The KLA 181 features an energy efficient 1000 watt power module. A polarity switch controls low frequency directivity and its pole receptacle is capable of mounting up to 2 KLA12 2-Way Line Array Loud Speakers.

QSC’s DEEP DSP algorithm provides extended bass by actively managing low-frequency transients. GuardRail protection circuitry prevents the amplifier module from unnatural and destructive clipping. An auto-standby mode will auto-engage after 5 minutes of inactivity to save energy. XLR and PowerCon input and thru connectors provide connection versatility, while a Phoenix connector allows daisy-chaining.Add epic low end to your live rig, with a KLA181 subwoofer from QSC. This hard-hitting 1,000-watt active subwoofer features QSC’s amazing DEEP DSP algorithm, which smoothly shapes bass frequencies for maximum impact.

GuardRail protection allows the KLA181 to deliver maximum peak power, without overloading. That lets you keep the crowd amped up, without risking show-stopping shutdowns. The KLA181 sub also features both a balanced line-level XLR though jack and a locking AC power through jack – perfect for daisy chaining up to a set of KLA12 top boxes pole-mounted overhead.

KLA181 Subwoofer In addition to DEEP™ DSP algorithm, GuardRail™, Auto Standby, balanced line-level XLR input with an XLR “Thru” connector, Attenuation Control and LED indicators, the KLA181 subwoofer also includes a polarity switch for low frequency directivity control.

Rigging & Deployment
For maximum deployment flexibility, KLA loudspeakers can be either ground deployed or flown. As a ground stack, up to two KLA12 enclosures can be mounted over the KLA181 or the KW181 subwoofer via a threaded pole socket, or without a sub using an appropriately rated loudspeaker stand. Arrays of up to 480 lbs (218 kg) (with a maximum five KLA12 and two KLA181 enclosures) can be flown via the included M10 fittings or the optional KLA AF12 array frame.
