HDR

 BOX

 

 

 

The HDR (High Dynamic Range) module in the software enables you to control both LG2 lamps of the 

HDR box. The upper lamp is switched on with button [1] and the intensity controlled with a slider or an 

input field [2]. The same applies to the lower lamp, buttons [3] and [4].  

For both lamps separate sequence lists are available. Activating the sequence or looping functionality 

(

) applies for both lamps. Enter start 

and end times as well as the intensity from 0

…

100 %. 

Take into account that switching the LG2 on and off lamps takes 1

…

2 s, thus shorter periods are not 

advisable and may be omitted in the sequence player.

The module for the timecode display (

chapter 2.2

) offers two operating modes: timer and counter. 

Switch between the modes with menu [1]. 

Timer mode

: 

Start and stop the timecode with the 

start/stop

 button [2].  

Clicking the reset button [3] resets the timecode display to 00:00.000.
