The QSC KLA Series brings the power and sophistication of a line array system into an easy-to-use product significantly redefining the line array product category. With its simple Lift, Click and Play approach, KLA can be deployed in a fraction of the time required by comparable line array products. 

This fixed or "arcuate", active line array system is ideal for a wide range of portable and permanently installed applications ranging from live entertainment to houses of worship or other venues where a line array system is desired. 

The QSC KLA12 features a highly efficient 500 watt by 500 watt power amp module and features QSC's DEEP DSP algorithm - providing extended bass response by actively managing potentially damaging low-frequency transients - and GuardRail circuitry protection which prevents the amplifier module from unnatural and destructive clipping.
