• Read these instructions.
• Keep this instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with dr y cloth.
• Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.
• Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
• 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 car t/

• Unplug this apparatus during lightning storms or when
unused for long periods of time.
• This loudspeaker system is intended for professional use.
• Beware of sound levels. Do not stay within close proximity of
loudspeakers in operation. Loudspeaker systems are capable
of producing very high sound pressure levels (SPL) which can
instantaneously lead to permanent hearing damage. Hearing damage
can also occur at moderate level with prolonged exposure to sound.
Check the applicable laws and regulations relating to maximum sound
levels and exposure times.
• Before connecting the loudspeakers to other devices, turn off the power
for all devices.
• Before turning the power on or off for all devices, set all volume levels to
minimum.
• Use only speaker cables for connecting speakers to the speaker
terminals.
• Be sure to observe the amplifier’s rated load impedance particularly
when connecting speakers in parallel. Connecting an impedance load
outside the amplifier’s rated range can damage the devices.
• Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
• K-array will not shoulder any responsibilities for products modified
without prior authorization.
• K-array cannot be held responsible for damage caused by improper use

Vyper
User Guide
Thank you for choosing this K-array product!
To ensure proper operation, please carefully read this
reference manual and safety instruction before using the
product. After reading this manual, be sure to keep it for
future reference.
Should you have any questions about your new
device please contact K-array customer service at
support@k-array.com or contact the official K-array distributor
in your country.
The Vyper line is the flatest speaker in the K-array portfolio.
The passive speaker system is housed in an elegant and
resistant aluminum frame turned on a lathe from a solid
metal block.
With closely-spaced cone drivers, the Vyper line –
comprised of the half-meter-long KV52 and the 25cm-long
KV25 – demonstrates true line array characteristics: phase
coherence, low distortion and focused listening in both the
near field and at a distance from the speaker. This Pure Array
Technology allows the Vyper to cover venues uniformly and
provide long throw.
For easier use and integration with other speakers or
amplifiers, the Vypers feature selectable impedance and
when paired with a subwoofer from the Rumble or Truffle
line and powered by a Kommander amplifier with specific
presets optimized for the Vyper, the loudspeaker assures
excellent coverage of the entire musical frequency range.
