1. INTRODUCTION
The KV52 Vyper is an ultra-flat passive speaker system comprised of eight 1” neodymium magnet
transducers housed in an sleek, durable aluminum chassis. The eight closely-spaced, full-range cone
drivers provide true line array characteristics: phase coherence, low distortion and focused listening in
both the foreground and at a distance from the speaker.
Two included steel brackets provides an easy-to-mount option for permanent wall installations. For
easier use and integration with other speakers or amplifiers, KV52 allows the user to select between
two different values of impedance: 16Ω and 64Ω. At 64Ω, as many as sixteen KV52 speakers can be
powered by a single amplifier channel at 4Ω, which eliminates the need of 70 V amplifiers for wider
distributed installed systems.
The KV52 is able to reproduce the entire vocal frequency range with high intelligibility, starting from 150
Hz. Integrating an ultra-compact K-array subwoofer powered by KA amplifier set with specific presets
optimized for the KV52 assures excellent coverage of the entire musical frequency range.
All KV52 Vyper components are designed by the K-array R&D Department and custom made under the
K-array quality control system.

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 these 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 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 by 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 or paint the device nor
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, using 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, 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 audio element. If
you find any damage, immediately notify the shipping company. Only the consignee may institute a
claim procedure regarding the system’s electronic equipment.

8. WIRING
The KV52 features two 2-pin phoenix connectors wired in parallel. The two connectors are interchangeable
and can be used to connect the speaker to the amplifier or to connect the speaker to another KV52
driven in parallel by the same amplifier channel.
The KV52 allows the user to select two different values of impedance (16Ω – 64Ω) with a switch situated
on the rear panel. At 64Ω as many as 16 KV52 speakers can be powered off a single KA84 amplifier
channel.

9. INSTALLATION
9.1 INCLUDED WALL BRACKETS
The KV52 can be easily installed on the wall using the two included wall brackets. Secure the two
brackets on the wall using four M4 screws. Position the KV52 between the two brackets and use the
four included M3 hex screws to secure the chassis to the brackets.

KV52 Ver 1.2
9.2 MOUNTING THE UNIT TO THE WALL
The KV52 can be installed on the wall just using two M4 screws (not included). The grill must be
removed to insert the screws (T10 torx screw driver required).

KV52 Ver 1.2
9.4 JOINING TWO UNITS
The two included linking brackets allow the user to join two units together to create a longer array. The
bottom unit is tilted 5° downwards to properly cover the audience closest to the array. Use the four
included hex screws to join the two speakers.
