System Power
The LA108 and LA112 loudspeakers' electronic modules do not include a power switch. This is to prevent suspending an array with a
loudspeaker's power switch inadvertently bumped off, or left in the off position. To power a loudspeaker on/off, either switch the AC
supply at the plug source, or twist the AC POWER-IN connector clockwise or counter-clockwise to power each loudspeaker on/off
(ifAC power is connected).
For safety reasons, it is important to follow the proper power cable connection/disconnection sequence to power on or off
loudspeakers.
Proper power on/off sequencing can help to prevent undesirable sounds from being introduced into the loudspeaker system (pops,
clicks, thumps). Always follow the rule that loudspeakers are “last on, first off.”
WARNING!: The LA108 and LA112 loudspeakers employ a universal power supply, capable of operating the system
with input AC power voltages ranging from 100 – 240 VAC at 50 – 60 Hz. Make sure to only use the power cable that is
appropriate for the deployment location.
