CBT 70J-1 + 70JE-1 System
较大的图像

为 CBT 70J-1 线阵列柱形扬声器专门设计的扩展器,采用更坚固的网罩。

CBT 70JE-1 扩展器与 CBT 70J-1 线阵列柱形扬声器配合使用时,可提供扩展的低频响应、扩展的指向性控制和提升的声压输出级别。组合阵列系统配备恒定波束宽度技术™,这代表了指向性控制一致性的突破,采用复杂的模拟波束成形和幅度递减技术来实现卓越、一致的垂直覆盖,避免了被动柱形扬声器典型的狭窄垂直波束和覆盖外瓣。

特点

  • 组件:四个125毫米(5英寸)大功率低频驱动器(70JE-1)
  • 500瓦功率处理能力(70JE-1)
  • 内置专用分频网络,可与CBT 70J-1组合使用(70JE-1)
  • 包含耦合板(70JE-1)
  • 扩展指向性控制(±20°控制可达400赫兹,大幅轴外衰减可达200赫兹)
  • 低频响应扩展至45赫兹。
  • 组件:十六个25毫米(1英寸)软球顶高音扬声器和八个125毫米(5英寸)大功率低频驱动器。
  • 专利待审的恒定波束宽度技术™提供恒定指向性,覆盖最高频率,减少覆盖外旁瓣。
  • 垂直指向性覆盖可切换,中程应用为45°、远程应用为25°。
  • 可切换音频特性,音乐模式下提供平坦响应,语音模式下提供中频峰值提升。
  • 包含耦合板和壁挂式旋转(平移)/俯仰支架(后置插入式指向性适配第三方标准支架)。
