levels. When turning on the device, the display shows programme "0" and display “0”. Press
one of the numeric keys to select a particular chaser programme (see diagram below).
LPTCX401 GB 3
The master fader controls all outputs at the same time.
The chaser speed can be adjusted as follows :
Select speed 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E or F with the ▲ and ▼ keys. The selected
speed is displayed for ± 3 seconds. Consequently, the display will show the number of the
programme currently selected.
The direction of the chase can be inverted by pressing the key of the programme currently
installed. Hold the AUTO key to change the direction automatically.
The fade adjustments allow you to adjust the luminous intensity of each individual channel :
from OFF to 100% ON. You can also use the master fader to this end, but the master fader only
allows you to adjust the luminous intensity of all channels at once.
SOUND-CONTROLLED MODE
Speed 0 and programme 0 are always selected upon activation of the device. Switch to audio
mode with the SP/AU key (audio LED indicator lights). The chaser speed is now controlled by
the built-in microphone or by the external audio input AUDIO IN (20 in figure page 3).
