1. INTRODUCTION
Vyper K V50 is an ultra-flat passive speaker system comprised of eight 1” neodymium magnet transducers
housed in an elegant and sturdy aluminum chassis. The eight closely spaced cone drivers provide tr ue
line array characteristics - phase coherence, low distortion and focused listening in both the near field and
at a distance from the speaker. A steel bracket accessory provides an ease to mount wall application for
permanent installations. For easier use and integration with other speakers or amplifiers, KV50 allows the
user to select two dif ferent values of impedance (16Ω – 6 4Ω). At 64Ω as many as 16 K V50 speakers can
be powered off a single amplifier channel at 4Ω, which eliminates the need of 70 V amplif iers for wider
distributed installed systems. The KV50 is able to reproduce the whole vocal frequency range with high
inte lligibilit y, starting from 150 Hz. Integ rating one of the K-array subwoof ers (KU3 6, KMT12P), powered by a
KA10-10 amplifier set with specific presets optimized for the KV50 assures exc ellent coverage of the entire
musical frequency range.
All Vyper KV50 components are designed by the K-ar ray R&D department and custom-made under the
K-array quality control system.

6. SAFETY
WARNING
• Only install the speaker in a location that can
structurally support the weight of the unit. Doing
otherwise may result in the unit falling down and
causing personal injury and property damage.
• Professional loudspeakers are capable of
producing extremely high sound levels and should
be used with care. Hearing loss is cumulative and
can result from extended exposure to levels in
excess of 90dB.
• Do not operate the speaker for an extended period
of time with the sound distorting.This is an indication
of malfunction, which can cause heat build-up and
result in a re.
• Never stand close to loudspeakers driven at high level.
• Suspending the system should only be done by
qualied personnel, following safe rigging practices.
Secure xings to the building structure are vital.
If there is any doubt, seek professional help from
architects, structural engineers or other specialists.
• No open ame sources, such as lighted candles,
should be placed near the device.
• Do not attempt to disassemble the unit. The unit
contains no user serviceable parts. Repairs should
be performed only by factory trained service
personnel.
