話筒拾音頭 MK 6
機械式開關切換:全指向形、心形和8字形
使用范圍很廣
主軸:橫向的(與話筒垂直)
在Colette系列中幾乎為“通用型”拾音頭MK 6 只使用一個振膜。當旋轉拾音頭的頂蓋
時,內部窗式系統會改變振膜周圍的聲音特性,從而會改變其指向特性,即從全指向形變為心形再變為8字形。
在全指向性設置中,拾音頭是一只到最低頻仍具有平滑響應的壓力傳聲器。(有些廠商使用雙膜來獲得可調的方向模式。但這樣會致使全向設置成為壓力梯度傳聲器,具有更明顯的固載噪聲和近講效應,而無法產生壓力傳聲器的全低頻響應。這種方式還會導致心形模式在低頻上丟失指向性。)在心形設置中,MK 6 近似 MK 4V,而在8字形設置中,它類似于MK 8 。
同 MK 8 話筒一樣,0°軸是垂直于話筒,在拾音頭底部的邊緣處用一個紅點標識出來。所標識的黑點為180°方向。

Microphone Capsule MK 6
– omni, cardioid and figure-8, mechanically switchable
– very broad range of applications
– main axis: lateral (perpendicular to the microphone
body)
– the most nearly “universal” capsule in the Colette
modular system
The MK 6 operates with a single diaphragm. Whenthe ribbed cap of the capsule is rotated, a system ofinternal shutters alters the acoustic chambering aroundthe diaphragm to change its characteristic from omnito cardioid to figure-8.
In the omnidirectional setting the MK 6 is a truepressure transducer with flat response down to thelowest frequencies. (Other manufacturers use twodiaphragms to achieve a switchable pattern arrangement. But that causes the “omnidirectional” setting tobehave as a pressure-gradient transducer, with greatervulnerability to solid-borne sound and proximity effect,while failing to produce the full low-frequencyresponse of a pressure transducer. It also causes thecardioid pattern to lose directivity at low frequencies.)
In the cardioid setting, the MK 6 closely resembles theMK 4V, while in the figure-8 setting it resembles theMK 8.
As with the MK 8, the 0° axis is perpendicular to thebody of the capsule and is indicated by a red dot atthe lower rim of the capsule. A black dot marks the180° direction.
