Scoro A2 | A2S
Use the "/" keys (9.1,9.2,9.3) to control the flash energy (flash intensity) on each individual outlet (1, 2 & 3) within a range of 9 f-stops. The entire energy, however, cannot exceed 1600 J. A value of 10 in the digital master power display (12) indicates maximum intensity, 1.0 minimum intensity (3 joules). Whole numbers are full f-stops, decimals indicate 1/10 of a whole f-stop. Brief pressure on the keys "/" (9.1, 9.2, 9.3, 10) runs the power up (or down) by a 1/10 f-stop level, prolonged pressure by a full f-stop. The digital display (12) then blinks until charging or discharging has reached the newly selected level and the "test" key light (16) goes out. An acoustic signal announces that the new energy level has been achieved.

Scoro A4 | A4S
Use the "/" keys (9.1,9.2,9.3) to control the flash energy (flash intensity) on each individual outlet (1, 2 & 3) within a range of 9.9 f-stops. The entire energy, however, cannot exceed 3200 J. A value of 10 in the digital master power display (12) indicates maximum intensity, 0.1 minimum intensity (3 joules).
Whole numbers are full f-stops, decimals indicate 1/10 of a whole f-stop. Brief pressure on the keys "/" (9.1, 9.2, 9.3, 10) runs the power up (or down) by a 1/10 f-stop level, prolonged pressure by a full f-stop. The digital display (12)
then blinks until charging or discharging has reached the newly selected level and the “test” key light (16) goes out. An acoustic sound announces that the new energy level has been achieved.

Individual energy distribution (asymmetry) & flash cut-off
Scoro power packs incorporate an electronic flash cut-off system for all 3 channels. The units have three individual lamp outlets which can be controlled, with neutral colour (Enhanced Colour Temperature Control) over the whole range, and with asymmetry up to 6 f-stop intervals and independently of each other. The unit allows power selection in 1/10 and whole f-stop intervals.

Colour temperature control / Asymmetry (in case flash duration t 0.1 is optimal)
All Scoro units are equipped with an enhanced ECTC-process which ensures that no colour temperature shifts or double exposure can occur during individual power distribution. On partial power, the colour temperature of the set energy can be influenced by relative shifts in intervals of 200 K upwards or downwards (see section 14.5, "Colour temperature"). The control range of the colour temperature adjustment is increased when on reduced power. Due to the direct dependence of colour temperature and flash duration, t 0.1 is automaticallyadjusted.
