The KLA12 loudspeakers, when attached together, are a fixed-arcuate line array with splay angles of 18° matching the individual loudspeaker's vertical dispersion angle of 18°. The KLA12 features QSC's SOLO™, allowing you to attach KLA12s together with one person, and no tools.

Attaching a KLA12 to a KLA12 or KLA AF12 Array Frame The KLA12 loudspeakers come with the attaching hooks in the retracted position, indicated by the slide down, and the lever "B" in the down, or locked position as shown in Figure 1.

Attaching a KLA12 to a KLA181 The KLA12 cannot be attached to the top of a KLA181. There are various ways to facilitate attaching a KLA12 to a KLA181, and they vary depending on the specific circumstances. Be sure to use proper rigging techniques, and/or employ a professional engineer.

Separating a KLA12 from a KLA AF12 Array Frame, KLA12, or KLA181 Figure Refer to 1. Safely support the bottom KLA12 in the array. You must support both sides of the loudspeaker, and relieve the weight of the loudspeaker from its latching mechanism in order to separate one loudspeaker from another.
Page 13
Attaching a KLA181 to a KLA AF12 Array Frame Refer to Figure 18 ROTE!: The KLA AF12 Array Frame must be oriented with the KLA181 feet pointing down as shown in Figure 18. For more detail, refer to Figure 3 on page 8. 1.

Suspending the KLA Array AARNRNG!: Review the topic "Rules for Suspension" on page 4. The maximum number of KLA 12 Loudspeakers in any array, with or without KLA 181 Loudspeakers, is five. Suspended Loudspeakers per Array Array Configuration Option Maximum Number of KLA181 Loudspeakers Maximum Number of KLA12 Loudspeakers —...

Attach the Rigging Cables to the KLA AF12 Array Frame You can achieve different tilt angles by attaching the suspension cabling to one of the 12 holes in the Extension Bar. The front-to-back orientation of the Extension Bar determines if the array is tilted up or down. As the suspension cabling is moved towards the Extended Portion of the Extension Bar (Figure 21), the tilt angle is increased.
1. Adjust the QSC Tilt-Direct™ dual angle pole socket to the zero (default) position or the 9° position. 2. Carefully place one KLA12 on the loudspeaker pole by inserting the pole completely into the QSC Tilt-Direct™ pole socket. Use proper lifting techniques.

AARNRNG!: Do not connect more than five KLA Series loudspeakers together using the loop-thru power cables (four loop- thru cables, one AC power cord). If you are using loop-thru power cables, make all loop-thru connections prior to connecting to the AC mains. 3.
These functions include crossovers, time alignment, limiting and protection, thermal management some of which are implemented using a number of proprietary features. QSC has designed exclusive DSP functions that greatly enhance the capabilities and...
Intrinsic Correction™ – Introduced on QSC Concert/Touring products, Intrinsic Correction is a proprietary process and set of signal processing algorithms that address correctable intrinsic characteristics of transducers, waveguides and enclosures. The net result is that any KLA12 system will present extraordinarily even and consistent energy throughout the physical listening area of the loudspeaker, resulting in a very musical, acoustically transparent system.
Additional Features Front LED Switch The blue power LED, on the front of the loudspeakers, may be set to any of three modes by the FRONT LED switch (Figure 33) located on the amplifier panel. PWR – This is the factory setting which means the LED illuminates when the POWER switch is in the ON position and the unit is not in STANDBY.
