尊敬的Magnat-用户,
有了轿车音响功率放大器 POWER CORE FOUR,您便能在车内随心所欲,去追求最佳的播放音质。 无论是因它不同凡响
的超低音所需功率储备,低失真因数,还是做普通的播放,POWER CORE FOUR 赋予车内音响播放最优新质量。放大器
以其低工作电流,快速转换能力和极为出色的恒温性能成为出类拔萃的音响器材精品。通过交接电路,两个放大器声道交
接于一个放大器,而获取更高的输出功率,改善了动态效果。请您来亲身体验这套高科技设备是如何给您带来完美优雅的
听觉享受。在此我们祝您乐趣无穷,丽声悠悠......
在安装和使用放大器之前,请您先认真阅读安装说明书。

· 可调节的低音校正器
· 3/4声道
· 可无级调节的高通滤波器
· DUPE 电路将1、2通道(带通和低音增强)滤波器输出信号复制到3、4通道。
· 可调节式输入敏感
· 可桥接式4-/2声道运作方式
· 三模式运作方式
· 防短路、直流电压位移和过高温度的电子保险电路
· 哑音电路,消减开机噪声
· 接超低音音箱放大器的低电平输出口 (Cinch-接口)
· 运作显示灯(绿色LED)和超载显示灯(红色LED)
3. 安装前的重要注意事项
· 本机只能与负接地的12伏电源系统连接使用。
· 鉴于功率消耗而散热,所以需要有空气流通良好的安装场地。还有极为重要的一点是: 不要让冷却器的冷却叶片贴在
铁皮板 或一个表面上,因为这样会限制空气的流通。不得将放大器安装在狭小的或空气不流通的空间 (例如备用轮的
凹坑或车内的 地毯下)。我们建议装在汽车后箱里。
· 安装时,尽可能地使放大器避免受到震荡,沾染灰尘和污垢。
· 请您注意使输入和输出电线离电源电线有足够的距离,否则会出现干扰辐射。
· 请您注意在安装完毕后将保险和操作用的部件存放在方便之处,可以随时拿到。
· 安装的质量决定着设备的效果和可靠性。尽可能让专业人员进行安装,尤其是与多个音箱或在一个复杂的多路系统内的
安装。
