1. The main components of the KR system include the following: KR full frequency range components work in the bandwidth of 55 Hz to 20 kHz. SB18 free low-frequency expansion components, working in the range of 32 Hz are equipped with D70 amplifier controller.
2. Compared with the previous generation line, KR provides a considerable number of sources of improvement, especially in the direction of horizontal plane control, sensor resources, in order to improve operating bandwidth and consistency, improve vertical coverage capabilities and a wide selection of operating modes , To adapt to various LF profile requirements. With a fixed horizontal directivity of 110 ° and vertical elements varying from 0 ° to 10 °, KR is fully configurable to match different sound reinforcement locations. Utilizing unparalleled features through WST (Wavefront Sculpture Technology), KR provides clear, precise and unique proximity effects, providing the audience with an unparalleled listening experience.
3. As an independent system, its compact size and low weight comply with rigging and visual limitations. KR can be deployed as a compact distributed solution for delays and fills, dedicated stadium and arena concert applications, or as a FOH system. Due to its full compatibility with the SB18 extension, all applications can be set up extremely quickly.
