Suspending the KLA Series Loudspeakers

WARNING!:

Read and follow these instructions carefully. If the loudspeakers are not suspended properly, they could fall,

causing personal injury and damage to the equipment.

Rules for Suspension

• Consult a professional mechanical or structural engineer, licensed in the jurisdiction of the sound system installation, to review, verify, and approve

all attachments to the building or structure.

• Employ the services of a certiﬁ ed, professional rigger for hoisting, positioning, and attaching the equipment to the supporting structure.

• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.

• Always calculate suspended loads before lifting to make sure suspension components and hardware are used within their respective load limits.

• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which you will suspend

the equipment.

• Use only the KLA AF12 Array Frame or the M10 installation points for suspending the array.

• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can have hidden

structural weakness.

• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the loads.

• Before lifting, always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for cracks, wear,

deformation, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly. Discard any worn, defective, or suspect

parts and replace them with new appropriately load-rated parts.

Shock Loading

When a load is either moved or stopped, its static weight is magniﬁ ed. Sudden movements can magnify the static weight several times. This

magniﬁ cation of static weight is called "shock loading". Shock loading poses a danger to equipment and workers. The effects of shock loading can be

instantaneous, or may remain undetected unless the equipment is visually damaged. Proper preparation for shock loading requires careful planning

and knowledge of equipment, suspension, and lifting practices.

Shock loading of equipment and structures is usually conﬁ ned to lifting and installation, but natural forces (winds, earthquakes, and so on) can impose

shock loads several times the static load. Because of this, structures and suspension equipment must be capable of supporting several times the

weight of the suspended equipment.

KLA Maximum Suspended Load

The KLA components are engineered for a 10:1 design factor.

Use the KLA AF12 Array Frame or the M10 Integrated Suspension points to suspend one KLA Array consisting of one of the following three array

conﬁ guration options. The maximum number of KLA12 Loudspeakers in any array, with or without KLA181 Loudspeakers, is ﬁ ve.

Introduction

The KLA Series brings the power and sophistication of a line-array system into an easy-to-use product signiﬁ cantly redeﬁ ning the line-array-product

category. With its simple Lift, Click and Play approach, KLA deploys in a fraction of the time required by comparable line-array products. This ﬁ xed

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.

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

efﬁ cient 500 W x 500 W power-amp module in a rugged, lightweight ABS enclosure that can be used in multiple conﬁ gurations using QSC's unique

SOLO™ (Single-Operator Logistics) Rigging System and/or Tilt-Direct™ 35 mm pole socket. The KLA181 offers the same highly efﬁ cient power-amp

module in a 1,000 W conﬁ guration in a birch plywood enclosure. KLA Series loudspeaker models incorporate:

QSC’s DEEP™ DSP algorithm, providing extended bass response by actively managing potentially damaging low-frequency transients,

GuardRail™ circuitry protection that prevents the ampliﬁ er module from unnatural and destructive clipping,

Intrinsic Correction™ (KLA12) to correct for inherent characteristics of the loudspeakers, waveguide, and enclosures,

Ar-Q™ to make equalization adjustments based on the number of KLA12s in the array,

Auto Standby mode that automatically engages after ﬁ ve minutes of inactivity, but upon resumption of audio signal, the power module on the KLA

awakens instantly for immediate output.

Remote Gain control capability in an installed application using a single potentiometer wired to a Euro-style connector.

Balanced, line-level XLR input, in parallel with an XLR output, for distributing the audio signal to multiple loudspeakers.

powerCON® AC In and AC Out connectors for powering up to ﬁ ve loudspeakers on a single 15 amp/120 V (8 amp/240 V) electrical circuit.

Other features include LED indicators for Signal and Limit, and discrete LED indicators for Power/Standby status.
