The KR systems are integrated, self-powered speaker systems, featuring mid-hi line array elements matched to powered subwoofers. All systems feature two channels of Class D amplification housed in the subwoofer. 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-hi element with delay 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 unique four-corner port configuration gives symmetrical back loading to the sub speaker for extended bass response with very low distortion.
