators. Flash duration and recycling for an Acute/D4 twin at a certain power setting - for example 1200 Ws - compares with a Acute/D4 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. The modelling light is a 500W Halogen with a Mini-can socket (E11). The flash tube has two metal pins. When removing a flash tube, pull it straight out of the sockets. When inserting a new flash tube, check that the trigger wire clasps properly around the flash tube (please see mounting instructions in package). 10 15 18 10 15 19 10 15 20 10 15 21 10 20 07 10 20 15 Glass Cover, frosted, UV-coated (standard) Glass Cover, frosted, extra UV-coated, -300 gr K Glass Cover, frosted, uncoated Glass Cover, clear, UV-coated 500W, 120V, Halogen, Mini-can 500W, 240V, Halogen, Mini-can Acute/D4 ring The Acute/D4 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/D4 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/D4 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. The maximum charge is 9600 Ws/minute. This means 4 flashes a minute at 2400 Ws, 8 flashes at 1200 Ws, 16 flashes at 600 Ws, etc. Changing flash tube is only to be done at a professional service station. Mounting the reflector: ·Remove the two ridged screws fixating the camera holder. ·Remove the four ridged nuts holding the outer and inner reflectors together. ·Run the lamp cable through the outer reflector and let the reflector slide into position. ·Reassemble the outer and inner reflectors using the ridge nuts. ·Reassemble the camera holder using the two ridged screws. 10 06 42 Softlight Reflector Ring 10 06 43 Close-Up Reflector Ring 12 13 Nomenclature 17.
