INTRODCTION

Designed to be consistently unique like all the unique K-array products, the KX12 is a radical reinterpretation of a traditional coaxial 12” speaker. Its compact shape and different accessories allow the KX12 to perform as a powerful audio point source or as part of a line array.
When high pressure is needed in the foreground with a rapid depreciation once distanced from the source, the KX12 can meet this demand to become one of the most useful tools for an installer. Similar to the Firenze KH7, an asymmetric 100° by 30° horn with an adjustable orientation gives to the speaker an added value providing two modes of coverage to choose from to meet the needs of different installations.
Additionally, dedicated accessories assist in the set up of joining, flying and stacking the speaker, making it a perfect line array component.
Its steel chassis offers maximum rigidity in a minimum size. The speaker delivers a continuous SPL of 127 dB and has a frequency range of 120 Hz to 19 kHz and it is compatible with all K-array KMT subwoofers.

SAFE TY INFORMATION

Warning: failure to follow these safety instructions could result in injury or damage to the device or other property.

MPORTANT SAFETY INSTRUCTIONS

• Read these instructions.
• Keep this instructions.
• Heed all warnings.
• Follow all instructions and keep all warnings.
• Only use attachments/accessories specified by the manufacturer
• Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus.
• When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tipover.
• Avoiding hearing damage. Professional loudspeakers are capable of producing extremely high sound levels and should be used carefully. Never stand close to loudspeakers driven at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that over time may sound normal but can be damaging to your hearing. Hearing loss worsens after exposure to a sound level of 90 dB or over for an extended period of time. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected.
• Choking Hazards. This device contains small parts, which may present a choking hazard to small children. Keep the device and its accessories away from small children.
• Do not make repairs yourself. Never attempt to disassemble, repair or modify the system yourself. Disassembling the unit may cause damage that is not covered under the warranty. The device contains no user-serviceable parts. Repairs should only be performed by factory trained service personnel.
• Sound distortion. Do not operate speakers for an extended period of time with sound distortion. This is an indication of malfunction, which in turn can generate heat and result in a fire.
• Carrying, handling and installing the device. The device contains sensitive components. Do not drop, disassemble, open, crush, bend, deform, puncture, shred, incinerate, paint, or insert foreign objects into it. If your device has been dropped or damaged, unplug the power cable immediately.
• Setup. Set up your device on a stable, horizontal surface. If combined or mechanically connected with other products, always verify the stability of the resulting system. Install the unit only in a location that can structurally support the weight of the unit and far away from interference with the stability of the system. Ensure the wind does not interfere with the system’s stability, taking extra securities such as chains, weights, ropes or any other certified anchoring systems. Otherwise a unit could fall, causing property damage, personal injury or even death. The system should only be suspended by qualified personnel following safe rigging practices. Securing fixtures to the building structure are vital. To clarify any doubts you may have, seek help from architects, structural engineers or other specialists.

UNPACKING

Each K-array speaker is built to the highest standard and thoroughly inspected before leaving the factory. Upon arrival, carefully inspect the shipping carton, then examine and test your new amplifier. If you find any damage, immediately notify the shipping company. Only the consignee may institute a claim procedure regarding the system’s electronic equipment.

PRODUCT OVERVIEW

WIRING

KX12’s internal wiring is designed to pick up the audio power signal from pins 1+ / 1- of a Speakon NL4 connector. Pins 1+ and 1-, such as pins 2+ and 2-, are directly wired from one socket to the other, so that the two sockets are equivalent and can connect the speaker to the amplifier or to another KX12 driven in parallel by the same amplifier channel.

NOTE:
The K-array KA84 amplifier can drive up to two KX12 units per channel

HORN ORIENTATION

The KX12 features a 12” woofer and a compression driver coupled to an asymmetric horn. Because the horn is asymmetric, its sound dispersion pattern is different in respect to its axes: the sound dispersion is wide along the axis labeled FLOOD and narrow along the axis labeled SPOT. The horn can be manually rotated 90° using the two handles situated at the front.

