Application 0˚ — Figure 7 — -9˚ — Figure 8 — — Figure 9 — The KLA Series can be configured in an array with combinations of loudspeakers, refer to "KLA Maximum Suspended Load" on page 4. Using SOLO™ (Single-Operator Logistics), box‑to‑box attachment of the KLA12 is simple, self-contained, and requires no tools or additional hardware. The KLA181 requires an 6 mm hex key (supplied) for box-to-box and KLA AF12 deployment, and a 6 mm hex key for M10 suspension.
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 (1) down, and the lever "B" in the down, or locked position as shown in Figure 8. 1. Move the lever button (Figure 8, 2) upwards, and then rotate lever "B" up, as shown, until it stops. 1 1 2 2. Make sure that levers labeled "B" and slides (1) on both sides of the bottom loudspeaker are in the positions shown in Figure 9.
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. Following is one example. Suspend the KLA181 as described in "Suspending the KLA Array" on page 14, then carefully attach a KLA12 to the bottom of the KLA181 using the KLA12 attaching mechanism.
Separating a KLA12 from a KLA AF12 Array Frame, KLA12, or KLA181 Refer to Figure 15. 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. 2 1 2. Move the lever button (1) upward, and then rotate lever "B" up, as shown, until it stops. 3. Push the slide (2) downward to rotate the hook (not shown) to the retracted position.
Attaching a KLA181 to a KLA AF12 Array Frame Refer to Figure 18 NOTE: 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. 2 1. Place the KLA181 on the floor, or other suitable surface, and make sure the hooks are retracted. If not, insert the supplied 6 mm hex key into the hex socket (Figure 17, 4 on page 12) and rotate the key fully to the Unlocked Position as noted next to the hex socket on the loudspeaker. 2.
Suspending the KLA Array WARNING!: 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.

(25 kg) 104 lbs. (47.2 kg) 23 lbs. (10.
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.
WARNING!: Do not mount more than two (2) KLA12 loudspeakers on a pole over the KLA181 subwoofer, KW181 subwoofer or on a loudspeaker tripod. Do not use a pole longer than 36 inches (914 mm) when supporting one or two KLA12s over a KLA181 or KW181 subwoofer. 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.
Balanced Inputs: Connect to the plug as shown. Unbalanced Inputs: Connect to the plug as shown. 1 = shield (ground) 3 = jumper to pin 1 2 = plus (+) 1 = shield (ground) 3 = minus (-) 2 = plus (+) — Figure 31 — — Figure 30 — Output Both the KLA12 and KLA181 have discrete, direct LINE OUT male XLR connectors (Figure 26, 4), wired in parallel with the LINE IN. The signal on the LINE OUT is exactly equivalent to the signal on the LINE IN.
WARNING!: Do not connect more than five KLA Series loudspeakers together using the loop-thru power cables (four loopthru 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. Insert the grey powerCON® connector, on the loop‑thru cable, fully into the grey AC OUT connector (3) on the amplifier. 4. Twist the powerCON® connector clockwise until it locks in place. 5.
Rear LED Indicators Blue POWER LED 3 Refer to Figure 31, 1 2 • Illuminates when the AC power switch is in the ON position, the amplifier is not in standby, the AC mains power cord is properly connected, and the AC mains are functioning properly • Extinguishes when the AC Power switch is not in the ON position, or off, AC mains power is not available to the loudspeaker, or the amplifier enters STANDBY.
Proprietary DSP Functions Excursion Limiting – The KLA Series system utilizes a proprietary limiter that prevents woofer over-excursion. Over-excursion occurs when a voltage presented to the woofer causes the cone to physically travel too far. This builds up excessive heat, stresses the moving parts of the woofer, produces audible artifacts and distortion and reduces the woofer’s lifespan.
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. OFF – The front LED does not illuminate in the OFF position. This setting is recommended in applications where the light from the front LED may be visually objectionable.
