    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 first 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.

    KMT12/KMT18 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. 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.

    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.
