JBL VTX-V25 V25-II VTX线阵系列 VTXV25全新线阵列

JBL Professional VTX V20双10英寸线阵列Loudspeaker box和VTXS25可组心形指向双15英寸超低音Loudspeakerbox，它们是已传奇于世的JBL VTX系列的新成员
  两款Loudspeakerbox与它们的前辈(V25、S28和G28)一样，都提供了无与伦比的清晰音质、高功率密度和精确的覆盖度，但它们更紧凑的设计，可以为音响租赁公司、声效设计师和系统集成商在搭建世界级现场音响扩声系统时，提供更灵活的方案。VTX V20Loudspeaker box拥有真正的3路系统设计、专有的D2双隔膜双音圈压缩驱动和Differential Drive低频传声器技术，以及申请了专利的超线性马达技术，专用于中频部件。为了保持VTX系列的整体理念，VTX V20的每一线阵列都以超高功率密度设计，包含了2个2261H 10英寸DifferentialDrive低音Loudspeaker box、4个2164H4英寸超线性中频传声器和3个新的小规格D2415K双驱动单元
哈曼JBL VTX线阵系列，一款革命性的产品，传承公司65年扬声器设计创新和突破性技术发展，专为便携式和固定地点的系统运营商设计。VTX系列采用JBL传奇音质，再加上最先进的扩声技术和支持服务。
“JBL多年来获得的所有成就中，VTX系列开创了实际应用中创意工程的一个里程碑。”JBL的Tour Sound的高级经理保罗·鲍曼表示。“在阵列中VTX真正符合下一代——JBL行业标准VERTEC®演变，预示着性能、系统集成和用户友好方面正走向一个新的时代。”
  VTX线阵列系列首发产品是VTX V25——一款全尺寸、3路高方向性线阵元素。VTX V25采用两个2000W、15英寸的Differential Drive® 低音扬声器，安装在压铸铝挡板上，4个8英寸Differential Drive中档传感器和3个革命性的新型D2双膜片双音圈压缩驱动，安装了第三代波导和专利RBI Radiation Boundary Integrator®组件。
  VTX中心是D2双驱动器，它是由JBL开发的一个革命性的设备，大大提高了高频率的声音和性能。D2克服了传统压缩驱动器技术的局限性：由于振膜和音圈的质量限制高频延伸，以及由于圆顶分散模式导致失真 。JBL专利的Radiation Boundary Integrator 把高频和VTX V25中档部分相结合，所以在每个波段转换是不间断，不失真和无缝的。专利申请tuned resonant absorption chamber (TRAC) 集成到波导本身。 VTX的RBI波导安装提供更高水平的覆盖，范围更广，更稳定。
 VTX系列吸取了来自HARMAN专业音响技术整系列的专业知识和整合成功。因此，除了尽可能最好的声音、安装、调试、网络和控制外，VTX系列还是高效、智能和真正的系统解决方案。例如，VTX系列具有Crown Audio VRack DSP和放大功能。VRack是一个坚固的机架，装有三个Crown I-Tech HD系列功率放大器、电源输入面板，可定制的输入/输出面板提供给VRack 12000和VRack 4 x 3500两种配置，可分别加载3个IT12000HD和3个IT 4×3500HD放大器。
 除了标准包性能优势可确保VTX系列机柜优化供电和处理以外，VRack确保VTX网络合作伙伴之间交叉租赁的兼容性。由于VRack提供所有组件的安装和内部连接，也无需费力机架搭建；任何组件可能不正确连接也没有机会；连接失败的机会大大降低。
 性能管理接口指南的专利工作流程范例通过完整的系统设计、配置和控制流程。在许多方面，整个流程像一个简单的一步一步安装向导。采用哈曼HiQnet Performance Manager™控制软件和测量空间响应和电路增益参考，以及JBL Line Array Control Panel面板调整作为VTX V25系统调整的第一步。一旦SPL和频率响应已优化到电路，全域均衡可以被应用到整个阵列，以弥补房间的影响。这种专利系统调音方法已特别设计到Performance Manager的工作流程。
  VTX的专利SAFE悬挂系统在速度和效率上最新优化，改进的硬件能用更少的钉扎操作和更高的安全实现更快地安装。自定义设计的防护罩和轮架使运输方便，悬挂过程快速、高效、安全的。所有悬挂的硬件集成到外壳，战略定位实现快速和安全的操作。为达到有效的安装，利用独特的Angle Stop Mechanism (ASM) ，不仅安全，而且防振。还包括提供安装Laser Sighting Module配件，实现更大的轻松和更精准于阵列焦点和系统调音。
  VTX系列符合哈曼的GreenEdge倡议，环保设计相结合，大幅节省能源，而又不妥协优异性能。像所有的JBL专业产品，VTX系列在JBL的电源测试设备中进行了全面的测试。在行业中独树一帜，在设计阶段，JBL功率测试贯穿每个部件和系统持续100个小时，高电平输入，即使是经过多年的使用和数千小时运转。也能确保系统提供非凡的声音。
“VTX系列是JBL的不懈努力的结果，提供更强大、更紧凑、重量轻和灵活的扩声系统，”鲍曼评论。“JBL已投入巨资贯穿于整个开发周期，如设计、测量、评估和改进组件等所需的工具。除了最先进的CAD系统，我们已经开发JBL独特专有的R&D工具。有了这些工具，我们确保每个产品符合设计目标，也为更出色性能寻找机会，但也许是最重要的是，我们有资源去开发新的技术。VTX系统就是一个重要的例子。”

Full Size 3-Way High-Directivity Line Array With Fixed Angle ASM Suspension
The VTX V25-II is a full size 3-way high-directivity line array element that includes a new 4th generation waveguide which improves long throw performance, wavefront control, and is an improved power match for the Crown IT4x3500HD. The transducer compliment for VTX V25-II is two 2000W 15" Differential Drive® woofers mounted in die cast aluminum baffles, four 8" Differential Drive midrange transducers firing through a patented (RBI Radiation Boundary Integrator®), and three revolutionary D2 Dual-Diaphragm Dual-Voice-Coil Compression Drivers loaded onto the newly designed waveguide. Patented rigging, Crown I-Tech HD amplification with BSS ® OmniDriveHD V5 Processing, and JBL HiQnet Performance Manager™ configuration and control software complete the system package.

TECHNOLOGY
D2 DUAL DIAPHRAGM DUAL VOICE COIL COMPRESSION DRIVER
The revolutionary D2 Dual Driver dramatically improves the sound and performance of high frequencies, providing an extreme output advantage over conventional systems with significantly higher array power, reduced distortion, double the number of voice coils and more than double the power handling. This results in a dramatic increase in pure high frequency sound pressure levels in the same physical footprint with a 30% reduction in weight.

VTX V25-II WAVEGUIDE
Improved Wavefront Control
The V25‐II waveguide provides better acoustic loading conditions for the D2 driver, resulting in 10 dB higher sensitivity above 10 kHz.

DIFFERENTIAL DRIVE® TECHNNOLOGY
Enhanced Performance and Dramatically Reduced Driver Weight
JBL's exclusive dual voice coil, dual magnetic gap Differential Drive technology is at the core of all VTX models, dramatically reducing driver weight while greatly enhancing all critical performance parameters: frequency response, power output and distortion.
