首先连接放大器地线端子和电池负极。连接的质量非常重要。必须细心地清除电池接点处残余的污垢。松动的接头会导致
功能故障或干扰噪音和失真。
这时用一根配有内装保险的电源电线连接放大器的 +12 V电源接口和电池的正极。保险应设在电池附近,为了保证安全,
从电池正极到保险的电线长度必须在60 cm以下。在所有的安装工作结束后,包括音箱的连接也完成之后再装保险。
现在将车内音响接收器的遥控线路接到放大器的REM 控制插口。放大器的遥控接口和控制器之间用一根截面为0,75 mm²
的电线连接即可。
4.2音响信号电线
在汽车内汽车收音机的Cinch-输出接口和放大器的 Cinch-输入接口之间安装音响信号线时,必须注意,避免将信号线和供
电电线铺放在汽车的同一侧。最好是作空间分离式安装,即将电源电线铺放在左侧的线槽里而信号线则铺放在右侧的线槽
里,或者反过来。这样可以减小音响信号受干扰而产生的串音。
音量遥控器的连接电线也是如此,这根线不要和电源电线放在同一边,而是应和音响信号电线放在一起。
4.3音箱的连接
· 最小终端电阻倍增为1 欧。
· 如果把两个MAGNAT Power Core One Limited 放大器在主-辅-模式下桥接运作,最小终端电阻为2欧。
· 切勿将音箱的负极端子接通汽车车身。
· 切勿将 +12 伏电源与音箱的输出相接。否则会损毁放大器终极。
如果放大器以过低的终端值工作或者如上述操作不当,则会导致放大器本身以至于音箱的损坏。在这种情况下产品
不能享受厂家提供的保修服务。
5. 操作部件和输入/输出口
5.1调节输入灵敏度
输入灵敏度可经调节而适配各个车内收音机或录音机。将您收音机的音量调节钮转到中间位置,然后调节输入电平调节器
(4) 直到获得中等音量。在这个调节位置一般能保证在最佳噪音电压间距状态下具备足够的功率储备。
注意: 大音量调试信号不宜长时间播放,以免损坏喇叭。
5.2有可调过渡频率的低通滤波器
在调节器 (5) 调出所需的过渡频率。通过这个方法可以使滤波器转而满足所用的低音音箱的音质要求。滤波器的高边缘
度将精确地降低中频和高频区。
5.3低音过滤器
借助低音功能降低最低音频。降低的幅度可以用调节器 (6) 无级调节。这样可以利用喇叭过大的盖膜冲程来有效地减小失
真,而同时又不必降低所用的低音音平。
5.4低音放大
借助低音放大功能 (7) 可以消校正重低音频率过于突出或失真。
5.5音量调节遥控器
随产品一起收到的遥控器的功能是调节音量。安装时要注意遥控器的电线不要和放大器的电源电线铺设在汽车的同一边。
遥控器应安装在仪表盘上或接触方便的地方。这时可以随意调节超低音音箱的音量,而不受收音机音量状态的限制。
5.6增接放大器的输出口/主/从模式
在主-辅-模式下,由一个音源来同时控制两个放大器。这时主放大器的控制调节(喇叭,滤波器调节)将被辅放大器取
代。
在主/从模式下“主”放大器的预放大输出信号(MASTER OUT (2))将传输给”从”放大器的输入口(SLAVE IN (1)),
图4a/4b的 显示。”主”放大器(A)的开关(9)将调到”MASTER OUT“位置,”从”放大器(B)的开关(9)则调在 ”SLAVE
IN“。
5.7相位调节器
相位调节器(8)的作用是优化超低音音箱和卫星音箱之间的相位特性曲线和频率特性曲线。
