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).
