1. INTRODUCTION
2. KEY FEATURES
3. APPLICATIONS
The K-array KY102 is a passive speaker system comprised of eight 4” neodymium magnet transducers
housed in an elegant and sturdy stainless steel frame. The vertical dispersion pattern can be switched
for wide or narrow coverage, allowing for a great variety of applications. The eight closely-spaced
cone drivers boast true line array characteristics, such as phase coherence, low distortion and focused
listening in both the near field and at a distance from the speaker.
A variety of rigging accessories allows for many linking and hanging options for the KY102 in vertical
and horizontal line array configurations to satisfy many different venue requirements during temporary
events as well as permanent installations.
For easier use and integration with other speakers or amplifiers, the KY102 is equipped with two different
values of impedance (8Ω– 32Ω). The KY102 is able to reproduce the whole vocal frequency range with
high intelligibility. Integrating one of K-array’s powered subwoofers (KMT18, KMT21, KMT218), configured
with specific presets for the KY102, assures excellent coverage of the entire musical frequency range.
All KY102 components are designed by the K-array R&D Department and custom-made under the
K-array Quality Control System.
• Unique performance-to-size ratio
• Vertical, horizontal and 3D line array applications
• Multiple 4” long excursion, full-range cone drivers
• Wide horizontal coverage
• Electronically protected
• Selectable 8 ohm or 32 ohm impedance
• Selectable vertical pattern (spot - flood)
• Weather proof, suitable for outdoor installations - IP54
• Theatre, club, house of worship

4. SAFETY INFORMATION
Warning: failure to follow these safety instructions could result in injury
or damage to the device or other property.
IMPORTANT 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 tip-over.
• 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.
• Set up. Set up your device on a stable retaining horizontal surface. If combined or mechanically
connected with other products, always verify the stability of the resulted system. Install the unit only
in a location that can structurally support the weight of the unit and far away from people who can
interfere with the stability of the system. Assure that the wind does not interfere with the system’s
stability, taking extra securities like chains, weights, ropes or any other certified anchoring systems.
Doing otherwise may result in the unit falling down, causing personal injury or property damage
or even death. The system should only be suspended by qualified personnel following safe rigging
practices. Secure fixings to the building structure are vital. To clarify any doubt you may have, seek
help from architects, structural engineers or other specialists.

5. 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.

7. WIRING
KY102 internal wiring is designed to pick up 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 the
two sockets are equivalent and can be used to connect the speaker to the amplifier or to connect the
speaker to another KY102 driven in parallel by the same amplifier channel.
NOTE:
• The K-array KA84 amplifier can drive up to two KY102 @ 8Ω
per channel or up to four KY102 @ 32Ωin bridge mode.
• The K-array KMT218 and KMT21 powered subwoofers can drive
up to two KY102 @ 8Ω.
7.1 IMPEDANCE SWITCH
KY102 features a switch which allows users to select the impedance of the speaker (8Ω/32Ω).
The value to be selected depends mainly on the amplifier you use to drive the unit. To find the correct
impedance value to be set on the unit, we recommend that you check the Output Configuration Page
on your K-array KA amplifier or KMT active subwoofer you use to drive the unit. Please refer to your
amplifier or KMT’s User Guide for further details.
IMPEDANCE SWITCH COVERAGE SWITCH

KY102 features a switch which allows users to select the vertical coverage of the speaker.
Flood coverage sets a wide vertical diffusion angle of 30°. Flood coverage is suggested for single
speakers in diffused short throw applications to obtain maximum diffusion with a minimum footprint.
Spot coverage sets a narrower vertical diffusion angle of 7° and is recommended for long throw or
monitoring application.
When more units are combined in a line array configuration, make sure to set the coverage to Spot.
SPOT Coverage - 7°
FLOOD Coverage - 30°

8. RIGGING
K-array offers a variety of dedicated accessories to mount and interconnect the KY102 speakers for a
wide range of applications.
In this section we introduce you to the main accessories available for this product. More information can
be found in the accessories’ user guides.
8.1 SUSPENDING FROM THE FLY-BAR
KY102 units can be suspended using the K-FLY2 fly bar accessory and the K-JOINT2 hardware accessory
used to connect together two units or to connect a unit to the fly bar. Please refer to the K-FLY2 User
Guide to check all the available configurations and for safety information and operation details.

8.2 HANGING ON THE WALL
The K-WALL2 accessory is used to mount a KY102 speaker on a wall or a stand.
8.3 STANDING ON THE BASE
The K-BASE2 accessory assists in standing up to 2 units. For proper installation and operation, connect
the units to the base with K-FOOT2 and K-JOINT2 accessories. Where possible, screw the feet of the
K-BASE2 to the ground.

8.4 STANDING ON A KMT SUBWOOFER
Up to two KY102 can be mounted on a KMT subwoofer by using the K-FOOT2 and K-JOINT2 accessories.
Acoustically speaking, two KY102s perfectly match with a KMT218 subwoofer. An excellent example of
the use of this combination is the K-array portable system KR802.

8.5 GROUND LAYING
KY-STAGE allows users to safely lay the speakers on the ground with three different angles: 0°, 30° and
45°. Ideal applications are monitoring and front-fill.
