PowerLight 3系列是我们“终极模拟”大功率放大器,专为要求最为严苛的音乐会和现场扩音应用设计。PL380均采用革命性PowerLight™电源技术,显著减轻重量,减少交流电源杂音,提升音频质量。Q-SYS联网平台可提供综合远程控制和监测功能。

  • D类拓扑结构在极端功率负载情况下,能够提供高效表现
  • 三位输入灵敏度开关保证增益匹配现有放大器机架和功率系统
  • 配置用户可禁用削波限幅器和可选低频滤波器(30 Hz,50 Hz,跨接)
  • DataPort接口支持外部放大器控制,可通过Q-SYS进行监测
  • 提供XLR和Block输入接口、接线柱或Neutrik speakON®输出接口
  • 综合内部保护系统可防止功放和扬声器电流过大、温度过高或削波影响,同时不影响演出信号

产品特点

  • PowerLight开关电源可提供最高效率,提升音频性能
  • 流通式空气通道和坚固的铝制散热器可达到最佳的散热效果
  • DataPort接口支持远程网络控制,可通过Q-SYS进行监测
  • 平滑的步进式增益控制精度为-1dB
  • 可拆卸旋钮,搭配安全外罩防止未授权操作
  • 配置用户可禁用削波限幅器,每通道可选择低频滤波器(3Hz、30Hz或50Hz)
  • 三种可选增益结构(26dB、32dB或1.2V)
  • 前后面板LED灯指示开关设置情况,一目了然
  • 并联XLR/M和XLR/F接头,支持简易环路连接
  • Neutrik Speakon® 和“防触碰”接线柱输出
  • 即使在路途中Neutrik Speakon®电源线仍有安全保证
  • 3年质保,可选择额外延保3年
  • 线性H类输出电路是B类效率的两倍,减少交流电流消耗,降低散热性能需求
  • D类输出回路提供大功率输出,降低损耗,可以将平均交流功率上升降低到最低水平,相对于旧式大功率放大器,极大减少了功率分配需求
