1. INTRODUCTION
The K-array KMT21 is a full-featured audio system, featuring a 21” powered subwoofer, programmable on-board
DSP and multiple analog and digital inputs and outputs for creating a wide array of speaker congurations.
The KMT 21 features 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 amplier delivers 2 x 2000 W at 4Ω, with a max THD of 1% (EIAJ test @ 1KHz). The KMT21
features multiple analog and digital outputs, including a Speakon output to connect a wide array of passive speakers including mid-high modules (KP52, KP102) or additional passive subwoofers (KMT21P). 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 conguration provides symmetrical back loading to the speakers, for extended bass response with very low distortion. The port conguration 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.

This warranty does not affect your statutory rights.
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 qualied
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 amplier, 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 amplier 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 KMT21 will operate safely, without interruption, provided the AC voltage remains within 85V- 268V, at 50 or 60 Hz. Please verify that your AC mains connection is capable of satisfying the power ratings for the device.
CAUTION
Do not connect the system to AC power mains exceeding 270V. Doing so will
cause signicant damage to the device and create serious risk for users!
8.3 CURRENT REQUIREMENT
The KMT21 presents 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 specications. 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.
For best performance, voltage drops should not exceed 10% at 115V or 5% at 230V.
REV. A10
Page 11
KMT21
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.

DELAY PAGE
8.6 AUDIO INPUT CONNECTOR WIRING
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 KMT21 is powered by a 2-channel digital amplier with 2000 W output power per channel (EIAJ test).
The KMT21’s amplier functions, including crossovers, equalization, phase response, and driver protection,
are controlled by an on-board DSP processor.
KMT series ampliers 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).
