监控拾音器报价是多少？

大概在500元左右，拾音器，又称*头。拾音器是用来采集现场声音的器件，它是由咪头（麦克风）和音频放大电路构成。拾音器一般分为数字拾音器和模拟拾音器，数字拾音器就是通过数字信号处理系统将模拟的音频信号转换成数字信号并进行相应的数字信号处理的声音传感设备。模拟拾音器就只是用一般的模拟电路放大咪头采集到的声音。拾音器有三线制和四线制之分；三线制拾音器一般红色代表电源正极，白色代表音频正极，黑色代表信号及电源的负极（公共地）。四线制拾音器一般红色代表电源正极，白色代表音频正极，音频负极和电源负极是分开来。拾音器产品通常分为有源和无源两种类型；按性能分有声乐吉他和监控用拾音器。

10元左右，拾音器安装位置的选择：拾音器可以在天花板,墙面安装。拾音器安装位置尽量离主要的谈话区域较近就可以。比如，审讯室可以安装在被审人附近;教室可以安装在讲台附近;小型会议室可以安装在天花板中央。原则：尽量靠近主要的谈话区域，这样的拾音效果更佳

五行缺智商 07-30 11:00

监控拾音器优点1、高保真低噪声处理芯片。2、高级咪抑制环境噪声。3、金属外壳灵敏度可调节。4、防爆场所专用。5、内置降噪处理电路。6、电源极性保护电路。参考价格38元左右

隔岸观火 07-30 11:17

监控拾音器报价在：40元左右；
前期拾音器多采用高增益、内部频率补偿的双运算放大器：3558，LM358，NE5532等，从而实现信号放大及降噪作用。在此类拾音器中，由于只采用简单的RLC选频网络，会出现噪音去除不干净的现象。高性能拾音器，产品内置数字降噪及浮点相位处理芯片，可以最大限度地降低噪音，还原人声，适合于性能要求高的环境。

在拾音器演进中，模拟拾音器将会被数字拾音器所超越。数字拾音器增加了时钟电路、储存器、数字处理器。识别数字拾音器的办法：用一个喇叭播放人的声音，另外一个人在同样距离说话，带回声抑制功能的拾音器会拾取人说话的声音而喇叭播放的声音会被抑制。
应用于中国航空航天、国防重点工程、*事指挥系统、*用*装备、高铁列车车厢、银行金融系统、证券交易所、监狱监仓、探访室、公检法审讯室、巡逻、*车载指挥车、公交车、地铁、派出所、法院庭审、司法督察、高速公路收费站、服务窗口、大厅、戒毒所、工商（税务）调解室、档案馆、博物馆、*所、机杨安检通道、边检口岸、海关哨所、*院、学校多媒体课室、教室讲台、会议室主席台、投标室、评标室、拍卖行、广播广电、*广场、街道、*机关大门、*队岗哨、室外旷野同步录音录像等各个领域，总之需要对声音进行采集。
