1. INTRODUCTION
The K-array KMT12 and KMT18 are full-featured audio systems featuring a powered subwoofer, programmable on-
board DSP and multiple analog and digital inputs and outputs for creating a wide array of speaker congurations.
The KMT12 features a 12” subwoofer, while the KMT18 features an 18” subwoofer.
The KMT 12 and KMT 18 feature an integrated touch screen, providing intuitive control over the main DSP
functions: input / output levels, signal routing, offset delays for subwoofer and speakon output (up to 12 ms.,
each) and overall system delay (up to 330 ms.). All DSP functions, including EQ, can also be remote controlled via
software over USB or RS485 (3-pin XLR).
The KMT series provides two balanced analog line level inputs and a two-channel AES/EBU digital input. An
integrated class D amplier delivers 2 x 1050 W at 8Ω, with a max THD of 1% (EIAJ test @ 1KHz). The KMT12 /
KMT18 feature multiple analog and digital outputs, including a Speakon output to connect a wide array of passive
speakers including mid-high modules (KK52, KK102) or additional passive subwoofers (KMT12P or KMT18P). To
optimize performance, the on-board DSP includes up to 40 programmable presets. The rst 8 have been designed
by K-array, the additional 32 slots can be used to create, save, and store personal presets using the K-framework
software.
The KMT series’ unique four-corner port conguration provides symmetrical back loading to the speakers, for
extended bass response with very low distortion. The port conguration also provides incredible structural strength
to the cabinet, despite its light weight. Pocket handles and an M20 thread mount position for attaching mid-high
speakers makes the Redline series convenient to use and ideal for medium throw applications in theaters, concert
halls, and Audio/Video installations.
All KMT components are designed by K-array and custom-made under K-array’s quality control system.

6. SAFETY
WARNING
• 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.
• Always use loudspeaker systems in a safe manner.
Never stand close to loudspeakers driven at high
volume.
• Only install the speaker in a location that can
structurally support the weight of the unit. Doing
otherwise may result in personal injury and property
damage.
• The system should only be suspended by qualied
personnel, following safe rigging practices. If
there is any doubt, seek professional help from
architects, structural engineers or other specialists
before proceeding.
• Do not operate the speaker for an extended period
of time if the sound is distorted. This is an indication
of malfunction, which can cause heat build-up and
result in a re.
• Only connect the power supply to an appropriate
power adapter.
• Do not install the speaker in wet or humid locations
without using weather protection.
• Do not allow water or any foreign object to get inside
the speaker. Do not put objects containing liquid on,
or near, the unit.
• To reduce the risk of overheating the amplier,
avoid exposing it to direct sunlight. Do not install the
unit near heat emitting appliances, such as a room
heater or stove.
• Never place open ame sources, such as lighted
candles, near the device.
• The speaker should be placed in a location that
does not interfere with its proper cooling.
• Do not attempt to disassemble the unit. The unit
contains no user-serviceable parts. Repairs should
be performed only by factory trained service
personnel.
• Be sure that the adapter has the correct voltage
value.

8. AMPLIFIER
8.1 AC POWER CONNECTOR
The amplier module and any audio equipment connected to it (mixing consoles, processors, etc.) must be
properly connected to the AC power distribution, preserving AC line polarity. All grounding points should be
connected to a single node or common point, using the same cable gauge as the neutral and line cables. Bad
grounding connections within an audio system can produce noise, hum and/or serious damage to the input/
output stages in the system’s electronic equipment.
Before applying AC to any K-array self-powered speaker, be sure that the voltage
potential difference between neutral and earth ground is less than 5 VAC.
8.2 VOLTAGE REQUIREMENT
The KMT12 and KMT18’s switching power supply accommodates AC mains operating at either
115V or 230V. The KMT ampliers will continue to operate safely, without interruption, provided the
AC voltage remains within 90 - 135V or 190 - 250V (230V), at 50 or 60 Hz. Please verify that your
AC mains connection is capable of satisfying the power ratings for the device.
KMT12/KMT18
CAUTION
Do not connect the system to AC power mains exceeding 250V. Doing so will
cause signicant damage to the device and create serious risk for users!
8.3 CURRENT REQUIREMENT
The KMT12 and KMT18 present a dynamic load to the AC mains, drawing additional current as operating
levels increase. Different cables and circuit breakers heat up at varying rates, so it is essential to understand
current ratings and how they correspond to circuit breaker and cable specications. Maximum continuous
RMS current - measured over a period of at least ten seconds - is used to calculate the temperature increase
in cables, which drives the proper size and gauge cable and rating for slow-reacting thermal breakers. Maximum burst RMS current - measured over a period of approximately one second - is used to select the rating
for fast reacting magnetic breakers.
REV. A
11
KMT12/KMT18
For best performance, voltage drops should not exceed 10% at 115V or 5% at 230V. The minimum electrical
service amperage required by a K-array loudspeakers system is the sum of their maximum continuous RMS
current. We recommend allowing an additional 30% above the minimum amperage to prevent peak voltage
drops at the service entry.

are grouped into six pages, shown as icons on the
Home page.
To reach the Home page from any other page,
touch the Home button.
The Input page allows users to independently manage
the amplitude of all the four input channels.
The Output page allows users to independently control
the amplitude of the signal routed to the Subwoofer, the
Speaker Output and the XLR DSP Output.
Three Routing pages allow users to manage the
routing of the four input channels to the three outputs
(Subwoofer, Speaker Out and XLR DSP Out) as well
independently set output volume and delay for each
output.
The delay values set in the Routing pages are summed
to the global delay assigned on the Delay page.
The arrow buttons on the top right corner of the screen
provide access to individual Routing pages for the
Subwoofer, Speaker Out and XLR DSP Out.
PRESET PAGES
INFO PAGE
Notes: The XLR DSP page does not provide control
over delay for this output.

REV. A14
DELAY PAGE
8.6 AUDIO INPUT CONNECTOR WIRING
KMT12/KMT18
The Delay page allows users to independently set
the delays for the speaker system (Subwoofer and
Speaker Out). This delay is summed with the delays
from the Routing pages of Subwoofer and Speaker
Out. The COARSE and FINE controls allow users to
change the delay in larger and smaller steps.
Notes: The delay control does not affect the XLR
DSP out. Delay for this output line can only be
managed through the K-Framework dedicated
controls.
The Audio section includes parallel LINK, which
allows users to distribute an audio signal to
multiple units. Up to 30 different modules can be
connected in parallel on the same balanced line
(with a source output impedance of 600 ohm).
CH 1 Line Input (female, balanced XLR) is
wired in parallel to CH1 Line Parallel Out (male,
balanced XLR). To create your own audio cables,
please use the following wiring diagrams:
8.7 AMPLIFICATION AND PROTECTION CIRCUITRY
The KMT12 and KMT18 are powered by a 2-channel digital amplier with 1,050 W output power per channel
(EIAJ test).
The KMT12 and KMT18’s amplier functions, including crossovers, equalization, phase response, and driver
protection, are controlled by an on-board DSP processor.
KMT series ampliers are equipped with several protection circuits to prevent damage. Two independent
audio limiters – Clip Limiter and Average Power Limiter – protect the internal circuitry against overload. A
Peak Current Shut Down protects the output stage with a tripping point at 35A. If tripped, Peak Current Shut
Down will reset after 2 seconds. A Temperature Protection Limiter also ensures the output stage stays below
a temperature of 85° C (approximate temperature of output power device).
