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 configurations. 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.).
KMT21 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 find any damage, immediately notify the shipping company. Only the consignee may institute a claim procedure regarding the system’s electronic equipment. 5.

KMT21 8. AMPLIFIER 8.1 AC POWER CONNECTOR The amplifier 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.
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.

KMT21 1) CH1 Line Input. XLR line level input with +4 dBu sensitivity. 2) CH2 Mic/Line Input. XLR input, with selectable sensitivity for Mic (-30 dBu) or Line (+4 dBu). 3) CH1 Parallel Line Out. XLR parallel output, providing a direct signal from the CH1 Line Input. This output cannot be processed or controlled via the K-Framework software 4) Phantom Power switch. Turns phantom power (48V) on/off on CH1 and CH2 inputs. 5) Mic/Line switch.
KMT21 8.5 TOUCH SCREEN FUNCTIONS HOME PAGE The main functions of the onboard DSP can be managed with the integrated touch screen. Functions 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.
KMT21 DELAY PAGE 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. 8.
