调试和调音
在你开起ACC电源开关或打开音响系统后， 放大器会自动接通。
功放开着的时候，它侧面电源指示灯就一直亮着。在整个机器运转
期间放大器需要车载电池提供能源。为了防止电池跑电，除非你确
定汽车是在运行状态下否则不要启动放大器。
注意：如果放大器过热的话它会暂时关闭，当它冷却后它会
自动重启。
为了达到最佳的表现力，您必须调节放大器侧面的电平旋钮（
最大/最小)使声音达到最好。
1.用螺丝刀反时针旋转电平旋钮到最小。
2.调节机头的音量在1/3位置处。
3.调节功放的电平旋钮直到达到良好、舒适的听觉效果为止。
4.调节机头的音量直到声音开始失真。然后调小一点使它刚刚没有
出现失真。
5.调节功放的电平旋钮直到调试出您想要的声音。
6.调节机头的音量直到舒适的听觉效果为止。
注意：当中间喇叭的低频受到阻塞时，增强LPF的频率并允许
高频进入低音的频率传进入中音喇叭。
Bass boost potentiometer:
When the bass is 50HZ, you can adjust from 0db-6db.
Crossover: adjust the crossover as per your installation method.
-LPF:Low Pass Filter-only(50HZ-250 HZ)
-FLAF:No filtering for speakers.Use with full-range speakers.
-HPF:High pass filter(50HZ-250 HZ)
Ground Terminal:
The ground connection should be clean, unpainted metal to provide a good
electrical connection. It is very important to avoid the noise made by
2
return circuit. We advise choose 5AWG(16mm )cable.
+12V terminal (positive pole of battery):
Connect the battery cable to the +12 volt terminal on the
amplifier. Considering security, connect the fuse holder
as closed to the vehicle battery + as possible, using 5AWG
2
(16mm ), the amperage must be lower than the total amperage
of fuse for amplifier.
Control cable connection:
The control cable is connected to the front head unit. The amplifier
will be turn on when the head unit (e.g CD player) is turned on.
LP-filter (range : 50HZ-250 HZ):
We install a filter switch on LPF, it will allow low frequencies only
and blocks higher frequencies. The normal frequency range is
from 50 to 250Hz.
HP-filter (range: 50HZ-250 HZ):
The HP-filter can block low frequencies
(50Hz-250Hz, or as per you setting frequencies).
It removes the low frequencies of front and back drivers.
A normal setting is 80-100Hz.
Power light:
The power light (green) is turned on when the amplifier is turned on.
The protect light ( red) is turned on when the amplifier shuts down
from overheating or a short circuit(speaker failure)
