1. INTRODUCTION
2. KEY FEATURES
The K-array KP52-54 I and KP102-54 I are specifically designed to be included in voice alarm systems.
The K-array Pythons are passive speaker systems, comprised of 3.15” neodymium magnet transducers
housed in an elegant and sturdy stainless steel chassis. Available in two lengths, the KP52-54 I features
6 drivers in a 0.5 m (20”) chassis, while the KP102-54 I features 12 drivers in a 1 m (40”) chassis.
The Pythons’s closely spaced cone drivers provide phase coherence, low distortion and focused listening
both up close and at a distance.
To accommodate a range of applications, the vertical dispersion pattern can be switched for either wide
or narrow coverage.
For integration with other speakers or amplifiers, the KP52-54 I and KP102-54 I offer selectable
impedance (8Ω/32Ωfor the KP52-54 I and 4Ω/16Ωfor the KP102-54 I).
Pythons are able to reproduce the entire vocal frequency range with excellent intelligibility, starting from
100 Hz.
Integrating powered K-array subwoofers (KMT12, KMT18, KMT21, KMT218) ensures excellent coverage of
the entire musical frequency range. K-array’s KA amplifier series also features custom presets, optimized
for use with the Python series.
All Python components are designed by K-array and custom-made under K-array’s quality control system.
• EN54-24 compliant
• Unique performance-to-size ratio
• Vertical and Horizontal applications
• Multiple 3.15” long-excursion full-range cone drivers

3. 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.

4. 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.

6. WIRING
KP52-54 I and KP102-54 I feature a 2x2.5 cable coming out from the chassis, ready to be connected to
the cable coming from the amplifier.
6.1 IMPEDANCE SWITCH
KP52-54 I and KP102-54 I feature a switch which allows users to select the impedance of the speaker
(KP52-54 I: 8/32 Ω, KP102-54 I: 4/16 Ω).
The value to be selected depends mainly on the amplifier you use to drive the unit. Impedance must
be set to high (32 Ωfor KP52-54 I and 16 Ωfor KP102-54 I) when speakers are driven by KMT active
modules or by the KA84 amplifier. Low impedance may be used when speakers are driven by a KA24
amplifier.
Please refer to your amplifier’s specifications to select the correct speaker impedance for your
configuration.

KP52-54 I and KP102-54 I feature a switch which allows users to select the vertical coverage of the
speaker.
Flood coverage sets a wide vertical diffusion. 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 and is recommended for long throw or monitoring
application.
