AC Mains Connections

The LA108 and LA112 loudspeakers feature dual powerCON TRUE1 AC connectors 
to support daisy-chaining multiple loudspeakers 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. 
The benefits of the powerCON TRUE1 connector are:

• 20 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 source is switched on.

Daisy-Chaining with Power Cable Jumpers

The LA108 and LA112 loudspeakers feature loop-thru power connection using 
powerCON TRUE1 connectors. The powerCON TRUE1 cable and connector 
system is rated for a maximum current draw of 16 amps. In most countries, this 
is sufficient to power a maximum of six (6) LA108 or LA112 loudspeakers from 
a single connection to the AC mains supply (see chart below for more details 
by country voltage).

When not in use, the powerCON INLETS and OUTLETS connectors located 
on the loudspeakers' rear panel should be covered by the available weather-
resistant flaps.

Neutrik powerCON TRUE1 loop-thru cables are not included with LA108 and 
LA112 loudspeakers but may be purchased separately from most professional 
audio equipment suppliers or from QSC.

Compatible QSC Accessories

• LA-KIT-J (International Jumper Kit): two 60 cm PowerCon TRUE1 jumpers and two 60 cm EtherCON jumpers,  

1.5 mm

/H05VV cables

• LA-KIT-J-NA (North America Jumper Kit): two 24-in PowerCon TRUE1 jumpers and two 24-in EtherCON jumpers,  

12 AWG/SVT cables, NEC compliant

WARNING!: 

 

The amplifier AC mains power is present in the loop-thru cables. If the AC mains is connected to one 

LA108 or LA112 loudspeaker, electrical power is present on all connected loop-thru cables.

WARNING!: 

 

Do not connect more than six (6) LA108 or LA112 loudspeakers together using the jumper power cables 

(one AC mains power cord and five jumper cables). When using jumper power cables, make all loop-thru connections 
prior to connecting to the AC mains power source.
