Power amplifier is used in many fields, such as sound amplifier and electric vibration generator.
功率放大器在很多领域都得到了应用，比如音响、电动振动试验台等等。
What the senior engineer knew was the connection between two sound components — such as receiver, mixer, amplifier, and speakers — went beyond two copper wires and some insulation.
这位资深工程师所知道的就是两个音响部件之间的连接，两段铜线和一些绝缘介质之间的接收器、混音器、放大器和扬声器。
Sound headphone also requires a quality amplifier just like a top - grade loudspeaker.
靓声的耳机就如同高级的喇叭，同样需要高素质的放大器来伺候。
A method of sound detection under strong noise conditions is advanced applying the theory of differential amplifier and utilizing transducers having different sensitivities.
提出了应用差动放大理论和灵敏度不同的传感器来完成强噪声环境下微弱声信号提取的方法。
Part of the output of an amplifier can be fed back to get rid of sound distortion.
放大器的部分输出可以进行反馈以消除声音的失真。
While it had excellent sound quality, the low efficiency of the power amplifier unit made commercialization difficult.
尽管它有非常出色的音质，但是由于功率利用率低的问题，商业化是比较困难的。
Part of the output of an amplifier can be fed back to get rid of sound distortion .
放大器部分输出可以进行反馈以消除声音的失真。
Negative feedback makes the amp sound "tighter", particularly in the low end, where the speaker resonant hump has the most effect on amplifier output.
负反馈使放大器声音“更严格”，尤其是在低端，那里的一位发言者谐振驼峰拥有最影响放大器输出。
Try this configuration instead of "hookup a" in the following situations: when there are no jacks on the amplifier for a subwoofer, or when you want a stronger bass sound from the subwoofer.
如下状况时，可试用此配置代替“a式联结”：当放大器上没有副低音扬声器用的插孔时。或者：当想获得较强的来自副低音扬声器低音时。
