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.