In this position the sound dispersion pattern is wide (FLOOD – 100°) in the horizontal plane and narrow (SPOT – 30°) in the vertical plane.| In this position the sound dispersion pattern is narrow (SPOT – 30°) in the horizontal plane and wide (FLOOD – 100°) in the vertical plane.

TIP
If you connect more units together to form a vertical array, make sure to orient all horns in vertical (above picture on the left) so that they are aligned in the same direction of the array. This will assure a wide horizontal coverage with a narrow vertical dispersion.

RIGGING

K-array offers a variety of dedicated accessories to mount and connect the KX12 speakers for a wide range of applications.
This section highlights the main accessories available for this product.

9.1 SUSPENDING THE KX12 WITHAFLY BAR
KX12 units can be suspended using the K-FLY2B, a fly bar; K-FLY22, hardware used to connect the first unit to the fly bar; and K-JOINT2B, the hardware that connects a KX12 to the K-FLY22 or to another KX12.

1. First connect the two parts of a K-JOINT2B to each speaker with the provided 5×16 screws.

2. Join the K-FLY2B and the K-FLY22 with the two 8×40 piston pins provided with the system.

3. Connect the first KX12 unit to the fly bar. Secure with the two 8×40 piston pins provided with the system.

4. Insert two joint blocks and secure each of them with the two 5×30 piston pins provided with the system. The orientation of the joint blocks and the holes used will affect the angle between the fly bar and the KX12, as shown below. We recommend setting an angle of 0° between the fly bar and the first KX12 unit.

If you want to angle the speaker by 0°, +5°, +10° or +15°, position the joint block so that the letter “A” is at the bottom. Plug a piston pin in the hole labeled “A”, adjust the angle of the speaker and plug the second piston pin in the hole corresponding to the desired angle.
If you would like to angle the speaker by -5°, -2.5°, +2.5° or +7.5°, position the joint block so that the letter “B” is at the bottom. Plug a piston pin in the hole labeled “B”, adjust the angle of the speaker and plug the second piston pin in the hole corresponding to the desired angle..

5. Position the next unit. Connect the two units with two 8×40 piston pins. Insert the two joints and regulate the angles as explained on the previous page. Secure with four 5×30 piston pins.

6. Repeat Step 5 to connect the other units (up to 6 per line array).

Warning: up to 6 (six) units per cluster can be connected in line array. Do not exceed the array maximum lenght of 6 units.

9.2 WALL-MOUNTING THE KX12
The K-WALL2 accessory is used to mount a KX12 unit to a wall.
9.3 STANDING THE KX12 ON A KMT SUBWOOFER
KX12 units can be mounted on a KMT subwoofer using the K-FOOT2B-202 and the K-JOINT2B accessories. Excellent examples of this combination are the K-array portable stereo systems KRX202, KRX402 and KRX802.

The next step-by-step instructions demonstrate how to mount a KRX802. The mounting procedure for the other systems is not dissimilar.
Below are the accessories needed to mount the system:

1. Screw the pole into the subwoofer.

2. Insert the K-FLY22 adapter and screw the knob.

3. Connect a K-JOINT2B to each KX12 unit.

4. Insert the first KX12 unit. Secure with the two 8×40 piston pins provided with the system.

5. Insert two joint blocks and secure each of them with the two 5×30 piston pins provided with the system. The orientation of the joint blocks and the holes used will affect the angle between the K-FLY22 and the KX12, as shown in the next page.

6. Repeat Steps 4 and 5 to add the other units (up to 3 per cluster).

If you want the to angle the speaker by 0°, +5°, +10° or +15°, position the joint block so that the letter “A” is at the bottom. Plug a piston pin in the hole labeled “A”, adjust the angle of the speaker and plug the second piston pin in the hole corresponding to the desired angle.
If you want the to angle the speaker by -5°, -2.5°, +2.5° or +7.5°, position the joint block so that the letter “B” is at the bottom. Plug a piston pin in the hole labeled “B”, adjust the angle of the speaker and plug the second piston pin in the hole corresponding to the desired angle.
