K-array Redline KL18 User manual

K-array is the new voice that sings
aloud, "outside the choir", and whose
performance is better than any other
products. Born on-the-road, in the PA
world, where you get no discount, you
have to give your best as fast as you
can, often with a "compressed" budget,
K-Array systems have been designed to
give precise answers to precise needs.
Driven by new generation digital
engines, with power/dimension/weight
ratios that are ten times better than any
other professional products, K-arrays
can deliver the full spectrum of musical
styles with clarity, power, punch,
intelligibility and evenness across both
volume levels and the frequency
spectrum. These systems can be
remotely controlled and come with a
sophisticated on-board software,
allowing the user to shape their
performance to taste and needs. Inside
K-array systems you will find something
that only we can offer: the best in
t e c h n o l o g y, p r o u d l y c o n c e i v e d ,
designed and produced in Italy. If they
were cars, they would be Ferrari. Don't
agree to pay for a simple brand, claim
performance, and don't believe those
who maintain that these products are
only for few people, the only truth is that
K-array systems are unique, but
affordable and within everybody's
reach!

1. SAFETY INSTRUCTIONS
!
This symbol, wherever it appears, alerts you to
important operating and maintenance istructions in
the accompanying literature. Read the manual!
Dangerous voltages: risck of electric shock.
For information about the disposal of Waste Electrical
and Electronic Equipment (WEEE), please refer to the
website at

This symbol alerts the user to the presence of
re c om m en d at i on s a bo u t pr o du c t' s u se a n d
maintenance.
CAUTION !
!
• To reduce the risk of electric shock, disconnect the amplifier from the AC mains before installing audio cable.
Reconnect the power cord only after making all signal connections.
• Connect the amplifier to a two-pole, three wire grounding mains receptacle. The receptacle must be connected to
a fuse or circuit breaker. Connection to any other type of receptacle poses a shock hazard and may violate local
electrical codes.
• Do not install the amplifier in wet or humid locations without using weather protection.
• Do not allow water or any foreign object to get inside the amplifier. Do not put objects containing liquid on, or near,
the unit.
• To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight. Do not install the unit near heat
emitting appliances, such as a room heater or stove.
• No naked flame sources such like lighted candles should be placed on the device.
• The amplifier should be placed so that its location does not interfere with its proper ventilation. For example, the
appliance should not be situated on a bed, carpet, or similar surface that may create an obstacle for the ventilation
openings.

2. INTRODUCTION
3. VOLTAGE REQUIREMENTS
KA 10 operates safely and without audio discontinuity if the AC voltage stays within either of two operating
windows: 95-125 (voltage selector on 115 V) or 195-250 V (voltage selector on 230 V), at 50 or 60 Hz.
115-230
Connecting a 115V system on a 230V AC Power causes heavy
damages to the device and serious risk for users .
CAUTION
!
The device is default set to be connected to 230 V AC Power. To use the device on a 115 V AC Power you need,
before connecting it, to move the voltage selector's cover, just loosening the two screws, and to choose the correct
use voltage by the red switch. Be sure that both voltage set on the selector and AC Power have the same value .
Always close the voltage selector's cover before connecting the device to AC Power. Change the label that points
out the correct voltage in use.

The KF12 is a self-powered 2 way fullrange coaxial speaker. In its ultra-compact sizes it has an incredible reserve of power
that ensures very high pressure on a wide 3D coverage, maintaining the sound quality constant. The KF12 is ideal for medium
throw applications, like theaters, concert halls, churches. The KF12 is designed to easily integrate with KL18 ultralight
subwoofer, using the Sub power Out on the KF12.
The KF12 uses one 12" inches cone drivers for low-mid frequencies with 3" voice coil, powered by one power amplifier
channels. The mid-high frequencies section uses one 3" voice coil compression drivers. The coaxial mounting system,
ensure a coherent frequency response on all the 70° x 70° front area.
The transducers of KF12 are driven by an internal DSP module, a dedicated remote control software allows to control the
speaker from PC.
All the KF12 components are designed by K-array R&D department and custom made under K-array control quality system.

Notes for data
1. Power handling is measured following AES standard conditions: transducers driven continuously for two hours with a band-limited noise signal having 6 dB of crest factor.
2. Max power is the maximum RMS applicable power for a musical signal, the referement signal is the one proposed by EIAJ standard.
3. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
4. Free field measured with 1/3 octave frequency resolution at 2 mt.
5. Measured@4 mt then scaled@1 mt.
6. Measured with audio source @1 mt.
7. This is the frequency in which the transducers produce the same sound pressure level (measured@2 mt).
8. Amplifier wattage rating is based on the maximum unclipped burst sine wave RMS voltage that the amplifier will produce into the nominal load impedance .
