PLX2502

低阻抗功率放大器

低阻抗功率放大器PLX2502采用轻量级PowerLight电源,在阻抗为4欧姆时的每通道功率为750W,在阻抗为2欧姆时的每通道功率为1250W,是要求最为严苛的现场音效应用的理想选择。

产品特点

  • 重量极轻(“02”型为9.5千克/21磅,“04”型为5.9千克/13磅)。
  • 散热设计可将热空气从正面排出,避免机架温度过高。流通式散热器,无需配置滤清器,避免其阻碍空气流通。
  • 前面板配备LED电源指示灯、削波指示灯、-10dB指示灯和信号指示灯,便于系统监控和故障检测。02型配备桥接和并联模式LED指示灯。
  • 两个Speakon® NL4输出连接器可正向锁死扬声器连接。上方连接器的四个极可提供双通道输出(通道1:1+,1-;通道2:2+,2-),可用来桥接单声道或双功放扬声器。
  • 21档位前面板增益控制,可精确重复性调整功率放大器。
  • 平衡XLR输入及并行TRS接口,支持所有种类输入接口和环路运行。
  • PowerLight电源技术受专利保护,其他专利也在申请中。
  • Speakon® NL4接口和接线柱输出。

  • 100Hz高通和低通滤波器支持双功放重低音扬声器和卫星箱系统,无需外接分频器。

  • 可开关/可禁用33Hz次声滤波器,保护低音扬声器,避免超出冲程。

  • 可开关/可禁用削波限幅器。

  • 四种型号在阻抗为2欧姆时的每通道额定功率可达1800W,桥接4欧姆阻抗时的每通道额定功率可达3600W

  • 采用PLX技术,为无需桥接和2欧姆立体声运行的应用提供卓越音质和性能。

  • 两个型号在阻抗为4欧姆时的每通道额定功率可达900W。

  • 削波限幅器可保护扬声器;热限制器确保异常过载情况下仍可正常运行。
