话筒使用技巧话筒使用技巧话筒使用技巧1话筒基本介绍如今无线话筒得到了普及以及广泛使用，市场上销售的一种无线话筒，价格在几百元左右。

该话筒采用UHF超高频段，比传统的VHF 频段干扰更少，还有独特的降噪设计，使用户在K歌过程中享受还原自己最真实的声音。

这里我们主要讲解下无线话筒在使用时的一些技巧性问题。

1、怎样选购无线话筒发射机机的电池为保证系统正常使用时不至出现信号失真和频率干扰，必须使用能是充足的电池，在选购时有条件的话最好选用碱性9V电池。

2、怎样才能尽早知道发射机电池能量是否充足在各种品牌和型号的无线话筒系统中，绝大多数接收机不具备发射机电池能量显示功能。

尽管有的无线发射器上有电池低压显示，但使用者在使用中一般很少会注意这个问题。

在无线话筒正常使用中，出现电池不足引起音频信号失真或频率干扰是时有发生的事。

为了防止发生这种现象，操作人员可在无线话筒正常使用中，适时地使用调音台PFL预听功能，用耳机监听无线话筒的信号，若声音清晰度稍有降低或噪声稍有增大时，就应马上更换电池，这样才能尽可能避免由于电池能量不足给操作者带来的心理压力。

3、怎样才能防止和避免外界对无线话筒的干扰在选购非变频无限话筒前应先弄清当地电视台的发射频率，选购时应错开电视台的发射频率免受干扰，选购多个无线话筒系统时还应注意，各系统的频率不能重复，以避免频率重叠时的相互干扰。

4、怎样消除无线话筒受外界干扰非变频的分集无线话筒系统在受到外界干扰时(指发射机电源关闭时，在接受机显示器上仍有RF射频、AF音频或DIVERSITY分集通到A、B中任一或二者的LED显示器有信号显示的话，则表明接收器正处于外界无线电波干扰)，可通过调校SQUEICH静躁器以改善接收，减少干扰。

其具体做法是，调好天线位置，发射机仍处于关闭状态，将接收机音量输出增益关死，最后顺时针方向调校SQUEICH静躁器，直至所有干扰信号消失(此时接收机除电源显示外没有任何信号显示)，再顺时针转少许，调试时一定要使用无感应螺丝刀。

USB无线K歌麦产品使用说明书（娱乐版）USB无线麦克风为专业酷我K歌电脑平台系统（电脑版）和专业版K歌设计的。

该产品采用无线2.4G通用频段技术，声音传输是通过数字化处理和传输方式，具有较强的抗干扰性，使输出的声音具有高保真的音质；接收部分是通过USB数字接口传送到电脑，可抗数模转换和电流音，是一款具有专业级的无线K 歌专用麦。

无线麦克风适用于电脑K歌、电脑录音和在线聊天、教学和商务演讲的专业工具，它的有效使用范围在30平方米内，频率响应宽度（在20～16KHz之间），它的使用效果会是称心如意，是唱K歌与商用演讲的好工具。

主要特点：※据了解是全球第一款采用USB接口技术的无线麦克风；※麦克风（话筒，又称发射器）采用锂电池供电，充一次电可以使用13-15 小时左右；※麦克风具有低压提示指示灯，提示充电；※麦克风采用电容咪与电脑的电气特性相匹配；※麦克风具有遥控电脑的功能，如：选歌和音量控制、播放暂停等；※麦克风外观采用塑胶与金属的完美结合，大小适中，有多种时尚的色彩选择可选择。

※USB接收器采用电脑USB接口技术--即插即用方式，无需安装驱动程序。

产品说明：操作说明：在使用无线麦克风系统前，首先要配对好麦克风（话筒）与USB接收器，再设置好电脑“酷我K歌”软件的相关设置项，无线麦克风系统才能正常使用。

具体操作步骤如下：第一步：麦克风（话筒）与USB接收器配对操作打开带多媒体音箱的电脑，取出麦克风（话筒）和USB接收器，用手指按住话筒的“开关键”，话筒上的指示灯的变化为：红灯亮转为蓝灯亮，再转为红蓝灯快闪，此时可以松开手指，同时把USB接收器插上电脑的USB接口上，这时USB接收器的指示灯会由快闪变为慢闪，并与话筒上的指示灯同步变为慢闪，这就说：话筒与USB接收器配对成功（配对成功后，第二次只需打开话筒和电脑系统就可直接使用；另：一支麦克风只能与一个USB接收器配套使用，要用另一支麦克风与原USB接收器使用的话，需进行重新配对。

以下是麦克风使用说明书，结合所学知识谈谈说明书翻译过程中应注意什么。
