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 into

two groups, A and B, and the two groups can either be

combined or separated with the A+B / A<->B switch (13).

The energy in group A is controlled by the A-switch (12) and

the energy in group B is controlled by the B-switch (14).

In each group the energy can be halved or quartered.

Please see panel for details.

Below you will find detailed description on how to control

the energy if you use one, two or three Acute2 heads or if

you use a Acute2 twin.

Always start with settin g the BRACKET dial(15) to max,

the A- and B switch at full and the A+B / A<->B switch

(13) in position A+B. You now have maximum energy.

Full f-stop changes are done with the A- or/and B-switch.

Fine adjustments or further f-stop reductions are done with

the BRACKET dial.
