Acute2 twin
12
The Acute2 twin is used to obtain even shorter flash duration,
very 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.
If you require shorter flash duration and you for example need
1200 Ws, you connect the Acute2 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 Acute2 head is used.
The flash duration at 1200 Ws with an Acute2 head is 1/560
while it is only 1/1000 with an Acute2 twin.
If, on the contrary, you require faster recycling, you power the
Acute2 twin with 2 Acute2 generators. The recycling is faster
since each generator need to recharge less energy.
To get 4800 Ws from one head you connect the Acute2 twin to
two Acute2 2400 generators.
Flash duration and recycling for an Acute2 twin at a certain
power setting - for example 1200 Ws - compares with a Acute2
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).
