The KLA12 is part of the QSC KLA Line Array series. These arcuate, powered loudspeakers are known for generating sophisticated sound with relentless power in a user friendly line array system. Load in and be ready for sound check in no time with the unique Lift, Click, and Play design—the KLA12 may be either ground stacked or flown. This fixed system can be deployed as part of a portable touring sound system, or installed permanently in arenas, theaters, or places of worship and congregation. Pair the KLA12 and KLA181 in any combination of 5 with a daisy-chain XLR configuration for complete gain control from one remote pot.

Sound engineers will enjoy premium power efficiency and can run any combination of 5 KLA models on one 15 amp/120V electrical circuit. QSC has integrated an Auto Standby feature to put the speakers in standby mode after five minutes of output inactivity. When signal returns, the 500 x 500 Watt power amp module will re-engage and is capable of instant output. Power is delivered by powerCON in/thru connectors and the loudspeakers are housed in a durable ABS box that’s both rugged and light weight, resulting in hassle free operation and minimal maintenance.
