有人知道SM7为什么灵敏度很低啊？
做一个演播厅，竟然发现SHURE 的SM7演播话筒灵敏度非常低，竟然还不如森海塞尔的领夹话筒，距离远了，拾音效果非常差劲，不知道什么原因，望各位指教，谢谢！re:1、我不知道你说的SM7是什么？SM57...
1、我不知道你说的SM7是什么？SM57还是SM87？我就当SM87吧。<br>它的灵敏度是–52.5 dBV/Pa (2.4 mV) ——(1 Pa = 94 dB SPL)<br>
还可以啊。不过，它是近讲型的话筒，在近距离的低频会比较丰满一些。<br>

2、你对比的森海塞尔的话筒是什么型号的？ 我也有这样的问题存在，广播电台的直播室里面配置了二个SHURESM7话筒，经查，该话筒的指标不错，但是实际使用却不理想。灵敏度不如AKG的3300（3600）话筒，我用的是美奇1604VLZ3调音台，同样的增益，SHURE发输出电平要比AKG的少15dB的输出电平，郁闷，不知道这个SHURE是否假货，唉 http://www.shure.com/stellent/groups/public/@gms_gmi_web_us/documents/web_resource/site_img_us_pro_sm7b_m.jpg就是介个东东

[*]FAQ's for SM7B 好顶哦 学学!!!!!!!!!!!!!!!!!!!!!!! 我也发现舒尔的SM58拾音就是灵敏度非常低 我也发现舒尔的SM58拾音就是灵敏度非常低 要把灵敏度做高一些其实是很简单的问题，你的产品是表现人声的有线话筒，适合于欧美歌手（大嗓门）不失真也适合大陆摇滚歌手。灵敏度高了大嗓门一喊，听去像是音箱过载划破了，其实是话筒失真了（震膜超出了震动范围），调音台把音量降低也是失真的。灵敏度高低各有所长啊。很多歌手有自己喜欢的专用话筒就是这个原因。 shure产品册里没有SM7啊:dizzy:
