KR PORTABLE SYSTEM

1. INTRODUCTION

The KR systems are integrated, self-powered speaker systems featuring mid-high line array elements
matched to powered subwoofers. All systems feature two channels of Class D amplification housed in
the subwoofer(s). The rear panel provides input for 2 balanced line signals and a digital signal in AES/
EBU protocol. And with the K-dante accessory, the system can be used in a Dante network.
An integrated touch screen provides intuitive managing and editing of powerful DSP controlling: input
and output levels, In/Out routing, subwoofer delay up to 12 ms, Speakon output to the mid-high element
with delay of up to 12 ms, and 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.
The Mark I version is the newest version of the KR102, KR202 and KR402 systems, featuring new auto
range amplifiers, new codecs that reduce the signal/noise ratio, a 5v dc power connector on the rear
amplifier panel and enhanced functionality for creating presets. The output AES/EBU is now latency-free
(through) and other updates include a larger LCD screen (2.8"), the removal of the e-fun connector and
a new paint job for the mid-high elements. All these features are included in the KR802 as well.
All KR systems are designed by the K-array R&D department and custom made under the K-array quality
control system.
