K-Array KR802 High Performance Self-Powered Stereo System

Description

Details

The K-Array KR802 is a self-powered amplification system featuring two channels of class D amplification housed in the subwoofer. The rear panel provides input for a balanced line signal, a balanced microphone signal with phantom power and digital signals in AES/EBU protocol also on an XLR for ease of cabling.

The KR802 features two of the KMT218's which are much more than a standard 2 x 18” powered subwoofer. The amplifier mounted on board is class D, delivering 2 x 2400 W at 4Ω. One of the two amplifying channels is dedicated to an output Speakon to connect to many kinds of speaker configurations, including single mid-high modules (KY102, KP52, KP102), multiple line arrays, or the passive version of an additional bass module (KMT218P, KMT18P or KMT21P). The rear panel provides input for a balanced line signal, a balanced microphone signal with phantom power, and digital signals in AES/EBU protocol, also on an XLR for ease of cabling. An integrated touch screen provides intuitive managing and editing of powerful DSP controlling: Input and output levels, In/Out routing, speakon output delay, subwoofer delay, overall system delay (up to 330 ms). All DSP functions, including EQ can be controlled with remote managing software via USB or RS485, again conveniently on a standard XLR. To optimize performance, the onboard DSP includes presets to drive K-array speakers.

The chassis features large ports designed to be fully symmetrical to the speakers, which means the back loading on the drivers is consistent and even with no port air turbulence. This also gives 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 KMT218 convenient to use and ideal for medium throw applications in theaters, concert halls, and Audio/Video installations.
