Kenwood KFC-W2511 Instruction Manual

安装
1. 将建伍提供的模板放在面板上 , 然后标出孔的位置。
2. 按照标出的位置开出一个大孔 , 并且开一些用于固定扬声器的螺钉孔。
3. 揭开密封海绵的不干胶贴 , 将胶面粘贴在扬声器的固定边沿的背面 , 这样会使安装面同安装面板
更好的贴合。

系统连接
首先 , 检查功率放大器的功率。如果功率放大器的额定功率高于副低音扬声器的额定输入功率 , 请
增加扬声器的数量或者降低功率放大器的增益 , 使输入扬声器的功率低于扬声器的额定输入功率。
输入功率大于扬声器额定输入功率会导致扬声器发出噪音或者扬声器的损坏。同时 , 如果使用多扬
声器连接 , 请注意扬声器的总阻抗。请根据功率放大器的阻抗来改变扬声器的连接方式。

请将功率放大器的增益调至与 CD 播放器或者调频调幅接收机的预置输出值接近
的数值。
Installation
1. Place the supplied template on the panel and then mark the hole positions.
2. Cut open a large hole and make screw holes.
3. Peel off the covering sheet from the spacer, and attach the spacer on the back of the speaker flange so
that the flange is completely covered.

System connections
First, check the power of the amplifier. If the power of the amplifier is higher than the subwoofer's rated
input power, increase the number of subwoofers so that the power fed to each subwoofer is lower than
its rated input power, or lower the sensitivity of the amplifier. Supplying power greater than its rated input
power of the subwoofer will cause noise and/or breakage. Also, if using multiple subwoofers, be careful
about the total impedance. Change the connecting pattern of the speakers according to the capable
impedance of the amplifier.
