The "mod" key (15) switches on the modelling lamp for all connected lamps. When switched on, the blue LED next to the "mod" key lights up. The lamps have also an additional modelling lamp switch. Furthermore, it is possible to operate the modelling light proportionally (section 6.1) and adapt it to the various maximum outputs of broncolor power packs.
Pressing the "mod" key (15) (for 1 s) when the modelling lamp is on, will give direct access to the "full" mode. To return to the previous mode briefly press "mod" again.

Proportionality
The modelling light brightness can be set proportionally to the flash intensity. Stages prop1, prop2, prop3, prop4 and prop5 are used to adapt the modelling light brightness of power packs with different output. The setting "modelling light proportional" duly allows for the output set, the number of lamps as well as a possible asymmetrical energy distribution of the
Scoro power packs. Proportionality is guaranteed if the identical operating mode has been set for all power packs. The higher the digit, the brighter the modelling light.

The following operating modes are possible:
"propmax" → When working with only a single power pack (in asymmetrical operation); using the setting "propmax", the modelling light of the lamp with the highest flash energy operates at full output, and the other lamps will be proportionally dimmed, in accordance with their power settings.
"full" → All lamps with full modelling light, independent of flash output, type of power pack and output distribution.
"low" → Lighting level reduced for all lamps to reduce power consumption and extend the service life of the halogen lamps.
"prop1-prop5" → These levels allow adapting the Scoro units to the proportionality of other broncolor power packs.

Note: If a power pack is used with less power, it is known that the halogen modelling light is relatively weak and yellowish. To solve this problem, all broncolor

Reduced modelling light
To avoid overloading the mains supply (AC-line), the 100 - 120 V versions of the power packs reduce the modelling light intensity during charging. You can clear this factory-installed feature if the power rating of the mains supply (AC-line) is sufficient - see setting possibilities of the dimmer in section 14.11. When working on poor-quality mains supplies (AC-line) you can also slow down the charging rate with the additional function "charge time" – this reduces the risk of blowing the supply fuses (section 14.10).¨ During fast charging of Scoro A2S and A4S, the modelling light is dimmed, with the exception of the lamp with the highest power, to avoid overloading the mains supply, even when no reduction / dimmer was set (section 14.11).
 

Modelling light switch on lamp
The switch on the lamp is used to switch the modelling light on and off. To avoid damage to the lamp filament, always switch off the modelling light before moving the lamp.
