Operation - LD Systems ICOA LDICOASUB15A Manuel D'utilisation

OPERATION

NOTE:
The LD Systems logo briefly appears on the display as soon as the speaker is correctly connected to the power supply and switched on. All settings
(e.g., Preset and Delay) resume the way they were as before the speaker was switched off. The speaker will be ready for use after completion of this
process, which usually takes one second.
MAIN MENU DISPLAY
The main display is activated during normal operation. It shows the master volume setting, the activated speaker preset, and the input levels of
channels 1 and 2 with peak display (see figure). Reduce the source device's output level (e.g., mixer) if the peak display shows that the input signal
is too high.
