1. INTRODUCTION
The KF12MT and the KF12P are K-array’s newest multi-task additions to its portfolio of professional, high-quality loudspeakers in the
Redline Series. The KF12MT is a 12” coaxial full range multi-purpose powered speaker and is the successor to the long serving KF12
model.
Compared to its predecessor, this portable speaker features exciting updates. The KF12MT’s integrated on-board touch screen with
matrix control provides intuitive managing and editing of powerful DSP controlling. Additional functionalities include: a delay up to
400ms, parametric filters for room eq, 2 analog + 2 digital inputs in AES/EBU, routing options, USB and Serial connections for remote
control and a full range powered output of 1000 W on 8 Ω. Having 2 analog or digital fully independent inputs on board can create real
stereo systems using one powered and one passive KF12P speaker. Thanks to its multi-purpose function, it can satisfy many different
venue requirements. It is ideally used as a stage monitor due to its wedge shape, as a stereo system with one active (KF12MT) and one
passive (KF12P), or as a main PA system for small and medium size events and more.
Designed and manufactured in Italy, the KF12MT and the KF12P give uncompromising sound quality in a small footprint and are
compatible with a variety of accessories. Housed in a black wood chassis and black steel grill, the KF12MT has a modern, sophisticated
look. Customized colors are available upon request.

4. UNPACKING
Each K-array loudspeaker is built to the highest standard and thoroughly inspected before leaving the factory. Upon arrival, carefully in-
spect the shipping carton, then examine and test your new loudspeaker. If you find any damage, immediately notify the shipping company.
Only the consignee may institute a claim procedure regarding the system’s electronic equipment.
5. SAFETY
WARNING
Read all safety information below and operating instructions before using this device to avoid injury.
Warning. Failure to follow these safety instructions could result in fire, shock or
other injury or damage to the device or other property.
SAFETY AND HANDLING INFORMATION
It is important that loudspeaker systems are used in a safe manner.
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. Over time you can adapt to a higher volume that may
sound normal but can be damaging to your hearing. Hearing loss get worse every time you’re exposed 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.
Keeping the Outside Clean. Handle the device with care to maintain its appearance. To clean it, unplug all cables and turn it off. Then use a
soft, dry or slightly damp cloth. Don’t use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to
clean the device.
Carrying, Handling and Installing the device. The device contains sensitive components. Do not drop, disassemble, open, crush, bend, deform,
puncture, shred, microwave, incinerate, paint, or insert foreign objects into it.
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.
To reduce the risk of overheating , avoid installing it near heat emitting appliances, such as a room heater or stove.
No naked flame sources such as lighted candles should be placed near the device.
Operate the device in a place where the temperature is between -20°C and 50°C (-4°F to 122° F). Avoid dramatic changes in temperature or
humidity when using it, as condensation may form on or within the device.
Set your device up on a stable retaining surface. Install the unit only in a location that can structurally support the weight of the unit, far away
from people who can interfere with the stability of the system. In case of outdoor installation, assure that the wind does not interfere with the
system’s stability, taking extra securities like any certified anchoring systems. Doing otherwise may result in the unit falling down, causing
personal injury or property damage. 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.
This audio system is not intended for use in nuclear facilities, aircraft navigation or communication systems, air traffic control systems,or for any
other use where any malfunction or failure of the audio system could lead to death, personal injury, or sever environmental damage.
Do not make repairs yourself. Caution, risk of electric shock. Do not open the device, it contains potentially hazardous voltage. 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 manufacturing trained service personnel. Do not connect
the unit to an amplifier if you suspect that your device needs service or repair.

1) INPUT / PARALLEL OUT Speakon connectors. Each connector offers 2 channels of power audio signal. KMT12P and KMT18P
internal wiring is designed to pick up audio power signal from pins 1+ / 1- of a NL4 connector. 2+ and 2- pins, just like 1+ and
1-, are directly wired from one socket to the other, so the signal can pass through multiple speaker modules without additional
external cabling.

You can use either two input channels or
only one input channel.
If you use two channels you can also route
two different signals to the speakers.
Using a single KF12P as a stage monitor,
you need to feed it through a K-array KA40
amplifier module. A dedicated preset can
be easily loaded into the amplifier’s DSP
board.
You can feed the KF12P through the
powered output of a KF12MT and set up a
double monitor system.
If you need a bass reinforcement, you
can combine the KF12P with a powered
KMT18 subwoofer system which features
a 1000 W output speakon. The dedicated
preset to upload into the subwoofer unit
it’s downloadable on the K-array web site.

If you need a bass reinforcement, you can
use two active KMT18 for both you P.A.
sides (L+R), feeding a different KF12P
from each 1000 W powered output
channel.
The shape of the KF12P, provided with
two different flanges for the mounting on
a pole, allows you to configure many kinds
of set up.
PA USE
Similar to the monitor use, when you
employ the KF12P combined with a
KF12MT as a stereo P.A. system you can
connect both the main Left and Right
signal from your audio source. Then you
can route one signal to the KF12MT and
the other to the powered output socket
feeding the KF12P.
