XLC Series Power Ampliers
2.7.3 Bridge Mode
Typical input and output bridge wiring is shown in figure 2.12. The input of Channel 1 will be used.
1. Set the Mode Switch to Bridge (1-OFF, 2-ON).
2. Connect Channel 1 loudspeaker’s positive (+) lead to Bridge positive (red) terminal of amp; repeat for Channel 1’s
negative (-).
2.8 Connecting to AC Mains
Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cord. First, connect the
IEC end of the cord to the IEC connector on the amplifier; then, plug the other end of the cord to the AC mains.
WARNING: The third prong of this connector (ground) is an important safety feature. Do not attempt to disable
this ground connection by using other methods.
Amplifiers don’t create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. You
must operate your amplifier from an AC mains power source with not more than a 10% variation above or below the
amplifier’s specified line voltage and within the specified frequency requirements (The specific voltage and frequency
requirement is compatible to retailer’s location and dictated on the amplifier’s back panel label). If you are unsure of the
output voltage of your AC mains, please consult your electrician.
2.9 Protecting Your Speakers
It’s wise to avoid clipping the amplifier signal. Not only does clipping sound bad, it can damage high-frequency drivers of
speakers.

2.7.3 桥接模式
图2.12为一个常用的桥接输入和输出接线示例。使用的为通道1的输入。
1. 将后面板的模式开关设定到桥接位置（1-OFF, 2-ON)；
2. 将通道1扬声器的正极（+）导线连接到功放桥接的正极（红色）端子上，用同样的方法，
连接好通道1的负极。
2.8 连接到电源
使用功放原装的电源线，将您的功放连接到电源上（电源插座）。首先，将电线的IEC端连接到
功放的IEC接口上，然后将电线的另一端插入电源插座。
警告：此接口的第三个插脚（接地端）在安全性上起着至关重要的作用。切忌试图使用
其他方法禁用此接地连接。
功放不产生能量。请确保交流电的电压和电流充足，从而供给功放所需的电能。功放所需要的交
流电源的电压不能高于或低于功放指定工作电压的10%，并符合指定的功率要求（指定的电源电
源和功率要求与经销商所在地匹配，具体数值在功放后面板的标签有标示）。如果您不能确定交
流电源的输出电压值，请咨询您当地的电工。
2.9 保护您的扬声器
在常规使用中，需避免功放接收到削波。因为削波不仅会导致声音质量变差，而且还会损坏扬声
器高频驱动单元。
