QSC KLA Line Array System (Discontinued)

The KLA12 features a highly efficient 500 watt by 500 watt power amp module. This efficient design enables up to five KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15 amp, 120 volt electrical circuit. It has a 90' x 18' nominal coverage angle and features a self contained rigging system. It is available in black or white.

The QSC KLA181 18 inch Subwoofer offers highly efficient power amp module in a 1,000 watt configuration. This efficient design enables up to five KLA models to be driven off of a single 15 amp, 120 volt electrical circuit. 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 includes a polarity switch to optimize summation between subwoofer and top-boxes. As an energy saving feature, the Auto Standby mode automatically engages after five minutes of inactivity but upon resumption of audio signal, the power module on the KLA will awaken instantly for immediate output.

The KLA loudspeakers incorporate 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. As an energy saving feature, the Auto Standby mode automatically engages after five minutes of inactivity but upon resumption of audio signal, the power module on the KLA will awaken instantly for immediate output.

In an installed application, multiple KLA Series loudspeakers can be "daisy-chained" for total gain control from a single remote pot wired to the on-board Phoenix-style connector. Additional power module characteristics on KLA include a balanced, line-level XLR input in parallel with an XLR "Thru" connector, PowerCon™ In and Thru connectors, Attenuation Control and LED indicators for Signal, Limit, Power and Standby status.

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.
