RMX 2450a

双通道功率放大器


产品特点

  • 外形紧凑 — 两个机架位可提供2500W功率,三个机架位可提供5000W功率
  • 大电流环形变压器,阻抗2欧姆时功率更高,噪音更低
  • 独立削波限幅器,减少失真,支持用户自行禁用
  • 可选低频滤波器(30Hz或50Hz)保护扬声器、增加动态余量
  • 4000W RMX4050a使用标准15A插头(120V)
  • RMX4050a和RMX5050a均拥有双单通道、大电流电源,提升可靠性和性能表现
  • RMX4050a兼具卓越的散热能力和电效率,提供稳定的散热性能,适合为阻抗为2欧姆立体声或阻抗4欧姆时桥接应用持续提供高功率输出。
  • 平衡1/4”(6.3毫米)TRS,XLR和接线柱输入
  • 防触碰接线柱和Neutrik Speakon®输出接口
  • 增益控制安装在正面,便于操作
  • 信号和削波LED指示灯,可监测性能表现
  • 每个通道均配置独立DC和热过载保护,自动保护放大器和扬声器
  • 3年质保,可选择额外延保3年
