System Power
The LS118 power module does not include a power switch. This is done to prevent an array from being suspended and a
loudspeakers'/subwoofers' power switch inadvertently bumped or left in the off position. To power a subwoofer on/off, either switch
the AC supply at the source or twist the AC POWER-IN connector clockwise or counter-clockwise to power each subwoofer on/off.
For safety reasons, it is important to follow the proper power cable connection/disconnection sequence to power on or off
loudspeakers and subwoofers.
Proper power on/off sequencing can help to prevent undesirable sounds from being introduced into the loudspeaker/subwoofer
system (pops, clicks, thumps). Always follow the rule that loudspeakers/subwoofers are “last on, first off.”
WARNING!:
The LS118 employs 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
location of deployment.
AC Connectors
The LS118 Subwoofer features dual powerCON TRUE1 AC connectors to support daisy-chaining multiple loudspeakers/subwoofers
within an array or for ground-stacking deployments.
Neutrik powerCON TRUE1 AC connectors have become standard in the AV
production industry and are often found on lighting systems and portable LED walls.
PowerCON TRUE1 connector benefits:
• 16 Amp current capacity
• Safe connection/disconnection under load
• POWER-IN and POWER-OUT locking connectors can couple to create
extension cables — without the need for a separate barrel connector
• IP65 rating for ingress protection (once coupled)
Connecting to AC Mains
1. Insert the locking POWER-IN cable connector of the supplied power cable into
the INLET connector on the rear panel.
2. Twist the cable connector clockwise until it locks in place. Twisting the connector
also turns power on/off for that box (and any subsequent daisy-chained boxes).
3. Plug the other end of the power cable into the appropriate AC Mains power
source.
4. Array will power on automatically once the AC Mains power has been connected.
