近日，森海塞尔推出其MK8大振膜多指向电容话筒。MK 8是一直大振膜多指向性的录音棚专用电容话筒，有5种可选的指向极性(全指向、宽心形、心形、超心形和8字形)，内置低切/滚降滤波和衰减开关。
MK 8
MK 8是之前大受欢迎的MK 4的升级版，基于MK 4的经典造型，加入了更多指向性的选择。
MK 8内置一英寸溅射涂敷24K金的双振膜舱，配合弹性支架可降低结构带来的噪音。三种模式的滤波器可消除60Hz以下的噪音(-18dB/八度的低切滤波)，也可通过滚降滤波消除100Hz以下做近距离收音时带来的噪音(-6dB/八度的滚降滤波)。有-10dB、-20dB和关闭这三种衰减模式，可在拾取大音量声音时给振膜以保护。
