KMT21

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.
