In the KLA12, QSC gives you a modular line array speaker with a "Click and Play" design. KLA12s can be coupled easily to form arcuate line arrays -- connect as many boxes as you need. With just five of these boxes, you can get complete 90-degree vertical coverage to send sound evenly across a big audience. QSC KLA12 speakers are ideal in situations ranging from parks, to large halls, to houses of worship.

Modular 2-Way Powered Design

Each speaker module itself is a two-way design setup with a 12-inch low-frequency transducer and a 1.75-inch compression driver. Each KLA12 employs a super-efficient 2 x 500-watt power amp, which allows you to combine up to link up to five KLA12s and/or KLA181s (QSC's complementary 18-inch KLA subwoofer) and drive the whole array off a single 15 amp, 120 volt electrical circuit.

Easy as Possible to Assemble

The QSC KLA speakers were designed to be so easy to assemble, that you can even put an array together alone if you need to. Operators are aided in their task with the unique self-contained SOLO Rigging System that allows you to quickly assemble and disassemble a complete rig without the need for any special tools or hardware.

Numerous Sound Control Features

The KLA12s offer you a number of other features that make them so exceptionally friendly to use. The Ar-Q Arcuate Equalization processor onboard lets you perform line array tuning that compensates various dimensions of the tonal curve depending on the number of boxes in the array.

Select the DEEP mode (Digital Extension and Excursion Processing), and QSC's DSP algorithm provides noticeably extended bass response, while actively protecting your speakers from damaging low-frequency transients. You can also select a Flat mode, or set your KLA12s to run with external subwoofers.

QSC's proprietary Intrinsic Correction runs in the background -- performing active adjustments to time, frequency and amplitude response to achieve the flattest possible bandpass target. GuardRail circuitry protection keeps the amplifier safe from any damaging distortion.

Super-Versatile I/O Options

When you start to daisy-chain multiple KLA Series loudspeakers together, you'll use the single remote pot wired to the on-board Phoenix-style connector on the rear panel. Additional I/O includes a balanced, line-level XLR input in parallel with an XLR Thru connector, PowerCon In and Thru connectors, and Attenuation Control. Easily visible LED indicators let you monitor Signal, Limit, Power and Standby status.

Features:

- 2 x 500 W power module
- Rugged, ABS enclosure
- SOLO Rigging System
- Ar-Q Frequency Optimization
- 10:1 design supports total array weight up to 480 pounds
- High power 12-inch low frequency driver

Product Description

The QSC KLA12 is a SOLO Rigging System Housed in a rugged ABS enclosure that results in both light weight and long-term durability, the KLA12 features a 12-inch low frequency transducer coupled with a 1.75-inch compression driver. Designed to be used exclusively as a fixed arcuate line array, each KLA12 is set at a 90* horizontal by 18* vertical splay angle, allowing 90* vertical coverage arrays to be configured using only five boxes (most other solutions require six).

KLA's unique self-contained SOLO(tm) (Single-Operator Logistics) Rigging System enables users to quickly assemble (and disassemble) the line array in a fraction of the time without the need for special tools or external hardware.

The KLA12 Ar-Q(tm) (Arcuate Equalization) processing enables users to quickly tune the array, making appropriate frequency compensation adjustments based on the number of boxes. With the click of a dial, the user can select the total number of boxes deployed in the array resulting in an evenly balanced and accurate tonal curve. QSC's proprietary Intrinsic Correction(tm), first introduced with the WideLine(tm) Series, actively adjusts time, frequency and amplitude response to achieve a maximally flat bandpass target.

KLA Series

The 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 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.

KLA Power Module

The KLA Series is comprised of two models, the KLA12 12-inch, 2-way loudspeaker and the KLA181 18-inch subwoofer. The KLA12 features a highly efficient 500 watt by 500 watt power amp. KLA12 Power Module module and the KLA181 offers the same highly efficient power amp module in a 1,000 watt configuration. 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.

KLA loudspeakers incorporate QSC's DEEP(tm) DSP algorithm - providing extended bass response by actively managing potentially damaging low-frequency transients - and GuardRail(tm) 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(tm) In and Thru connectors, Attenuation Control and LED indicators for Signal, Limit, Power and Standby status.

Customer Reviews
5 out of 5 (3 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Simply Amazing and No Fuss Setup"
Sound: These sound amazing in an array of two or three units per side. They match up perfectly with the KW181's when you don't need to fly subs. Feature: The built in DSP for setting up the array size is very simple, qsc has the kla12 file setup and ready for download on the website so you can model the sound for an event beforehand. Powercon connectors make setup safe and secure. Ease of Use: You can setup anything from a 1 to 5 cabinet array in seconds. Can fly this setup with just 1 or 2 people. DSP & Gain controls are so simple someone that has never setup the system before can do it. Quality: Great build quality, solid construction. Best stacking/flying hardware I have seen. Value: They are a bit expensive but for what you get well worth the price. The Wow Factor: The look alone of a 3 speaker array will wow the audience before they even hear the amazing sound Overall: Best purchase I have made by far when it comes to powered speakers. Blows away my JBL's
Style of Music: Everything from latest dub step to jazz

zZounds has verified that this customer bought this product from us. "qsc kla 12"
Overall: We purchased one of the cabinets to review if we want to purchase a full system. We also wanted to determine if they perform well with our kw 152s and k 12s.We are fully aware that in order to fully test them we will need at least three. We used the cabinet at a relay for life event. The event took place at a football field I had 152s pointed one direction, k12s pointed the other and the single kla pointed at the direction that had the longest distance to the outside of the field. My initial response is wider deeper and longer we only lost 7dbs of volume in 200 feet the sound was very clear and the cabinet worked well with the other k series speakers. based on that we will continue to purchase more as budget allows
