安装指南
牢记安全第一！

的大部分安装与其他音响系统的安装方法相同，很多地方只需要常识即可。安全永远处于第一位。一定要使用接地插座
和三线扩展电源线。音响系统在走线时应防止绊倒，可根据需要将线缆粘贴在地上。将扬声器架和调音台放置在一个结实平整
的表面上。遵循这些指南有利于避免人员伤亡和设备损坏，确保多年无故障使用。
Avoiding Acoustic Feedback
Acoustic feedback is the loud howl or squealing sound heard through sound systems as the result of sound from the
speakers re-entering the microphones. Although it does an excellent job of getting the audience's attention, feedback

should be avoided. When trying to deal with acoustic feedback it is always best to start looking at the placement of the
mics and speakers in the system before resorting to equalization (EQ) adjustment. Make sure that the speakers are

Microphone Usage Guidelines
但是不要过度紧固（图1）。将扬声器架升到期望的高度，紧固拇指螺栓并安装安全销，如图所示（图2）。
When practical, a single microphone is preferred. Additional microphones pick up more sound from the speakers and
each mic has to be turned down a little to prevent feedback. However, if you have difficulty balancing the level of
different individuals with one mic, or if you still cannot get sufficient gain, using more mics can offer an advantage.
Giving several singers their own microphones, for example, allows placement of the microphones much closer to each
singer. This increases the volume of the sound at the mic and far outweighs any detrimental effect from using multiple
mics. It also allows the volume of each mic to be adjusted separately for proper balance.
Reverb
Adding reverberation to music can enhance the sound of that music. To add reverb to a microphone, simply turn up the
REVERB control (Fig. 7) on the appropriate input channel. Add reverb in moderation because too much reverb makes
vocals hard to understand. In most cases, it is best not to add reverb to the spoken word.
