PT-70

项目编号: 1506-XXXXX

PT-70是Perform系列中一个特别强大的无源全频音箱。由于采用了Fohhn CDT,它可以在心型和全向型指向性之间进行切换。 它可以作为俱乐部或音乐会的主要音响系统,或作为大型系统的近距离覆盖。它也完全适用于大型厅堂和体育场馆的固定安装。与Perform系列的PS-800 和PS-850 子系统结合使用,该扬声器可提供出色的效果。

主要特点

  • 2×12 "压缩式驱动器,CD号筒上的1.4 "压缩驱动器
  • 可通过外壳背面的滑块切换为心形。
  • 两种型号:90°或60°水平扩散角
  • 额定功率:900W@4欧姆
  • 最大声压级:140分贝
  • 带有IPC高频保护的分频器
  • 通过中音波导的有效旁瓣抑制
  • 在心形模式下,扬声器背后有效降低达23分贝
  • 标准配备有防风雨PU涂层和表面防水涂层
  • 2个用于Quicklock支架和AEROQUIP吊挂轨道的吊挂硬件,2个用于安全的孔眼
  • 可提供广泛的配件
  • 注意:扬声器只能与Fohhn系统功放和正确的扬声器预置一起使用。
