PA-750
特点:
• 采用最先进的层级电源设计,大大提高输出效率。  
• 精心设计的"地输出"电路,配合大型散热器及变速散热风机,确保功率放大器在任何情况下都温升最低,可靠性最高,输出功率源源不绝。 
• 每个声道由独立电源供电,提供非常强劲的输出电流,提高了声道的分离度。 
• 设有完善的保护电路,包括压限保护、直流输出保护、输出短路保护、开机、关机冲击电流保护及温度保护,确保音响系统更安全可靠。 
• 工作状态指示灯,清楚显示每个声道的工作情况。 
• 备有两种卡侬输入插座,方便连接输入信号。使用国际安全标准设计的接线柱和音箱螺栓座SPENKON输出插座,确保输出连接牢固可靠。 
• 设有双声道,桥接及并接转换开关,以满足不同的使用要求。
