4061-OC-C-B00 d:screet? CORE 4061 微型電容話筒,全指向,高聲壓,黑色

d:screet? CORE 4061 低靈敏度全指向話筒，具有非常干凈、細(xì)節(jié)豐富及自然的音質(zhì)。由于初是為在劇院、電視及對(duì)樂(lè)器進(jìn)行近距離拾音等應(yīng)用場(chǎng)合與無(wú)線系統(tǒng)一起使用而設(shè)計(jì)的，因此 d:screet? CORE 4061低靈敏度微型全指向話筒非常不易被察覺(jué)。由于其小巧的尺寸，它展現(xiàn)出非常精確的全指向覆蓋圖形，從而無(wú)需直接對(duì)準(zhǔn)音源就能獲得高品質(zhì)的拾音。

這一話筒與d:screet? CORE 4061 高靈敏度微型全指向話筒在聲學(xué)上是完全一樣的，但它的靈敏度經(jīng)過(guò)調(diào)整以便與市場(chǎng)上一些更為靈敏的發(fā)射機(jī)相匹配。

話筒可以承受144 dB削波前峰值聲壓級(jí)，使得話筒可用于小軍鼓、吉它/貝司音箱或其它高聲壓級(jí)的音源。d:screet? CORE 4061 有四種顏色可選:黑色、棕色、肉色和白色。
