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 congurations.

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 amplier 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 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.

4. UNPACKING

Each K-array loudspeaker 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 loudspeaker. If you nd any

damage, immediately notify the shipping company. Only the consignee may institute a claim procedure regarding the system’s electronic equipment.

5. WARRANTY

K-array systems are warranted against manufacturing defects in materials or craftsmanship over a period of 2 years from the date of original purchase. During the warranty period K-array will, at its discretion, either repair or replace products which prove to be defective provided that the product is returned in its original packaging, shipping prepaid, to an authorized K-array service agent or distributor. K-array cannot be held responsible for defects caused

by unauthorized modications, improper use, negligence, exposure to inclement weather conditions, acts of God

or accidents, or any use of this product that is not in accordance with the instructions provided by K-array. K-array

is not liable for consequential damages. This warranty is exclusive and no other warranty is expressed or implied.

This warranty does not affect your statutory rights.

6. SAFETY

• 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

8.2 VOLTAGE REQUIREMENT

8.3 CURRENT REQUIREMENT

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.

The KMT12 and KMT18’s switching power supply accommodates AC mains operating at either

115V or 230V. The KMT ampliers 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.

CAUTION

Do not connect the system to AC power mains exceeding 250V. Doing so will

cause signicant damage to the device and create serious risk for users!

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 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.

Page 12

KMT12/KMT18

REV. A

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.

OUTPUT

The KMT12 and KMT18 are powered by a 2-channel digital amplier with 1,050 W output power per channel (EIAJ test).

The KMT12 and KMT18’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).
