L-ACOUSTICS 阿酷司 K2 可变曲率WST® 线阵列音响 Products K2 可变曲率线声源阵系列 K1

K2运用K1波阵面纠正技术，被调整成适用于固定安装和巡回演出两个应用，即剧场和体育馆都适用。
K2可以与K1-SB/SB28超低频扬声器搭配使用，或者作为K1的补声扬声器，构成一个独立的系统，具 有前所未有的性能/重量比。得益于快速简便的吊挂系统，现场安装方便且快速。每个箱体之间的角
度最大可调成10°，优化垂直覆盖范围和声压级分布。水平方向，K2覆盖模式有4种：2种对称方式 （70°或110°）和2种非对称模式（90°,可设置成35°/55°或55°/35°）。
从建立之初，L-ACOUSTICS就坚持不断创新和采用科学的方法的宗旨。L-ACOUSTICS最初植根于在物理和基础声学方面，L-ACOUSTICS被誉为现代线声源阵列的鼻祖，这归功于它发明的波阵面纠正技术（Wavefront Sculpture Technology）和传奇性的V-DOSC系统。
　然而随着时间的推移，L-ACOUSTICS已经把它的研究活动拓展到结构工程，动力电子技术，信号处理和数字网络领域。L-ACOUSTICS还研发了自己内部的模拟建模工具，并通过大量的实验以验证模型的正确性。此外，L-ACOUSTICS经常在科学界发布所取得的研究成果。作为一个工程技术推动型的团队，L-ACOUSTICS是音频制造行业最受尊敬的组织之一。
产品概述：
  K1线声源阵列继承了L-ACOUSTICS 15年的波阵面纠正技术（WST）经验，并运用了L-ACOUSTICS最新研究的成果。因此，K1系统在大型音乐会、体育场馆和户外场地均表现出无可比拟的性能。
  K1 是一套适用于巡回演出的完善系统，结合4放大通道的扬声器、全新的K换能配置和提升高频部分表现的功能于一身。K1扬声器还带有专用的低频扩展（K1-SB），提供良好指向性和低频/超低频的投射能力。K1系统的出现，为远距离的投射和声音的连贯性和音调的均衡定义了新的标准。
  KUDO扬声器可作为K1的侧补声和延时扬声器，K1、KUDO和SB28均可由LA-RAK的通用电子和信号分配平台驱动。

Variable curvature WST line source

• K1 system design rescaled into a 12” compact and flexible format
• V-DOSC SPL and bandwidth, with 10° inter-element flexibility
• 100% acoustic and rigging compatibility with K1 and K1-SB
• 70°/110° symmetric and 90° (L/R) asymmetric horizontal directivity
• LA-RAK (LA8) advanced system drive and protection
• Low-weight for rigging limitations and cost-effective logistics

WST® Technology - Variable Curvature L-ACOUSTICS®pioneered the field of modern line source array as early as 1993 with the introduction of Wavefront Sculpture Technology on the legendary V-DOSC®system. Based on physical rules developed by Heil and Urban (AES 1992) the WST®theory defines five criteria for design and use of true line source arrays. At the heart of Wavefront Sculpture Technology is the internationally-patented DOSC®waveguide, which morphs the spherical wavefront of the HF driver into a cylindrical, isophasic wave. In combination with WST®, coplanar symmetry - the equivalent of coaxial assembly for HF, MF and LF drivers in vertical arrays - provides a coherent wavefront over the entire horizontal coverage at all frequencies. This behaves as if the sound was radiated by a single, continuous and articulated ribbon. Any line source featuring L-ACOUSTICS®elements respects the coplanar symmetry and all WST®criteria on the entire sonic spectrum. This allows an exceptionally coherent sonic signature in very long throw applications, beyond the limits of other systems.  L-ACOUSTICS®has been designing reference line array systems for more than 15 years.

Variable curvature, modular (KIVA and KARA)Modular line sources offer tremendous flexibility for both the installation market and rental applications. Both KIVA and KARA® systems are designed to combine a compact, high performance and lightweight enclosure with a dedicated companion LF extension (KILO, SB15m, SB18) delivering the necessary LF resources when a reinforced contour is desired. Variable curvature, large format (KUDO, V-DOSC, K2 and K1)These systems are particularly suited to large format installations and touring applications for which a reinforced LF contour is desirable. The touring systems rely on the Rental Network K platform featuring the LA-RAK plug-and-play amplification, signal processing and signal distribution rack. The amplified controllers and Network Manager deliver a “right out of the box” contour adjustable with Array Morphing to obtain an homogeneous signature in complex system configurations.
