Contractor precision系列4"功放

Summary & Images Specs Where to buy Downloads & Support

4条功放通道，每条通道可以作为低阻抗或高阻抗运行，每条通道输出功率最高可达500W；Phoenix型输入和输出连接；远程on/off机触点；背装式衰减器；用于可选的RCM-810卡的模块插槽，支持IRIS-Net控制和监视；可选的RCM-810卡，能在IRIS-Net中进行VLD配置，并牟每条输出通道功率进行配置，以便与2-10 Ω的任何负载相匹配，负载增幅为0.1Ω；在Hi-Z模式下运行时，采用50 Hz高通滤波器；D类设计，可实现最佳效率；配有保护箱

CPS4.5是Electro-Voice的4通道功放，采用了突破性的D类技术，以实现功放效率最大化。可以输出2Ω、4Ω、70V或100V线路，无需变压器。此外，功放通道可以成对桥接，使输出功率翻倍。用于可选的RCM-810远程控制模块的模块插槽具备控制网络功能，支持通过IRIS-Net软件以及可变负载驱动（VLD）进行远程系统诊断。
