主要特点

LEN-150 是一款无源100伏线源扬声器,经EN 54-24 B型认证,可用于语音报警系统。与Voice Alarm 系列的所有产品一样,它配备了一个防风雨的钢筋铝外壳,使其同样适用于室内和室外使用。LEN柱形扬声器即使在困难的声学环境中也能保证出色的语音清晰度和长距离。

  • 12 ×防水涂层4 "全频单元
  • 均匀的指向性
  • 抑制不需要的旁瓣得益于Fohhn Source Division Waveguide
  • 无需额外保护即可全天候使用(保护等级 IP65,符合 IEC 529 / EN 60529 标准)
  • 新品:
  • 可提供不同的颜色(RAL经典色、Pantone色、NCS色)或与Fohhn Texture Design
  • 为确保最佳性能和运行可靠性,必须使用Fohhn 系统功放,并选择正确的扬声器预设。
